Abstract
The invention provides a fibroin reinforcing method for brittle silk fabric, which adopts the following steps: (A)adding silk fiber into CaCl<SUB>2</SUB> solution with weight percentage concentration of 50% at the ratio of 1:20-50 by weight, dissolving for 10-120 minutes at the temperature of 98+/-2 DEG C, cooling and filtering the dissolved solution, filling the filtrate into a dialysis bag and executing dialysis in deionized water, acquiring pure fibroin solution after 72 hours; (B) placing brittle silk fabric into the fibroin solution with weight percentage concentration of 0.1-5% at the ratio of 1:50-150 by weight, soaking for 1 minute to 2 hours, then naturally drying the silk fabric; (C) placing silk fabric into the glutaraldehyde solution with weight percentage concentration of 0.001-0.5% at the ratio of 1:50-150 by weight, soaking for 1 minute to 2 hours at the temperature of 25-35 DEG C; (D) acquiring fibroin reinforced silk fabric after naturally drying the processed product. The invention has advantages of simple method, easy operation, low cost, good effect, ability to greatly improve strength of silk cultural relics, benefit to cultural relics protection and so on.
Description
Technical field
What the present invention relates to is a kind of fibroin reinforcement process of fragile silk goods, belongs to the technical field of historical relic's protection.
Background technology
Silk is the symbol of Chinese mature culture.China all has a large amount of silk historical relics to be unearthed every year, these silk historical relics have been crossed over 6,000 years up and down, having very high history, archaeology and scientific value, is the important component part of China's historical relic, is research China successive dynasties politics, economy, art, the very important data in kind of scientific and technological aspects.Because silk protein is a kind of bioabsorbable polymer material, is easy to be subjected to multiple factor affecting and damaged.Different factors such as extraneous water, heat, oxygen, illumination, acid, alkali, microorganism all can cause the fracture of silk protein generation sex change and macromolecular chain, make silk fiber tender, fracture easily, and mechanical strength obviously descends.
Both at home and abroad the reinforcement protection to the silk historical relic mainly contains the braiding method for strengthening, mounts the holder method, coating method, silk net reinforcing method, resin method for strengthening, adhesive method for strengthening, group draw synthetic fibre vacuum coating method, grafting copolymerization process etc.; but all there is certain defective in these methods, and application is restricted.
The patent of invention of Hubei Provincial Museum (200410012737) discloses " the microorganism reinforcement means of no intensity silk ", and this invention is converted into cellulose with carbohydrate and organic acid with acetobacter, thereby reaches the purpose of reinforcing no intensity silk.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of method simple, easy to use, cost is low, effective, can increase considerably the intensity of silk historical relic, helps the fibroin reinforcement process of the fragile silk goods of historical relic's protection.
The objective of the invention is to finish by following technical solution, it adopts following steps:
A) silk fiber being put into weight percent concentration by weight 1: 20～50 is 50% CaCl
2In the solution,, with the lysate cooling, filter, and filtrate packed in the bag filter, place deionized water to dialyse, promptly obtain pure fibroin solution after 72 hours 98 ± 2 ℃ of down dissolvings 10～120 minutes;
B) fragile silk goods being placed weight percent concentration by weight 1: 50～150 is 0.1%～5% fibroin solution, flood taking-up after 1 minute to 2 hours, allows its air dry;
C) by weight 1: 50～150 silk goods being put into weight percent concentration again is 0.001～0.5% glutaraldehyde solution, and dipping is 1 minute to 2 hours under 25～35 ℃ condition;
D) after will product air dry, obtain silk goods through fibroin reinforcement through last processing.
Described silk fiber adopts fibroin fiber of handling through coming unstuck or the silk fiber that does not come unstuck and handle.
The present invention is under the help of auxiliary agent glutaraldehyde, utilizes fibroin to reinforce fragile silk goods, can improve the intensity of fragile silk goods significantly, is used for the protection of silk historical relic; The present invention compared with the prior art, have following outstanding advantage: 1) method is simple, and is easy to use; 2) cost is low, effective, can increase considerably the intensity of silk historical relic, helps the protection of historical relic; 3) do not influence outward appearance, color and the feel of silk historical relic; 4) utilize with the historical relic identical materials--fibroin is reinforced the silk historical relic, meet the principle of relevant " restoring the old as the old " in the historical relic's protection more, have durability simultaneously again.
