A kind of plant fiber blended fabric and its processing method

Abstract

The invention provides a plant fiber blended fabric and a processing method thereof. First, lyocell fibers and bamboo fibers are spun to obtain warp yarns through compact siro spinning, and then modal fibers, mugwort fibers, grass coral fibers and aloe fibers are vortexed. Weft yarns are obtained by spinning, and then the warp yarns and weft yarns are subjected to enzymatic hydrolysis treatment and fermentation treatment respectively, and then staggered and overlapped weaving along the warp and weft directions to obtain gray fabrics, and then finished. The invention realizes the blending of various plant fibers through composition adjustment of warp and weft yarns, enzymolysis treatment, fermentation treatment and post-finishing treatment, and the obtained fabric is smooth and crisp, has strong sagging feeling, good wrinkle resistance and high mechanical properties.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a plant fiber blended fabric and a processing method thereof. Background technique [0002] In people's daily wear, except for a small amount of clothing made of natural fibers such as cotton, hemp, silk, and wool, most of them are made of chemical fiber spinning and weaving made of chemically synthesized polymer compounds as raw materials. Apparel, such as polyamide cellulose (nylon), polyester fiber (polyester), polyacrylonitrile fiber (acrylic fiber), polyvinyl formal fiber (vinylon), etc., most of the chemical fibers are extracted from petroleum Organic substances are then made into fibers by chemical synthesis and mechanical processing. Chemical fibers, especially polyester and nylon, are widely used in people's daily life such as clothing. In addition, another form of chemical fiber is man-made fibers. Man-made fibers are made of certain linear natural polymer ...

AI Technical Summary

Problems solved by technology

[0005] 2. Chemical synthetic fibers are generally non-degradable like plastics. The waste will cause serious environmental pollution on the earth's surface. The only way at present is to recycle

[0035] 1. The range of raw materials suitable for vortex spinning is limited to short chemical fibers and medium-length fibers. Due to the quality of the yarn, the competitiveness in the field of fine yarns is not strong.

[0036] 2. The yarn structure of eddy current spinning is relatively loose, and the uniformity of long segments is good. The evenness of yarn is generally close to the level of ring-spun yarn, but the thickness unevenness of very short segments is more obvious than that of ring-spun yarn, but the strength is higher. Low and unstable, limiting its development to the fine-gauge yarn field

[0037] 3. Although vortex spinning uses air vortex to replace the rotor of air spinning, which overcomes the problem of wear caused by the high-speed rotation of the rotor of air spinning and the problem of excessive bearing load, it still cannot solve the problem that the yarn tail at the free end is in the vortex. The yarn arm formed when the tube rotates at high speed, which leads to the problem of large centrifugal force and tension

Therefore, it is impossible to have a breakthrough in its spinning speed.

[0038] 4. Due to the poor straightness of the fibers and the short coagulation process of the vortex spinning yarn, the yarn structure is loose and the strength of the yarn is low. Therefore, its products have limitations and are only suitable for chemical fiber raw materials and spinning rough numbers. Products that do not require high strength such as knitting yarn or thick pile yarn, or spinning core-spun yarn with filament as the core

[0039] Therefore, one of the most notable characteristics of plant fiber vortex spinning is that the surface of the yarn is relatively hard, the strength of the yarn is relatively low, and the resulting fabric feels hard. Even if a softener is added after printing and dyeing, it is difficult to completely solve the problem of hard feeling. The plant fiber compact siro spun yarn is relatively soft, and the yarn strength is relatively high, and the fabric made is soft and lacks a stiff skinny feeling.
