Carding in the context of Anthidium manicatum

Sir Richard Arkwright (23 December 1732 – 3 August 1792) was an English inventor and a leading entrepreneur during the early Industrial Revolution. He is credited as the driving force behind the development of the spinning frame, known as the water frame after it was adapted to use water power; and he patented a rotary carding engine to convert raw cotton to 'cotton lap' prior to spinning. He was the first to develop factories housing both mechanised carding and spinning operations.

Arkwright's achievement was to combine power, machinery, semi-skilled labour and the new raw material of cotton to create mass-produced yarn. His organisational skills earned him the accolade "father of the modern industrial factory system," notably through the methods developed in his mill at Cromford, Derbyshire (now preserved as part of the Derwent Valley Mills World Heritage Site).

Woolen (American English) or woollen (Commonwealth English) is a type of yarn made from carded wool. Woolen yarn is soft, light, stretchy, and full of air. It is thus a good insulator, and makes a good knitting yarn. Woolen yarn is in contrast to worsted yarn, in which the fibers are combed to lie parallel rather than carded, producing a hard, strong yarn.

Worsted (/ˈwɜːrstɪd/ or /ˈwʊstɪd/) is a high-quality type of wool yarn, the fabric made from this yarn, and a yarn weight category. The name derives from Worstead (from Old English Wurðestede, "enclosure place"), a village in the English county of Norfolk. That village, together with North Walsham and Aylsham, formed a manufacturing centre for yarn and cloth in the 12th century, when pasture enclosure and liming rendered the East Anglian soil too rich for the older agrarian sheep breeds. In the same period, many weavers from the County of Flanders moved to Norfolk. "Worsted" yarns/fabrics are distinct from woollens (though both are made from sheep's wool): the former is considered stronger, finer, smoother, and harder than the latter.

Worsted was made from the long-staple pasture wool from sheep breeds such as Teeswaters, Old Leicester Longwool and Romney Marsh. Pasture wool was not carded; instead it was washed, gilled and combed (using heated long-tooth metal combs), oiled and finally spun. When woven, worsteds were scoured but not fulled.

Combing is a method for preparing carded fibre for spinning. Combing aligns fibers in parallel before spinning to produce a smoother, stronger, and more lustrous yarn. The process of combing is accompanied by gilling, a process of evening out carded or combed top making it suitable for spinning. Combing separates out short fibres by means of a rotating ring or rectilinear row of steel pins. The fibres in the 'top' it produces have been straightened and lie parallel to each other. When combing wool, the discarded short fibres are called noils, and are ground up into shoddy.

In general, there are two main systems of preparing fibre for yarn: the worsted system and the woollen system. The worsted system is defined by the removal of short fibres by combing and top preparation by gilling. In the woollen system, short fibres are retained, and it may or may not involve combing.
