Problems solved by technology

[0003] As we all know, silk fabrics are soft and smooth, soft and light to the touch, colorful and cool to wear, and are mainly used as summer shirts, pajamas, dress fabrics and headscarves, etc., and are very popular textiles; but silk products are very expensive and The output is limited. In order to meet the needs of consumers, imitation silk fabrics came into being. The weaving raw materials used for imitation silk fabrics are filaments in chemical fibers: nylon, polyester, viscose fiber superfine filaments and special-shaped filaments

Abstract

The invention discloses a special silk yarn highly imitating regenerated cellulose staple fiber. The yarn is designed as regenerated staple fiber super-twisted yarn, and the twist coefficient of the yarn is 1.8 to 2.5 times that of ordinary twist yarn. And through the pre-twisting production process, the yarn with the concentric conical helix as the main space structure is formed. The present invention also provides a fabric woven by using the yarn of the present invention, through the matching of the ratio of warp and weft yarns and the type of yarn, and matching processes such as warping, sizing, drafting and weaving in batches. The high imitation silk (crepe) fabric produced has a lifelike fabric style, elegant crepe on the crepe surface, moisture absorption and air permeability better than chemical fiber filament imitation silk crepe fabric, and meets people's new fashion needs for summer clothing.

Description

technical field [0001] The present invention relates to a special yarn for regenerated cellulose staple fiber with high imitation silk (crepe) and fabrics produced from the yarn; The invention relates to a production method of a yarn and a fabric, belonging to the field of textile textiles. Background technique [0002] Imitation silk fabrics are relative to real silk fabrics. Generally, the weaving raw materials used in real silk fabrics refer to silk, including mulberry silk, tussah silk, castor silk, cassava silk, etc.; the weaving raw materials used in imitation silk fabrics are filaments in chemical fibers. , including nylon, polyester, viscose superfine silk and special-shaped silk; silk fabrics are divided into 14 categories according to fabric structure, warp and weft combination, processing technology and silk surface performance shape; among them, silk crepe is a very important one. The main category is to use plain weave or other weaves, warp or weft enhanced twi...
