Problems solved by technology

But at present, there are very few varieties of viscose filaments with special-shaped cross-sections, which are limited to flat yarns and three-lobed cross-section yarns, which are far from meeting market demand. The development of rubber fiber has positive promotion significance, and its market prospect is also very optimistic

Abstract

The invention relates to an abnormal section mucilage glue filament and the method to manufacture, and the thread spurting component that is used to solve the manufacture problem of crisscross mucilage glue filament. It belongs to weave technology field. The process is that: there are four ramifications on the section of the mucilage glue, which are crisscrossed, and the length-width ratio of the ramification is from 3 to 10:1. The invention has crisscrossed section, thus its wet-transmitting capability, sweating capability, and gas permeability are better than that of flat silk and trilobite silk. It is the ideal material for comfortable and functionality textile.

Description

technical field [0001] The invention relates to a new textile raw material, a preparation method of the raw material and a special mold used for producing the raw material, belonging to the technical field of textiles. Background technique: [0002] Viscose filament is a high-quality textile raw material. The textiles made of it have the characteristics of good moisture absorption, breathability, softness, smoothness, drape, bright luster, excellent dyeability and antistatic properties. These characteristics are many Synthetic fibers can not be compared. With the continuous improvement of modern people's health concepts and fashion vision, consumers have gradually increased their requirements for fashion, comfort and health care functions of clothing fabrics, and the existing product structure is far from meeting the needs of the market. The development of viscose Differentiated and functional varieties of filaments, and the diversification of products are the development d...
