Polyamide fibers having reduced amino end groups, light-dyed and stain resistant polyamide fibers made therefrom, and method of preparation.

摘要

Polyamide fibers reacted with an epsilon-caprolactone compound have a reduced affinity for acid dyes. The fiber finds particular application in preparing two-tone yarn. Additionally, the polyamide fibers can be treated with one or more stainblockers to produce a stain resistant polyamide fiber having excellent resistance to acid dye colorants.
