Spinning (textiles)

Spinning is a major industry. It is part of the textile manufacturing process where three types of fibre are converted into yarn, then fabric, then textiles. The textiles are then fabricated into clothes or other artifacts. There are three industrial processes available to spin yarn, and a handicraft community who use hand spinning techniques. Spinning is the twisting together of drawn out strands of fibres to form yarn, though it is colloquially used to describe the process of drawing out, inserting the twist, and winding onto bobbins.[1]


Types of fibre

Artificial fibres are made by extruding a polymer through a spinneret into a medium where it hardens. Wet spinning (rayon) uses a coagulating medium. In dry spinning (acetate and triacetate), the polymer is contained in a solvent that evaporates in the heated exit chamber. In melt spinning (nylons and polyesters) the extruded polymer is cooled in gas or air and sets.[2]. All these fibres will be of great length, often kilometers long.

Natural fibres are either from animals (sheep, goat, rabbit, silk-worm), mineral (asbestos), or from plants (cotton, flax, sisal). These vegetable fibres can come from the seed (cotton), the stem (known as bast fibres: flax, hemp, jute) or the leaf (sisal).[3] Without exception, many processes are needed before a clean even staple is obtained- each with a specific name. With the exception of silk, each of these fibres is short, being only centimetres in length, and each has a rough surface that enables it to bond with similar staples.[4]

Artificial fibres can be processed as long fibres or batched and cut so they can be processed like a natural fibre.


Most spinning is done using break or open-end spinning, this is a technique where the staples are blown by air into a rotating drum, where they attach themselves to the tail of formed yarn that is continually being drawn out of the chamber. Other methods of break spinning use needles and electrostatic forces.[5] This method has replaced the older methods of ring and mule spinning. It is also easily adapted for artificial fibres.

The spinning machine takes the roving, thins it and twists it, creating yarn which it winds onto a bobbin.[6]
In mule spinning the roving is pulled off a bobbin and fed through rollers, which are feeding at several different speeds.This thins the roving at a consistent rate. If the roving was not a consistent size, then this step could cause a break in the yarn, or could jam the machine. The yarn is twisted through the spinning of the bobbin as the carriage moves out, and is rolled onto a cop as the carriage returns. Mule spinning produces a finer thread than the less skilled ring spinning.[7]
  • The mule was an intermittent process, as the frame advanced and returned a distance of 5ft.It was the descendant of a 1779 Crompton device. It produces a softer, less twisted thread that was favoured for fines and for weft.
  • The ring was a descendant of the Arkwright water frame of 1769. It was a continuous process, the yarn was coarser, had a greater twist and was stronger so was suited to be warp. Ring spinning is slow due to the distance the thread must pass around the ring, and similar methods have improved on this; such as flyer and bobbin and cap spinning.
Sewing thread, was made of several threads twisted together, or doubled.

The pre-industrial techniques of hand spinning with spindle or spinning wheel continue to be practiced as a handicraft or hobby, and enable wool or unusual vegetable and animal staples to be creatively used.

  • Checking
This is the process where each of the bobbins is rewound to give a tighter bobbin.
  • Folding and twisting
Plying is done by pulling yarn from two or more bobbins and twisting it together, in the opposite direction from that in which it was spun. Depending on the weight desired, the yarn may or may not be plied, and the number of strands twisted together varies.[8]

History and economics

Hand-spinning was a cottage industry in medieval Europe, where the wool spinners (often women and children) would provide enough yarn to service the needs of the men who operated the loom. This would occur in districts favourable to sheep husbandry. The introduction of the flying shuttle upset this balance. The subsequent invention of the spinning jenny water frame redressed the balance but required water power to operate the machinery, and the industry relocated to West Yorkshire where this was available. The nascent cotton industry was located on wetter side of the same hills. The British government was very protective of this technology, restricting its export. By the aftermath of World War I the colonies where the cotton was grown started to purchase and manufacture significant quantities of cotton spinning machinery. The next breakthrough was with the move over to break or open-end spinning, and then the adoption of artificial fibres. By then most production had moved to India and China.
