Concrete technology step of the present invention is:
1) preliminary treatment of Chinese fiber crops
According to the doubling rate of fiber and the content of runner fault and the fineness of fiber, the licker-in release through 1 to 2 time is needed to the flax fibre of crudy difference, with single licker-in flicking machine or play carding willow and carry out shredding process.
2) Chinese fiber crops humidification and steam numb health process
Because the spinnability of of china-hemp fibers itself is poor, and containing higher lignin in fiber, for improving spinnability, fiber process factory all will carry out necessary oiling moisturizing before Chinese fiber crops become to contract out factory, we are the flexibility improving fiber further, general employing two kinds of humidification Curing Methods.One is with humidifier humidifies process or spray steam moisturizing vexed putting makes the moisture regain of fiber about 12% at least 24 hours, and two is take to steam fiber crops process, and steaming numb technique is the period 1 62 DEG C, insulation 15min, vacuum 300mbar, second round 75 DEG C, insulation 25min, vacuum 450mbar.We to batch larger kind generally take to steam numb technique, steam fiber crops after fiber more softness closer to the spinnability of cotton.
3) Chinese fiber crops premix and mixed cotton
Necessary mixture cotton all will be carried out for Chinese fiber crops and the combed yarn of cotton blending, yarn quality is guaranteed while reduction spinning cost, mixing generally takes the bale of cotton to mix, adopt and carry out a premixed for making to mix us in advance with an A002D automatic plucker, then mix further at cotton cleaning process again through the packing of A771A baling press.And in the noil of comb and parallel cotton fibers prior to spinning and combing, the content of flax fibre is higher, suitably improves the ratio of flax fibre, generally improve 5-10% when therefore distributing cotton.
4) cotton cleaning process, pipeline modification, hired roughneck's reduction of speed, reduction rolling tension force, raising workshop humidity
Cotton cleaning process is shredding, removal of impurities, mixing rolling, Chinese hemp spinning yarn or cotton ramie blended spinning cotton cleaning process are through A002D automatic plucker → A035 mixed cotton slitter → FA025 multi-mixer → FA106 opener → A092AST vibrating cotton box cotton feeding → A076E single beater scutcher, for reducing the damage of fiber, reduce the speed of each hired roughneck, change porcupine hired roughneck into kirschner beater; Functional fibre spinning cotton cleaning process is through A002D automatic plucker → FA106 opener → A006B cotton blender machine → A092AST vibrating cotton box cotton feeding → A076E single beater scutcher, to the transformation of functional fibre by pipeline, change a road into and directly skip A035 mixed cotton slitter, FA025 multi-mixer, air exercise hand strap wheel is transformed, make the Beater Speed of FA106 opener reduce to 385-420r/min by 480r/min, comprehensive Beater Speed reduces to 750-850r/min; Hired roughneck's dirt rod is closed, reduces the rate that falls; For ensureing that the relative humidity of lap moisture regain cotton cleaning process controls at 68-73%, above griping cotton machine, humidifier is installed simultaneously; For reducing the cotton layer tension force of lapper, avoiding cotton layer to break, changing the gear of rolling roller into 38 teeth by 37 teeth, time tension draft reduce 2.5%.
5) carding step, reasonable selection pin cloth, adjusting process space, transform roller transmission, use apron stripping, guarantee that slivering is fluffy, dust filtering fan strengthens;
Carding step is combing mixing and the doubling of removal part and runner, heighten the rate of transform of fiber, the speed ratio of cylinder licker-in is 2.2, the cylinder speed 360r/min of adjustment cotton fiber, the cylinder speed 330r/min of adjustment functional fibre, cylinder flat spaces 12,11,10,10,11(1/1000 "); very the cylinder of cotton ramie blended spinning does not adopt and spins cotton Bearded-needle knitted cloth; be AC2030*1540 type; the functional fibre Bearded-needle knitted cloth spinning chemical fibre; adopt AC2525*1850 type, MCZH28 type selected by flat-clothing; The rate controlling 7-8% that always falls of carding step; For ensureing that junk siphons away in time, changing original dust filtering fan into 30kw by 22KW, improving filter dirt air quantity;
Tension draft for pure Chinese fiber crops or the higher yarn comb and parallel cotton fibers prior to spinning of the numb ratio of the Chinese is little, and change the travelling gear of feed roll motor into 22 teeth by 21 teeth, reduce 4.5% to cotton sheet power, be ensure slivering, comb and parallel cotton fibers prior to spinning adopts apron stripping.
