Problems solved by technology

However, wood fiber knitted fabrics are harder than cotton fiber knitted fabrics. If they are used as daily washing and daily necessities for human beings, the contact with the skin is hard and the touch is poor. As a result, the range of use of this high-quality natural fiber product is limited. limit
[0005] After searching, there are no patent reports and technical reports on the application of cellulase and pectinase in the finishing of wood fiber fabrics.

[0015] Example 1. Specification of wood fiber towel: 26×26cm 2

[0016] Put 10kg of the above fabric into an industrial washing machine, add 0.2kg of wetting agent JFC solution at 50°C, bath ratio 12:1, run for 15 minutes; then add 0.9kg of cellulase for treatment, temperature 45°C, use acetic acid-acetic acid Adjust the pH value to 5.5 with sodium for 12 minutes; then add 0.24 kg of pectinase for treatment at a temperature of 50°C and adjust the pH value to 5.5 for 35 minutes. Finally, wash with hot water at a temperature of 70°C for 20 minutes, with a bath ratio of 18:1, take out the vat, dehydrate, and dry.

[0017] Results: The breaking strength of the treated sample was 218.4N (compared to 231.6N), the drape coefficient was 35.29% (compared to 55.83%), the capillary effect was 14.6cm / 30min (compared to 9.6cm / 30min), the whiteness was 68% (compared to 44%), and the Coefficient 1.41% (control 2.37%).

Abstract

The invention relates to a finishing method of biological enzyme in wood fiber fabrics, which is characterized in that a nonionic wetting agent is adopted for preliminary treatment, cellulase and pectase are added for enzyme treatment, and finally, hot water is used for inactivation and washing. By adopting the method, the fabrics containing wood fibers have smooth and fluffy hand feelings, the service performance thereof is greatly improved, and the water absorption performance of the fabrics is further improved; since the cellulase and the pectase are used as finishing agents, chemical pollution can not be caused in production, hazardous substances can not remain in the fabrics, and the cellulase and the pectase can degrade after being discharged in an environment and can not pollute the environment, thereby the finishing method belongs to an environment friendly afterfinish technology. Through detection, after the treatment by the method, the water absorption performance of the wood fiber fabrics is improved by more than 34%, the strength damage is within 10%, the drapability, the white content and the pliability are obviously improved, and the improved magnitude is more than 30%.

Description

technical field [0001] The invention belongs to the technical field of finishing of fiber fabrics, and in particular relates to a method for improving the performance of wood fiber fabrics by using cellulase and pectinase. Background technique [0002] Wood fiber, also known as wood fiber (Wood Fiber), is one of the currently popular plant fibers in the world. It uses 2 to 3 years of fast-growing natural and non-polluting American deciduous trees (birches) as raw materials. After cooking with high temperature into wood pulp, it is made by extracting fibers. Wood fiber is an integral part of the xylem of trees. It has a strong supporting force. Its texture is fine and flexible. Because wood has inherent looseness and transportability, wood fiber products can be freely absorbed and evaporated. Moisture, with strong water absorption and oil discharge and decontamination ability. In particular, the water absorption and air permeability are superior to traditional cotton fabric...
