Description
The combs used have long metal teeth, and only barely resemble the comb used on hair. However, they are used in a similar fashion with one comb holding the fibre while the other is moved through, slowly transferring the fibre to the moving comb.
Combing the fibres removes the short fibres and arranges the fibre in a flat bundle, with all the fibres going the same direction. This preparation is commonly used to spin a worsted yarn. Woollen yarns cannot be spun from fibre prepared with combs, instead the fibre must be carded. Cotton is combed when it is to be used for quality fabric with high thread counts.
In general, combing is done with fibres that are longer, and carding with fibres of a shorter length. Worsted yarns pass first through a gilling machine instead of a carder, which starts the combing process, and then through a comber.

Famous quotes containing the word description:
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
