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...
