Piled Nap
Since the 15th century, the term nap generally refers to a special pile given to the cloth. The term pile refers to raised fibres that are there on purpose, rather than as a by product of producing the cloth. In this case, the nap is woven into the cloth, often by weaving loops into the fabric, which can then be cut or left intact. Carpets, rugs, velvet, velour, and velveteen, are made by interlacing a secondary yarn through woven cloth, creating a nap or pile.
