How is carpet made?

Background

Carpet is a textile floor covering that is distinguished from the more general term "rug" by being fixed to the floor surface and extending wall to wall. The earliest peoples covered the floors of their dwellings with animal skins, grass, or, later, woven reed mats. When people learned how to spin cotton and wool, woven mats of these materials largely replaced earlier coverings. Around 3000 B.C. Egyptians sewed brightly colored pieces of woolen cloth onto linen and placed it on their floors.

The first carpets of note were woven by nomads. The thick carpets were easy to transport and were placed over the sand floor of tent dwellings. Early looms were similarly easy to transport. Two forked branches were joined by a crosspiece holding the suspended warp, and a wooden bar was used to flatten binding weft threads, while the loose warp ends formed the carpet's pile. The Pazyryk carpet has been documented as the earliest hand loom carpet, dating back from 500 B.C. and discovered in a tomb located in the Alti Mountains in Central Asia.

From these early beginnings, carpet weaving rose to its highest art form in Turkey, Iran, India, and China. Using cotton, linen, or hemp as the foundation, and wool or silk as the luxurious pile, weavers would make a knot out of the pile thread, then form a row of knots that was tightly beaten down. The process was time-consuming: some of the finest handmade carpets have as many as 2,400 knots per square inch (372 knots per sq cm). The brilliant colors of these ancient carpets came from natural dyes such as madder, indigo, genista, woad, and ocher. Some weavers added alum to these dyes to fix the color, and a few wove gold and precious jewels into their carpets.

While Europeans for centuries eagerly received carpets ready-made from the Middle East, carpet making itself did not find a firm foothold on the continent until France imported Moorish weavers around A.D. 1300. By 1600, carpet guilds were flourishing around Aubusson and Savonnerie. England also imported Persian weavers, as well as French ones, and by 1700 both Wilton and Axminster, known for their wool, were chartered carpet-making towns. Carpet making in Europe started with the "Brussels weave" in France and Flanders. This weave is formed by putting yarn over rods to create uncut loops. Wilton carpets are cut by a blade that replaces the rod in the Brussels weave. In 1801, Joseph M. Jacquard invented a device for handlooms that used punch cards to place up to six varieties of yarn colors in textiles, thus increasing production. This technique was adopted for carpet looms in 1825.

The first carpet factory in the U.S. was built by William Sprague in Philadelphia in 1791. His looms, based on English inventions, could make 27-inch (69-cm) runners that could be sewn together to make larger carpets. By 1800, 6-8 yards (7-9 m) of carpet could be made in a day. Erastus Bigelow built a mill in 1825 in Clinton, Massachusetts, and invented the power loom in 1839, which doubled carpet production. He also invented the first broadloom in 1877. Power looms improved over the years; soon one loom could make 75 yards (82 m) of high quality carpet a day.

Carpet production changed dramatically at the beginning of the 20th century, beginning inauspiciously with a burst of tufted bedspread production in Dalton, Georgia, led by young entrepreneur Catherine Evans Whitener. Tufting is the process of punching yarn into a ground fabric to create many uncut loops at a very fast pace. Tufted bed-spread factories dominated the Dalton area by World War II, and they soon began producing tufted rugs as well. Demand for these roughly made rugs was as great as that for the bedspreads. At first using cheap, readily available cotton before switching to synthetic yarns, the number of Dalton carpet makers grew as they produced great amounts of relatively easy-to-make broadloom tufted rugs and, eventually, carpets. Carpet, once a luxury, became affordable for most Americans. Today, carpet makes up 72% of all flooring, with tufted carpet being 91.5% of production, and the city of Dalton is responsible for over 70% of the world's production of carpet.

Raw Materials

Carpet consists of dyed pile yarns; a primary backing in which the yarns are sewn; a secondary backing that adds strength to the carpet; adhesive that binds the primary and secondary backings; and, in most cases, a cushion laid underneath the carpet to give it a softer, more luxurious feel.

Ninety-seven percent of pile yarns today are made up of synthetic polymers; the rest of the yarns are wool and comprise the more expensive, woven carpet. Synthetics are plastics such as nylon (which is in 66% of all carpet), acrylics (15%), polyester (less than 15%), and polypropylene (less than 5%). These pile yarns are dyed using a variety of organic chemical compounds, or occasionally, organometallic complexes.

Both the primary and secondary backing are largely made of woven or nonwoven polypropylene, though some secondary backing may still be made of jute, a natural fiber that, when woven, looks like burlap. The adhesive used to bind the backings together is almost universally synthetic rubber latex. The most common padding is rebond (bonded urethane), though various forms of synthetic latex, polyurethane, or vinyl might be used instead. Rebond is recycled scrap urethane that is chopped into uniformly sized pieces and pressed into layers. Although rare, some carpet cushioning is made up of horse hair or jute. A plastic top sheet is usually added to the top to insure a smooth surface against the carpet.

