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 the method for producing cashmere fibres goods, more particularly, the present invention relates to an a kind of height combing cashmere of producing and accompany the method spinning PVA Soluble Fiber goods.
Background technology
Along with the raising that consumer requires comfort of fabric and taking, producing worsted high-count cashmere yarn has become a kind of trend, particularly a lot of in field application such as zephyr such as making tippet and scarf etc.The batch production of current worsted high-count cashmere yarn is general that below 80, the batch production of more than 100 is also more difficult, and this is mainly because the characteristic of cashmere fibres itself limits and causes.In order to produce the spinning property improving cashmere high grade cotton yarn higher than the cashmere yarn of 100, make yarn have enough brute forces to deal with the tension force produced when weaving simultaneously.PVA(soluble polyvinyl alcohol fiber is added when spinning) and the fibrous raw material such as silk, thus the brute force of the spinnability and yarn of improving fiber is produced and is highly propped up cashmere yarn.
Summary of the invention
The object of the invention is to the characteristic according to cashmere, necessary process is carried out to cashmere fibres surface, thus change cashmere fibres surface characteristic adapts to produce the requirement that high combing cashmere companion spins PVA Soluble Fiber goods, and by controlling the critical technical parameter in fabrication processes, thus provide number to reach 100Nm(public affairs) more than combing cashmere yarn goods.
To achieve these goals, the invention provides and produce the method that high combing cashmere companion spins PVA Soluble Fiber goods, described method comprises the step with hair → carding → bar → combing → silver mixing processed → scalp acupuncture → bis-pin → tri-pin → tetra-pin → rove → spun yarn → winder → doubling → double twisting, and carry out shredding to cashmere and other fibrous raw material in described and hair step and after adding wool lubricant, water, antistatic additive, through mixing, vexed storehouse makes raw material have homogeneous blend and regain.
And the equipment used in described step is domestic shredding, mixing willow, Italian import combing machine for fur, import gill box, import combing machine, rove, spinning frame and import network and, the equipment such as sth. made by twisting.
Preferably, in described raw material is selected, the average length of described cashmere is 35 to 40 millimeters, is 14% to 16% containing short rate; The average fineness of described cashmere is 14 to 17 microns; The average length of described 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 described and hair step, the ratio of the weight of described cashmere and the weight of other fiber is to carry out proportioning by the requirement of product; Described PVA ribbon also carries out proportioning by technological requirement, and PVA Soluble Fiber will not participate in wool blending step, but adds in silver mixing operation and mix.
In described silver mixing step, the percentage that the wool top complete combing bar and described PVA bar account for gross weight carries out silver mixing by the requirement of product to formulate PVA bar (PVA bar does not participate in wool blending step, because PVA runs into water and will dissolve, PVA bar there is no need to participate in combing simultaneously).
In described combing step, except PVA Soluble Fiber bar, other fiber all participates in combing process; And nip gauge is 27 to 29 millimeters, and feeding Weight control is made to be 150 to 200 grams/meters.
As used herein, described " nip gauge " refers to that in combing machine, bit is to the distance of choosing between roller.
In described bar step processed, drafting multiple is 3 to 4 times, and front ratch is 26 millimeters; In described silver mixing step, drafting multiple is 4 to 5 times, and front ratch is 28 millimeters.
As used herein, described " drafting multiple " refers to the value representing wool top tension power effect size in wool top elongation drawing-down process, and " drafting multiple " described herein is mechanical commutation draft multiple, calculates according to the known method of those skilled in the art.
In described scalp acupuncture step, make feeding Weight control be 80 to 100 grams/meters, and make wool top weight be 12 to 17 grams/meters, and shaping weight unevenness is controlled below 1%.
As used herein, described " shaping weight unevenness " refers to the degree of irregularity of the wool top weight after scalp acupuncture step, in %.
In described two pins, three stitchings are rapid, wool top weight is made to be 5 to 10 grams/meters; And in described four stitchings are rapid, make wool top weight be 2 to 4 grams/meters, and shaping weight unevenness is controlled below 1%.
In described rove step, drafting multiple is 8 to 12 times, and makes rove bar weight be 0.20 to 0.40 gram/meter; In described spun yarn step, drafting multiple is 18 to 22 times.
On the other hand, also provide a kind of height prepared according to methods described herein to prop up combing cashmere companion herein and spin PVA Soluble Fiber goods, the reality of the front described fibre of dissolving spins number will lower than target number, and after dissolving, the number of described fibre will reach target number.
In one embodiment of the invention, before dissolving, the number of described fibre is 60, and after dissolving, the number of described fibre is 120.
Further, the single thread force of described fibre can meet the requirement of product before dissolving and after dissolving.
Unless separately had regulation herein, a production height described herein combing cashmere companion spins the step of PVA Soluble Fiber article process with reference to method well-known to those skilled in the art, such as winder, doubling step.
Unless separately had regulation herein, the assay method of all technological parameters is all understood according to those skilled in the art herein, institute's common method carries out.
Beneficial effect of the present invention: compared with prior art, the present invention's production, higher than the spinning property of the cashmere yarn raising cashmere high grade cotton yarn of 100, makes yarn have enough brute forces to deal with the tension force produced when weaving simultaneously.
