LUMINOUS CONJUGATED FIBER HAVING THREE-LAYER CROSS-SECTION STRUCTURE

摘要

PURPOSE: Provided is luminous conjugated fiber which is characterized by having three-layer cross-section structure, having excellent strength and brightness, minimizing abrasion of machine on producing and having moderate prices because luminous fluorescent agent is in a middle layer of fiber. CONSTITUTION: The luminous conjugated fiber is comprised of an outer layer(1), a middle layer(2) and an inner layer(3). The outer layer(1) is comprised of transparent fiber forming polymer having under 20μm of thickness. The middle layer(2) is comprised of fiber forming polymer containing 10-50wt.% of the luminous fluorescent agent. The inner layer(3) is comprised of fiber forming polymer. The middle layer(2) is bisected. A space(α) of theirs is 1-20μm.
