Problems solved by technology

[0005] However, the bending and torsional rigidity of hemp fiber is large, the fiber is not easy to cohere, the length unevenness is high, the fiber end is easy to pop out of the yarn body, the hairiness is much, hard and long
Therefore, pure hemp yarn is hard, brittle and straight, and has defects such as low single strength and many knots, which makes it difficult for knitting and weaving to bend and form loops.

Abstract

The invention discloses a China-hemp Dai fabric which is formed by interweaving warps and wefts through a jacguard; the warps are blended yarns of China-hemp and lustrous rayons; the weight ratio of the China-hemp to lustrous rayons in the warps is 30-50:50-70; the count of the warps are 60-45s and the twist coefficient of the warps is 450-490; the wefts are blended yarns of Porel fibers and Dacron; the weight ratio of the Porel fibers to Dacron in the wefts is 20-35:65-80, the denier of the wefts is 100-200D and the twist coefficient is 370-390. The China-hemp Dai fabric is bright-colored and soft in hand feeling and has the self-temperature and humidity adjusting, controlling and balancing function and the strength and performance of the China-hemp Dai fabric also meet the industrial production demands.

Description

technical field [0001] The invention relates to a textile fabric, in particular to a Dai cloth fabric of hemp jacquard and a production process thereof. Background technique [0002] Now many national costume fabrics on the market, especially the national costume fabrics of the Dai people are basically jacquard fabrics with gorgeous colors and complex patterns. Mainly polyester fabric. Fabrics other than polyester are only handmade and cannot be mass-produced. The disadvantages of the existing Dai clothing fabrics are non-absorbent, airtight, and poor comfort under local natural conditions, and because there are certain problems in the jacquard part of the Dai cloth, it causes serious itching when worn. [0003] The "hemp fibers" in daily life are mainly daily necessities such as "hemp ropes" and "sacks", which give people the impression that they are rough and stiff in appearance, dull in color, wear-resistant, and uncomfortable to skin. With the development of science a...
