Abstract

The invention provides a polylactic acid fiber yarn and a manufacturing process thereof. The process includes six processes of cotton cleaning, cotton carding, drawing, roving, spinning and winding, wherein the cleaning process includes application cooperation among an automatic cotton grabbing machine, a mixed cotton opener and an cotton opener after parameter adjustment of each device. Lap enters into the cotton carding process after cotton cleaning process, under the action of a carding machine, the lap become cotton slivers and the slivers enter into a drawing frame, then enter into a roving machine and a spinning machine, and finally enter into a winder. The manufacturing process provides a market with a yarn made of a new environment-friendly material, people's dressing experience can be improved, the market demands can be met, and economic and social development can be promoted.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a polylactic acid fiber yarn and a manufacturing process thereof. Background technique [0002] With the improvement of living standards, people begin to develop in the direction of health, environmental protection, fashion, comfort and functionality in terms of clothing. Traditional cotton, linen, silk wool and petroleum-based synthetic chemical fibers can no longer meet the raw material requirements of modern clothing. The development of green environmental protection fiber and natural functional fabrics has become a research hotspot. [0003] In recent years, in the textile and garment industry, polylactic acid fiber has begun to receive people's attention. The initial raw material for the synthesis of polylactic acid fiber is fermented from cornstarch, which comes from natural resources and is rich in resources without using petrochemical raw materials. Polylactic acid fib...
