Abstract
The invention provides a method for producing high-density combed cashmere yarns or cashmere blended yarns. The method needs production of carrier PVA (polyvinyl acetate) soluble fibers and includes the steps of hair mixing, hair combing, sliver making, combing, sliver mixing, primary stitching, secondary stitching, tertiary stitching, quaternary stitching, roving, spinning, spooling, doubling and two-for-one twisting. By the method, 100-count cashmere yarns or cashmere blended yarns can be produced, spinnability of the high-density cashmere yarns is improved, and the yarns are strong enough to respond to weaving tension.
Description
Technical field
The present invention relates to produce the method for cashmere fibres goods, more particularly, the present invention relates to a kind of method that high combing goat cashmere companion spins PVA Soluble Fiber goods of producing.
Background technology
Along with the consumer to the raising that comfort of fabric and taking require, produce spinning height and prop up the goat cashmere yarn and become a kind of trend, particularly use much in cloister fabric fields such as making tippet and scarf.Present spinning height props up the goat cashmere yarn and produces in batches generally below 80, and the batch process more than 100 is also relatively more difficult, and this mainly is because the characteristic limitations of cashmere fibres itself causes.In order to produce the spinning property that the goat cashmere yarn that is higher than 100 improves the goat cashmere high grade yarn, make yarn have enough brute forces simultaneously and deal with the tension force that produces when weaving.The time added fibrous raw materials such as PVA (solubility vinal) and silk in spinning, thereby the brute force of improving spinnability and the yarn of fiber is produced height and is propped up the goat cashmere yarn.
Summary of the invention
The objective of the invention is to characteristic according to goat cashmere; Necessary processing is carried out on the cashmere fibres surface; High combing goat cashmere companion spins PVA Soluble Fiber product requirements thereby change cashmere fibres surface characteristic adapts to production; And through the critical technical parameter in the control fabrication processes, thereby provide number to reach the above combing goat cashmere yarn goods of 100Nm (public).
To achieve these goals; The present invention provides the method that high combing goat cashmere companion spins PVA Soluble Fiber goods of producing; Said method comprises and the step of hair → carding → system bar → combing → silver mixing → scalp acupuncture → two pins → three pins → four pins → rove → spun yarn → winder → doubling → double twisting; And after in said and the hair step cashmere and other fibrous raw material being carried out shredding and adding and crude oil, water, antistatic additive, warp mixing, vexed storehouse make raw material have even degree of mixing and regain.
And the equipment that uses in the said step is homemade shredding, mixing willow, Italian import combing machine for fur, import gill box, import combing machine, rove, fine spining machine and import network, also, equipment such as sth. made by twisting.
Preferably, in described material choice, the average length of said goat cashmere is 35 to 40 millimeters, and containing short rate is 14% to 16%; The average fineness of said goat cashmere is 14 to 17 microns; The average length of said PVA bar is 70 to 80 millimeters, and fineness is 2.0 to 2.5dtex; The average length of spun silk is 55 to 65 millimeters, and fineness is 11 to 13 millimeters (being equivalent to diameter).
In said and hair step, the ratio of the weight of said goat cashmere and the weight of other fiber is carried out proportioning by requirement of products; Said PVA ribbon also carries out proportioning by technological requirement, and the PVA Soluble Fiber will not participate in wool blending step, mixes but in the silver mixing operation, add.
In said silver mixing step; The percentage that wool top that combing system bar is accomplished and said PVA bar account for gross weight is formulated the PVA bar by requirement of products and is carried out silver mixing (the PVA bar is not participate in wool blending step; Because PVA runs into water and will dissolve, the PVA bar there is no need to participate in combing simultaneously).
In said combing step, other fiber is all participated in combing process except PVA Soluble Fiber bar; And nip gauge is 27 to 29 millimeters, and to make the feeding Weight control be 150 to 200 gram/rice.
As used herein, said " nip gauge " is meant that bit is to the distance of choosing between the roller in the combing machine.
In said system bar step, drafting multiple is 3 to 4 times, and front ratch is 26 millimeters; In said silver mixing step, drafting multiple is 4 to 5 times, and front ratch is 28 millimeters.
As used herein, said " drafting multiple " is meant that the expression wool top receives the big or small value of tension in wool top elongation drawing-down process, and " drafting multiple " described herein is the mechanical commutation draft multiple, calculates according to those skilled in the art institute known method.
In said scalp acupuncture step, making the feeding Weight control is 80 to 100 gram/rice, and to make wool top weight be 12 to 17 gram/rice, and the shaping weight unevenness is controlled at below 1%.
As used herein, said " shaping weight unevenness " is meant the degree of irregularity through the wool top weight after the scalp acupuncture step, in %.
In said two pins, three stitchings were rapid, making wool top weight was 5 to 10 gram/rice; And in said four stitchings were rapid, making wool top weight was 2 to 4 gram/rice, and the shaping weight unevenness is controlled at below 1%.
In said rove step, drafting multiple is 8 to 12 times, and to make rove bar weight be 0.20 to 0.40 gram/rice; In said spun yarn step, drafting multiple is 18 to 22 times.
On the other hand; This paper also provides a kind of height according to the methods described herein preparation to prop up combing goat cashmere companion and spins PVA Soluble Fiber goods; The reality of said fibre is spun number and will be lower than the target number before the dissolving, and the number of the said fibre in dissolving back will reach the target number.
In one embodiment of the invention, the number of said fibre is 60 before the dissolving, and the number of the said fibre in dissolving back is 120.
And the single thread force of said fibre can both meet requirement of products before dissolving with after the dissolving.
Only if regulation is arranged among this paper in addition, the step that high combing goat cashmere companion of production described herein spins PVA Soluble Fiber article process is with reference to method well-known to those skilled in the art, for example winder, doubling step.
Only if regulation is arranged among this paper in addition, the assay method of all technological parameters of this paper all according to those skilled in the art understand, institute's common method carries out.
Beneficial effect of the present invention: compared with prior art, production of the present invention is higher than the spinning property of 100 goat cashmere yarn raising goat cashmere high grade yarn, makes yarn have enough brute forces simultaneously and deals with the tension force that produces when weaving.
