Description
Technical field
The invention belongs to yarn production field, and in particular to a kind of production method of PBT coloured silks point covering yarn.
Background technology
With the development and progress in epoch, pursuit increasingly fashion and personalization of the people to clothes.Coloured silk point covering yarn is just
It is to be arisen at the historic moment under such demand.Conventional color point covering yarn is more using terylene as color point, and spandex filament is heart yarn, outsourcing
The fibers such as cotton, fiber crops, such covering yarn color is not gorgeous enough, and bulkiness is poor, and not acidproof, not chlorine-resistant, Color is also not ideal enough.
The content of the invention
Goal of the invention：In order that garment material is more lucuriant in design, it is color the invention provides a kind of PBT with third dimension
Point covering yarn production method.It is, using PBT as heart yarn, the acrylic fibers idea of different colours to be added in the viscous bright and beautiful raw material in part, then
By special spinning processing the colored idea of riot of color is attached on yarn trunk, with knitting that this yarn is worked it out
Beyond the region of objective existence, which is seen, is presented a kind of glittering idea effect of star, embodies the mottled combination missed old times or old friends with modern trend.
Technical scheme：A kind of production method of PBT coloured silks point covering yarn, comprises the following steps：
(1) selection of yarn material：
Color point：Acrylic fibers staple in bulk；Heart yarn:PBT long filaments；Outer wrapping fiber：Viscous brocade fiber；
(2) technological process of PBT coloured silks point covering yarn
(3) specific production technology
1. acrylic fibers loose stock dyeing：
Concrete operations are as follows：70 DEG C enter dye, and 80-85 DEG C is warming up to 1 DEG C/min, are incubated 15-20min, then with 1 DEG C/
2min is warming up to 100 DEG C, is incubated 40-60min, cools and cylinder.
2. point processed
The colored idea diameter that acrylic fibers are made is about 3~4mm, is in granular form, any surface finish, knot is of moderate size, grain
Son is very convex, coat fabric third dimension is made strong, it is adaptable to spring and autumn coat or adornment.To ensure that the idea produced has preferable shape
Shape and appropriate outer floating fiber, using first to making a technique again after the dyeing of acrylic fibers fibrillation.Because the yarn of production is mainly used in pin
Knit on large circle machine, otherwise idea small must can can't pass pinprick in weaving process and break end, so using 3 road cotton carding points
Technological process.Obtain sufficiently mutually rubbing knot with the hands by fiber after three road cotton cardings, the idea being made is solid uniform, in order to prevent rear
The process in road prize a meeting be loosened and in dyeing course staining influence yarn quality, with suitable waterproofing agent in proportion
Uniformly it is sprayed at after dilution in idea, drying, high temperature are baked.
Technological process：The road cotton carding → spray waterproofing agent → of acrylic fiber dyeing → coiled → tri- is dried → baked
By common process in Blowing-carding Unit group lap is made in colored acrylon fiber, rubbing point with the hands for carding machine uses.
The main process apparatus of coloured silk point is A186F carding machines, it is necessary to which the technique of adjustment mainly has：Widen between cylinder and doffer
Gauge, makes doffer lose the fiber on the effect of transfer fiber, cylinder under the collective effect of cover plate and licker-in, is rubbed repeatedly
Change into idea.In Process configuration, licker-in is not only by the fibre migration after point comb to cylinder, while also cylinder dial
The knot of afterturn is peeled back to again, the idea that has been twisted into of part under the action of the centrifugal force, after being fallen at the import of taker-in grid by
It is artificial to take out.The point being also partly twisted into fallen under the action of the centrifugal force between cylinder and doffer after by manually taking out.Cover plate
With the part of cylinder working face is counter fills, two dial pin teeth of cylinder and cover plate are in cross-over configuration, cancel carding role, float fiber
Between two dials.Gauge between cylinder and cover plate is 0.50mm or so, and increase is rubbed fiber, to form idea；
Mote knife, spreading and closing taker-in grid are taken out simultaneously, reduce noil amount；Turn off air draught, to rub offer condition；Raw material is in cylinder
Rubbed to form knot repeatedly by the long period between cover plate, be easy into after point outside output machine.
The related process configuration of system point carding machine：Cylinder speed 300-500r/min；Licker-in speed 700-750r/min；Lid
Plate speed 0；Doffer speed 20-40r/min；Feed plate-licker-in gauge 0.28-0.31mm；Cylinder-Flat Gauge 0.33-
0.45mm、0.28-0.45mm、0.25-0.5mm、0.25-0.5mm、0.28-0.45mm；Cylinder-doffer is every 0.10-0.150mm.
Wherein the size of color point needed for is suitably adjusted cylinder with Flat Gauge.
3. the carded sliver
Kinckebocker yarn and conventional yarn maximum are not both that addition of colored cotton knot wherein, and colored cotton knot is to be eliminated
, the characteristic of this and carding machine is conflict, to ensure that cotton junction impurity is effectively eliminated in yarn, does color point less as far as possible
Bar, general head is simultaneously arranged in pairs or groups with 1+7, i.e., 1 color point bar, 7 common bars.
According to certain ratio, by the idea of shredding equably and layering is sprinkling upon in viscous bright and beautiful composite fibre.In order to ensure
Idea is uniformly sprinkled into using layering, is made color point by cotton cleaning process and is rolled up, then makes color the point carded sliver, technique stream by carding step
Cheng Shi：Coloured silk point and part material mix → FA002A types cotton feeder → A076E types lapper → A186F type carding machines in advance.Open
Scutching cotton, which shortens flow, can greatly reduce dropping for color point.
