Your cotton shirt was beaten, combed, flamed and twisted before anyone wove it
A cotton T-shirt begins as fluff clinging to seeds inside a pod, each fibre about 2.5 centimetres long. Turning that fuzz into smooth fabric takes a surprisingly violent sequence: machines strip it, batter it with steel bars, comb it into ropes, twist it tight and sometimes whip it through gas flames.
Cotton accounts for 90 percent of the natural fibre used by the textile trade, and in 2007 the world harvested 25 million tons from more than 50 countries. It thrives where summers are long, hot, sunny and dry. Finer Indian cotton has a short staple suited only to hand work, whereas American cotton, with its longer fibres, suits mechanised mills. After harvest a gin separates seeds and dirt from the lint, and only a third of the crop ends up usable. The lint is pressed into bales weighing almost 220 kilograms.
At the mill a spiked opener tears the bales apart. Scutching then feeds the cotton between rollers and pounds it with fast-spinning beater bars so seeds drop away; the first such machine appeared in 1797 and was standard by 1816 after catching on in Manchester. Carding lines the fibres up into a loose rope about half an inch thick called a sliver. Several slivers are merged to even out thin and thick patches, and optional combing removes short fibres for a stronger yarn.
Spinning thins and twists the result. The mule, descended from a 1779 device by Samuel Crompton, made soft, lightly twisted thread for fine cloth, while the ring, heir to Arkwright's water frame of 1769, produced tougher yarn for warp. Both have largely given way to open-end spinning, where air blows fibres into a whirling drum. Premium yarns for poplins and gabardines are gassed, rushed through flames to singe off stray fuzz.
Only then comes weaving. Starch stiffens the lengthwise warp so it survives the loom while a shuttle carries the crosswise weft back and forth. In the mid-nineteenth century a weaver typically tended four machines; a skilled hand in 1925 could manage six Lancashire looms.
