Production method of ramie spinned high count yarn and compound yarn

Abstract

The invention provides a production method of ramie spinning high grade plied yarn, which is characterized by comprising the steps: union yarn is manufactured by cospinning ramie and water-soluble vinylon, is boiled by water for vinylon dissolution, and then is rinsed and dried, so that ramie single yarn with the fineness of 100-300Nm; then, the plied single yarn is made into ramie pliedyarn having the fineness of 100 / 2-300 / 2Nm. The production method has the advantages that as the water-soluble vinylon is introduced, the spinnability of the ramie is improved, and the spinnable fineness of the ramie yarn and thread is greatly reduced; furthermore, the single twist multiplier can be properly reduced, and the coefficient of twist of the plied yarn can be selected reasonably according to the twisting theory, so that the resultant yarn structure of the plied yarn is more compact, the yarn body is brighter and cleaner, less filoplume is available, and the uniformity of yarn levelness is better, thus ensuring the whole quality of the plied yarn to be excellent. Therefore, the excellent properties of the ramie are fully exerted, the application scope of the ramie products is enlarged, and the method is suitable for producing the thin ramie products with high quality.

Description

technical field

[0001] The invention relates to a production method of ramie spinning high-count strands, which belongs to the technical field of textile engineering. Background technique

[0002] Ramie fiber has high strength, fast moisture absorption and moisture dissipation, good air permeability, antibacterial, and excellent wearability. It is a widely favored green textile raw material. However, because of its high rigidity, stiffness, and insufficient flexibility, the yarn count is low and the hairiness is high, and the spinnable count is low (36-48 public counts), and the woven fabric has a strong itching feeling, which limits the application of ramie products. . For a long time, people have been committed to the research of high-branching of ramie, but the progress is limited. The existing method of spinning high-count yarn of ramie usually adopts blending of ramie and water-soluble vinylon to make a blended yarn, and after weaving into a fabric, it is processed in ...
