Low shrinkage, uncrimped short-cut fibers for use in wet laid non-woven products and method for making same

Abstract

Low shrinkage, short-cut polyethylene terephthalate fiber exhibiting dispersibility suitable for incorporation into wet laid non-woven products is produced through the use of steam-annealing. The preferred fibers exhibit a hot air shrinkage value of less than about 10 percent, have a length of less than 3 inches, and a dispersion index of less than 5.