It is synthetic fibers and staple fibre that the viscous bright and beautiful coloured silks of PBT, which put covering yarn raw materials used, and cotton junction impurity is seldom, therefore cotton carding work
The main technique of sequence is required：Ensure that color point falls or do not fallen less；Ensure to comb to coloured silk point fanout free region, have appropriate expose fibre again
Dimension.
A point comb gauge between cover plate and cylinder typically uses not loose not tight technological principle.Stronger carding role is not only
Have color cotton to diminish greatly, also presence may divide comb power excessive, by the color possibility for putting complete carding assembly single-fiber, this is not only
How much is the color point of influence, while dyed yarn background color can be caused to change to form interference.Although crossing weak point comb not injure coloured silk point,
But other fibers are because dividing comb is bad easily to form unwanted heterochromatic cotton knot, this is the emphasis that kinckebocker yarn needs to take precautions against.
Coloured silk point bar cotton carding main technologic parameters：Cylinder speed 330-600r/min, licker-in rotating speed 700-900r/min, doffer
Rotating speed 21-40r/min, 78~80mm/min of cover plate speed, cylinder-doffer gauge 0.10-0.15mm, feed plate-licker-in gauge
0.15-0.20mm, cylinder-Flat Gauge be 0.3-0.40mm, 0.25-0.40mm, 0.25-0.38mm, 0.25-0.38mm,
0.28-0.40mm.In addition, flat strips wants timely reuse；Carding element is smooth, bright and clean and sharp keen simultaneously, and otherwise fiber can not
Successfully shift and strip；The appropriate grasp bigger than normal of weight of card sliver, general control is in 23~26g/5m or so, because having in web
Knot is present, and the cohesive force between them is smaller, and weight of card sliver grasp bigger than normal is conducive to improving cohesive force；To prevent web from shaping
Difficulty, using cross apron web-collecting system；
Corresponding adjustment is made to color requirement for putting form etc. according to status of equipment, raw material condition and rear road in practice, it is special
Be not cylinder-Flat Gauge directly determine color point number and size, left and right cloth style.
The spinning of the conventional carded sliver：A002C types griping cotton machine → A035 types mixed cotton slitter → FA106B types opener → FA046A
Type cotton feeder → A076F types lapper → FA201B type carding machines.
4. mixing in doubling step
Head is simultaneously mixed simultaneously using+1 point bar of 7 conventional strips.The technique in two roads, 8, three road and conjunction is suitable, by increasing and closing
Radical, strengthens idea and the effect of full and uniform distribution is obtained in bar, while being conducive to improvement bar to do.It is noted that point bar and routine
The uniform collocation arrangement of bar, can be uniformly dispersed idea.The total draft of each road drafting is preferably controlled below 8.5 times.To prevent out
Bar blocks broken end, and horn mouth answers control bigger than normal.Mixing in doubling step is mainly improvement straightening of fibers, depth of parallelism etc., therefore selection is suitable
Technique road number and number of doubling are most important.Slubbing is carried out and closed to the carded sliver and the idea carded sliver respectively, due to feeding the life of head drafting
Bar fiber alignment is disorderly, and preceding crotch is in the majority, and in order to preferably stretch preceding crotch, simultaneously back area draft answers control bigger than normal to head, uses
1.746 times, middle 1.018 times of area, primary area drawing-off is 3.938 times, and now the Unevenness CV of color head drafting is 3.5%, the bar of idea bar
Dry CV is 3.9%.Crotch is more after head drafting, in order to effectively improve this situation and allow idea to have stronger third dimension, using two
And technique.Two and back area draft use 1.15 times, Unevenness CV is 3.0%.During production, the bright and clean of passage is kept,
And head and idea bar and two drafting horn mouths answer control bigger than normal, speed is decreased slightly as low, can reduce broken end, to improve bar dry.Lead back zone
Stretch multiple 1.630,46 × 46mm of ratch, pressure bar regulation ring diameter 12mm.
5. Roving Frames
Roving Frames answer reasonable disposition draw zone technological parameter, using low speed, big twist factor, small back area draft technique
Principle, gives full play to primary area drawing-off effect, is conducive to controlling floating fiber, improves yarn quality.In the feelings of spun yarn not harmful drafting
Under condition, coloured silk can so be put effectively looping and be difficult to fall in the yarn, while adjusting of front and rear row by twist factor control bigger than normal
Power difference, effectively improves yarn quality.
The main technologic parameters of rove are：Quantitative 7g/10m, 5-7.2 times of drafting multiple, 1.1-1.21 times of back area draft is twisted with the fingers
Coefficient 100-120, roller gauge is 11.5mm × 22mm × 26mm, and rove elongation control is within 1.5%.
6. spinning process
The important requirement of spinning process：Core filaments running check godet roller position and will be defended in the centre of front draft zone web
It is raw；Prevent away monofilament and scarce silk；The wire loop cycle is short.
The main technologic parameters of spun yarn are：Regular roving feeding：8g/10m, yarn number：21tex, back area draft ratio：1.15-
1.200 times, spindle rotating speed：5000-9000 turns/min, yarn twist factor：250-270, heart yarn pre-draft multiple：1.0-1.05
Times.
7. winding procedure
Harmful Defect, such as short slub, the color point of accumulation are removed on the premise of ensure that normal color point is not cut by mistake.Control is moved back
Around speed, prevent Yarn filoplume excessively increases from forming yarn and be adhered, influence later process weaving.Photo-electric electronics should typically be selected
Yarn clearer, winder speed 1000-1200m/min, yarn clearer parameter：Cotton knot+450%, the long slubbings of short slub+200% × 1.8cm
+ 32% × 45cm, long details -32% × 45cm.
Beneficial effect：The specific advantage of the present invention is as follows：