The Manufacturing
Process

Since most carpet in the U.S. is tufted; earlier methods of weaving carpet, such as Wilton and Axminster, are ignored in the following account.

Preparing the yarn

  • Synthetic yarns arrive at the carpet manufacturer either in staple fiber form or bulk continuous filament form. The staple fibers, which average 7 inches (18 cm) long, are loose, individual strands that arrive in bales. Several bales are blended together into one batch in a hopper. Then, after lubrication, they are spun into long, loose ropes called slivers by a carding machine. The slivers are then pulled, straightened, and spun into single yarn that is wound onto spools. Both the single-ply staple fibers (now spun into filament) and the bulk continuous filament must now be twisted together to form thicker twoply yarn suitable for tufting. The yarns are then steamed to bulk them, and then heated to 270-280°F (132-138°C). This heat setting causes the yarn to maintain its shape by fixing its twist. After cooling, these yarns are wound onto tubes and transported to the tufting machines.

Dyeing the yarn

  • Most carpets are dyed after tufting, yet sometimes the yarns are dyed first. The methods include putting 500-1,000 pounds (227-455 kg) of fiber into pressurized vats through which treated dyes are circulated, or passing the fiber continuously through the bath, or passing skeins of yarn through the vat of dye. The yarn can also be put on forms, and the heated dyes can then be forced under pressure from inside the forms to color the yarn. Another method passes the yarn through printing rollers, while yet another involves knitting the yarn onto a form that is then printed with dyes before the yarn is unraveled. All yarn that has been dyed is then steamed, washed, and dried.

Tufting the carpet

  • The yarn is put on a creel (a bar with skewers) behind the tufting machine, then fed into a nylon tube that leads to the tufting needle. The needle pierces the primary backing and pushes the yarn down into a loop. Photoelectric sensors control how deeply the needles plunge into the backing, so the height of the loops can be controlled. A looper, or flat hook, seizes and releases the loop of yarn while the needle pulls back up; the backing is shifted forward and the needle once more pierces the backing further on. To make cut pile, a looper facing the opposite direction is fitted with a knife that acts like a pair of scissors, snipping the loop. This process is carried out by several hundred needles (up to 1,200 across the 12 foot [3.7 ml width), and several hundred rows of stitches are carried out per minute. One tufting machine can thus produce several hundred square yards of carpet a day.

Dyeing the tufted carpet

  • For solid color carpeting, carpet of several standard roll lengths is sewn together to make a continuous roll, which is then fed into a vat. The vat is filled with water, which is first heated before dyes and chemicals are mixed in. The mixture is then slowly brought to a boil and cooked for four hours. Another method of making solid color carpet is to sew several rows together to make one continuous roll, which is then fed under rods that bleed the color into the pile. After dyeing, the carpet is then steamed to fix the color, excess color is washed off, and the carpet is dried and put on a roll.
  • To make printed carpet of various designs, white carpet passes under screens in which holes in the desired pattern have been cut. The desired color is squeegeed through the holes in the screen, and the carpet is advanced 36 inches (91 cm) to a different screen that applies a new color in a different design through the screen. Up to eight colors can be applied with this method.
  • Another method of dyeing printed carpet is to pass it under embossed cylinders that have raised portions in a design, which press color into the carpet. Each cylinder provides a different design for a different color. After dyeing, the printed carpet is steamed, excess dyes are washed off, and the carpet is then dried and put onto rolls to go to the finishing department.

Finishing the carpet

  • The ends of the dyed carpet are first sewn together to form a continuous belt. This belt is then rolled under a dispenser that spreads a coating of latex onto the bottom of the carpet.

    At the same time, a strong secondary backing is also coated with latex. Both of these are then rolled onto a marriage roller, which forms them into a sandwich and seals them together.

    The carpet is then placed in an oven to cure the latex.

  • The completed carpet is then steamed, brushed, vacuumed, and run through a machine that clips off any tufts that rise above its uniform surface. The carpet is then rolled into 120 foot (37 m) lengths that are then packaged in strong plastic and shipped to either the carpet manufacturer's inventory warehouse or to a retail carpet store.

Quality Control

Every piece of carpet that is tufted is inspected to see if any tufts are missing. One person with a single needle tufting gun shoots pile yarn wherever holes are found. Each piece of carpet is then inspected. The manufacturer checks that the piece is of the proper dimensions and that the tuft height is of the desired length. The static shock potential is also tested.

