USE OF A POROUS ACRYLIC FIBER AND FABRIC COMPRISING THE SAME, AND METHOD OF PRODUCING THE SAME

摘要

Porous acrylic fibers produced by a method comprising subjecting a spinning dope containing 0.3 to 20 parts by weight of poly(vinyl acetate) relative to 100 parts of an acrylic copolymer to a wet spinning to give fibers, crimping and cutting the fibers, subjecting the resultant fibers to a treatment by hot water at 90 to 100 DEG C for 30 to 120 minutes or by saturated steam at 90 to 130 DEG C for 10 to 90 minutes to thereby form porous fibers; and a pile fabric having pile portions which comprise the porous fibers in an amount of 3 wt% or more, and, in the pile fabric, respective single fibers are visible being separate and emphasized, and thus the pile fabric has an appearance being highly decorative and excellent in design characteristics.
