Shearing (textiles)

Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height.

Shearman's job was to nap the cloth manually, using teasels and shears to trim the pile.

During the early 17th century, two shearmen spent two weeks dry shearing three broadcloths.

[10][11] Other than imparting an aesthetic finish, shearing was also used to cut certain deformations, unwanted surface defects such as protruding yarns.

[1] In the case of polyester blends, a shearing machine is also useful for removing surface beads or naps of dyed fibers.