Most states require a flammability test. A prepared 9 × 9 inch (23 × 23 cm) specimen is placed on a steel plate that has a hole 8 inches (20 cm) in diameter in its middle. A methenamine tablet is ignited in the center. If the charred portion in seven out of eight trials does not reach to the circumference of the hole, the carpet passes. Another important test determines the carpet's resistance to wear. A specimen of carpet is placed in a drum and beaten with a steel ball that has rubber studs on it for 20,000 to 50,000 revolutions. The carpet should look fairly new after this test. To test how the carpet's color stands up to sunlight, a standard light source that simulates sunlight is directed at a specimen, which is then rated according to the number of units of exposure required to produce visible loss of color.

The mass per unit area of pile yarn is a significant test because pile density determines the feel of the carpet. First, the synthetic yarn is removed from the carpet, either by physical means (it is ripped off the primary backing) or chemical means (it is dissolved off). The yarn is then dissolved in a solvent, then dried in an oven to remove the solvent. The dry residue is then weighed and checked to see if the mass is as specified for that type of carpet. Each type of synthetic fiber has its own recipe. Nylon, the most commonly used synthetic yarn, is dissolved in hydrochloric acid and dried 15 minutes at 77°F (25°C).

Backing fabrics and carpet padding are tested for strength by being pulled in a vise until they break. The primary backing's strength is checked both before and after tufting. The delamination strength of the secondary backing is also tested by determining at what force the secondary backing can be pulled away from the primary backing.

Part of the quality control process is up to the customer, who must select carpet of the proper strength and durability for the amount of traffic expected in the room, vacuum regularly, and have the carpet professionally deep cleaned at least once a year.

Carpet Types and Modern Manufactures

A few classifications-Oriental, European handwoven, Brussels, Wilton, velvet, Axminster, chenille, ingrain, rag, hooked, straw, and fiber-embrace the entire range of carpets, both antique and modern.

To the first class belong not only the genuine antique Orientals, made through the 19th cent. and now comparatively rare, but also the modern reproductions. The materials are dyed either with traditional vegetable dyes or modern (and less desirable) aniline dyes and then woven. Many modern Orientals are washed in chlorine solutions to give an effect of age or in glycerine to simulate the luster of fine wool. Commercial methods have somewhat standardized and debased the characteristic ancient patterns, but the modern Orientals are still commercially important. Moreover, some traditional Oriental rugs are still produced, incorporating the deep, rich color and intricate patterns of Persia, the brighter hues and conventionalized figures of Asian Turkey, the simpler designs and primitive colorings of Turkistan and the Caucasus, and the symbolic ornament of China.

A limited number of European handwoven carpets, both Aubussons (tapestry) and Savonneries (pile), are now made in most Western countries. Modern commercial carpets are woven on complex and highly specialized machines, a development from Bigelow's power loom. Brussels carpet has a warp and weft of linen, with a pile of worsted yarn drawn into loops by means of wires. It is called three-, four-, or five-frame, depending on the number of bobbins carrying different-colored warp threads, which make the pattern. Tapestry Brussels is an inexpensive single-frame sort, either yarn printed or piece printed.

Wilton is made on the same principle, except that the loops that form the pile are cut as they are woven into place. Velvet is an equivalent of tapestry Brussels with the pile cut. Axminster, similar in effect to Oriental, uses unlimited colors in design made on machines that loop the tufts, one color at a time, and then interlock the weft about them. Chenille, or chenille Axminster, is made in two stages. First the chenille thread, or fur, as it is called, is made, then it is folded and ironed so that the woolen fibers are like a fringe along a cotton or linen chain. This fur is then woven into a strong backing of linen with the nap on the surface.

Ingrain, no longer widely used, is a plain-weave fabric, of two- or three-ply woolen weft on a concealed cotton warp. Rag carpets, made of used rags sewn together for warp, were first woven on household looms; they became commercially important in the latter part of the 19th cent. Hooked rugs are made of narrow strips of woolen cloth drawn by a pointed hook through a canvas foundation on which a design is indicated.

Early History

Carpets were formerly woven to protect the body from cold, to be spread on a dais or before a seat of honor, to cover a table, couch, or wall, or to form the curtains of a tent. There is evidence of the existence of handwoven carpets in antiquity. On the rock tombs of Beni Hassan, Egypt, c.2500 B.C., men are depicted with the implements of rug weaving. Other evidence of the early use of rugs is seen in the drawings on the ancient palace walls of Nineveh.

