Abstract
The invention discloses a cotton pulp solvent method cellulose fiber pure/blended yarn and a production process thereof, relating to viscose, modal fibre, flexible fiber or chitosan fiber blended yarn produced from cotton pulp solvent method cellulose fibers by a viscose method; a blended yarn produced from the cotton pulp solvent method cellulose fibers and polyester fibers; a blended yarn produced from the cotton pulp solvent method cellulose fibers and wool or cashmere; a blended yarn produced from the cotton pulp solvent method cellulose fibers and spun silk; and a blended yarn produced from the cotton pulp solvent method cellulose fibers and various above-mentioned fibers. The process employs the conventional production process equipment for a cotton spinning mill; moreover, in the whole production process, the temperature and humidity of each process step are strictly controlled according to the technical requirements of the process step corresponding to the product so that the production is carried out smoothly. The production process of the invention is capable of spinning different styles of novel yarns by utilizing pure newest novel cotton pulp solvent method cellulose fibers or blending the novel cotton pulp solvent method cellulose fibers with various different fibers under the optimal predetermined technical conditions, thereby meeting the demands of different novel fabrics.
Description
Technical field
Patent of the present invention relates to the spinning engineering in the Textile Engineering, is meant that the cotton pulp cellulose fiber by solvent method purely spins, blending and production technology thereof.
Background technology
The technology that traditional cotton linter dissolving pulp is made cellulose fibre will make the cellulose pulp after chemical reaction generate its derivative earlier; To use therebetween sulfuric acid, caustic soda, etc. harmful chemicals; And then to make this derivates regeneration be cellulose fibre; Desulfurization bleaching process after spinning also will be discharged large amount of sewage and waste gas, serious pollution of ecological environment.Fiber with this production technology is produced is claimed viscose.The viscose fracture strength is low, and general viscose glue is done about fracture strength 2.2cN/dtex-2.3 cN/dtex, about wet breaking strength 1.2cN/dtex-1.3 cN/dtex.
Has no chemical reaction in the cotton pulp cellulose fiber by solvent method production technology; Only use nontoxic methyl horse beautiful jade oxide (NMMO) as solvent, with cellulose dissolution, make its concentrated spinning during low concentration during high concentration; Solvent is recyclable to be recycled, and production process is pollution-free.Powerful high (the doing about fracture strength 4.45 cN/dtex of cotton pulp cellulose fiber by solvent method; About wet breaking strength 4.35cN/dtex; Be the twice of viscose intensity), good hygroscopicity, smooth softness, have the silk gloss; Have the characteristic of cotton, polyester fiber and silk concurrently, spin or the thread lining of blended yarn can provide and develops high-grade clothing and Related product with the cotton pulp cellulose fiber by solvent method is pure.At present, still there is not this cotton pulp cellulose fiber by solvent method textile product both at home and abroad.
Summary of the invention
Main task of the present invention is: develop that a kind of cotton pulp cellulose fiber by solvent method purely spins, blended yarn and production technology thereof.For solve with cotton pulp cellulose fiber by solvent method raw material be processed into pure spinning and with the blended yarn of other fiber and the difficult problem of fabric thereof; The present invention adopts domestic cotton mill equipment commonly used; Spin test through a large amount of examinations; The spinning performance of exploratory development cotton pulp cellulose fiber by solvent method and with the technical data of various different fiber blends; Confirm best process flow and designing optimal technological parameter, reach effective control that fiber divides comb and drafting process, thereby obtain high-quality and stay-in-grade yarn; Simultaneously, carry out the blending ratio test according to the demands of different of Fabric Style again, confirm optimal blending ratio.
The present invention comprises product and two contents of method.
Products scheme: a kind of cotton pulp cellulose fiber by solvent method is pure to be spun, blended yarn, it is characterized in that spinning by the cotton pulp cellulose fiber by solvent method is pure, or and silk/cotton blended yarn; Viscose, Modal fibre, gentle silk fiber, chitin fiber blended yarn with adhesive means production; With the polyester fiber blended yarn; With wool, cashmere blended yarn; With the silk blending yarn; And with wherein two or more fiber blend yarn of above-mentioned multiple fiber.Realize that the cotton pulp cellulose fiber by solvent method purely spins, blended yarn; Used production technology adopts cotton mill production process equipment commonly used; Purely spin at the cotton pulp cellulose fiber by solvent method, in the blended yarn operation; One, blowing is placed cotton pulp cellulose fiber by solvent method bale breaking in the environment of relative humidity 80% 24 hours in advance, makes the abundant moisture equilibrium at dry side of fibrous inside; Blended yarn adopts multi-mixer, and is mixed more even; Adopt short flow process and select kirschner beater, with softly loosen, combing is main, lapper hired roughneck speed controlling in 800r/min, the blowing temperature: 18 ℃-32 ℃, relative humidity: 60%-80%; Two, comb carding step: licker-in speed adopts 2520 serial Bearded-needle knitted cloths less than 700r/min, and MCH36 flat-clothing, cotton knot are controlled in the 2/gram, to reduce fibre damage, rationally divide combing, effectively remove cotton knot, clear one-tenth net; Three, drafting speed of a motor vehicle 280-m/min, before and after the roller plus-pressure successively: 23KN, 38KN, 6KN-pressure bar, 40KN, 32KN; Head and total draft multiple are less than number of doubling, and back zone drafting multiple is greater than 1.7 times, two and the back zone be less than 1.2 times, hooked fibre is fully stretched, avoid increasing cotton knot; Four, the suitable grasp less than normal of rove operation drafting multiple, the drawing-off back zone is adopted and is a bit larger tham the drafting multiple of elasticity drawing-off, concentrates the proparea drawing-off, and the total draft multiple is controlled at 7-9 doubly; Five, spinning process is: the spun yarn twist factor improves 5%-10% than conventional products grasp bigger than normal.
Described cotton pulp cellulose fiber by solvent method is pure to be spun, blended yarn, is all formed by 100% cotton pulp cellulose fiber by solvent method spinning.
Described cotton pulp cellulose fiber by solvent method is pure to be spun, blended yarn; The blended yarn of producing by said cotton pulp cellulose fiber by solvent method and cotton, viscose, Modal fibre, the silk fiber that softens, chitin fiber, polyester fiber, wool, cashmere, spun silk; Its blending ratio is: cotton pulp cellulose fiber by solvent method 20%-80%; Cotton fiber, viscose, Modal fibre, gentle silk fiber, chitin fiber, polyester fiber, wool, cashmere, spun silk 80%-20%, number is 16
