An assemblage of fibers that are twisted or laid together so as to form a continuous strand that can be made into a textile fabric. So a yarn is a strand of natural or man-made fibers or filaments that have been twisted or grouped together for use in weaving, knitting, or other methods of constructing textile fabrics. The type of yarn to be manufactured will depend on the fibers selected; the texture, or hand, of the fabric to be made; and qualities such as warmth, resiliency, softness, and durability required in the fabric's end use.
