Embodiment 1

[0013] Example 1 Production 60 S Cotton pulp solvent method cellulose fiber pure spinning

[0014] Raw material: cotton pulp solvent method cellulose fiber: 1.33dtxe×38mm;

[0015] Routing

[0016] Cotton pulp solvent method cellulose fiber - plucking machine - mixed opener - lapping machine - carding machine - drawing frame (1) - drawing frame (2) - roving frame - spinning frame - winding machine.

[0017] Process parameters

[0018] Cotton pulp solvent method cellulose fiber raw materials are placed in loose bags for 24 hours in an environment with a relative humidity of 80%. Spend temperature: 22°C-25°C, relative humidity: 70%-80%; carding licker-in speed 700r / min, adopt 2520 series cylinder clothing, MCH36 cover card clothing, control neps within 2 grains / g ;Drawing speed is 280m / min, and the top rollers are pressurized in sequence: 23KN, 38KN, 6KN—pressure bar, 40KN, 32KN to ensure sufficient holding force; The stretching ratio is 1.8 times, and the drafting ratio...

Embodiment 2

[0022] Example 2 Production 32 S Cotton pulp solvent-process cellulose fiber 50% and JC cotton fiber 50% blended yarn

[0023] Raw material: cotton pulp solvent method cellulose fiber: 1.33dtxe×38mm;

[0024] JC cotton: grade 2.2, count 5800, main body length 29mm;

[0025] Routing

[0026] Raw material 1. Cotton pulp solvent method cellulose fiber - plucking machine - mixing opener - lapping machine - carding machine;

[0027] Raw material 2, JC cotton—cotton plucking machine—mixing opener—lapping machine—carding machine—pre-draw frame—strip coiling machine—combing machine; raw material 1 and raw material 2 are mixed according to the mass ratio: cotton pulp solvent Method cellulose fiber raw sliver 50% / JC cotton sliver 50% mixed head draw frame-second draw frame-three draw frame-roving frame-spinning frame-winder.

[0028] Process parameters

[0029] It is basically similar to Example 1: JC cotton is added with combing process: JC small roll quantitative 45g / m,...

Embodiment 3

[0033] Example 3 Production 40 S 40% cotton pulp solvent method cellulose fiber and 60% modal fiber blended yarn

[0034] Raw material: cotton pulp solvent method cellulose fiber: 1.33dtxe×38mm;

[0035] Modal fiber: 1.33dtxe×38mm;

[0036] Routing

[0037] Cotton pulp solvent method cellulose fiber / modal fiber - plucking machine - mixing opener - multi-compartment blending machine - lapping machine - carding machine - drawing frame (1) - drawing frame (2) - roving frame - spinning frame - winder.

[0038] Process parameters

[0039] It is the same as in Example 1: the key is the cleaning process, because the cotton box is used to mix cotton, so: (1) the arrangement of the cotton bale in the bale grabbing machine and the two fibers should be evenly spaced according to the 50 / 50 mass ratio, (2) in the process route A multi-chamber cotton blender is added after the blending opener, and the two fibers are more evenly mixed; the roving weight is 4.8g / 10m, the twis...

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 [0001] The patent of the present invention relates to spinning engineering in textile engineering, which refers to the pure spinning, blending and production process of cotton pulp solvent method cellulose fiber. Background technique [0002] The traditional process of producing cellulose fibers from cotton linter pulp requires chemical reaction of cellulose pulp to generate its derivatives, during which sulfuric acid, caustic soda, and other chemicals harmful to human body are used, and then the derivatives are regenerated For cellulose fibers, a large amount of sewage and waste gas will be discharged during the desulfurization and bleaching process after spinning, which seriously pollutes the ecological environment. The fiber produced by this production process is called viscose fiber. The breaking strength of viscose fiber is low. Generally, the dry breaking strength of viscose is about 2.2cN / dtex-2.3 cN / dtex, and the wet breaking strength is about 1.2cN / ...
