1. A fabric in which the weft consists of single fibres of horsehair, obtained from tails and manes and woven on a special loom which is capable of inserting picks of the discontinuous fibres. The fabric width is governed by the length of available horsehair and normally varies between 47cm and 76cm. The woven structure, which usually has a cotton warp, varies according to the enduse, e.g., interlinings, furnishing fabrics, sieve and press cloths, and the horse hair may be dyed. 2. A fabric produced from yams in which horsehair is mixed with cotton, polyester, linen or other fibres to make it strong and inflexible. Used in upholstery and also as a chest canvas in tailoring.
Haircloth is a stiff, unsupple fabric typically made from horsehair and/or from the wooly hair of a camel. Although horsehair generally refers to the hair of a horse's mane or tail, haircloth itself is sometimes called horsehair. Horse or camel hair woven into haircloth may be fashioned into clothing or upholstery.
