Problems solved by technology

[0003] In order to meet the above CIE whiteness requirements, the existing process is to carry out oxygen bleaching, dyeing, and soaping on the sub-bleached pure linen yarn until soft. The result of this treatment is that the yarn strength is obviously damaged and there are many defects. , leading to serious yarn breakage in each process of rewinding, warping and weaving, affecting production efficiency and product quality

Embodiment Construction

[0015] One, 21 S The inherent qualities of pure linen bobbins:

[0016] The average yarn strength is ≥700CN, the minimum strength is ≥500CN, and the strength CV value is ≤20.

[0017] 2. Enzyme refining:

[0018] 1. Refining mixture formula:

[0019] Water is mixed with pectinase, scouring agent and chelating agent to form a scouring mixture, wherein the content of pectinase is 3g / L, the content of scouring agent is 1g / L, and the content of chelating agent is 1g / L.

[0020] 2. Refining process parameters:

[0021] The heating rate is 3°C / min, the temperature is kept at 60°C for 60 minutes, the liquor ratio is 7-9, and the dyeing pump speed is 100%.

[0022] 3. Oxygen bleaching:

[0023] 1. Oxygen bleach formula:

[0024] Mix water with hydrogen peroxide (27.5%), multifunctional compound enzyme, scouring agent, yarn protectant and chelating agent to form an oxygen bleaching solution, wherein the content of hydrogen peroxide (27.5%) is 2g / L, and the content of multifunctio...

Abstract

The invention relates to a production process of pure linen cheese. Pure linen cheese which has undergone chlorite bleaching is then subjected to oxygen bleaching, dyeing, softening and yarn drying processes. The invention is characterized in that pure linen cheese is subjected to bio-enzyme scouring treatment before oxygen bleaching, and a mixed solution for the bio-enzyme scouring is mainly composed of pectinase, scouring agent and chelating agent; the heating rate of a rinsing liquid used in the oxygen bleaching is 1-1.5 DEG C / min; during the softening process, a hydrophilic softener is adopted; and the moisture content of the cheese obtained after the yarn drying is 6-8%. By the process, hydrophilicity of the fiber can be enhanced and hand feeling of the yarn can be improved, strengthreduction rate of the yarn is reduced, rewinding is promoted for the linen yarn, capillary effect of the yarn is improved, and the soft hand feeling is beneficial to subsequent weaving.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to the production process of flax cheese. Background technique [0002] The pure linen yarn purchased at present is the thread that has been sub-bleached. The CIE whiteness value of the linen yarn after sub-bleaching is less than 60. At least reach 70 or more. [0003] In order to meet the above CIE whiteness requirements, the existing process is to carry out oxygen bleaching, dyeing, and soaping on the sub-bleached pure linen yarn until soft. The result of this treatment is that the yarn strength is obviously damaged and there are many defects. , leading to serious yarn breakage in each process of rewinding, warping and weaving, which affects production efficiency and product quality. Contents of the invention [0004] The purpose of the invention is to propose a production process for pure flax cheese that has little damage to fibers and can meet the requirements of...
