weaving
Production of fabric by interlacing two sets of yarns so that they cross each other, normally at right angles, usually accomplished with a hand- or power-operated loom. In weaving, lengthwise yarns are called warp and crosswise yarns are called weft, or filling. Most woven fabrics are made with their outer edges finished in a manner that avoids raveling (because the weft yarn turns around instead of ending in a cut end). These edges, called selvages, run lengthwise, parallel to the warp yarns. The three basic weaves are plain or tabby (weft threads go over one warp thread, then under one), twill, and satin. Fancy weaves, such as pile, Jacquard, dobby, and leno, require more complicated looms or special loom attachments. See also Navajo weaving.

Weaving

Top

The weaver's craft was known in the ancient Near East from early times. In Palestine it was mainly wool from sheep and goats that was used, as is known from the Bible and from a considerable number of garments of the Roman period that have come to light in the Judean Desert Caves. From the Bible we learn that the wool was spun (Ex 35:25-26) on a spindle with the help of a distaff (Prov 31:19). The spindle consisted of a rod about 3 feet (1m) long, at the end of which were one or two weights. These weights, hundreds of which have been found on sites inhabited from the Iron Age and later, were made of wood, clay, bone or stone. The method of spinning was quite simple and does not differ essentially from the one used today by Bedouin women. The fibers of wool are placed in a ball on the distaff, which is held under the left arm, and the spindle is held in the left hand. The wool is plucked from the distaff with the right hand and drawn on to the spindle, which is turned at great speed, so producing the yarn. There are variations in the method of using the spindle, however.

The yarn so spun (cf Ex 35:25) was washed and cleaned with niter and soap (cf Jer 2:22) and was then ready for dyeing (see DYES AND DYEING). The yarn was placed in a pot or basin containing a weak solution of the dyeing pigment and then transferred to another pot, in which the final stage of dyeing took place in a more concentrated solution. The dyed yarn was then rinsed in clean water and subsequently left to dry. It was now ready for weaving. Horizontal hand looms were used; they were placed on the ground and consisted of two parallel rows of pegs driven into the ground, to which the warp threads on which the actual weaving was done were attached. The process is referred to in Judges (16:14).

Another type of loom, much employed in Egypt and also used in Palestine, was vertical. Two long posts were driven into the ground and a third was placed horizontally on top of them. The warp threads were tied to the horizontal post, each thread being suspended by a weight. Loom weights made of stone have been found on almost every site in Palestine. The horizontal post of the vertical loom is the "weaver's beam" referred to in I Samuel 17:7.

On hand looms such as these either monochrome or polychrome fabrics were produced. Joseph's coat of many colors (Gen 37:31), or Aaron's "skillfully woven tunic" (Ex 28:4) may have been of the latter kind, as may the "plunder of garments embroidered and dyed" of Sisera (Judg 5:30). If multicolored cloth was to be made groups of fibers of different colors were tied to the horizontal beam. It was not until late in the Roman period that more advanced systems of weaving were introduced.

[Ge]

The use of wool, cotton, silk, flax, or some other plant or animal fibre yarn or thread to produce textiles of various sorts by criss-crossing the yarns together in at least two directions. Warp threads are those which run up and down the length of a piece of textile, weft threads are those that run across the weave at right angles to the warp. Many different patterns are possible, producing different kinds of textile and styles of weave. Patterns can be introduced by using different coloured threads in a set order. The earliest evidence of weaving is that represented as textile and flexible basketry impressions on burnt clay from Pavlov in the Czech Republic which date to between 25 000 and 23 000 bc. The oldest woven cloth so far discovered is made from flax, dates to about 7000 bc, and comes from Çayönü, Turkey.

 
weaving, the art of forming a fabric by interlacing at right angles two or more sets of yarn or other material. It is one of the most ancient fundamental arts, as indicated by archaeological evidence. Discoveries in the early 1990s in the Czech Republic point to a possible origin in the Paleolithic period some 27,000 years ago. Moreover, the earliest literatures often mention the products of the loom. In primitive cultures weaving was practiced mainly by women.