Oriental Carpets

In the mountainous regions of the East stretching from Turkey through Persia and Central Asia into China, where the fleece of the sheep and the hair of the camel and goat grow long and fine, the art of carpet-weaving reached its height early in the 16th cent. The artisan worked on a handloom consisting essentially of two horizontal beams on which the warp (the vertical threads) was stretched; on the lower one the finished carpet was rolled while the warp unrolled from the upper one. The yarn for the pile, spun and dyed by hand, was cut in lengths of about 2 in. (5.1 cm) and knotted about the warp threads, one tuft at a time, after one of the two established ways of tying-the Ghiordes, or Turkish, knot and the Senna, or Persian, knot.

After a row of knots had been placed across the width of the loom, two or more weft, or horizontal, threads of cotton or flax were woven in and beaten into place with a heavy beater, or comb. The tufts, or pile, thus appeared only on the face of the fabric, which when completed was sheared to perfect smoothness. Although the hair of the camel and the goat was used in the weaving of Oriental rugs, the wool of the sheep was the essential component. Beautiful silk rugs interwoven with gold thread were also made in the 16th and 17th cent. To some degree, the quality of a carpet depends on the materials used and the number of knots per square inch of surface, which may vary from 40 to 1,000. Also produced in these regions are the geometrically patterned and flat woven rugs known as kilims.

European Carpets

In 1608, King Henry IV of France established weavers in the Louvre. About 20 years later an old soap works, the Savonnerie, near Paris, was converted to carpet weaving, and its name remains attached to one of the finest types of handmade carpet, now made at the Gobelin tapestry factory. Tapestries for walls and floors were made at Aubusson at an early date.

In 1685 the revocation of the Edict of Nantes scattered skilled Protestant carpetmakers over Europe. Centers of weaving were established in England, first at Kidderminster (1735) and later at Wilton and Axminster. Cheaper, more easily manufactured floor covering soon came into demand, and the making of ingrain, or reversible, carpets began at Kidderminster. The weavers of Flanders had made a loom that produced a pile by looping the worsted warp threads, and this loom, although guarded, was copied by a Kidderminster weaver; soon many looms in England were making Brussels carpet. Axminster was England's headquarters for imitation Oriental, or tufted-pile, carpet.

Until about 1840 all carpets were made on handlooms with such devices and improvements as could be operated by hand or foot power; then Erastus Bigelow's power loom (first used in 1841), which made it possible for carpets to be mass produced, revolutionized the industry. Although handmade rugs are still produced in some countries, e.g., Turkey, carpet manufacturing has become a highly mechanized industry, notably in the United States, Great Britain, Canada, Belgium, and Japan.

Other Rugs

In North America the Navajos and other tribes have for generations produced substantial rugs without pile, woven somewhat in the manner of tapestry on simple handlooms. In the palaces of Montezuma remarkable floor coverings were found that utilized the plumage of birds. The primitive use of rushes or straw has survived in the form of Chinese and Japanese mattings.

Swatches of Berber carpet

A carpet is a textile floor covering consisting of an upper layer of "pile" attached to a backing. The pile is generally either made from wool or a manmade fibre such as polypropylene, and usually consists of twisted tufts which are often heat-treated to maintain their structure.

Contents

Etymology

The term "carpet" derives from Old Italian carpita, "carpire" meaning to pluck.[1][2] Sometimes the term "carpet" is used interchangeably with the term "rug". Only with the opening of trade routes in the 17th century were significant numbers of Persian rugs introduced to Western Europe. Historically the word was also used for table and wall coverings, as carpets were not commonly used on the floor in European interiors until the 18th century.

Carpet types

Woven

The carpet is produced on a loom quite similar to woven cloth. The pile can be plush or berber. Plush carpet is a cut pile and berber carpet is a loop pile. There are new styles of carpet combining the two styles called cut and loop carpeting. Normally many colored yarns are used and this process is capable of producing intricate patterns from pre-determined designs(although some limitations apply to certain weaving methods with regard to accuracy of pattern within the carpet). These carpets are usually the most expensive due to the relatively slow speed of the manufacturing process.

Needlefelt

These carpets are more technologically advanced. Needle felts are produced by electrostatic attraction of individual synthetic fibres forming an extremely durable carpet. These carpets are normally found in the contract market such as hotels etc. where there is a lot of traffic.

Knotted

On a knotted pile carpet (formally, a supplementary weft cut-loop pile carpet), the structural weft threads alternate with a supplementary weft that rises at right angles to the surface of the weave. This supplementary weft is attached to the warp by one of three knot types (see below), such as shag which was popular in the 1970s, to form the pile or nap of the carpet. Knotting by hand is most prevalent in Oriental rugs and carpets. Kashmir carpets are also hand-knotted.

