Abstract

The invention discloses a Carex meyeriana blended yarn production method. Tencel fiber is regenerated cellulose fiber, sweat-absorbent, breathable and can keep warm and cool, the Tencel fiber is comfortable to wear, the strength elongation property is high, the Tencel fiber also has the handle of silk and is the most ideal material for light and thin fabric, so that the blended yarn with higher quality can be obtained by blending of Carex meyeriana fiber and the Tencel fiber. The Carex meyeriana / Tencel blended yarn explores a new space for the development of Carex meyeriana products. The technological process comprises blended materials, a blowing-carding unit, a drawing frame (three-lines) and an air-jet spinning machine in sequence. The method is characterized in that raw materials are pre-processed, a reasonable raw material blending technology is chose, a reasonable technological process is determined, parameters of all fore-spinning working procedures are configured accurately, and optimized air-jet spinning technology parameters are determined. According to the Carex meyeriana / Tencel blended yarn produced through air-jet spinning, the blended yarn with a good balance between all performance indexes such as even yarn, little hairy yarn, even strength, good anti-friction, anti-pilling property is obtained.

Description

technical field [0001] The invention relates to a production method of Ulagrass blended yarn, which belongs to the technical field of textile industry. Background technique [0002] In recent years, people have paid more and more attention to the development and utilization of new natural fibers. Ulagrass is a new type of environmentally friendly fiber. The development and utilization of Ulagrass will have far-reaching significance from the perspective of energy and environmental protection. Ulagrass has the effect of keeping warm and moisture-proof, and can resist fungal erosion and parasitism. However, due to the slightly poor cohesion and softness of the ulagrass fiber obtained at present, and the uneven length of the fiber, it is difficult to spin alone or in the spinning process. In our experiments, we found that the use of blended yarns can reduce the difficulty of the spinning process, and can be beneficial to the development of ulagrass products, so as to make bette...