Although weaving sprang up independently in different parts of the world and was early known in Europe, its high development there in the Middle Ages was brought about by Eastern influences operating through Muslim and Byzantine channels of culture. Byzantium became a center of silk weaving in the 6th cent. In the 9th cent. Greece, Italy, and Spain became proficient. In Flanders a high degree of skill was attained by the 10th cent., especially in the weaving of wool. Flemish weavers brought to England by William the Conqueror and later by Queen Elizabeth I gave a great impetus to the craft there, and Lancashire became an important center. Tapestry weaving was brought to a high art in France. In colonial America weaving was a household industry allied with agriculture.

The 18th-century weaving and spinning inventions marked the transition from the old era of domestic craftsmanship to the tremendous, organized industry of today. The factory system of machine weaving produces quantities of standardized material for mass consumption; the result is a loss of the distinctive elements of quality and design. Some of the finest silks, velvets, table linens, and carpets are still woven on handlooms.

The Weaving Process

The first step in weaving is to stretch the warp, or longitudinal, yarns, which must be very strong. The weft, woof, or filling crosses the warp, binding the warp threads at either side to form the selvage. The three essential steps after the warp is stretched are: shedding, or raising every alternate warp yarn or set of yarns to receive the weft; picking, or inserting the weft; and battening, or pressing home the weft to make the fabric compact. In most primitive weaving these operations were performed by the hands alone, as in making rush mats and baskets. Gradually frames for holding the warp evenly stretched and devices for throwing the weft came into use (see loom).

Types of Woven Fabrics

Woven fabrics are classified as to weave or structure according to the manner in which warp and weft cross each other. The three fundamental weaves, of which others are variations, are the plain, twill, and satin. In plain weave, also known as calico, tabby, taffeta, or homespun weaves, the weft passes over alternate warp threads, requiring two harnesses only. The relatively simple construction suits it to cheap fabrics, heavy yarns, and printed designs. Variations are produced by the use of groups of yarns, as in basket weave and monk's cloth, or by alternating fine and coarse yarns to make ribbed and corded fabrics, as the warp-ribbed Bedford cord, piqué, and dimity and the weft-ribbed poplin, rep, and grosgrain. The second primary weave, twill, shows a diagonal design made by causing weft threads to interlace two to four warp threads, moving a step to right or left on each pick and capable of variations, such as herringbone and corkscrew designs. Noted for their firm, close weave, twill fabrics include gabardine, serge, drill, and denim. Satin weave has floating or overshot warp threads on the surface which reflect light, giving a characteristic luster. When the uncrossed threads are in the weft, the weave is called sateen.

Pile fabrics have an additional set of yarns drawn over wires to form loops, and may be cut or uncut. Warp-pile fabrics include terry and plush; weft-pile, velveteen and corduroy. In double-cloth weave two cloths are woven at once, each with its warp and filling threads, and combined by interlacing some yarns or by adding a fifth set. The cloth may be made for extra warmth or strength, to permit use of a cheaper back, or to produce a different pattern or weave on each surface, e.g., steamer rugs, heavy overcoating, and machine belting. Velvet is commonly woven as a double cloth. In swivel weaving, extra shuttles with a circular motion insert filling yarns to form simple decorations, such as the dots on swiss muslin. Figure weaves are made by causing warp and weft to intersect in varied groups. Simple geometric designs may be woven on machine looms by using a cam or a dobby attachment to operate the harnesses. For curves and large figures each heddle must be separately governed. The Jacquard loom attachment permits machine weaving of the most complicated designs.

Warp and weft in plain weaving

Weaving is the textile art in which two distinct sets of yarns or threads, called the warp and the filling or weft (older woof), are interlaced with each other to form a fabric or cloth. The warp threads run lengthways of the piece of cloth, and the weft runs across from side to side.

Cloth is woven on a loom, a device for holding the warp threads in place while the filling threads are woven through them. Weft is an old English word meaning "that which is woven".[1]

The manner in which the warp and filling threads interlace with each other is known as the weave. The three basic weaves are plain weave, satin weave, and twill, and the majority of woven products are created with one of these weaves.