Tufted

These are carpets that have their pile injected into a backing material, which is itself then bonded to a secondary backing comprising a woven hessian weave or a man made alternative to provide stability. This is the most common method of manufacturing of domestic carpets for floor covering purposes in the world.

Others

A flatweave carpet is created by interlocking warp (vertical) and weft (horizontal) threads. Types of oriental flatwoven carpet include kilim, soumak, plain weave, and tapestry weave. Types of European flatwoven carpets include Venetian, Dutch, damask, list, haircloth, and ingrain (aka double cloth, two-ply, triple cloth, or three-ply).

A hooked rug is a simple type of rug handmade by pulling strips of cloth such as wool or cotton through the meshes of a sturdy fabric such as burlap. This type of rug is now generally made as a handicraft.

Embroidery

Unlike woven carpets, embroidery carpets are not formed on a loom. Their pattern is established by the application of stitches to a cloth (often linen) base. The tent stitch and the cross stitch are two of the most common. Embroidered carpets were traditionally made by royal and aristocratic women in the home, but there has been some commercial manufacture since steel needles were introduced (earlier needles were made of bone) and linen weaving improved in the 16th century. Mary Stewart Queen of Scots is known to have been an avid embroiderer. 16th century designs usually involve scrolling vines and regional flowers (for example, the Bradford carpet). They often incorporate animal heraldry and the coat of arms of the maker. Production continued through the 19th century. Victorian embroidered carpet compositions include highly illusionistic, 3-dimensional flowers. Patterns for tiled carpets made of a number of squares, called Berlin wool work, were introduced in Germany in 1804, and became extremely popular in England in the 1830s. Embroidered carpets can also include other features such as a pattern of shapes, or they can even tell a story.

Production of knotted pile carpet

Both flat and pile carpets are woven on a loom. Both vertical and horizontal looms have been used in the production of European and Oriental carpets in some colors.

The warp threads are set up on the frame of the loom before weaving begins. A number of weavers may work together on the same carpet. A row of knots is completed and cut. The knots are secured with (usually one to four) rows of weft.

There are several styles of knotting, but the two main types of knot are the symmetrical (also called Turkish or Ghiordes) and asymmetrical (also called Persian or Senna).

Flag of Turkmenistan

Contemporary centers of carpet production are: Kashmir ( India / Pakistan ), Tabriz ( Iran ), Afghanistan, Azerbaijan, Turkey, Northern Africa, Nepal, Spain, Turkmenistan, and Tibet.

The importance of carpets in the culture of Turkmenistan is such that the national flag features a vertical red stripe near the hoist side, containing five carpet guls (designs used in producing rugs).

Kashmir (India) has World Famous Handknotted carpets. These are usually of Silk and some woolen carpets are also woven.

Child labour has often been used in Asia. The Rugmark labelling scheme used throughout Europe and North America assures that child labour has not been used: importers pay for the labels, and the revenue collected is used to monitor centres of production and educate previously exploited children.[3]

Fibres and yarns used in carpet

Carpet can be made from many single or blended natural and synthetic fibres. Fibres are chosen for durability, appearance, ease of manufacture, and cost. In terms of scale of production, the dominant yarn constructions are polyamides (nylons) and polypropylene with an estimated 90% of the commercial market.[4]

Nylon

Nylon is the most common material for construction of carpets. Both nylon 6 and nylon 66 are used. Nylon can be dyed topically or dyed in a molten state (solution dying). Nylon can be printed easily and has excellent wear characteristics. In carpets Nylon tends to stain easily because it possesses dye sites on the fibre. These dye sites need to be filled in order to give Nylon any type of stain resistance. As nylon is petroleum-based it varies in price with the price of oil.

Polypropylene

Polypropylene is used to produce carpet yarns because it is inexpensive. It is difficult to dye and does not wear as well as wool or nylon. Polypropylene is commonly used to construct Berber carpets. In this case, polypropylene is commonly reffered to as olefin. Large looped olefin Berber carpets are usually only suited for light domestic use and tend to mat down quickly. Berber carpets with smaller loops tend to be more resilient and retain their new appearance longer than large looped Berber styles. Commercial grade level-loop carpets have very small loops, and commercial grade cut-pile styles are well constructed. When made with polypropylene these styles wear very well, making them very suitable for areas with heavy foot traffic such as offices. Polypropylene carpets are known to have good stain resistance but not against oil based agents. If a stain does set, it can be difficult to clean. Commercial grade carpets can be glued directly to the floor or installed over a 1/4" thick, 8-pound density padding. Outdoor grass carpets are usually made from polypropylene.[5]

Wool and wool-blends

Wool has excellent durability, can be dyed easily and is fairly abundant. When blended with synthetic fibres such as nylon the durability of wool is increased. Blended wool yarns are extensively used in production of modern carpet, with the most common blend being 80% wool to 20% synthetic fibre, giving rise to the term "80/20". Wool is relatively expensive and consequently a small portion of the market.

