The spun yarn of quantification of 0.89g/100m is made in comb, drafting, rove, spun yarn, comprising the following steps:
Step 1: distributing cotton: according to the method for classification and queuing, ingredient is matched based on Xinjiang Long staple cotton and the length of medium staple cotton
Cotton；Larger with cotton total amount due to using griping cotton machine mixed cotton, the setting of team's number should be more, and 9 teams are arranged in Xinjiang Long staple cotton；And it uses with each
Ground medium staple cotton, the vast kind in raw cotton producing region is complicated and quality difference is larger, and in order to which batch number is changed in stability property reduction, team's number is set
Setting should be more, and medium staple cotton team number is set as 19 teams；The characteristics of according to reciprocation bale plucker, the master tested in conjunction with different raw cotton
Performance indicator is wanted, the row's of arranging properly packet figure guarantees that the cotton quality grabbed every time is stablized；
Step 2: long-staple cotton Blowing carding: including opening or cleaning process and carding step, carding step task includes shredding, removal of impurities,
Mixing, uniformly strike phase is freely hit and hold to coiled four aspects using multiple hoppers, to guarantee mixing and shredding effect
In conjunction with mode carry out shredding and removal of impurities, original of each single machine according to " even grab carefully grab, big miscellaneous caducous few broken, shredding is to comb for beating "
Then, the weight for reducing crawl flock block, makes impurity be sufficiently exposed to the surface of flock, reaches control short flannel and increases and opening or cleaning line cotton
Knot increases high purpose；Selection holds strike after first freely hitting, and makes shredding by mitigating to acutely, gradually shredding is realized, to subtract
Few damage to cotton fiber；For grabbing cotton process, setting adapts to the different cotton packet of four kinds of height, while supplying two opening or cleaning lines,
Memory sponge packet height in operation, adjust automatically grab depth, make just different cotton packets finally while having grabbed, grab cotton hired roughneck's vehicle
Speed reaches 1200-1400r/min；For more storehouse mixed cotton processes, supplement cotton using each storehouse is outer at random, every storehouse output speed is different, often
Storehouse storing highly is different, is mixed on output cotton curtain, every storehouse following settings hired roughneck is further to decompose flock, Beater Speed
500r/min；For scutching cotton dedoping step, work range 1.5m is set, first hired roughneck is foot staple, is surrounded by sawtooth with one

The uniformity；For roller loading, roller loading needs that roller nip is kept to have enough curable grips, to overcome drafting force, prevents
Yarn big sliding velocity lamination under roller nip, pressuring method are Spring cradle pressurization, and the gripping of front roller nip
Power is set greater than rear roller；
Step 8: rove: including three processes, drawing-off: ripe bar attenuating being drawn and attenuated 8-10 times, stretches fiber in sliver further
In parallel, it prepares for spun yarn drafting, using the double-short leather-ring drawing-off of four rollers, three draft area, the wherein drawing-off between 1-2 roller
Multiple is set as 1.05 times, for Distribution Area, the condensers before Distribution Area is provided with, and selecting the bore of preceding condensers is 5,2-3
It is main drawing area between roller, condensers is not placed in main drawing area, realizes that constriction beam not drawing-off is not concentrated in drawing-off, is improved with reaching
The purpose of bar evenness, to arrange condensation region between 3-4 roller, fiber after making main drawing area drawing-off is risen arranging condensation region
It is acted on to boundling, the condensers after arranging condensation region and being provided with, and the bore of condensers is 12 after selecting, for drawing rollers
It holds away from the size of drafting force is comprehensive in the uniformity and draft area depending on the quality length Lp of fiber, and referring to fiber
Consider, do not open fibrous fracture or yarn drawing-off as principle, wherein the back zone between 3-4 roller is simple roller draft,
It is held due to there is collector away from can suitably amplify, since the quality of pure cotton fiber is long using the process for big gauge of pressurizeing again
Degree is 36mm, and the Distribution Area between 1-2 roller is held away from being set as 38mm, including roller diameter 28mm and gauge 10mm；Twisting:
Yarn after drawing-off is added into the twist appropriate, makes rove that there is certain strength, prevents misdraft or break, rove twists system
Number grasp slightly bigger than normal, is conducive to stable yarn quality, and actual production process selects roving twist factor 105；Winding shaping: will add
The package for meeting necessarily required shapes and sizes is made on roving bobbin in reeling roving after twirl, to store, to carry and
The feeding requirement of spinning frame is adapted to, four lower double-short leather-ring D type drawing-offs, preposition by the collector of main drawing area in use four, reality
Row drawing-off is separated with boundling, length of floating area is reduced, to improve bar evenness；
Step 9: spun yarn: using the double draft area drawing-offs of three rollers, length apron, Suessen Pendulum Weighting Arm System, grid ring compact spinning, collection
Middle vacuum cavitations select 2.7 pressure bar jaws, shorten free section length, to reduce floating fiber, reinforce to fiber movement
Control improves Spinning Evenness；Proparea gauge is reduced, back zone gauge is amplified, reduces back zone drafting multiple, proparea is concentrated to lead
Upper and lower cushion rubber is stretched outside under effective control of sliver, spun yarn proparea yarn density is improved, reduces scattering and disappearing for edge fibers and short flannel,
Filoplume is effectively reduced, long details is reduced, improves strength；First break draft area uses curve drawing, and drafting multiple grasp less than normal is led before being
It stretches area and the uniform yarn of structure is provided, using " tight gauge is pressurizeed " again, be conducive to the movement for controlling draft area fiber, improve defeated
The uniformity of yarn out, first break draft area roller gauge use 38mm；Front draft zone Draft Configuration technique meet before, sieve of middle roller
Drawing center uses 18mm away from principle small, that area of swimming is small and cushion rubber nip gauge is small, front draft zone roller gauge.
