The fabrication of yarn (thread) from either discontinuous natural fibers or bulk synthetic polymeric material. In a textile context the term spinning is applied to two different processes leading to the yarns used to make threads, cords, ropes, or woven or knitted textile products.

Natural fibers, such as wool, cotton, or linen, are generally found as short, entangled filaments. Their conversion into yarn is referred to as spinning. After a carding operation on the raw material to disentangle the short filaments, the filaments are drawn (drafted) to promote alignment in an overlapping pattern and then twisted to form, by mechanical interlocking of the discontinuous filaments, a resistant continuous yarn. See also Cotton; Wool.

The term spinning is also used for the production of monofilaments from synthetic polymers—for example, polyamides or nylons, polyesters, and acrylics—or modified natural polymers, such as cellulose-rayon. Generally the monofilaments are stretched (drawn) to increase their strength by promoting molecular orientation and are wound as yarn which can be used directly for threads, cords, or ropes. Such yarn, however, is often cut into relatively short lengths (staple) and reformed by a process similar to that used for natural fibers into a yarn more suitable, in terms of appearance and feel, for making certain textile products. See also Manufactured fiber; Natural fiber.

spinning, the drawing out, twisting, and winding of fibers into a continuous thread or yarn. From antiquity until the Industrial Revolution, spinning was a household industry. The roughly carded fiber was at first held in one hand and drawn out and twisted by the other hand. The earliest tools were the distaff, a stick on which the fiber was wrapped, and the spindle, a shorter, tapering stick notched at one end and weighted by the wharve or whorl (a disk of stone or clay). The spindle was twirled to twist the thread, which was then wound on it. With these simple tools were spun extremely fine yarns. In India the delicate threads for the famed Dacca muslin were produced by revolving needle-thin pieces of bamboo in a coconut shell. The primitive Gurkha wheel was used to spin coarse yarns. In Europe from the 14th to the 16th cent. the distaff and spindle were gradually superseded by the spinning wheel. It consisted of a spindle set in a frame and revolved by a driving belt passing over a wheel. The great, or wool, wheel, revolving the spindle directly, then by a pulley, twisted the thread; it was then stopped and revolved in the opposite direction to back off the spun yarn, which was then wound on the spindle. The flax, or Saxony, wheel—a more elaborate mechanism operated by a treadle—drew, twisted, and wound the yarn with a continuous motion suited to flax, wool, or cotton. In England improvements of the loom in the 18th cent., increasing the demand for yarn, stimulated inventions that revolutionized spinning. John Wyatt suggested the use of rollers to attenuate the yarn, a process patented in 1738 by his partner, Lewis Paul. James Hargreaves invented c.1765 the spinning jenny, a frame capable of spinning from 8 to 11 threads at once. The softly twisted yarns were not suitable for use as warp threads, but in 1769, Richard Arkwright brought out his frame, which by means of successive pairs of rollers, each revolving faster than the preceding pair, attenuated the yarn and twisted and wound it on bobbins in a continuous action. Operated at first by horse or mule power, later by water power, and still later by steam, spinning rapidly became a factory enterprise. In 1779, Samuel Crompton, combining the best features of the jenny and of Arkwright's frame, invented the mule spinning frame, forerunner of the modern self-acting mule. Because of its intermittent action, the mule is used for fine or delicate yarns. For the mass production of coarser yarns, the ring frame, an elaboration of Arkwright's machine, invented by John Thorp c.1828, draws, twists, and winds the thread in one rapid, continuous operation.


 
Dream Symbol: Spinning

Spinning in a dream can be represented by spinning of thread on a spinning wheel to create fabric, or a child spinning a top or even themselves in circles. It may be that the dreamer is about to embark on some sort of industrious task. It also suggests conjuring up an "old yarn," story, or tale.

The Spinner by William-Adolphe Bouguereau shows a woman hand-spinning using a drop spindle. Fibers to be spun are bound to a distaff held in her left hand.

Spinning is an ancient textile art in which plant, animal or synthetic fibers are twisted together to form yarn. For thousands of years, fiber was spun by hand using simple tools, the spindle and distaff. Only in the High Middle Ages did the spinning wheel increase the output of individual spinners, and mass-production only arose in the 18th century with the beginnings of the Industrial Revolution. Hand-spinning remains a popular handicraft.