Polyester

The polyester known as "PET" (polyethylene terephthalate) is used in carpet manufacturing in both spun and filament constructions. After the price of raw materials for many types of carpet rose in the early 2000s, polyester became more competitive. Polyester has good physical properties and is inherently stain-resistant because it is hydrophobic, and, unlike nylon, does not have dye sites. Color is infused in a molten state (solution dyeing). Polyester has the disadvantage that it tends to crush or mat down easily. It is typically used in mid- to low-priced carpeting.

Another polyester, "PTT" (Polytrimethylene terephthalate) , also called Sorona or 3GT (Dupont)or Corterra (Shell), is a variant of PET. Lurgi Zimmer PTT was first patented in 1941, but it was not produced until the 1990s, when Shell Chemicals developed the low-cost method of producing high-quality 1,3 propanediol (PDO), the starting raw material for PTT Corterra Polymers. PTT is similar to polyester, but its molecules have a "kink", similar to a spring, that makes the fibre more crush resistant, resilient, and easy to clean. PTT also does not have dye sites, and is inherently stain resistant because color is infused in a molten state. Carpets made with PTT dry quickly and are resistant to mold.[6]

The binding in woven carpet is usually cotton and the weft is jute.

Carpet binding

Carpet binding is a term used for any material being applied to the edge of a carpet to make a rug. Carpet binding is usually cotton or nylon, but also comes in many other materials, such as leather. Natural binding, in other words, binding not made from synthetic material is frequently used with bamboo, grass, and wool rugs, but is often used with carpet made from other materials.

Early carpets

The Pazyryk Carpet, among the oldest surviving carpets in the world

The hand-knotted pile carpet probably originated in southern Central Asia between the 3rd and 2nd millennium BCE, although there is evidence of goats and sheep being sheared for wool and hair which was spun and woven as far back at 6000BC.[1]

The earliest surviving pile carpet in the world is called the "Pazyryk Carpet", dating from the 5th-4th century BCE. It was excavated by Sergei Ivanovich Rudenko in 1949 from a Pazyryk burial mound where it had been preserved in ice in the valley of Pazyryk. The origin of this carpet is attributed to either the Scythians or the Persian Achaemenids. This richly colored carpet is 200 x 183 cm (6'6" x 6'0") and framed by a border of griffins.[7]

The earliest group of surviving knotted pile carpets was produced under Seljuk rule in the first half of the 13th century on the Anatolian peninsula. The eighteen extant works are often referred to as the Konya Carpets. The central field of these large carpets is a repeated geometrical pattern. The borders are ornamented with a large-scale, stylized, angular calligraphy called Kufic, pseudo-Kufic, or Kufesque.[8]

Chinese Carpets

As opposed to most antique rug manufactory practices, Chinese carpets were woven almost exclusively for internal consumption. China has a long history of exporting traditional goods; however, it was not until the first half of the 19th century that the Chinese began to export their rugs. Once in contact with western influences, there was a large change in production: Chinese manufactories began to produce art-deco rugs with commercial look and price point.

The centuries old Chinese textile industry is rich in history. While most antique carpets are classified according to a specific region or manufactory, scholars attribute the age of any specific Chinese rug to the ruling emperor of the time. The earliest surviving examples of the craft were produced during the time of Ch'ung Chen, the last emperor of the Chen Dynasty, which ended when he died in the early 17th century. The Qing Dynasty, the last before the creation of the Chinese Republic, succeeded the Chen dynasty.

Persian and Anatolian carpets

The Persian carpet is a part of Persian (Iranian) art and culture. Carpet-weaving in Persia dates back to the Bronze Age.

The earliest surviving corpus of Persian carpets come from the Safavid dynasty (1501–1736) in the 16th century. However, painted depictions prove a longer history of production. There is much variety among classical Persian carpets of the 16th and 17th century. Common motifs include scrolling vine networks, arabesques, palmettes, cloud bands, medallions, and overlapping geometric compartments rather than animals and humans[citation needed]. This is because Islam, the dominant religion in that part of the world, forbids their depiction[citation needed]. Still, some show figures engaged either in the hunt or feasting scenes. The majority of these carpets are wool, but several silk examples produced in Kashan survive.[9]

Iranian carpets are the finest in the world and their designs are copied by weavers from other countries as well. Iran is also the world's largest producer and exporter of handmade carpets, producing three quarters of the world's total output and having a share of 30% of world's export markets.[10][11][12][13] Iran is also the maker of the largest handmade carpet in history, measuring 60,546 square feet.[14][15][16]

Turkish carpets

Carpets, whether knotted or flat woven (kilim) are among the best known art forms produced by the Turks. They have protected themselves from the extremes of the cold weather by covering the floors, and sometimes walls and doorways, with carpets. These are handmade, of wool or sometimes cotton, with occasional additions of silk. Even technological advances which enable factory-made carpets has not stopped the production of rug weaving at cottage-industry level. Although synthetic dyes have been in use for the last 150 years, hand made carpets are still considered far superior to industrial carpeting.

