Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] Embodiments of the invention include:

[0015] A flax bleaching process, comprising the following steps:

[0016] In the first step, pretreatment, the flax product is soaked in the pretreatment mixed solution for 1h to 20h at a bath ratio of 1:8 to 1:10 and at a temperature of 20 to 50°C for 1h to 20h. Parts include 1-3ml / L of hydrogen peroxide (27.5%), 2-5ml / L of JNm-2 degumming enzyme with a pH value of 4.5-5.5, 1-4ml / L of JNm-6 catalase, 0.6-1.0ml 98% sulfuric acid per L, the balance being water;

Abstract

The invention discloses a linen bleaching processing technology. To-be-processed linen products are subjected to pretreatment, washing, chlorite bleaching, re-washing, oxygen bleaching and third washing. According to the manner, the invention provides the linen bleaching processing technology. Linen fibers are not damaged, the linen fibers are subjected to degumming and bleaching treatment with bio-enzymes so as to enhance yarn strength, the usage amount of the pollutant sodium chlorite is reduced by selecting an environment-friendly chloride-free solution, the air environment in a processingfactory is effectively improved, the processing operation difficulty is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a flax bleaching process. Background technique [0002] There are many flax factories in our country. Sodium chlorite bleaching and hydrogen peroxide bleaching are generally used in the degumming and bleaching of flax roving. [0003] Because sodium chlorite will emit toxic chlorine dioxide gas during bleaching, which is harmful to the health of workers, pollutes the environment, erodes equipment, and increases the difficulty of sewage treatment, which is neither economical nor environmentally friendly. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a flax bleaching process, which does not damage the flax fiber, adopts biological enzymes to degumming and bleaching the flax fiber to enhance the yarn strength, and at the same time selects an environmentally friendly chlorine-free solution to reduce the pollutant chlo...