Woven cloth can be plain (in one colour or a simple pattern), or it can be woven in decorative or artistic designs, including tapestries. Fabric in which the warp and/or weft is tie-dyed before weaving is called ikat.

The ancient art of handweaving, along with hand spinning, remains a popular craft. The majority of commercial fabrics in the West are woven on computer-controlled Jacquard looms. In the past, simpler fabrics were woven on dobby looms, while the Jacquard harness adaptation was reserved for more complex patterns. Some believe the efficiency of the Jacquard loom, with its Jacquard weaving process, makes it more economical for mills to use them to weave all of their fabrics, regardless of the complexity of the design.

Process

An Indian weaver preparing his warp

In general, weaving involves the interlacing of two sets of threads at right angles to each other: the warp and the weft. The warp are held taut and in parallel order, typically by means of a loom, though some forms of weaving may use other methods. The loom is warped (or dressed) with the warp threads passing through heddles on two or more harnesses. The warp threads are moved up or down by the harnesses creating a space called the shed. The weft thread is wound onto spools called bobbins. The bobbins are placed in a shuttle which carries the weft thread through the shed. The raising and lowering sequence of warp threads gives rise to many possible weave structures:

Both warp and weft can be visible in the final product. By spacing the warp more closely, it can completely cover the weft that binds it, giving a warpfaced textile such as rep weave. Conversely, if the warp is spread out, the weft can slide down and completely cover the warp, giving a weftfaced textile, such as a tapestry or a Kilim rug. There are a variety of loom styles for hand weaving and tapestry. In tapestry, the image is created by placing weft only in certain warp areas, rather than across the entire warp width.

Ancient and traditional cultures

Prehistoric woven objects and weaving tools

There are some indications that weaving was already known in the Palaeolithic era. An indistinct textile impression has been found at Pavlov, Moravia. Neolithic textiles are well known from finds in pile dwellings in Switzerland. One extant fragment from the Neolithic was found in Fayum at a site which dates to about 5000 BCE. This fragment is woven at about 12 threads by 9 threads per cm in a plain weave. Flax was the predominant fibre in Egypt at this time and continued popularity in the Nile Valley, even after wool became the primary fibre used in other cultures around 2000 BCE. Another Ancient Egyptian item, known as the Badari dish, depicts a textile workshop. This item, catalogue number UC9547, is now housed at the Petrie Museum and dates to about 3600 BCE. Enslaved women worked as weavers during the Sumerian Era. They would wash wool fibers in hot water and wood-ash soap and then dry them. Next, they would beat out the dirt and card the wool. The wool was then graded, bleached, and spun into a thread. The spinners would pull out fibers and twist them together. This was done by either rolling fibers between palms or using a hooked stick. The thread was then placed on a wooden or bone spindle and rotated on a clay whorl which operated like a flywheel.

The slaves would then work in three-woman teams on looms, where they stretched the threads, after which they passed threads over and under each other at perpendicular angles. The finished cloth was then taken to a fuller.

Easton's Bible Dictionary (1897) points to numerous Biblical references to weaving in ancient times:

Weaving was an art practised in very early times (Ex. 35:35). The Egyptians were specially skilled in it (Isa. 19:9; Ezek. 27:7), and some have regarded them as its inventors.

In the wilderness, the Hebrews practised it (Ex. 26:1, 8; 28:4, 39; Lev. 13:47). It is referred to in subsequent times as specially the women's work (2 Kings 23:7; Prov. 31:13, 24). No mention of the loom is found in Scripture, but we read of the "shuttle" (Job 7:6), "the pin" of the beam (Judg. 16:14), "the web" (13, 14), and "the beam" (1 Sam. 17:7; 2 Sam. 21:19). The rendering, "with pining sickness," in Isa. 38:12 (A.V.) should be, as in the Revised Version, "from the loom," or, as in the margin, "from the thrum." We read also of the "warp" and "woof" (Lev. 13:48, 49, 51-53, 58, 59), but the Revised Version margin has, instead of "warp," "woven or knitted stuff."

