Natural spider silk is the toughest natural fiber known in nature, and its strength is comparable to high-performance fibers such as high-strength carbon fiber and aramid. The excellent strength and toughness characteristics make spider silk fibers have broad application prospects in fields such as national defense, military, and construction. However, because spiders cannot be farmed intensively and the production of natural spider silk is very small, it is difficult to obtain large quantities of spider silk for textiles.
Over the past few decades, researchers have been exploring the development of a fiber that is easy to produce and is as tough, lightweight and biodegradable as spider silk. Some people have also proposed to “transfer” the properties of spider silk. Ideas on silk. Silk silk is smooth and elastic, with high gloss and hygroscopicity. It is a commonly used high-end raw material in textiles. However, compared with spider silk, its strength and toughness are far insufficient.
Recently, the Tianjin University research team used a special chemical bath to remove the outer sericin and wax in ordinary silk, and combined with the method of metal ion-assisted enhancement, it obtained mechanical properties superior to The super strong silk fiber of spider silk.
