Title:
MATTE HIGH-STRENGTH, LOW-STRETCH VISCOSE FIBER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/188274
Kind Code:
A1
Abstract:
The present invention relates to the technical field of textile fiber processing. Disclosed is a matte high-strength, low-stretch viscose fiber. he viscose fiber is produced from a pulp raw material that sequentially undergoes impregnation, grinding, pressing and crushing, rubbing, degradation, xanthation, dissolution, filtration, defoaming, aging, spinning and drafting, and aftertreatment. The viscose fiber of the present invention has the following technical indicators: dry tensile strength ≥ 3.10 cN/dtex, wet tensile strength ≥ 1.60 cN/dtex, strength required to produce 5% elongation in a wet state ≥ 0.55 cN/dtex, dry breaking elongation 11.0-19.0%, wet breaking elongation 16.0-21.0%, radial water swelling capacity 22-26%, and matting agent content 0.8-5%. The viscose fiber of the present invention is a novel viscose fiber and has lower production costs compared with an existing modal, thus providing great economic and social benefits.
