Problems solved by technology

[0004] Although silkworm fiber is a viscose fiber with high-tech content and has some properties of viscose fiber, it is also different. The following problems exist in the production process: 1. The silkworm fiber has little moisture regain and serious static electricity. The phenomenon of rollers and aprons is serious, and the phenomenon of cotton web returning flowers is easy to occur in the carding process, which seriously affects the production and quality of sliver; 2. The strength is lower than that of cotton fibers, and the number of fiber curls is small. Neps are produced, which affects the appearance quality; 3. The yarn forming strength is low, and the yarn breakage is high, especially for pure spinning with 60 counts, the yarn count is high, and the yarn is thinner, which is more difficult than spinning medium and low count yarns

Embodiment Construction

[0024] The present invention selects suitable jade silkworm fiber by pure spinning 60-count high-count yarn with jade silkworm fiber. Conditions of jade silkworm fiber: specification 1.67dtex×38mm, dry breaking strength 2.18CN / dtex, wet breaking strength 1.12CN / dtex, dry breaking elongation 15%, moisture regain 8%, ultra-long fiber rate 0.3%, oil content 0.18%, defect 1.5 mg / 100g, double long fiber 1.2mg / 100g,

[0025] The production line of the present invention adopts A002C automatic cotton picker, A035C mixed opener, A036B porcupine opener, A092A double box feeder, A076C roll forming machine, A186D carding machine, A272F drawing frame two-pass, RD22C drawing frame Machine 1 (installed with autoleveling device), A456 roving frame, DTM129 spinning frame (installed with compact spinning device), 21C Japan Murata automatic winder.

[0026] The production steps are as follows: after the jade silkworm fiber is cleaned, carded, and drawn in three passes, the required yarn is prod...

Abstract

The invention relates to a method for producing jade silkworm fiber pure 60s compact spinning yarn. Needed cheese yarn can be produced by jade silkworm fiber through processes of roving, spinning and spooling after the processes of blowing, carding and three-passage drawing. According to the method disclosed by the invention, the blowing and carding processes have the advantages that scutching is replaced by carding, the shifting is quick, the winding is prevented, and the fiber damage is reduced; the drawing process adopts the three-passage drawing, thus the weight irregularity of a silver is reduced, and the evenness of a drawn silver is improved; the roller gauge of the roving process and the tension of a cradle are appropriately enlarged, thus the roving tension is controlled, and the additional draft is reduced; a spinning machine is additionally provided with a four-roller grid ring-shaped compact spinning device; and the electric cleaning technology is optimized by the spooling process. According to the method disclosed by the invention, the quality of the compact spinning yarn which is produced through the method is better, the silver evenness, the hairness and the force index of the compact spinning yarn are all better than those of a common ring spinning yarn, and the compact spinning yarn is the qualitative material of textiles, contacting the skin of a human body, such as high-grade underwear, shirts, pillow and quilt cases, bedclothes, scarfs and socks; and weaving dresses and casual clothes made by of the jade silkworm fiber are fresh in color, smooth and gentle in silky brightness and flexible in overhanging elegant innervation.

Description

technical field [0001] The invention relates to a method for producing pure 60-count compact spinning yarn of jade silkworm fibers. Background technique [0002] Jade silkworm fiber is a new type of protein viscose short fiber, the production process is similar to ordinary viscose fiber. It is a functional fiber that is modified and co-spun by mixing a certain proportion of vegetable protein in the production process of viscose fiber. The special skin-friendly effect of several amino acids required by the human body, the personal care of emitting far infrared rays and stimulating negative ions, strong moisture absorption and breathability, silky smooth, not easy to wrinkle after repeated washing, and not easy to lose long-term health care functions. Especially suitable for textiles such as underwear, shirts, pillow covers, sheets, scarves, socks, etc. The knitted dresses and casual clothes made of jade silkworm fiber have bright colors, smooth silky luster, flexible drape ...