Characteristics of spun yarn vary based on the material used, fiber length and alignment, quantity of fiber used, and degree of twist.

The origins of spinning fiber to make string or yarn are lost in time, but archaeological evidence in the form of representation of string skirts has been dated to the Upper Paleolithic era, some 20,000 years ago.[1] In the most primitive type of spinning, tufts of animal hair or plant fiber are rolled down the thigh with the hand, and additional tufts are added as needed until the desired length of spun fiber is achieved. Later, the fiber is fastened to a stone which is twirled round until the yarn is sufficiently twisted, whereupon it is wound upon the stone and the process repeated over and over.

The next method of twisting yarn is with the spindle, a straight stick eight to twelve inches long on which the thread is wound after twisting. At first the stick had a cleft or split in the top in which the thread was fixed. Later, a hook of bone was added to the upper end. The bunch of wool or plant fibers is held in the left hand. With the right hand the fibers are drawn out several inches and the end fastened securely in the slit or hook on the top of the spindle. A whirling motion is given to the spindle on the thigh or any convenient part of the body. The spindle is then dropped, twisting the yarn, which is wound on to the upper part of the spindle. Another bunch of fibers is drawn out, the spindle is given another twirl, the yarn is wound on the spindle, and so on.[2]

The distaff was used for holding the bunch of wool, flax, or other fibers. It was a short stick on one end of which was loosely wound the raw material. The other end of the distaff was held in the hand, under the arm or thrust in the girdle of the spinner. When held thus, one hand was left free for drawing out the fibers.[2]

A spindle containing a quantity of yarn rotates more easily, steadily, and continues longer than an empty one; hence, the next improvement was the addition of a weight called a spindle whorl at the bottom of the spindle. These whorls are discs of wood, stone, clay, or metal with a hole in the center for the spindle, which keep the spindle steady and promote its rotation. Spindle whorls appeared in the Neolithic era.[2].[3]

Industrial spinning

Modern powered spinning, originally done by water or steam power but now done by electricity, is vastly faster than hand-spinning.

The spinning jenny, a multi-spool spinning wheel invented circa 1764 by James Hargreaves, dramatically reduced the amount of work needed to produce yarn, with a single worker able to work eight or more spools at once. At roughly the same time, Richard Arkwright and a team of craftsmen developed the spinning frame, which produced a stronger thread than the spinning jenny. Too large to be operated by hand, a spinning frame powered by a waterwheel became the water frame.

In 1779, Samuel Crompton combined elements of the spinning jenny and water frame to create the spinning mule. This produced a stronger thread, and was suitable for mechanisation on a grand scale.

In the 20th century, new techniques including Open End spinning or rotor spinning were invented to produce yarns at rates in excess of 40 meters per second.

Characteristics of spun yarns

Materials

Yarn can be, and is, spun from a wide variety of materials, including natural fibers such as animal, plant, and mineral fibers, and synthetic fibers. It was probably first made from plant fibers, but animal fibers soon followed.

Twist and ply

S-twist and Z-twist yarns

The direction in which the yarn is spun is called twist. Yarns are characterized as S-twist or Z-twist according to the direction of spinning (see diagram). Tightness of twist is measured in TPI (twists per inch or turns per inch)[4]

Two or more spun yarns may be twisted together or plied to form a thicker yarn. Generally, handspun single plies are spun with a Z-twist, and plying is done with an S-twist.[5]

Plying methods

Yarns can be made of two, three, four, or more plies, or may be used as singles without plying. Two-ply yarn can also be plied from both ends of one long strand of singles using Andean plying, in which the single is first wound around one hand in a specific manner that allows unwinding both ends at once without tangling. Navajo plying is another method of producing a three-ply yarn, in which one strand of singles is looped around itself in a manner similar to crochet and the resulting three parallel strands twisted together. This method is often used to keep colors together on singles dyed in sequential colors. Cabled yarns are usually four-ply yarns made by plying two strands of two-ply yarn together in the direction opposite to the plying direction for the two-ply yarns.

