2 Improper treatment of fine China polyester yarn fibers in the carding process tends to increase the short-pile rate and produce neps.5%, and the temperature and humidity of the workshop shall be controlled within 60-65%.5g/5m, sliver speed 100m/min, cylinder speed 350r/min, spur roller speed 740r/min, doffer speed 28r/min, cover speed 111mm/min, cylinder and Cover plate spacing 0.22, 0.5 Spinning process

The spinning process adopts the technological principles of 'large drafting, re-pressurization, larger gauge and rear zone drafting'. Table 1 Main technical parameters of the draw process 1.6 Winding process To meet customer needs, strictly control the technological parameters of the electronic yarn clearer, optimize splicing parameters and splicing equipment to ensure splicing strength, and the winding speed is 1000r/min. 1.1

The fine-denier Modal fiber in the clearing process is slender, has large friction and strong cohesion, and is easy to kink during the spinning process.25 times, twist factor 64, spindle speed 850m/min, roller gauge 12. Key words: fine denier Modal; process; speed; quantitative; draft multiple; gauge; temperature and humidity; frictional force Modal high-density fabric has the characteristics of high hygroscopicity, strong air permeability, soft skin-friendly, good drape, dimensional stability, etc.18mm.5mm, workshop temperature maintenance Above 28 ℃, humidity is controlled at about 70%, test strip dry CV%: 3.25, 0.7mm shall be controlled within 1. It selects soft elastic rubber rollers with a Shore hardness of 65-68, and the upper and lower aprons are used together. 1.

Therefore, the clearing process adopts 'more loose 'Beating, low speed, light blow' process principle, minimize fiber damage and neps.7%, moisture regain rate 11. The sliver neps shall be controlled below 3 grains/g, the short pile rate below 12.2%.3 Drawing process Drawing process adopts the process principle of “light weight, large gauge and heavy pressurization” to facilitate straight stretching of fibers and reduce hooks.
