[0014] Example 3 Enzymatic cooking with addition of glucose oxidase preparation and substrate glucose in the cooking bath

[0015] Fabric: Pure cotton poplin (15tex×15tex 524 / 10cm×283 / 10cm)

[0016] Enzymatic cooking process: enzymatic desizing, enzymatic cooking: alkaline pectinase 1.5g / L, glucose oxidase preparation (compounded by glucose oxidase and glucose amylase, its mass ratio is 1:0.2 ) 0.3g / L, glucose 3g / L, osmotic agent JFC 8g / L, pH7.0~8.0, temperature 75°C, 70min, bath ratio 1:20, bleaching.

[0017] enzymatic cooking process

[0018] Glucose oxidase preparations are added during cooking to generate hydrogen peroxide with glucose as a substrate. The amount of hydrogen peroxide produced is 500-1500 mg / L. It can be seen from the experimental results that the glucose oxidase preparation can indeed promote the scouring effect of biological enzymes on cotton fabrics. After the treatment, the wettability, whiteness, removal rate of impurities such as pectin...

Abstract

The invention discloses a boiling method of glucose oxidase agent, which is characterized by the following: adding glucose oxidase agent in the cotton fabric enzymatic boiling course; adopting glucose as substrate to produce hydrogen peroxide at 60-80 deg.c at 6.0-8.0 pH value; removing non-fiber impurity; improving wetness and whiteness for enzymatic fabric.

Description

technical field [0001] The invention discloses a cotton fabric enzymatic scouring method using glucose oxidase preparation, which is a new method suitable for cotton fabric biological enzymatic scouring, and can improve the performance of the fabric after biological enzyme treatment. It relates to the technical field of compounding technology of glucose oxidase preparation and its application in cotton fabric pretreatment process. Background technique [0002] Cotton fabrics are scoured with biological enzymes. Due to the mildness of enzyme action conditions and the specificity of enzymes, the accessibility and destructiveness of enzymes to impurities on cellulose fibers are not as good as those treated with high temperature and strong alkali. Therefore, when scouring cotton fabrics with enzymes, if the surface of cotton fibers is damaged to a certain extent, the accessibility of enzymes and the removal rate of impurities can be improved. Hydrogen peroxide is a strong oxidi...
