A kind of preparation method of ramie wool elastic fabric

Abstract

The invention discloses a method for preparing a ramie wool elastic fabric. The preparation steps are as follows: 1) warp yarn: worsted, yarn count Nm 50 / 2-60 / 2; weft yarn: worsted yarn, yarn count Ne 50 / 2 and 32 / 1+spandex; the warp and weft yarns are woven with 2 / 2 weave and the total tightness of 100‑105 to obtain gray cloth; 2) Finishing: gray cloth shaping → singeing → continuous cooking → washing shrinkage → double cooking → drying → Intermediate inspection → familiar repair → brushing → brushing → washing → drying → shaping → shearing → softening → pot steaming to get the finished product. White ramie is added in the last needle comb of combing, and the slub effect of the finished fabric is achieved by taking advantage of the fact that the hemp strips are not easy to mix evenly; the spinning section only passes through the last needle comb and a roving; the finishing is done by washing. Improve the dimensional stability of the fabric; the brushing process makes the fabric surface slightly fluffy, which increases the warmth and softness of the fabric, and finally makes this product have the advantages of easy washing, good elasticity, and no pilling. It is completely suitable for making high-end leisure Suit fabric.

Description

technical field [0001] The invention relates to a preparation method of a fabric, in particular to a preparation method of a ramie wool elastic fabric, which belongs to the field of textiles. Background technique [0002] With the advancement of textile science and technology and the continuous improvement of human performance requirements for textiles, people have put forward higher requirements for the feel and visual effects of clothing fabrics. [0003] Ramie is a unique hemp resource in my country, and is called "Chinese grass". my country is the main producer of ramie in the world, and ramie output accounts for more than 90% of the world's total output. Ramie fiber is a natural green ecological fiber, which has excellent properties such as moisture absorption, breathability, fast heat conduction, fast moisture dissipation, antibacterial, anti-mite, anti-mildew, anti-ultraviolet, and static electricity. It is caused by its unique natural functionality and biodegradabili...

Problems solved by technology

[0004] Due to the constraints of objective conditions such as low ramie single fiber count (1400Nm-1800Nm), thick and hard fibers, large Young's modulus, poor single-fiber uniformity, and large length variation coefficient (length distribution in the range of 20-250mm), it is difficult to Spinning high-count yarn, conventional products are 7.5Nm ~ 36Nm ramie yarn and cloth and other middle and low-grade products, and the wearing performance is affected by reasons such as ramie products have many hairiness, low elasticity, strong itching, etc.

[0005] In addition, ramie is prone to quality problems such as color flower, color difference, and not bright color. Ramie fiber also has shortcomings such as strong rigidity but insufficient toughness, unevenness, and poor cohesion between fibers. There are certain difficulties in the spinning process. There are many worsted wool and linen blended products, the appearance is similar to ordinary worsted fabrics, lacks the appearance effect of intermittent hemp knots, and has poor elasticity, poor wearing performance, and easy to wrinkle
