After fiber carries out appropriate shredding pretreatment, the mass ratio required according to yarn is mixed with natural fiber or cellulose fibre,
Ensure that ratio is accurate, is uniformly mixed；
2) opening picking：The short cord Luo Na length of elasticity is long, and regularity is good, and rigidity is small, and curling is more and flexible, easily twists together,
So in opening and cleaning step using " fine crawl, more pines beat less, and anti-sticking lap guard is sufficiently mixed " technological principle, hired roughneck's gauge is suitable
Work as amplification, reduces kirschner beater and comprehensive Beater Speed, fiber is avoided to cross poly-injury and tangle；

830r/min；Licker-in is 1 with cylinder differential surface speed:2.1；Doffer speed is 18r/min；Licker-in-cylinder gauge (mil) 7；Cylinder-
Flat Gauge (mil) 12,10,9,9,10；Cylinder-doffer's gauge (mil) 5；
4) drafting：Since the short cord Luo Na resiliences of elasticity are good, to reduce fibre hook, the stretched straight parallel of fiber is improved
Degree ensures fiber control of the fiber in stretch exercise, reasonable Draft Configuration, head and the grasp bigger than normal of first break draft multiple, total draft
Multiple grasp less than normal；Two simultaneously first break draft multiple grasps less than normal, total draft multiple grasp bigger than normal；Rational Draft Configuration does not only reach
Improve weight unevenness, and improves Fiber Straightness and do not deteriorate the dry purpose of item and improve and do not controlled because of fiber rebound
The presence of the spinning yarn defect of system.
It is mixed simultaneously using twice；It is 6*6 to feed radical；Drafting main technologic parameters：1. head is simultaneously：It is dry to determine weight 20.0g/
5m；Weight stretches oneself and yawn multiple 5.64；Stretch oneself and yawn multiple 1.670 in back zone；2. two simultaneously：It is dry to determine weight 17.5g/5m；Weight stretches oneself and yawn multiple
6.857；Stretch oneself and yawn multiple 1.326 in back zone.
