Anotations

Scope note:

Mechanized devices, typically comprising a series of revolving rollers covered with steel napper wires or teasels, designed to raise the naps or pile fibers on a fabric's surface to create a velvety, soft finish. As fabric is passed through the device's cylinders, its loose surface fibers come into contact with the napper wires or teasels; these sharp mechanisms lift the fibers from the fabric's weft yarns to the its surface to form naps. This process, which increases the fabric's warmth, is often applied to woollens, cottons, spun silks, and spun rayons, amongst other knitted or woven materials.
