Problems solved by technology

[0004] However, the above-mentioned fibers have the following disadvantages: polylactic acid fibers have high elongation at break, strong resilience, high friction resistance during production, and are prone to wrinkles
Because of the above-mentioned deficiencies, when the two fibers are spun in the prior art, it is impossible to obtain medium-count yarns or high-count yarns with finer yarns and good quality.

Embodiment

[0052] Polylactic acid fiber is blended with combed fine-staple cotton to produce compact spinning, which is produced through the following process steps:

[0053] 1) Cleaning process

[0054] In order to protect the polylactic acid fiber from being damaged as much as possible, the process should be shortened as much as possible, and the impact method should be reduced as much as possible. Increase the opening. The falling speed of the beater of the cotton catching machine is 3mm each time, the speed is 960r / min, the speed of the rotary trolley is 2.8r / min, the blade extends out of the rib 3mm, the speed of the beater is 800r / min, the speed of the fan is 950r / min, the distance between the beater and the balance roller is 12mm, Lap roller speed 12r / min,

[0055] Polylactic acid fiber: the dry weight of the lap is 374g / m, and the length of the lap is 30.6m;

[0056] Fine-staple cotton: the dry weight of the lap is 375.5g / m, and the lap length is 36.5m;

[0057] 2) Carding pr...

Abstract

The invention belongs to the technical field of textile, and particularly relates to compact spinning yarn produced through polylactic acid fiber and combed fine stable cotton blending and a production method and application of the compact spinning yarn. According to the production method, polylactic acid fiber and combed fine stable cotton serve as raw materials, and the compact spinning yarn with the number being 40 is obtained through the processes of blowing, carding, combing, drawing, roving, spinning and spooling. According to the production method, parameters of all the processes are qualified definitely so as to make the polylactic acid fiber and the combed fine stable cotton blended smoothly to obtain the compact spinning yarn with the number being 4; fabric produced through the compact spinning yarn is good in gloss and skin adaptability and smooth and delicate in hand feeling, the fabric has the excellent drapability and flexibility, the natural antimicrobial and moisture absorption and sweat releasing properties are excellent, the elastic recovery is good, and the compact spinning yarn can be used for making underwear and sportswear.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to compact spinning produced by blending polylactic acid fiber and combed fine-staple cotton, as well as its production method and application. Background technique [0002] With the enhancement of human awareness of earth protection and energy depletion, ecological fibers that are environmentally friendly and recycled are gradually favored by people. Polylactic acid fiber is an ecological fiber with great development potential. Polylactic acid fiber is a lactic acid polymer synthesized from lactic acid contained in the human body. It has good skin affinity and resilience, and is soft and comfortable. Products using polylactic acid fiber will not cause skin allergies and have good moisture absorption and air permeability. Polylactic acid fiber has the advantages of both synthetic fibers and natural fibers, and at the same time has the characteristics of complete natural...