American Southwest

Weaving a traditional Navajo rug

Textile weaving, using cotton dyed with pigments, was a dominant craft among pre-contact tribes of the American southwest, including various Pueblo peoples, the Zuni, and the Ute tribes. The first Spaniards to visit the region wrote about seeing Navajo blankets. With the introduction of Navajo-Churro sheep, the resulting woolen products have become very well known. By the 1700s the Navajo had begun to import yarn with their favorite color, Bayeta red. Using an upright loom, the Navajos wove blankets and then rugs after the 1880s for trade. Navajo traded for commercial wool, such as Germantown, imported from Pennsylvania. Under the influence of European-American settlers at trading posts, Navajos created new and distinct styles, including "Two Gray Hills" (predominantly black and white, with traditional patterns), "Teec Nos Pos" (colorful, with very extensive patterns), "Ganado" (founded by Don Lorenzo Hubbell), red dominated patterns with black and white, "Crystal" (founded by J. B. Moore), Oriental and Persian styles (almost always with natural dyes), "Wide Ruins," "Chinlee," banded geometric patterns, "Klagetoh," diamond type patterns, "Red Mesa" and bold diamond patterns. Many of these patterns exhibit a fourfold symmetry, which is thought to embody traditional ideas about harmony, or hózhó.

Amazonia

In Native Amazonia, densely woven palm-bast mosquito netting, or tents, were utilized by the Panoans, Tupí, Western Tucano, Yameo, Záparoans, and perhaps by the indigenous peoples of the central Huallaga River basin (Steward 1963:520). Aguaje palm-bast (Mauritia flexuosa, Mauritia minor, or swamp palm) and the frond spears of the Chambira palm (Astrocaryum chambira, A.munbaca, A.tucuma, also known as Cumare or Tucum) have been used for centuries by the Urarina of the Peruvian Amazon to make cordage, net-bags hammocks, and to weave fabric. Among the Urarina, the production of woven palm-fiber goods is imbued with varying degrees of an aesthetic attitude, which draws its authentication from referencing the Urarina’s primordial past. Urarina mythology attests to the centrality of weaving and its role in engendering Urarina society. The post-diluvial creation myth accords women’s weaving knowledge a pivotal role in Urarina social reproduction.[2] Even though palm-fiber cloth is regularly removed from circulation through mortuary rites, Urarina palm-fiber wealth is neither completely inalienable, nor fungible since it is a fundamental medium for the expression of labor and exchange. The circulation of palm-fiber wealth stabilizes a host of social relationships, ranging from marriage and fictive kinship (compadrazco, spiritual compeership) to perpetuating relationships with the deceased.[3]

Islamic world

Hand weaving of Persian carpets and kilims has been an important element of the tribal crafts of many of the subregions of modern day Iran. Examples of carpet types are the Lavar Kerman carpet from Kerman and the Seraband rug from Arak.

An important innovation in weaving that was developed in the Muslim world during the Islamic Golden Age was the introduction of foot pedals to operate a loom. The first such devices appeared in Syria, Iran and Islamic parts of East Africa, where "the operator sat with his feet in a pit below a fairly low-slung loom." By 1177, it was further developed in Al-Andalus, where having the mechanism was "raised higher above the ground on a more substantial frame." This type of loom spread to the Christian parts of Spain and soon became popular all over medieval Europe.[4]

Europe

Dark Age and Medieval Europe

Weighted-warp looms were commonplace in Europe until the development of more advanced looms around the 10th-11th centuries. Especially in colder climates, where a large floor loom would take up too much valuable floor space, the more primitive looms remained in use until the 20th Century to produce "homespun" cloth for individual family needs. The primary material woven in most of Europe was wool, though linen was also common, and imported silk thread was occasionally made into cloth. Both men and women were weavers, though the task often fell to the wife of a farming household. Fabric width was limited to the reach of the weaver, but was sufficient for the tunic-style garments worn in much of Europe at the time. A plain weave or twill was common, since professional weavers with skills to produce better fabrics were rare.

