Description

A kind of keratin EGDE strengthens the weak wool fabric method

technical field

The invention relates to a method for strengthening fragile wool fabrics, in particular to a method for strengthening fragile wool fabrics with keratin EGDE.

Background technique

Wool fabric, as a kind of natural fiber, was widely used in clothing and blankets in the ancient northern region, of which wool fabric accounted for the majority. About 3,800 years ago, a large number of precious woolen garments were unearthed in the Xiaohe cemetery in Xinjiang, which is as exquisite as the unearthed silk fabrics. They are not only important physical evidence of the evolution of ancient textile and weaving technology, but also important for understanding the location of the tomb owner at that time. Its social environment and human activities have important reference value.

Research shows that at this stage, there are few researches on wool fabric reinforcement at home and abroad. Referring to other fabric reinforcement methods, it can be divided into physical reinforcement, chemical reinforcement, and biological reinforcement. For wool fabrics that are in a good preservation condition and have a certain strength, there are physical reinforcement methods such as transparent thin plate interlining method, traditional mounting method, weaving reinforcement, and wire mesh reinforcement technology. The chemical method is mainly to increase the strength of cultural relics by adding polymer compounds on the cultural relics to form a film on the surface of cultural relics or adding additives to form chemical bonds at the breakage of fabric fibers. These polymer materials have the advantages of aging resistance, colorless transparency, flexibility, reversibility, and moderate viscosity. However, chemical reinforcement in the past often caused problems such as fabric stiffness and easy aging damage. Bioreinforcement is based on biotechnology, using microorganisms to synthesize bacterial cellulose on textiles to form a cellulose network or cellulose film, thereby playing a reinforcing role. However, bacterial cellulose is quite different from protein materials.

Contents of the invention

The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a method that is simple and convenient to operate, has low requirements on the environment, has little impact on fabrics, and has a good reinforcing effect on fragile woolen fabrics.

The technical scheme that the present invention solves its technical problem adopts: comprise the following steps:

1) Put the wool fiber into the NaOH solution with a concentration of 8% by weight at a weight ratio of 1:20~50, dissolve it at 65±2°C for 60~120 minutes, cool the solution, filter it, and pack the filtrate Put it into a dialysis bag, put it in deionized water for dialysis, change the water every 12 hours until it is neutral, and dry it in a cool air to get a pure keratin solution;

² ) Put the fragile woolen fabric in the proportion of 5-10mL of 1cm2 fabric in the keratin solution with a concentration of 0.5% by weight, and take it out after soaking for 10-20 minutes;

3) Put 5-10mL of the treated fragile wool fabric in ² ) into the amino acid solution with a concentration of 1% by weight at a ratio of 5-10mL per 1cm2 of fabric, and then take it out after immersing for 5-20 minutes;

4) Put the fragile wool fabric after 3) into the ethylene glycol diglycidyl ether solution with a concentration of 0.5 to 4.5% by weight in the proportion of 5 to 10 mL of 1 cm ² fabric, and the ethylene glycol diglycidyl ether solution Adjust the pH value to 6.5, and soak for 5 minutes to 2 hours under the condition of 25-35°C;

5) Lay the fragile wool fabric after the above treatment on a flat surface, and cure it at 80-85°C for 5-6 hours;

6) Wash the fabric obtained in step 5) three times with deionized water, spread it flat again, and dry it in the shade.

As a preference, the amino acid solution in 3) is prepared in proportion by mass parts of 1.5 parts of cysteic acid and 1 part of aspartic acid.

The wool fiber in it is untreated wool fiber.

The beneficial effect of the invention is that the wool homologous material keratin is used as the reinforcement material, which is convenient, fast, efficient and harmless, and has low requirements on the environment. The breaking strength of the fragile wool fabric reinforced by the invention is obviously improved.
