(2) optimization of spinning process is spinned using digital spinning machine, when spinning to back zone drafting multiple, twist factor, Ingot speed carries out preferably, keeping institute's yarn colour mixture uniform, and web surface color has stereovision.
Specific embodiment
It elaborates below with reference to embodiment to specific embodiment provided by the invention.
Concrete technology flow process:
Yarn production: it grabs cotton → mixing → shredding → coiled → combing → pre-drawing, item and roll up → combing → drafting (2) → thick Yarn (three kinds of colors) → spun yarn (the blended digital yarn of polychrome)；
Fabric production: the blended digital yarn → doubling → rewinding → of polychrome knit piece → running-on → flatcar → hand seam → washing → drying → It is whole to scald → packaging → storage.
(1) design of yarn
It is well arranged to make fabric that there are various colors, the features such as three-dimensional sense and strong fashion, select three kinds of colors of red, blue, yellow Color is used with substantially for yarn, while selecting cotton fiber is raw material, so that fabric be made to have, softness, pro-skin, moisture adsorption and releasing are good takes Performance.
Since certain space multistory effect can be showed when different colours fiber is mutually mixed resultant yarn in spinning process, have Necessity carries out blended fiber ratio example preferred.Range is matched to reduce color, choosing darkviolet is basic tone, and devises face Color mixed ratio are as follows: red 60%/indigo plant 20%/Huang 20%.
(2) Spinning Process Design
Yarn spinning in, using can independent control feeding roving-drafting ratio digital spinning machine, i.e., directly select red, Lan Hehuang The rove item of three kinds of colors carries out direct spinning.Back zone drafting multiple, twist factor, ingot speed preferably, finally set when spinning Determining back zone drafting multiple is 1.2, and twist factor range is 320 ~ 340, ingot speed 9000r/min.To reduce fiber incomplete mixing, Yarn qualities are further increased, introduce compact spinning apparatus in twist triangle zone.
The fiber as used in fiber dyed yarn is all by stock-dye and then to pass through spinning line, and fiber contaminates Color has certain damage to the physical mechanical property of fiber, in response to this, the setting of the technique of the spinning each process of colour-spun yarns with Common white yarn has certain difference.Fiber dyed yarn product is usually all towards middle and high-end market, so raw material is distributed cotton Common yarn of the grade usually than identical yarn count is slightly higher, to make up stock-dye to fibre damage, caused by coloured fibre can spin Property decline and physical property decline.
Fore processing optimum:
Color fibre → opening picking → cotton carding → pre-drawing, item simultaneously roll up → combing → drafting (2).
Spinning is a system engineering, and opening picking is the starting point of cotton spinning engineering, is the key that determine cotton spinning engineering quality work One of sequence.Blow room system should make every effort to scientific and reasonable, carry out production by best process and process conditions.
It is dyed using raw cotton, since cotton fiber shredding is not enough, the cotton fiber that same dye vat is contaminated has certain color Difference, meanwhile, it is poor also there is certain cylinder by the fiber that different dye vats dye.In grabbing cotton process, row's packet of color fibre is mixed Conjunction also needs to pay attention to, to solve color difference, improve the uniformity.Related coloured fibre performance is as shown in table 1.
1. coloured fibre performance indicator of table
Color category Mic value Upper half mean length/mm Length uniformity/% Short fiber content Breaking strength/gf/tex
It is red 3.97 28.06 82.50 13.01 29.50
It is yellow 3.67 28.47 82.50 12.58 28.90
It is blue 4.05 28.25 82.20 12.68 29.10
Raw cotton is after dyeing, fiber physical property decline, in opening processes, should follow " acute after first delaying, progressive shredding ", reach To the effect of few damage fiber.Dedoping step is close with common white yarn process is spun, and using the technique of caducous impurity, exists to prevent impurity It is crushed in process, it is more difficult to remove.In order to guarantee being sufficiently mixed and uniformly conveying for color fibre, accomplish to stablize supply, Two hoppers (cotton feeder) are configured in opening picking process.Coloured fibre by dyeing and washing, in fiber impurities under It drops, in blow room system used, 3 opening or cleanings points is configured, usually using opener and scutcher hired roughneck as opening or cleaning point.
The configuration of opening picking board:
FA002(2 platform) → FA121 → FA104 → FA022 → FA106 → A062 → A092AST → FA141
Fiber declines by dyeing, physical mechanical property, and in opening and cleaning step, opener Beater Speed is suitably reduced, and can subtract Few fibre damage reduces cotton knot incrementss, and each dirt stick spacing of opener is by cotton flow from entrance to outlet by reducing greatly.Due to color fibre Higher cost, opening picking and carding step are tieed up, on the basis of improving single machine removal of impurities efficiency, suitably reduces linters rate.Linters rate Control the 70-75% in raw cotton percentage of impurity.
Short flannel is more readily formed with respect to raw cotton in carding step in coloured fibre, and carding machine licker-in speed suitably reduces, and reduces Pre- carding role is held, fibre damage is reduced.Meanwhile cylinder speed can keep speed identical as common white yarn, cylinder speed Reduction can reduce the needle point number acted on fiber in the unit time, reduce combing effect, and reduction cylinder speed can make, cylinder A point comb load improve, fiber is easy to rub with the hands on dial then forms cotton knot, and cylinder speed reduction is also unfavorable for impurities removal.
Comb preparation procedure uses: pre-drawing (6) → item simultaneously rolls up (28)
Using this technique, cotton roll lateral comparison is uniform, and fiber has certain diffusion, and rouleau quantitatively weighs, and can improve combing machine yield, together When be conducive to remove short flannel.
Process of roving configuration:
Since spun spun yarn number is lower, spinning frame has stronger drawing-off ability, so roving-drafting grasp less than normal, rove are fixed Amount is appropriate to be chosen, and roving twist factor grasp less than normal is conducive to improve roving yarn quality, can also save rove board.
Spinning process configuration:
Gradual change yarn is produced in spinning process, the drafting multiple in three drawing-off channels differs greatly, and total draft multiple and back zone are led It is very big to stretch multiple span, needs to integrate each factor and formulates technique, it is more demanding to spinning process.
First break draft area technique: since each channel back zone drafting multiple differs greatly, and variation range is larger, and back zone needs to hold Biggish drawing-off is carried on a shoulder pole, the roving twist in first break draft area is higher, and the cohesive force between fiber is larger, needs suitably to increase first break draft Area's ratch, in setting, rear roller center is away from for 65mm.
Total draft multiple and back zone drafting multiple variation range are all larger, roller loading grasp bigger than normal, before being set as, in, Pressurize the bis- ingots of 180*120*140N/ afterwards.Apron uses elastic nip, comprehensively considers fibre weight in draft area, low in drafting multiple, When fibre weight is big, it is unable to harmful drafting, in drafting multiple height, fibre weight hour again effectively controls fiber, apron nip gauge Moderate grasp, using 3.0 spacing blocks.
(3) straight-bar machines technique
In face weave, first yarn is lubricated and upper Lasaxing Oilfield is avoided with improving the smoothness of yarn in weaving process , there are the flaws such as broken hole so as to cause fabric in broken yarn caused by the middle knotting because of yarn.
Use fabric tissue for single side plain.It is horizontal close: 61.5/10cm；It indulges close: 40.3/10cm.Needle number: 12G, in computer Fabric on flat knitting machine.Yarn: 30 are usedS/ 2 strands.Grammes per square metre: 293 grams/m.Gained fabric hand feel softness is well-pressed, and color is rich Richness, layer variability is distinct, has stronger three-dimensional sense.
