FIBER STRUCTURE OF WHOLE AROMATIC POLYAMIDE HAVING IMPROVED LIGHT FASTNESS

摘要

PROBLEM TO BE SOLVED: To provide a fiber structure of a whole aromatic polyamide having extremely improved light fastness even if the fiber structure is dyed in any color. SOLUTION: This fiber structure having a surfactant and an improver of light resistance fixed thereon has class 3-4 light fastness or the fastness better than that, when irradiating the whole aromatic polyamide fiber structure with light at 63 deg.C for 20 hr by a fadeometer.