Turkish carpets in the 15th and 16th centuries are best known through European paintings. For example, in the works of Lotto (15th century Italian painter) and Holbein (16th century Germanpainter), Turkish carpets are seen under the feet of the Virgin Mary, or in secular paintings, on tables. In the 17th century, when the Netherlands became a powerful mercantile country, Turkish carpets graced many Dutch homes. The Dutch painter Vermeer represented Turkish carpets predominantly[citation needed]to indicate the high economic and social status of the persons in his paintings. Turkey carpets, as they were known, were too valuable to be put on floors, except under the feet of the Holy Mother and royalty[citation needed].

The Turkish carpets have exuberant colors, motifs, and patterns. Because traditionally women have woven the carpets, this is one art form that is rarely appreciated as being the work of a known or a specific artist.[17]

Pakistani carpets

The art of weaving developed in the region comprising Pakistan at a time when few other civilizations employed it. Excavations at Moenjodaro and Harappa - ancient cities of the Indus Valley civilization - have established that the inhabitants used spindles and spun a wide variety of weaving materials. Some historians consider that the Indus Valley civilization first developed the use of woven textiles.

Carpet weaving may have been introduced into the area of present-day Pakistan as far back as the eleventh century with the coming of the first Muslim conquerors, the Ghaznavids and the Ghauris, from the West. It can with more certainty be traced to the beginning of the Mughal Dynasty in the early sixteenth century, when the last successor of Timur, Babar, extended his rule from Kabul to India to found the Mughal Empire. Under the patronage of the Mughals, Indian craftsmen adopted Persian techniques and designs. Carpets woven in the Punjab at that time (often called Lahore carpets today) made use of motifs and decorative styles found in Mughal architecture.

During the Mughal period, the carpets made on the Indian subcontinent became so famous that demand for them spread abroad. These carpets had distinctive designs and boasted a high density of knots. Carpets made for the Mughal emperors, including Jahangir and Shah Jahan, were of the finest quality. Under Shah Jahan's reign, Mughal carpet weaving took on a new aesthetic and entered its classical phase.

At present, hand-knotted carpets are among Pakistan's leading export products and their manufacture is the second largest cottage and small industry. Pakistani craftsmen have the capacity to produce any type of carpet using all the popular motifs of gulls, medallions, paisleys, traceries, and geometric designs in various combinations.[18]

Oriental carpets in Europe

Oriental carpets began to appear in Europe after the Crusades in the 11th century. Until the mid-18th century they were mostly used on walls and tables. Except in royal or ecclesiastical settings they were considered too precious to cover the floor. Starting in the 13th century Oriental carpets begin to appear in paintings (notably from Italy, Flanders, England, France, and the Netherlands). Carpets of Indo-Persian design were introduced to Europe via the Dutch, British, and French East India Companies of the 17th and 18th century.[19]

Spanish carpets

Although isolated instances of carpet production pre-date the Muslim invasion of Spain, the Hispano-Moresque examples are the earliest significant body of European-made carpets. Documentary evidence shows production beginning in Spain as early as the 10th century AD. The earliest extant Spanish carpet, the so-called Synagogue carpet, is a unique survival dated to the 14th century. The earliest group of Hispano-Moresque carpets, Admiral carpets (also known as armorial carpets), has an all-over geometric, repeat pattern punctuated by blazons of noble, Christian Spanish families. The variety of this design was analyzed most thoroughly by May Beattie. Many of the 15th-century, Spanish carpets rely heavily on designs originally developed on the Anatolian Peninsula. Carpet production continued after the Reconquest of Spain and eventual expulsion of the Muslim population in the 15th century. 16th-century Renaissance Spanish carpet design is a derivative of silk textile design. Two of the most popular motifs are wreaths and pomegranates.[20]

French carpets

In 1608 Henry IV initiated the French production of "Turkish style" carpets under the direction of Pierre Dupont. This production was soon moved to the Savonnerie factory in Chaillot just west of Paris. The earliest, well-known group produced by the Savonnerie, then under the direction of Simon Lourdet, are the carpets that were produced in the early years of Louis XIV's reign. They are densely ornamented with flowers, sometimes in vases or baskets, against dark blue or brown grounds in deep borders. The designs are based on Netherlandish and Flemish textiles and paintings. The most famous Savonnerie carpets are the series made for the Grande Galerie and the Galerie d'Apollon in the Palais du Louvre between c. 1665-1685. These 105 masterpieces, made under the artistic direction of Charles Le Brun, were never installed, as Louis XIV moved the court to Versailles in 1688. Their design combines rich acanthus leaves, architectural framing, and mythological scenes (inspired by Cesare Ripa's Iconologie) with emblems of Louis XIV's royal power.

