Step is dry for improving the ripe rule in 3., head also adopts less first break draft multiple, two also to adopt the mode of concentrating drawing-off, adopt drafting roller gage less than normal simultaneously, the mode that also employing is heavily pressurizeed improves the extended parallelization of fiber: an also dry quantitative 17.3g/5m of being, output speed are that 350m/min, merging number are 6, two and dry quantitatively for 15.5g/5m, output speed are that 500m/min, merging number are 8, head first break draft multiple are 1.54, total draft multiple is 7.66, two and first break draft multiple is 1.42, total draft multiple is 8.9; The main technologic parameters of drafting is in table 2.
Table 2: drawing process parameter
Key problem in technology point:
1, for viscose and rubber rollers friction generation electrostatic phenomenon, adopt the suitably favourable static of increase humiture to discharge, every 3 days of while is with hot cloth wiping roller surface and enclose the finish on bar dish.Per tour is exchanged one time three and front and back roller, prevents because of the overheated impact on the roller life-span of high speed rotary roller.
2, drawing of fiber region is too wide, and fiber is easily dispersed and caused around roller at edge, draw zone, affects productive life, and contraction draw zone width is conducive to control fiber and disperses.
3, the surface treatment of drawing belt roller is to solve the mixing in doubling step key of doing of living, in employing, be coated with after the RC general purpose rubber coating without Ceylon's Xiang, thoroughly change around a roller difficult problem, through test of many times coating formula A: B=1: in 2 plate painting methods, to deposit upper machine after three days be the best on three limits.

3, select import apron, it is flat that its good surface property is conducive to improve rove bar solid carbon dioxide.
4, RC universal lacquer on roller, proportioning A: B=1: 3 brushing technology two times, maintain three days.
5, increase the effect of rove false twisting, reduce the misdraft of rove in winding process, ensure that bar solid carbon dioxide is flat.
6, suitably increase roller gauge, reduce the damage of fiber in drafting process.
7, because selected 1.1dtex*38 raw material, so roving twist factor can less than normally be grasped, select 76.
Step is the parameter of the middle fine spining machine adopting 5.: twist multiplier is 780/m, and first break draft multiple is 1.30, and total draft multiple is 16.7, and ingot speed is 12500r/min, and air draught pressure is 3.0kpa.
Spun yarn equipment: (electronics drawing-off drives the RX240E of Toyota, band ring device), adopted have before Special servo motor drive in the electronics drafting system of rear three rollers, on guidance panel, can set every spinning conditions, slub yarn setting means can be selected the mode that front roller slows down or middle roller accelerates, maximum 4 times of ring multiplying power.Can spin freely various slub yarn pattern varieties.
Necked yarn process parameter: slub length 4.5cm, slub space 30～50cm, ring multiplying power 2.2,31 of ring circulation numbers, adopt rear roller speed Control, 226 of ring numbers in 100 meters.
Main experimental parameter:
Spin analysis through preliminary examination, the main quality index that affects viscose glue compact spinning slub yarn is resultant yarn filoplume and brute force, in many yarning process parameters, two technological parameters that the twist and compact spinning negative pressure formula have the greatest impact, therefore we mainly test preferably around these two technological parameters.
Twist contrast test: setting negative pressure is 3.0Kpa, adopts four kinds of different twist spinning, and resultant yarn filoplume and strength test the results are shown in Table 4.
Table 4: different twist resultant yarn filoplumes and strength test result
As can be seen from Table 4, the twist was below or above 780 o'clock, and filoplume all can start obvious increase, and ultimate strength also obviously reduces, and therefore, the twist value of viscose glue compact spinning slub yarn is advisable with 780 sth. made by twisting/m.
Negative pressure contrast test: under twist 780/m condition, adopt 4 kinds of negative pressure to spin, resultant yarn filoplume and strength test the results are shown in Table 5.
Table 5: different negative pressure resultant yarn filoplumes and strength test result
As can be seen from Table 5, when negative pressure is during at 3.0Kpa, viscose glue compact spinning slub yarn filoplume is counted minimum number.Therefore, the negative pressure value of viscose glue compact spinning slub yarn is advisable with 3.0Kpa.
Comprehensive above analysis, for slub length 4.5cm, ring multiplying power 220%, base yarn length 30～50cm, the viscose glue compact spinning slub yarn that average number is 24.0tex, preferably spun yarn main technologic parameters is in table 6.
Table 6: process of roving parameter
Key problem in technology point:
1, increase humidity and be conducive to static and discharge fast, reduce the static producing in fiber and roller friction process, minimizing Yarn filoplume.
2, increase yarn twist factor, improve yarn Dan Qiang, reduce cop filoplume.

4, the adjustment of rove feeding horn mouth pitch-row, is conducive to the drawing-off control of district's fiber of swimming, thus scattering and dropping of fiber and siphoned away and affect bar and do by cotton suction duct while preventing that fiber from exhaling front leather roller.
5, on roller after RC coating (A: B=1: 3, brushing method, maintains three days) antistatic effect is good, avoids, around roller and roller, greatly enhancing productivity.
6, the use of soft elasticity roller, the stability of increase drawing-off, improves the dry CV% value of bar more than 1%.
7, increase the weight of grain traveller, control balloon shape, reduce filoplume.With mine-laying gram C1UL udr1# steel traveler, Yarn filoplume 2mm is 85, more than 2# steel traveler.
8, suitably increase first break draft and nip gauge, be conducive to drawing-off, prevent that " telling hardhead " causes that drawing-off do not open, the broken end head that wafts increases, and is wound around when serious grid ring breakage more.Just having started just has this phenomenon with 1.25 times of first break draft and 2.5 spacing blocks, slightly take a favorable turn after changing spacing block.
9, compact spinning special-shaped tube negative pressure size is carried out to stress test, contrast filoplume and brute force, selection optimum negative pressure is 3.0kpa.
Step winding procedure 6.:
Key problem in technology point:
1, improve workshop humidity to 65-75%, the static producing while reducing groove drum and thread friction, can reduce cylinder yarn filoplume.
2, will particularly pay attention to for the clear technique initialization of the electricity from winder, the additional yarn defect that does not meet slub yarn specification should be removed, but also will check from winder efficiency, hundred pipe broken ends etc., consider composite factor, the large fault that exceeds ring scope must be removed.Path setting relaxes as far as possible, allows Clearing Curve avoid ring region, but classification is set and will be rigid in checking up.
3, groove drum coiling ratio was brought up to 1: 3 by 1: 2, ensured that tube forming is good.
4, suitably improve winding tension, ensure that tube forming is good.
5, drop to 1100m/min from the winder speed of a motor vehicle from 1200m/min, cylinder yarn filoplume obviously improves.
6, stocking yarn will be strengthened Wax enhancement management.
Compact spinning technology adopts aerodynamic principle, pass through compacting element, while making loose fiber yarn after drawing-off by negative tube surface, obvolvent together, through guiding rubber roll output twisting resultant yarn, because twist triangle zone in spinning process becomes very little, substantially disappear, greatly reduce the quantity of the outer fiber exposure that swims, cohesive force between fortifying fibre and fiber, thereby brute force, the especially ultimate strength of ring part of raising slub yarn.
Each equipment of selecting is followed successively by: Truetzschler BO-A2300 griping cotton machine, FD-0/TO-T1 opener, TC5-1 carding machine, FA320 drawing frame, TD03 drawing frame, FA468E Speed frames, RX240E Toyota compact spinning machine (electronics drawing-off band ring device), No.21c village field fully-automatic spooling machine.
