Title:
POLYAMIDE SPUN-DYED YARN HAVING EXCELLENT STAIN RESISTANCE
Document Type and Number:
Japanese Patent JP02133613
Kind Code:
A
Abstract:
PURPOSE: To obtain the subject spun-dyed yarn hardly stained with acidic dust material and thus undyed yarn after mixing weaving with the aimed yarn is able to be dyed without anxiety of staining or dyeing of the aimed yarn containing cation-soluble polymer as constituting polyamide in multifilament.
CONSTITUTION: The aimed spun-dyed yarn is composed of cation-soluble polyamide multifilament. Besides, preferably amino group concentration of terminal group of said polyamide is ≤10g equiv./106g and sulfonic acid salt is contained in the other terminal group. Furthermore, 100-700ppm copper compound (preferably cuprous halide) is preferably added.
