Description
Technical field
The invention belongs to yarn production fields, and in particular to a kind of production method of PBT color spot covering yarn.
Background technique
It is with the development of the times and progressive, pursuit increasingly fashion and personalization of the people to clothes.Color spot covering yarn is just
It is to come into being under such demand.For previous color spot covering yarn mostly using terylene as color spot, 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, not acidproof, chlorine-resistant, dyeing effect be not ideal enough yet.
Summary of the invention
Goal of the invention: in order to keep garment material more lucuriant in design, there is three-dimensional sense, it is color that the present invention provides a kind of PBT
Point covering yarn production method.It is the acrylic fibers idea of different colours is added in the viscous bright and beautiful raw material in part using PBT as heart yarn, then
By special spinning processing so that the colored idea of riot of color is attached on yarn trunk, knitted with what this yarn was worked it out
A kind of idea effect that star is glittering is presented in beyond the region of objective existence sight, embodies the mottled combination missed old times or old friends with modern trend.
Technical solution: a kind of production method of PBT color spot covering yarn includes the following steps:
(1) selection of yarn material:
Color spot: acrylic fibers staple in bulk；Heart yarn: PBT long filament；Outer wrapping fiber: viscous brocade fiber；
(2) process flow of PBT color spot covering yarn
(3) specific production technology
1. acrylic fibers loose stock dyeing:
Concrete operations are as follows: 70 DEG C enter dye, are warming up to 80-85 DEG C with 1 DEG C/min, keep the temperature 15-20min, then with 1 DEG C/
2min is warming up to 100 DEG C, keeps the temperature 40-60min, cool down cylinder out.
2. point processed
Colour idea diameter is about 3~4mm made of acrylic fibers, is in granular form, and any surface finish, knot is of moderate size, grain
Son is very convex, and it is strong to be made coat fabric three-dimensional sense, is suitable for spring and autumn coat or adornment.Idea to ensure to produce has preferable shape
Shape and appropriate outer floating fiber, using first to making technique again after the dyeing of acrylic fibers fibrinogen.Because the yarn of production is mainly used for needle
It knits on large circle machine, otherwise idea small must can can't pass pinprick in weaving process and break end, so using 3 cotton carding points
Process flow.It obtains adequately mutually rubbing knot with the hands by fiber after three cotton cardings, manufactured idea is solid uniformly, in order to prevent rear
The quality that color spot can be loosened in the process in road and staining influences yarn in dyeing course, in proportion with suitable waterproofing agent
It is uniformly sprayed in idea after dilution, drying, high temperature bake.
Process flow: acrylic fiber dyeing → coiled → tri- cotton cardings → spray waterproofing agent → are dried → are baked
Cotton roll is made in Blowing-carding Unit group by common process in colored acrylon fiber, point is rubbed with the hands for carding machine and uses.
The main process apparatus of color spot is A186F carding machine, and the technique for needing to adjust mainly has: widening between cylinder and doffer
Gauge makes doffer lose the effect of transfer fiber, and the fiber on cylinder is rubbed repeatedly under the collective effect of cover board and licker-in
Change into idea.In Process configuration, licker-in not only will point comb after fibre migration 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 the entrance of taker-in grid is fallen by
It is artificial to take out.By manually taking out after being fallen under the action of the centrifugal force between cylinder and doffer there are also the point being partially twisted into.Cover board
With the part of cylinder working face is counter fills, two dial needle teeth of cylinder and cover board are in cross-over configuration, cancel carding role, keep fiber floating
Between two dials.Gauge between cylinder and cover board is 0.50mm or so, increases the rubbing to fiber, to form idea；
Mote knife, spreading and closing taker-in grid are taken out simultaneously, reduce noil amount；Turn off air draught, provides condition for rubbing；Raw material is in cylinder
Rubbing repeatedly between cover board by the long period forms knot, outside at output machine after point.
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 cylinder and Flat Gauge are according to the size appropriate adjustment of required color spot.
3. the carded sliver
It is not both that attached colored cotton knot wherein, and colored cotton knot is cannot to be removed that kinckebocker yarn is maximum with conventional yarn
, the characteristic of this and carding machine is conflict, to ensure that cotton junction impurity is effectively removed in yarn, does color spot less as far as possible
Item, general head are simultaneously arranged in pairs or groups with 1+7, i.e. 1 color spot item, 7 common items.
According to a certain percentage, equably and layering is sprinkling upon in viscous bright and beautiful composite fibre by the idea of shredding.In order to guarantee
Idea is uniformly sprinkled into using layering, is made into color spot volume by cotton cleaning process, is made into the color spot carded sliver, technique stream using carding step
Cheng Shi: color spot and part material mixing → FA002A type cotton feeder → A076E type lapper → A186F type carding machine in advance.It opens
Scutching cotton, which shortens process, can greatly reduce falling for color spot.
