Abstract
The present invention relates to a kind of protein-TG enzyme method for strengthening of fragile woollen fabrics, first fragile woollen fabrics be impregnated in keratin solution; Then be impregnated in glutamine transaminage solution, tiling after taking out, reacts 8 ~ 4h under temperature is 50 DEG C ~ 60 DEG C conditions; Finally wash 3 times, tiling, dries in the cool.The beneficial effect of the invention is: the present invention, under the help of glutamine transaminage (TG enzyme), adopts the polypeptide chain of keratin to fracture to reinforce, do not affect the outward appearance of wool fabric historical relic, have outstanding superiority in heat resistant.
Description
Technical field
The present invention relates to Techniques of Relics Protection field, is a kind of method for strengthening of fragile woollen fabrics, especially a kind of protein-TG enzyme method for strengthening of fragile woollen fabrics.
Background technology
Ancient times, wool fabric was the important component part in China's culture treasure-house, and the reinforcing for the fragile woolen knitwear be unearthed is the important topic that historical relic's protection worker explores always.Because woollen fabrics historical relic main component is protein, very easily in the process of burying, by degraded occurs in the effect of acid, alkali, salt etc., intensity is reduced, and because the equilibrium condition in the process of burying is destroyed after being unearthed, exacerbate the aging of woollen fabrics historical relic, make that the fiber brittle of woollen fabrics is weak, mechanical strength reduces.The unearthed woollen fabrics had is hardening, become fragile, and what have is broken, and being unable to undergo of having is hand-held, and one touches and namely breaks, and causes woollen fabrics historical relic to be difficult to preserve.In order to the requirement that satisfied collection is studied and displayed, need to carry out necessary reinforcing to increase its intensity to unearthed woolen knitwear.
The reinforcing of woollen fabrics should follow following basic principle: keep original appearance principle, ageing-resistant principle, intervene principle, invertibity principle less.At present, both at home and abroad the method for reinforcing and protecting of textiles historical relic is mainly contained: method for strengthening is mounted in holder, polyvinyl acetate membrane process, silk net reinforcing method, Pai Lalun membrane formation process, spraying dipping resin method, glass clamp are enforced the law.But all there is certain defect in these methods, application is restricted.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of protein-TG enzyme method for strengthening of simple to operation, effective fragile woollen fabrics, significantly to improve consolidation effect.
The present invention solves the technical scheme that its technical problem adopts: adopt following steps:
1) use the ratio of 2ml solution according to every square centimeter of fragile woollen fabrics, fragile woollen fabrics is placed in the keratin solution that mass percent is 0.1% ~ 5%, takes out flood 60min ~ 120min at 20 DEG C ~ 40 DEG C after;
2) ratio of 2ml solution is used according to every square centimeter of fragile woollen fabrics, by 1) the fragile woollen fabrics that obtains is placed in the glutamine transaminage solution that concentration is 2% ~ 20%, in temperature 45 C ~ 55 DEG C, flood 120min ~ 60min under the condition of pH value 5.0 ~ 7.0 to take out, tiling, reacts 8 ~ 4h under temperature is 50 DEG C ~ 60 DEG C conditions;
3) the fragile woollen fabrics through above-mentioned process is washed 3 times, tiling, dries in the cool, obtains the fragile woollen fabrics through keratin-TG enzyme consolidation process.
As preferably, the enzyme of glutamine transaminage is lived as 100u/g.
Inventing useful effect is: the present invention, under the help of glutamine transaminage (TG enzyme), adopts the polypeptide chain of keratin to fracture to reinforce, do not affect the outward appearance of wool fabric historical relic, have outstanding superiority in heat resistant.
Detailed description of the invention
The invention will be further described below:
