Method for preparation of colorful rotor-spinning viscose stocking yarns

Abstract

The invention relates to the technical field of yarn preparation, in particular to a method for preparation of colorful rotor-spinning viscose stocking yarns. The method includes the steps: 1) selection and matching of raw materials; 2) pretreatment of dyed viscose fibers; 3) bale arrangement; 4) blowing and carding; 5) drawing; 6) rotor spinning; 7) final inspection and baling. Due to adoption of the technical scheme, the prepared colorful rotor-spinning viscose stocking yarns are novel yarns made by blending of various colorful viscose fibers, and later-stage spinnability of the dyed fibers is greatly improved due to oil feeding treatment of the dyed fibers in preparation. Fabrics made of the yarns integrate advantages of all of the raw materials and are skin friendly, soft, elegant and glossy, the yarns made by an international most advanced rotor spinning machine have the advantages of uniformity in unevenness, flawlessness, knot avoidance, smoothness in handfeel, high abrasion resistance and the like and are most ideal raw materials for high-grade knitted underwear, and successful development of the colorful rotor-spinning viscose stocking yarns opens a new field of rotor-spinning yarns.

Description

technical field [0001] The invention relates to the technical field of yarn preparation, in particular to a method for preparing rotor spun viscose colored knitting yarn. Background technique [0002] With the development of society and the improvement of people's living standards, people's requirements for clothing have gone beyond the simple comfort and aesthetics. Green, environmental protection, safety and health care have become important conditions for consumers to choose clothing. Rotor spinning technology is a new type of spinning category. Originally, it was based on a single natural color yarn. With the introduction of imported advanced rotor spinning equipment, the green and environmentally friendly cellulose fiber-viscose fiber is used on rotor spinning equipment.

Problems solved by technology

Rotor spinning technology is a new type of spinning category. Originally, it was based on a single natural color yarn. With the introduction of imported advanced rotor spinning equipment, the green and environmentally friendly cellulose fiber-viscose fiber is used on rotor spinning equipment. Continuous development, the development potential of rotor spinning colored viscose yarn products is great, but because of the fast speed and high output of rotor spinning, and the low strength of colored viscose fiber and dyed viscose single fiber, the rotor spinning The spinnability of advanced technology and the guarantee of product quality put forward higher requirements. Therefore, to ensure the spinnability and quality requirements of the product, to achieve the expected output target, to find a suitable production method of rotor spinning colored viscose yarn and There is no successful experience in technology, only exploration and exploration. Once successful, the market potential and social benefits will be huge.