Contemporary hand spinning

Hand-spinning is still an important skill in many traditional societies. Hobby or small scale artisan spinners spin their own yarn to control specific yarn qualities and produce yarn that is not widely available commercially.Sometimes these yarns are made available to non-spinners online and in local yarn stores. Handspinners also may spin for self-sufficiency, a sense of accomplishment, or a sense of connection to history and the land. In addition, they may take up spinning for its meditative qualities.

Within the recent past, many new spinners have joined into this ancient process, innovating the craft and creating new techniques. From using many new applications of dyeing before spinning, to mixing in random elements (Christmas Garland, eccentric beads, money, etc.) that would not be in a traditional yarn, to creating new techniques like coiling[6], this craft is constantly evolving and shifting.

To make various yarns, besides adding random elements, spinners can vary all the same things as in a machined yarn, i.e., the fiber, the preparation, the color, the spinning technique, the direction of the twist, etc. A common misconception is yarn spun from rolags may not be as strong, but the strength of a yarn is actually based on the length of hair fiber and the degree of twist. When working with shorter hairs, such as llama or angora rabbit, the spinner may choose to integrate longer fibers, such as mohair, to prevent yarn breakage. Yarns made of shorter fibers are also given more twist than yarns of longer fibers, and are generally spun with the short draw technique.

The fiber can be dyed at any time, but is often dyed before carding or after the yarn has been spun.

Wool may be spun before or after washing, although excessive amounts of lanolin may make spinning difficult, especially when using a drop-spindle. Careless washing may cause felting. When done prior to spinning, this often leads to unusable wool fiber. In washing wool the key thing to avoid is too much agitation and fast temperature changes from hot to cold. Generally, washing is done lock by lock in warm water with dish-soap.

Techniques

A handspinner using the short draw technique to spin wool.

A tightly spun wool yarn with no air in it is called worsted. It is hand spun from a roving or combed top, and the fibers all lie in the same direction as the yarn. A woolen yarn, in contrast, is hand spun from a rolag, where the fibers are not as strictly aligned to the yarn created. The woolen yarn, thus, captures much more air, and makes for a softer and generally bulkier yarn. There are two main techniques to create these different yarns: short draw creates worsted yarns, and long draw creates woolen yarns. Often a spinner will spin using a combination of both techniques and thus make a semi-worsted yarn.[7]

Short draw spinning is used to create worsted yarns. It is spun from combed roving, sliver or wool top. The spinner keeps his/her hands very close to each other. The fibers are held, fanned out, in one hand, and the other hand pulls a small number from the mass. The twist is kept between the second hand and the wheel. There is never any twist between the two hands.

Long draw is spun from a carded rolag. The rolag is spun without much stretching of the fibers from the cylindrical configuration. This is done by allowing twist into a short section of the rolag, and then pulling back, without letting the rolag change position in your hands, until the yarn is the desired thickness. The twist will concentrate in the thinnest part of the roving; thus, when the yarn is pulled, the thicker sections with less twist will tend to thin out. Once the yarn is the desired thickness, enough twist is added to make the yarn strong. Then the yarn is wound onto the bobbin, and the process starts again.

Spinning in the grease

Handspinners are split, when spinning wool, as to whether it is better to spin it 'in the grease' (with lanolin still in) or after it has been washed. More traditional spinners are more willing to spin in the grease, as it is less work to wash the wool after it is in yarn form. Spinners who spin very fine yarn may also prefer to spin in the grease as it can allow them to spin finer yarns with more ease. Spinning in the grease covers the spinner's hands in lanolin and, thus, softens the spinner's hands.

Spinning in the grease only works really well if the fleece is newly sheared. After several months, the lanolin becomes sticky, which makes it harder to spin using the short draw technique, and almost impossible to spin using the long draw technique. In general, spinners using the long draw technique do not spin in the grease.

Spinners who don't spin in the grease generally buy their fibers pre-washed and carded, in the form of tow or roving. This means less work for the spinner, as they do not have to wash the lanolin out. It also means that one can spin predyed fiber, or blends of fibers, which are very hard to create when the wool is still in the grease. As machine carders cannot card wool in the grease, pre-carded yarn generally isn't spun in the grease. Some spinners, however, use spray-on lanolin-like products to get the same feel of spinning in the grease with this carded fiber.
