Abstract

The present invention relates to a method for strengthening a fragile wool fabric through keratin EGDE. The method comprises: immersing a fragile wool fabric in a keratin solution for a certain time according to a certain ratio, immersing the fragile wool fabric in an amino acid solution for a certain time according to a certain ratio, immersing the fragile wool fabric in an ethylene glycol diglycidyl ether solution according to a certain ratio, taking, curing, washing with deionized water, re-paving, and carrying out air drying in a shady place. According to the method, the wool homologous substance keratin is adopted as the strengthening material, such that characteristics of convenience, fastness, efficiency, no harm and low environment requirements are provided; and breaking force of the fragile wool fabric strengthened by using the method is significantly improved.

Description

A kind of keratin EGDE reinforces the method for fragile wool fabric
Technical field
The present invention relates to a kind of method of reinforcing fragile wool fabric, especially a kind of keratin EGDE reinforces the method for fragile wool fabric.
Background technology
Wool fabric is as a kind of natural fabric, and northern area is widely used in dress ornament and woollen blanket etc. in ancient times, wherein with wool fabric, is in the great majority.Xinjiang Xiaohe cemetery apart from modern about 3800, the woolens dress ornament of a large amount of preciousnesses of being unearthed, its exquisite degree is not second to unearthed silk fabric, they are not only the important tangible evidence that the weaving technology of weaving ancient times develops, and also to understanding social environment and the humanity activities situation at tomb owner people place at that time, have important reference value.
Research shows, present stage, the research of both at home and abroad wool fabric being reinforced is less, with reference to the reinforcement means of other fabric, can be divided into physics and reinforce, chemical consolidation, bioreinforcement etc.For preservation situation better and there is the wool fabric of some strength, there are thin transparent plate holder lining method, tradition to mount the physics reinforcement means such as holder method, braiding reinforcing, silk net reinforcing technology.Chemical method is mainly to form film or add auxiliary agent in fabric fibre breaking part formation chemical bond increase historical relic intensity at cultural artifact surface by add macromolecular compound on historical relic.That these macromolecular materials have is ageing-resistant, water white transparency, pliability, invertibity, modest viscosity advantage, but chemical consolidation in the past often brings the problems such as fabric hardens, easy aging damage.Bioreinforcement is to take biotechnology as basis, utilizes microorganism synthetic bacteria cellulose on textiles, forms cellulose net or cellulose membrane, thereby plays the effect of reinforcing.But there is larger difference in bacteria cellulose and protein material.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provide a kind of simple to operation, on environment require low, little on fabric impact, to the good method of fragile wool fabric consolidation effect.
The present invention solves the technical scheme that its technical problem adopts: comprise the following steps:
1) wool fibre being put into weight percent concentration by weight 1:20～50 is in 8% NaOH solution, at 65 ± 2 ℃, dissolve 60～120 minutes, lysate is cooling, filtration, and filtrate is packed in bag filter, being placed in deionized water dialyses, every 12h changes water until neutrality, the shady and cool air-dry pure keratin solution that obtains;
2) fragile wool fabric is pressed to 1cm 2it is 0.5% keratin solution that the ratio of fabric 5～10mL is placed in weight percent concentration, floods after 10～20 minutes and takes out;
3) again by 2) fragile wool fabric after processing presses 1cm 2it is that 1% Freamine Ⅲ floods after 5～20 minutes and takes out that the ratio of fabric 5～10mL is placed in weight percent concentration;
4) again by 3) fragile wool fabric after processing presses 1cm 2it is 0.5～4.5% ethylene glycol diglycidylether solution that fabric 5～10mL ratio is put into weight percent concentration, and the pH value of ethylene glycol diglycidylether solution is adjusted to 6.5, floods 5 minutes to 2 hours under the condition of 25～35 ℃;
5) the fragile woollen fabrics after above processing is being tiled, at 80～85 ℃, solidifying 5～6 hours;
6) deionized water washing 3 times for fabric step 5) being obtained, tiling, dries in the cool again.
As preferably, described 3) Freamine Ⅲ in, by 1.5 parts of cysteines of mass fraction, 1 part of aspartic acid, is made in proportion.
Wool fibre wherein adopts untreated wool fibre.
The effect that the present invention is useful is: adopt wool homology material keratin as reinforcement material, have convenient, fast, efficient, harmless, and low to environmental requirement.The ultimate strength of the fragile wool fabric after the present invention reinforces is significantly improved.
