Siro spinning fine ramie and production method for superfine yarns

Abstract

The invention provides a siro spinning fine ramie and a production method for superfine yarns, which is characterized in that the method comprises the following steps of: adopting a siro spinning method to mix the ramie roving and water soluble vinylon roving on a spinning frame during the traction process, thus spinning the blended yarns; removing the vinylon of the blended yarn in water, washing the blended yarn by water and drying the blended yarn to prepare the fine ramie with the fineness of 100-300 counts; combining the single yarn to prepare the ramie superfine yarns with the fineness of 100 / 2-300 / 2 counts. Compared with the method of combining firstly and removing vinylon lately, the method can prepare single yarns, can select the twist factor of the threads more reasonably by aiming at the twist of the single yarn, and lead to much compacter yarn-forming structure of the threads, smoother yarn body, less feathers and better yarn evenness uniformity, thus leading to better whole quality of the threads; furthermore, the method sufficiently plays the excellent performances of the ramie, enlarges the application fields of the ramie product and is suitable for producing fine and high-class ramie products.

Description

technical field [0001] The invention relates to a production method of siro-spun ramie high-count yarn and high-count strand, belonging to the technical field of textile engineering. Background technique [0002] Ramie is a special product in my country. The ramie textile industry is an industry with comparative advantages in the world. It plays a pivotal role in the world's hemp textile industry and has absolute advantages in resources. More than 95% of the world's ramie is produced in China. It is known as "Chinese grass" in the world. It has high strength, fast moisture absorption and moisture dissipation, good air permeability, antibacterial, and excellent wearing performance. It is a widely favored green textile raw material. However, because of its high rigidity, stiffness and lack of flexibility, the yarn count is low and the hairiness is high, and the spinnable count is low (36-48), and the fabric woven by it has a strong itching feeling, which limits the application...

AI Technical Summary

Problems solved by technology

[0004] 1. Although the count of ramie yarn is very high in the fabric woven into finally, the high-count ramie yarn (thread) used alone cannot be made;

[0005] 2. The variety and quality of products produced are limited, which restricts the promotion of ramie products and the development of ramie industry;

[0006] 3. After the fabric is de-dimensionalized, the density and strength of pure ramie fabric are very low, so it can only be used as gauze scarves, etc., and cannot be used as clothing fabrics, etc.;

[0008] 5. The mixing method used is loose fiber mixing or sliver mixing. It may appear that a certain part of the yarn is distributed in the cross-section of vinylon, which will cause broken ends after the fiber is withdrawn. In addition, when loose fiber or sliver is mixed, There must be a part of vinylon distributed in the inner layer of the yarn, which will make it difficult to return the dimension
