Abstract
The invention relates to a dyeing method of rough yarn used for purified cotton. The dyeing method of the rough yarn is characterized by comprising the following working procedures of preparing raw cotton, cleaning the cotton, carding the cotton, performing pre-drawing, forming laps from slivers, performing combing, performing drawing, performing roving, rewinding rough yarn to a loose-type winder, performing dyeing and drying, spinning the yarn and performing spooling, wherein in the roving procedure, the twist multiplier of the rough yarn is 1.05-1.08 times that of normal purified cotton rough yarn; the procedure of rewinding the rough yarn to the loose-type winder is performed on FIDS spooling equipment with the model number being SINCRO/RFM-FC-RC P400A, on the FIDS spooling equipment, the purified cotton rough yarn is wound around a loose-type tube for dyeing through an automatic backing-off device; a roving tube is sleeved with the loose-type tube with the dyed and dried rough yarn, spinning can be performed as long as the loose-type tube with the dyed and dried tough yarn is directly hung on a spinning frame, and then the dyed purified cotton rough yarn can be manufactured. According to the dyeing method of the rough yarn, the defects that after being dyed, cotton is poor in spinning suitability and low in yarn strength and has much nep irregular fuzz and many neps are overcome, yarn quality is guaranteed, besides, the technological process is short, in this way, energy consumption can be lowered, and the effects of saving energy and reducing emissions are remarkable.
Description
Technical field
The present invention relates to a kind of cotton textiles rove colouring method, belong to textile technology field.
Background technology
Cotton fiber is the main raw material of China's textile industry, and pure cotton fabric relies on the features such as its softness, next to the skin, comfortable, ventilative, antistatic, is the cloth textile of people's first-selection, accounts for very consequence in weaving.The relative dyeing fabric of pure cotton yarn-dyed fabric, its unique style, but due to the yarn dyeing of yarn-dyed fabric, weave, the total losses of rear arrangement are larger, platform produces also high not as good as the output of grey cloth, so cost also strengthens relatively.Traditional look is knitted with yarn production procedure technique process many and complicated, be specially raw cotton → blowing → comb and parallel cotton fibers prior to spinning → pre-drawing → bar volume → combing → drafting → rove → spun yarn → winder → loose type coning → dyeing oven dry → compact form winder, because rewinding before and after dyeing has not only increased process energy consumption, reduced yarn strength, increase filoplume, greatly reduce yarn quality, and reduced raw material availability.Just need at present a kind of look that can reduce energy consumption, raising raw material availability and yarn strength to knit and use yarn production method, there is not yet, also in data, do not inquire.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provides a kind of and can reduce energy consumption, enhances productivity and raw material availability and guarantee a kind of cotton textiles rove colouring method of yarn quality.Its technical scheme is:
A kind of method of rove dyeing for cotton textiles, it is characterized in that adopting following operation: raw cotton → blowing → comb and parallel cotton fibers prior to spinning → pre-drawing → bar volume → combing → drafting → rove → rove fall loose formula cylinder yarn → dyeing oven dry → spun yarn → winder, wherein in Roving Frames, roving twist factor is 1.05～1.08 times of normal textile roving twist factor, it is to carry out on model is the FIDS Spooling oquipment of SINCRO/RFM-FC-RC P400A that rove falls loose formula cylinder yarn operation, automatic unwinding device will be passed through on textile rove FIDS Spooling oquipment, by reeling roving on Song Shiguan, rove is dyeed, rove pine formula pipe box after dyeing is dried, on flyer bobbin, directly hangs on fine spining machine and can spin, and can make the textile rove yarn of dyeing.
The method of rove dyeing for described a kind of cotton textiles, rove falls in loose formula cylinder yarn operation, and loose formula rove density is 0.36---0.42g/cm
3.
Compared with prior art, its advantage is in the present invention:
1, due to fibre cohesion variation after rove dyeing, easily cause disconnected rove phenomenon, therefore strengthen roving twist factor, and rove is encased with the stocking leg, the rove of loose formula is directly first dyeed and spinned afterwards, can make the inside and outside solid colour of yarn, gloss is soft, and colour stability is relatively good.
2,, due to regular roving feeding weight, output, rove pine formula rewinding, far away higher than the loose formula rewinding of cylinder yarn, and can be produced in batches, make thus look knit more and simplify, not only greatly saved production cost, also reduced production link, guaranteed yarn quality, it is simple changing complexity.
3, due to what adopt, be first to dye afterwards and spin, the shortcoming such as solved spinning suiting ability after cotton dyeing, yarn strength is low, filoplume is many, cotton knot is many, has guaranteed yarn qualities.
The specific embodiment
Below in conjunction with embodiment, the present invention will be further described.
Example one: cotton is selected 100% U.S.'s pima cotton, technological process is still that raw cotton → blowing → comb and parallel cotton fibers prior to spinning → pre-drawing → bar volume → combing → drafting → rove → rove fall loose formula cylinder yarn → dyeing oven dry → spun yarn → winder.Regular roving feeding 1.6g/10 rice wherein, twist with the fingers/inch of the twist 2.1, twist factor 104; It is in Italy, to produce, carry out on FIDS Spooling oquipment that model is SINCRO/RFM-FC-RC P400A that rove falls loose formula cylinder yarn operation: 150 ms/min of the speed of a motor vehicle, tension force 6.5N, traverse 270mm, density 0.38g/cm
3; Spun yarn: white, yellow two kinds of color rove are arranged in pairs or groups mutually, use the spinning of match network, 180 match networks of yarn count spin, 13500 revs/min of compact spinning spun yarn spindle speeds, twist with the fingers/inch of the twist 37.
The detection data of gained yarn of the present invention and existing technique gained yarn are as follows:
Example two: cotton is selected 100% U.S.'s pima cotton, technological process is still that raw cotton → blowing → comb and parallel cotton fibers prior to spinning → pre-drawing → bar volume → combing → drafting → rove → rove fall loose formula cylinder yarn → dyeing oven dry → spun yarn → winder.Regular roving feeding 6.2g/10 rice wherein, twist with the fingers/inch of the twist 2.1, twist factor 104; It is in Italy, to produce, carry out on FIDS Spooling oquipment that model is SINCRO/RFM-FC-RC P400A that rove falls loose formula cylinder yarn operation: 100 ms/min of the speed of a motor vehicle, tension force 6.5N, traverse 270mm, density 0.38g/cm
3; Spun yarn: yarn count is set as 40 English and props up, 14500 revs/min of compact spinning spun yarn spindle speeds, twist with the fingers/inch of the twist 25.5.
The detection data of gained yarn of the present invention and existing technique gained yarn are as follows:
From above yarn, detect recently, the yarn of gained of the present invention is better than traditional handicraft at aspects such as intensity, cotton knot, filoplumes, and technological process is short, and energy-saving consumption-reducing is obvious.
