Preparation method of ramie wool stretch fabric

Abstract

The invention discloses a preparation method of ramie wool stretch fabric. The preparation method comprises the steps that 1, fine spinning is adopted by warp yarn, the yarn count Nm ranges from 50/2 to 60/2, fine spinning is adopted by weft yarn, the yarn count Ne is 50/2 and 32/1 by combining with spandex, and gray fabric is obtained by spinning the warp yarn and the weft yarn by adopting the 2/2 weave and the total tightness ranging from 100 to 105; 2, after finishing is conducted, the steps of gray fabric shaping, singeing, continuous boiling, washing shrinking, double boiling, drying, middle inspection, medium repair, brushing, napping, water washing, drying, shaping, shearing, softening and tank decatizing are sequentially conducted, and a finished product is obtained. White ramie is adopted to be added in the last gilling of recombing, the characteristic that ramie stripes are not prone to being evenly mixed is utilized, and the bamboo joint effect of the cloth cover of the finished produced is achieved; only the finisher gilling and a line of rough yarn are adopted in the spinning workshop section; the water washing technology is adopted during the after finishing to improve the size stability of the fabric; by means of the napping technology, slight fluff occurs on the cloth cover, the sense of warmth and the degree of softness of the fabric are enhanced, and finally the ramie wool stretch fabric has the advantages of being easy to wash, good in elasticity, not prone to pilling and fuzzing, fully suitable for being used for making upscale leisure suits and the like.

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...

AI Technical Summary

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
