ACRYLIC CONJUGATE FIBER AND NONWOVEN FABRIC CONTAINING THE SAME, AND METHOD FOR PRODUCING THE ACRYLIC CONJUGATE FIBER

摘要

PROBLEM TO BE SOLVED: To provide an acrylic conjugate fiber having high liquid-absorbing capacity and high solvent resistance through acquiring large specific surface area by splitting/fibrillation even with low energy, and to provide a nonwoven fabric containing the acrylic conjugate fibers. SOLUTION: The acrylic conjugate fiber with an apparent fineness ratio of 1.5-3.0 is composed of 40-85 mass% of an acrylonitrile-based polymer containing 50 mass% or more of acrylonitrile and 60-15 mass% of a cellulosic polymer. The acrylic conjugate fiber acquires large specific surface area through splitting/fibrillation even with low energy, therefore being suitable for use in nonwoven fabrics. The nonwoven fabrics using the conjugate fibers have high liquid-absorbing capacity and high solvent resistance. COPYRIGHT: (C)2007,JPO&INPIT