Pierre-Josse Perrot is the best-known of the mid-eighteenth-century carpet designers. His many surviving works and drawings display graceful rococo s-scrolls, central rosettes, shells, acanthus leaves, and floral swags. The Savonnerie manufactory was moved to the Gobelins in Paris in 1826.

The Beauvais manufactory, better known for their tapestry, also made knotted pile carpets from 1780 to 1792. Carpet production in small, privately owned workshops in the town of Aubusson began in 1743. Carpets produced in France employ the symmetrical knot.[20]

English carpets

Knotted pile carpet weaving technology probably came to England in the early 16th century with Flemish Calvinists fleeing religious persecution. Because many of these weavers settled in South-eastern England in Norwich the 14 extant 16th and 17th century carpets are sometimes referred to as "Norwich carpets." These works are either adaptations of Anatolian or Indo-Persian designs or employ Elizabethan-Jacobean scrolling vines and blossoms. All but one are dated or bear a coat of arms. Like the French, English weavers used the symmetrical knot. There are documented and surviving examples of carpets from three 18th-century manufactories: Exeter (1756–1761, owned by Claude Passavant, 3 extant carpets), Moorfields (1752–1806, owned by Thomas Moore, 5 extant carpets), and Axminster (1755–1835, owned by Thomas Whitty, numerous extant carpets). Exeter and Moorfields were both staffed with renegade weavers from the French Savonnerie and, therefore, employ the weaving structure of that factory and Perrot-inspired designs. Neoclassical designer Robert Adam supplied designs for both Moorfields and Axminster carpets based on Roman floor mosaics and coffered ceilings. Some of the most well-known rugs of his design were made for Syon House, Osterley Park House, Harewood House, Saltram House, and Newby Hall. Six of Axminster carpets are known as the "Lansdowne" group. These have a tripartite design with reeded circles and baskets of flowers in the central panel flanked by diamond lozenges in the side panels. Axminster Rococo designs often have a brown ground and include birds copied from popular, contemporary engravings. Even now a large percentage of the 55,000 population town still seek employment in this industry. The town of Wilton, Wiltshire is also known for its carpet weaving, which dates back to the 18th century.

Modern carpeting and installation

Macro shot of Berber carpet. Berber carpets are a style of carpet containing big and small tufts. It uses a cut pile construction type, and usually contains small flecks of dark color on lighter shade background colors.

Carpet is commonly made in widths of 12 and 15 feet in the USA, 4m and 5m in Europe. Where necessary different widths can be seamed together with a seaming iron and seam tape (formerly it was sewn together) and it is affixed to a floor over a cushioned underlay (pad) using nails, tack strips (known in the UK as gripper rods), adhesives, or occasionally decorative metal stair rods, thus distinguishing it from rugs or mats, which are loose-laid floor coverings. For environmental reasons, the use of organic wool, natural bindings, natural padding, and formaldehyde-free glues is becoming more common. These options are almost always at a premium cost, though with no sacrifice to performance.

Machine used to cut and re-roll carpet lengths

In the UK some carpets are still manufactured for pubs and clubs in a narrow width of 27" (0.69m) and then sewn to size. Carpeting which covers an entire room area is loosely referred to as 'wall-to-wall', but carpet can be installed over any portion thereof with use of appropriate transition moldings where the carpet meets other types of floor coverings. Carpeting is more than just a single item; it is, in fact, a system comprising the carpet itself, the carpet backing (often made of latex), the cushioning underlay, and a method of installation.

Carpet tiles are also available, typically 50 cm square. These are usually only used in commercial settings and are affixed using a special pressure-sensitive glue, which holds them into place while allowing easy removal(in an office environment, for example) or to allow rearrangement in order to spread wear.[21]

Dalton, Georgia produces 90% of the USA's carpeting, rugs, and hardwood flooring[citation needed]. It is sometimes referred to as the carpet capital of the world. Over 150 production plants and more than 100 wholesale outlets are based in the Dalton Area (Whitfield County, Georgia and Gordon County, Georgia).
