US Scientists Develop High Strength Spider Silk By Using Bacteria "Post Textile"

According to media reports, scientists in the United States have shown the research results of obtaining spider spider silk from bacteria and processing it. Through the standardization of the important process known as "post spinning", we have creatively reformed the purification process of spider silk, and laid the foundation for the production and application of high-strength synthetic spider silk.

Scientists say that during the post spinning process, spider silk molecules are stretched through mechanical actuators to enhance fiber strength. Research finds that Mechanics Stretching makes the synthetic spider silk very uniform, avoiding the errors in the process of artificial weaving. The result is that the spider silk produced by the synthetic spider silk is similar to the natural spider silk produced by the female black widow spiders, which is beyond the expectations of scientists.

In the laboratory, mechanical actuators can mimic spider's natural textile skills, and reliably synthesize spider silk fibers to a specific length. The researchers indicated that there were significant differences in mechanical properties between synthetic fibers before stretching and after stretching treatment.

It is reported that Synthesis Spider silk has many potential industrial applications. People are particularly interested in the strength of black widow spider silk. Analysis shows that its strength is comparable to Kevlar's fiber, and its weight is lighter and its density is lower. If people can produce large quantities of mechanical properties of spider silk, Synthetic silk Hopefully, it will replace Kevlar fiber, carbon fiber and steel. Synthetic spider silk will have a tremendous impact on the production of specific products, including bulletproof vest, aircraft fuselage and surgical suture.