The raw materials used viscous bright and beautiful color spot covering yarn of PBT is synthetic fibers and staple fibre, and cotton junction impurity is seldom, therefore cotton carding work
The main technique requirement of sequence are as follows: ensure that color spot falls less or do not fall；Ensure to comb to have exposing appropriate fine again color spot fanout free region
Dimension.
A point comb gauge between cover board and cylinder generally uses not loose not tight technological principle.Stronger carding role is not only
It has color cotton to become smaller greatly, there is also comb power may be divided excessive, a possibility that carding assembly single-fiber that color spot is complete, this is not only
How much influence color spot, while will cause dyed yarn background color and changing to form interference.Although crossing a weak point comb not injure color spot,
But other fibers, because of point bad unwanted heterochromatic cotton knot easy to form of comb, this is the emphasis that kinckebocker yarn needs to take precautions against.
Color spot cotton carding main technologic parameters: cylinder speed 330-600r/min, licker-in revolving speed 700-900r/min, doffer
Revolving 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 wants smooth, bright and clean and sharp keen simultaneously, and otherwise fiber cannot
It successfully shifts and strips；Weight of card sliver grasp suitably bigger than normal, general control is in 23~26g/5m or so, because having in web
Knot exists, and the cohesive force between them is smaller, and weight of card sliver grasp bigger than normal is conducive to improve cohesive force；To prevent cotton net from shaping
Difficulty, using cross apron web-collecting system；
Requirement etc. in practice according to status of equipment, raw material condition and rear road to color spot form adjusts accordingly, special
It is not the number and size that cylinder-Flat Gauge directly determines color spot, has controlled cloth style.
The spinning of the conventional carded sliver: A002C type griping cotton machine → A035 type mixed cotton slitter → FA106B type opener → FA046A
Type cotton feeder → A076F type lapper → FA201B type carding machine.
4. mixing in doubling step
Head is simultaneously mixed simultaneously using+1 point item of 7 conventional strips.Two, 38 and close technique it is suitable, by increasing and closing
Radical reinforces idea and obtains the effect of full and uniform distribution in item, while it is dry to be conducive to improvement item.It is noted that point item and routine
The uniform collocation of item arranges, and can be uniformly dispersed idea.The total draft of each road drafting is preferably controlled at 8.5 times or less.To prevent out
Item blocking broken end, horn mouth answer control bigger than normal.Mixing in doubling step mainly improves straightening of fibers, depth of parallelism etc., therefore selects suitably
Technique road number and number of doubling are most important.Slubbing is carried out respectively and is closed to the carded sliver and the idea carded sliver, due to feeding the life of head drafting
Fiber alignment disorder, preceding crotch is in the majority, and in order to preferably stretch preceding crotch, head and back area draft answers control bigger than normal is used
1.746 times, 1.018 times of middle area, primary area drawing-off is 3.938 times, and the Unevenness CV of color head drafting is 3.5% at this time, the item of idea item
Dry CV is 3.9%.Crotch is more after head drafting, in order to effectively improve this situation and idea be allowed to have stronger three-dimensional sense, using two
And technique.Two and back area draft use 1.15 times, Unevenness CV 3.0%.During production, the bright and clean of channel is kept,
And head and idea item and two drafting horn mouths answer control bigger than normal, and speed is decreased slightly as low, can reduce that broken end, to improve item dry.It leads back zone
Multiple 1.630,46 × 46mm of ratch are stretched, pressure bar adjusts ring diameter 12mm.
5. Roving Frames
Roving Frames answer reasonable disposition draft area technological parameter, using low speed, the technique of big twist factor, small back area draft
Principle gives full play to primary area drawing-off effect, is conducive to control floating fiber, improves yarn quality.In the feelings of spun yarn not harmful drafting
Under condition, twist factor control bigger than normal, in this way can by color spot, effectively looping is not easy to fall in the yarn, while adjust front and rear row
Power difference, effectively improves yarn quality.
The main technologic parameters of rove are as follows: quantitative 7g/10m, 1.1-1.21 times of back area draft, is twisted by 5-7.2 times of drafting multiple
Coefficient 100-120, roller gauge are 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 cotton net
It is raw；Prevent away monofilament and scarce silk；The wire loop period wants short.
The main technologic parameters of spun yarn are as follows: regular roving feeding: 8g/10m, yarn number: 21tex, back area draft ratio: 1.15-
1.200 times, spindle revolving 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, accumulation color spot are removed under the premise of guaranteeing that normal color spot is not cut accidentally.Control is moved back
Around speed, prevents Yarn filoplume from excessively increasing and form yarn and be adhered, influence later process weaving.Photo-electric electronics should generally be selected
Yarn clearer, winder speed 1000-1200m/min, yarn clearer parameter: cotton knot+450%, short slub+200% × 1.8cm long slubbing
+ 32% × 45cm, long -32% × 45cm of details.
The utility model has the advantages that specific advantage of the invention is as follows:
1, the present invention uses raw material of the acrylic fibers as idea, and color spot various colors, color is more gorgeous, and three-dimensional sense is strong, valence
Lattice are more per ton than common polyamide fibre idea can to save 20,000 yuan.
