Problems solved by technology

High temperature can cause silk fiber degeneration, shrinkage, brittleness, yellowing, etc.; high humidity environment can not only cause slow hydrolysis of macromolecules and reduce the average molecular weight, reduce the strength of silk fiber, but also promote the growth and reproduction of mold and bacteria. And the enzymes secreted by bacteria can decompose protein macromolecules into small molecules and become their nourishment, which will lead to further mildew of silk fibers and seriously reduce the strength of fabrics

Abstract

The invention relates to a method for preparing a silk material used for the reinforcement and protection of rotten silk art treasure. The method comprises the following steps: firstly, non-degummed mulberry silk fiber with a denier of 13 / 15D is selected, and subjected to package rewinding under a certain condition; secondly, the mulberry silk fiber is twisted to between 2 and 22T / cm; thirdly, the mulberry silk fiber is subjected to shaping in a steaming box at a temperature of between 30 and 70 DEG C for 20 to 90 minutes; fourthly, the mulberry silk fiber is subjected to warping and quilling; fifthly, under the conditions of a reed number of between 6 and 30, a shed opening height of between 0.2 and 0.6cm and warp gaiting tension of 50 and 150cN, the mulberry silk fiber is woven according to plain weave, wherein the warp density of textile fabric is between 130 and 310 / 10cm, and the weft density of textile fabric is between 150 and 350 / 10cm; sixthly, the obtained textile fabric is soaked in fresh water at a temperature of 40 and 100 DEG C for 10 to 60 minutes and subjected to tentering drying to obtain a finished product. The method has the advantages that chemical auxiliary agents are not used; and, the silk material prepared has the advantages of good transparency, softness and smoothness and proper rigidity, and is quite suitable for the reinforced protection of rotten silk art treasures.

Description

technical field [0001] The invention relates to the technical field of silk weaving technology, in particular to a method for preparing a silk weaving material suitable for reinforcement and protection of decayed silk cultural relics. Background technique [0002] my country is the earliest country in the world to raise silkworms, reel silk and weave silk. A large number of silk cultural relics are unearthed every year. These cultural relics have witnessed the development of ancient Chinese civilization and have high historical, archaeological and scientific value. Silk cultural relics are an important part of our country's cultural relics, and they are extremely important physical materials for studying our country's politics, economy, culture, science and technology in the past dynasties. [0003] Silk is a natural protein fiber and a high molecular compound containing nitrogen, so it is vulnerable to light, heat, humidity and microorganisms. Light, especially ultraviolet...