6) pre-drawing volume operation, improves combined roots, transformation draft gear, reduces total draft multiple, reduces rolling speed, adjusts tension force everywhere;
Pre-also operation mainly improves combined roots to functional fibre, reduces weight unevenness.Generally take 8 and close, larger first break draft, reducing total draft multiple, to reduce the numb grain of combing as far as possible.
Bar is also rolled up operation and also will be reduced total draft multiple, the total draft change gear that we also roll up E32 bar has simultaneously carried out transforming making total draft multiple reduce to 1.43 times by 1.56 times, because the cohesive force of ramie stripes is poor, the slippage drawing-off of easy generation fiber, therefore drawing-off is everywhere little, and it is smooth to close table top, rolling speed is not more than 80m/min.
7) combing process, transforms dust-filtering system, guarantees that junk is separated, change cylinder tooth is close, guarantees abundant combing
Combing process mainly gets rid of staple fibre, guarantees the short fiber content of sliver, and the rate general control that falls of combing is at 16-18%, and the kind linters rate higher to Chinese fiber crops ratio also wants large, controls at 18-25%; Reduce the tension draft of combing table top and the tension draft of feeding from lap, boundling bell mouth suitably strengthens.
For spin simultaneously cotton textiles and the Chinese fiber crops blending kind time, junk to be carried out and be separated completely, will transforming the filter dirt of combing of same combing dust-filtering system is shared for two kinds, original combing filter dirt has been added again one-level disc filtration device at inlet box place by us, and improve the rotating speed of disk suction nozzle, ensure normally to inhale noil.
Be difficult to enter drafting system after carding because of it for pure Chinese fiber crops kind, sliver is very easily pulled off.Therefore the product of pure Chinese fiber crops is preferably adopted to the combing machine of domestic A201 type.The tooth strengthening cylinder is close, and more than ensureing that cylinder density is red 35000, top comb insertion depth 0.2mm, carding isolation distance 0.3mm, ensure web quality.
8) and unskilled workman's sequence, roller special treatment, speed variable frequency control, the twist suitably improve
And unskilled workman's sequence will carry out special treatment to roller, the lacquer coating of black is generally taked to process, reduce total draft multiple, rove will reduce tension force as far as possible, and ingot speed suitably lowers, generally be no more than 650r/min, the part board of mixing in doubling step we change frequency control into by belt wheel speed governing, according to the characteristic of the easy moisture absorption of flax fibre, control well and the relative humidity of unskilled workman's sequence, generally control by 65-70%, humidifier will be installed if desired.The speed of drafting will reduce, and is generally less than 150m/min.The package of rove is little, and the twist factor of rove generally improves about 20% than cotton.
9) spinning process, ingot prompt drop is low, transformation suction negative pressure, add high draft and space, improve into twist per unit, the process of roller coating;
The ingot speed of spinning process will reduce, and is no more than 8000r/min to pure numb kind, the kind ingot speed improvement value 10000-12000r/min of low; The twist factor of spun yarn designs by 400-450, suitably strengthens roller gauge, 4-6mm larger than cotton, adopts larger spacing block to avoid harmful drafting; Improve the frequency of the negative-pressure air fan of compact spinning for press more than 60HZ, negative-pressure air fan is changed if desired, with rarer tightening weave net ring, the blower fan of suction tube also will strengthen, reduce spinning end breaking, the cast that the steel traveler yarn path of spun yarn is wide, can the steel traveler of 6903 or 6802 types, and rings adopts bearing steel rings.
For avoiding flax fibre to be mixed into other yarns, reducing three, isolation will be carried out with textile kind to Chinese fiber crops kind.
10) winder thresholding adjustment, speed suitably reduce, guarantee sth. made by twisting knot quality, increase pneumatics board
