Method for preparing flax fiber in high cleavage degree

A technology of flax fiber and splitting degree, which is applied in the chemical post-treatment of fibers, fiber treatment, textiles and papermaking, etc. It can solve the problem of splitting degree, spinnability, cohesion not meeting the requirements, flax fiber is not soft enough, spinning To solve the problem of low count, achieve the effect of improving spinnability, good color fastness, and improving spinnability

Problems solved by technology

[0002] Commonly used flax treatment is generally alkali boiling, washing, dehydration, opening, drying, because the obtained flax fiber is not soft enough, the degree of splitting is low, the adaptability is poor, and the spinning count is not high. The flax disclosed in Chinese patent CN93100748.4 In the production method of cotton blended yarn, in the flax fiber treatment process, it is softened with a softener after washing, although the softness of the flax fiber has been improved, the cohesion of the fiber has been increased, and the spinnability of the fiber has been improved. It is only suitable as a raw material for low-count blended spinning. If you want to increase the spinning count up to 120 N Above, the degree of splitting, spinnability and cohesion are not up to the requirements

Embodiment Construction

[0020] The preparation method of high splitting degree flax fiber, the steps are:

[0021] 1. Enzymatic degumming of flax raw materials. The flax raw material is soaked in the aqueous solution added with the enzyme preparation, and the enzyme preparation is made up of pectinase and cellulase at a ratio of 1:1. The process conditions are controlled as follows:

[0022] Bath ratio 1:1.3-1.5

[0023] Temperature 38-40°C

[0024] pH 7-7.5

[0025] Time 6-7 hours

[0026] Feeding weight of enzyme preparation: 0.3%-0.5%

[0027] 2. Atmospheric oxygen bleaching. The process conditions are controlled as follows:

[0028] Temperature: 90-100℃ Time: 50-60 minutes

[0029] The aqueous solution contains: H 2 o 2 8-10g / L Na 2 CO 3 2-3g / L natronine 0.2-0.4g / L

[0030] 3. Acid-base neutralization and softening. The process conditions are controlled as follows:

[0031] Temperature: 50-60℃ Time: 20-30 minutes

[0032] The aqueous solution contains: silicone oil 15-25g / L acet...

Abstract

Preparation method of linen fiber of high fission belongs to the domain of weave. The stuff is come unglued by enzyme first, then oxygen bleach it in common pressure, acid and alkali neutralization, drying it and make linen fiber in wet condition. It improves the fission of the fiber and doesn't change its characteristic. The fission increases from 400 - 600 to more than 2000. The cohesion performance and spinnability of the fiber is improved. Blended yarn is high, can reach more than 160N.

Description

technical field [0001] The invention relates to the field of textiles, and refers to a method for preparing flax fibers with high splitting degree. technical background [0002] Commonly used flax treatment is generally alkali boiling, washing, dehydration, opening, drying, because the obtained flax fiber is not soft enough, the degree of splitting is low, the suitability is poor, and the spinning count is not high. The flax disclosed in Chinese patent CN93100748.4 In the production method of cotton blended yarn, in the flax fiber treatment process, it is softened with a softener after washing, although the softness of the flax fiber has been improved, the cohesion of the fiber has been increased, and the spinnability of the fiber has been improved. It is only suitable as a raw material for low-count blended spinning. If you want to increase the spinning count up to 120 N Above, the degree of splitting, spinnability and cohesion are not up to the requirements. Contents of...
