ABSTRACT:
A method and apparatus for loosening, cutting, and abrading a web of textile fabric having spun yarns containing wrapper fibers. The textile fabric web is directed under high tension around pairs of rotatable, small diameter tubes coated with abrasive particles. Abrasive particles are preferably rounded (nonfaceted) tungsten carbide particles. The tubes (rolls) are rotated at differing speeds in relation to the fabric web speed through the apparatus. Preferably, the first, regressive roll rotates at a speed slower than the web speed and the second, progressive roll rotates at a faster such speed. Such a process and apparatus provide improved conditioning and napping of a fabric web as well as a quicker, more efficient method of performing such fabric treatment.
