Embodiment Construction

[0024] A method for producing high-strength and low-shrinkage bio-based fiber yarn, comprising the following steps:

[0025] (1) Opening and cleaning process:

[0026] Choose Yasser TM Type II fiber, specification 1.22dtex×38mm, dry cracking strength ≥ 3.2CN / dtex, wet breaking strength ≥ 1.8CN / dtex, dry breaking elongation 13~16%;

[0027] According to the characteristics of Yasser fiber, the fiber must be sent to the workshop for pre-loosening treatment before spinning, and it will be automatically balanced for 24 hours to ensure that the moisture regain of the fiber on the machine reaches more than 11%, so that the surface state of the fiber can be improved and the spinnability can be improved. sex. The opening and cleaning process follows the process principle of "fine grasping, gradual opening, and combing instead of beating".

[0028] During the cotton opening and cleaning process, the nep growth rate of the cotton lap is controlled at 80~85% compared with the raw cott...

Abstract

The invention discloses a production method of high-strength and low-contraction biological base fiber yarn. The method comprises the following steps of an opening picking process, a cotton carding process, a drawing process, a roving process and a sprun yarn process. The method has the advantages of being high in strength and low in contraction. The requirement of a home textile fabric for high strength and shrinkage rate is met, the fiber performance advantages of Yasaier are brought into full play, the yarn is widely applied in the field of home textiles, the development of the domestic biological base fiber industry is forcefully promoted, and meanwhile updating and transformation and upgrading of home textiles are promoted.

Description

technical field [0001] The invention relates to a production method of bio-based fiber yarn. Background technique [0002] In recent years, due to the shortage of cotton resources and the upside-down of cotton prices at home and abroad, the economic situation of the home textile industry has been seriously affected. Accelerating the research of new home textile materials is an important task for the R&D personnel of the home textile industry chain to solve. Through the joint efforts of R&D personnel and cellulose fiber manufacturers such as Austrian Lenzing Company, cellulose fibers such as Tencel and Modal have been widely used in the field of home textiles. The product came into being in the home textile market. Judging from the market development trend in the past two years, due to the price factor of Tencel and Modal home textiles, the cool feeling of Tencel and the strong feeling of chemical fibers, and the poor anti-pilling of Modal, although these home textile produc...
