However, the Shengma fiber has the following problems: because it is easy to generate a large amount of static electricity, it will cause the fiber web output by the doffer on the carding machine to float up and cannot be stably output; The medium cohesion force is small and easy to slip, which brings certain difficulties to the spinning process; the strength is lower than that of cotton fiber, and it is more difficult to spin high-count yarn of Shengma fiber than spinning high-count yarn of cotton fiber. In the process of quality control, improving the strength of Shengma yarn and reducing the yarn hairiness of Shengma fiber are the key to ensure the quality of Shengma fiber, and it is also the difficulty of spinning high-count yarn with Shengma fiber
[0003] The strength of Shengma fiber is relatively low and the shrinkage is relatively large, the yarn has more hairiness, and the texture of the fabric is not strong

Embodiment Construction
[0021] The present invention first selects suitable holy hemp fiber, holy hemp fiber production line and cotton fiber, cotton fiber production line, specifically as follows:
[0022] Shengma fiber conditions: dry breaking strength 2.5CN / dtex, wet breaking strength 1.5CN / dtex, dry breaking elongation 24%, whiteness 72-74%, oil content 0.2-0.4%, public moisture regain 13%, crystallinity 40%, water absorption rate 1100%, specific resistance 5.3×10 8 Ωg / cm 2 , The number of curls is 2 / cm, and the joint strength is 1.23CN / dtex.
[0023] Shengma fiber production line adopts A002C automatic plucking machine, A036B porcupine opener, A092A double cotton box feeder, A076C lapping machine and A186D carding machine.

Abstract
The invention relates to a method for producing blended yarn of Shengma fiber and cotton. A required cone yarn is produced by selecting suitable Shengma fibers and cotton fibers, combining the Shengma fibers with a cotton comber on a drawing after blowing, carding and predoubling, and performing a roving process, a spinning process and a winding process. In the method, the blowing process has thecharacteristics of carding more and beating less, catching frequently and rarely, low beater speed, less fly fiber, and heavier pressure; the carding process has the characteristics of suitable carding; the drawing process has the characteristics of light quantitation, heavy pressure, low speed, primary predoubling and secondary blending; the roving process has the characteristics of light quantitation, heavy pressure, low speed and high twisting degree; and the spinning process has the characteristics of low speed, high twist factor and suitable temperature and humidity. A plus material of the blended yarn of the Shengma fiber and the cotton produced by the method of the invention has cotton texture; a fabric has the characteristics of soft, smooth and fluffy handfeel, high moisture adsorption performance and ventilation property, high warmth retention property, high bacteria and mildew resistance, high drapability, bright color and luster, plump and smooth fabric surface organization, lightness and comfort for a wearer, and capacity of being used for knitted underwear, leisure wear, towel supplies, beddings and the like.
Description
technical field [0001] The invention relates to a production method of Shengma fiber and cotton blended yarn. Background technique [0002] Shengma fiber is a new type of cellulose fiber developed with its own patented technology based on the widely produced hemp material. The fiber has the characteristics of good moisture absorption, breathability, antibacterial and mildew resistance. With good drapability, bright color, and full and smooth cloth texture, it is a new, healthy, fashionable, green and environmentally friendly ecological textile fiber. However, the Shengma fiber has the following problems: because it is easy to generate a large amount of static electricity, it will cause the fiber web output by the doffer on the carding machine to float up and cannot be stably output; The medium cohesion force is small and easy to slip, which brings certain difficulties to the spinning process; the strength is lower than that of cotton fiber, and it is more difficult to spin ...
