Title:
WATER-ABSORBING POLYAMIDE FIBER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH07189119
Kind Code:
A
Abstract:
PURPOSE: To obtain a new polyamide fiber having light weight and excellent water-absorbing performance, water-retaining performance and water-releasing performance and free from slimy feeling.
CONSTITUTION: This polyamide fiber is characterized in that the single fiber constituting the polyamide fiber is a dense agglomerate of fibrils oriented nearly parallel to the fiber axis. It can be produced by subjecting a fiber obtained by the melt-spinning of a blend polymer composed of 70-50wt.% of a polyamide and 30-50wt.% of a polyester obtained by the copolymerization of a polyethylene terephthalate with 10-30wt.% of a polyethylene glycol, thereby dissolving and removing the copolymerized polyester.
