Problems solved by technology

[0002] At present, the bamboo fiber generally used is the process of making cellulose fiber with traditional viscose. First, the bamboo cellulose pulp will be chemically reacted to generate its derivatives, during which sulfuric acid, caustic soda, and other chemicals harmful to the human body will be used. Then the derivatives are regenerated into cellulose fibers, and a large amount of sewage and waste gas are discharged during the desulfurization and bleaching process after spinning, which seriously pollutes the ecological environment.

Embodiment 1

[0007] Production 60 S Bamboo pulp solvent method cellulose fiber pure spinning

[0008] Raw material: 1. Bamboo pulp solvent-process cellulose fiber: 1.33dtxe×38mm;

[0009] 2. JC cotton: grade 2.1, count 5900, main body length 29mm;

[0010] Routing

[0011] Raw materials 1. Bamboo pulp solvent-process cellulose fiber—cotton plucking machine—mixing opener—lapping machine—carding machine;

[0012] Raw material 2. JC cotton—cotton plucking machine—mixing opener—lapping machine—carding machine—pre-drawing frame—strip coiling machine—combing machine;

[0013] Raw material 1 and raw material 2 are mixed according to the mass ratio: bamboo pulp solvent method cellulose fiber raw sliver 50% / JC cotton sliver 50% mixing head draw frame - second draw frame - third draw frame - roving frame - spinning frame - automatic winder.

[0014] Process parameters

[0015] Bamboo pulp solvent method cellulose fiber raw materials are placed in loose bags for 24 hours in an environment wit...

Embodiment 2

[0019] Production 40 S Blended yarn of 50% bamboo pulp solvent-process cellulose fiber and 50% soft silk fiber

[0020] Raw material: bamboo pulp solvent-process cellulose fiber: 1.33dtxe×38mm;

[0021] Soft silk fiber: 1.33dtxe×38mm;

[0022] Routing

[0023] Bamboo pulp solvent method cellulose fiber / soft silk fiber - plucking machine - mixing opener - multi-compartment blending machine - lapping machine - carding machine - drawing frame (1) - drawing frame (2) - Roving frame - spinning frame - winding machine.

[0024] Process parameters

[0025] This embodiment differs from Example 1 mainly by changing the drawing frame blending to two kinds of raw materials and adopting the cotton box blending cotton, because the cotton box blending is adopted, (1) the arrangement of the cotton bales in the bale grabbing machine and the two fibers should be according to 50 / The mass ratio of 50 is arranged evenly at intervals, (2) In the process route, a multi-compartment cotton bl...

Embodiment 3

[0029] Production 60 S Blended yarn of 65% bamboo pulp solvent-process cellulose fiber and 35% spun silk

[0030] Raw material: bamboo pulp solvent-process cellulose fiber: 1.33dtxe×38mm;

[0031] Silk fiber 1.33dtxe×38mm;

[0032] No. 1 silk strip

[0033] Routing

[0034] Bamboo pulp solvent method cellulose fiber: plucking machine-mixing opener-lapping machine-carding machine;

[0035] Mixing of two kinds of fibers: 65% of bamboo pulp solvent method cellulose fiber and 35% of silk slivers are mixed at the head draw frame-second draw frame-three draw frame-roving frame-spinning frame-winding machine.

[0036] Process parameters

[0037] It is basically similar to Example 1, except that the spun silk does not need a combing process, and two kinds of fibers are directly mixed in the drawing process: the bamboo pulp solvent method cellulose fiber and the silk sliver adopt a three-way mixing process, and three-way drying The quantitative roving weight is 3.9g / 10m, the twi...

Abstract

The invention discloses a bamboo pulp solvent-method cellulose fiber blended yarn and a production process thereof. The invention comprises a product and a method as follows: the bamboo pulp solvent-method cellulose fiber blended yarn is formed by blending bamboo pulp solvent-method cellulose and cotton, blending a viscose type cellulose fiber produced by a viscose method, a modal fiber and a flexible wire fiber, blending with spun yarn, and blending two or more than two fibers in a plurality of the fibers. The bamboo pulp solvent-method cellulose fiber blended yarn is produced in a certain requirement condition through a process flow. The bamboo pulp solvent-method cellulose fiber blended yarn and the production process thereof provided by the invention have beneficial effects as follows: the most novel bamboo pulp solvent-method cellulose fiber is blended with the cotton, the viscose type cellulose fiber, the modal fiber, the flexible wire fiber, and the spun yarn; different types of novel yarns with high quality can be spun in conditions of selecting an optimal process flow and setting optimal process parameters, so as to meet different requirements of the novel woven fabric.

Description

technical field [0001] The patent of the present invention relates to spinning engineering in textile engineering, referring to bamboo pulp solvent-process cellulose fiber blending and its production process. Background technique [0002] At present, the bamboo fiber commonly used is the process of making cellulose fiber with traditional viscose. First, the bamboo cellulose pulp will be chemically reacted to generate its derivatives, during which sulfuric acid, caustic soda, and other chemicals harmful to the human body will be used. Then the derivative is regenerated into cellulose fiber, and a large amount of sewage and waste gas will be discharged during the desulfurization and bleaching process after spinning, seriously polluting the ecological environment. The bamboo fiber produced by this production process is called viscose bamboo fiber. The breaking strength of viscose bamboo fiber is low, the dry breaking strength of high-quality viscose bamboo fiber is about 2.2cN...
