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 a rotatable, small diameter tube coated with abrasive particles. Abrasive particles are preferably rounded (nonfaceted) tungsten carbide particles. The tube can be rotated at a slow speed and the surface speed of the tube may be a fixed percentage of the textile fabric web speed. The contact angle of the textile fabric web with the tube is between one (1) and one hundred and twenty (120) degrees. The average pressure between the textile fabric web and the tube should exceed two (2) pounds per square inch (p.s.i.)./! |
