DISPERSION OF SYNTHETIC-FIBER FOR WET-LAY NONWOVENS

Successful development and production of wet-lay nonwovens is linked c losely to the knowledge, understanding, and proper use of synthetic fi bers. Some factors related to the characteristic dispersion properties of synthetic fibers are presented These include effects of the generi c fiber type, fiber size, aspect ratio, fiber end-out condition, surfa ce characteristics, and fiber yarn. Some methods of dispersion evaluat ion also are noted.