Weaving was a strictly local enterprise until later in the period, when larger weaving operations sprung up in places like Brugges, in Flanders. Within this setting, master weavers could improve their craft and pass skills along to apprentices. As the Middle Ages progressed, significant trade in fine cloth developed, and loom technology improved to allow very thin threads to be woven. Weaver's guilds (and associated craft guilds, like fullers) gained significant political and economic power in some of the bigger weaving cities.

Colonial America

Colonial America was heavily reliant on Great Britain for manufactured goods of all kinds. British policy was to encourage the production of raw materials in colonies. Weaving was not prohibited, but the export of British wool was. As a result many people wove cloth from locally produced fibers in Colonial America.

In Colonial times the colonists mostly used wool, cotton and flax (linen) for weaving, though hemp fiber could be made into serviceable canvas and heavy cloth also. They could get one cotton crop each fall, but until the invention of the cotton gin it was a labor-intensive process to separate the seeds from the cotton fiber. Flax and hemp were harvested in the summer, and the stalks rendered for the long fibers within. Wool could be sheared up to twice yearly, depending on the breed of sheep.

A plain weave was preferred in Colonial times, and the added skill and time required to make more complex weaves kept them from common use in the average household. Sometimes designs were woven into the fabric but most were added after weaving using wood block prints or embroidery.

Industrial Revolution

Before the Industrial Revolution, weaving remained a manual craft, usually undertaken part-time by family craftspeople. Looms might be broad or narrow; broad looms were those too wide for the weaver to pass the shuttle through the shed, so that the weaver needed an assistant (often an apprentice). This ceased to be necessary after John Kay invented the flying shuttle in 1733, which also sped up the process of weaving.

Great Britain

The first attempt to mechanise weaving was the work of Edmund Cartwright from 1785. He built a factory at Doncaster and obtained a series of patents between 1785 and 1792. In 1788, his brother Major John Cartwight built Revolution Mill at Retford (named for the centenary of the Glorious Revolution. In 1791, he licensed his loom to the Grimshaw brothers of Manchester, but their Knott Mill burnt down the following year (possibly a case of arson). Edmund Cartwight was granted a reward of £10,000 by Parliament for his efforts in 1809.[5] However, success in power-weaving also required improvements by others, including H. Horrocks of Stockport. Only during the two decades after about 1805, did power-weaving take hold. Textile manufacture was one of the leading sectors in the British Industrial Revolution, but weaving was a comparatively late sector to be mechanised. The loom became semi- automatic in 1842 with Kenworthy and Bulloughs Lancashire Loom. The various innovations took weaving from a home-based artisan activity (labour intensive and man-powered) to steam driven factories process. A large metal manufacturing industry grew to produce the looms, firms such as Howard & Bullough of Accrington, and Tweedales and Smalley and Platt Brothers. Most cotton weaving took place in weaving sheds, in small towns circling Greater Manchester and worsted weaving in West Yorkshire - men and women with weaving skills emigrated, and took the knowledge to their new homes in New England, in places like Pawtucket and Lowell.

The invention in France of the Jacquard loom, enabled complicated patterned cloths to be woven, by using punched cards to determine which threads of coloured yarn should appear on the upper side of the cloth.

America, 1800-1900

The Jacquard loom attachment was perfected in 1801, and was becoming common in Europe by 1806. It came to the US in the early 1820's, some immigrant weavers bringing jacquard equipment with them, and spread west from New England. At first it was used with traditional human-powered looms. As a practical matter, previous looms were mostly limited to the production of simple geometric patterns. The jacquard allowed individual control of each warp thread, row by row without repeating, so very complex patterns were suddenly feasible. Jacquard woven coverlets (bedspreads) became popular by mid-century, in some cases being custom-woven with the name of the customer embedded in the programmed pattern. Undyed cotton warp was usually combined with dyed wool weft.

Natural dyes were used until just before the American Civil War, when artificial dyes started to come into use.
