Embodiment 1

[0012] Sodium periodate oxidized cotton fabric (less oxidized) is treated as follows:

[0013] (1) Add cellulase and pectinase with a mass ratio of 2:1 in water, stir well to dissolve;

[0014] (2) Add cotton fabric to the above solution, control the bath ratio to 20:1, and the mass ratio of cotton fabric to cellulase and pectinase to 100:1:0.5, then raise the temperature of the solution to 50°C for 1 hour;

[0015] (3) Take the cotton fabric out of the solution, dehydrate and dry it.

Embodiment 2

[0028] Cotton fabric oxidized with sodium periodate (higher degree of oxidation) is treated as follows:

[0029] (1) Add cellulase and pectinase with a mass ratio of 2:1 in water, stir well to dissolve;

[0030] (2) Add cotton fabric to the above solution, control the bath ratio to 20:1, and the mass ratio of cotton fabric to cellulase and pectinase to 100:1:0.5, then raise the temperature of the solution to 50°C for 3 hours;

[0031] (3) Take the cotton fabric out of the solution, dehydrate and dry it.

Abstract

The invention relates to a method for improving the hydrophilicity of a sodium periodate oxidized cotton fabric, and belongs to the technical field of textile printing and dyeing. The method includesthe following processes that (1) cellulase and pectinase with a mass ratio of 2:1 are added into water, and fully stirring is carried out for dissolving; (2) a cotton fabric oxidized by sodium periodate is put into the solution, a bath ratio is controlled to be 20:1, the mass ratio of the cotton fabric to cellulase to pectinase is 100:1:0.5, and then the solution is heated to 50 DEG C for 1-3 hours; and (3) the cotton fabric is taken out from the solution, dehydrated and dried. The method utilizes the combination of cellulase and pectinase to modify the cotton fabric oxidized by periodate, andthe problem of the decrease in the hydrophilicity caused by oxidation can be effectively solved.

Description

technical field [0001] The invention relates to a method for improving the hydrophilicity of sodium periodate oxidized cotton fabric, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Cotton fiber is a kind of fiber whose basic component is cellulose, which has the characteristics of water absorption, warmth retention, heat resistance, alkali resistance and hygiene. Generally speaking, the cotton fabric after scouring and bleaching has good hydrophilicity, that is, it has a strong ability to absorb liquid phase water, and it can quickly form pores inside it when soaked in dyeing liquor, so that water-soluble dye molecules Into the inside of the fiber and successfully complete the dyeing process. [0003] In order to expand the application range of cotton and other cellulose materials, periodate is often used in the industry for selective oxidation treatment. The obtained products not only have good biocompatibility, degradabi...
