Technology: Magic Silk Can Turn Into Razor.

In the early days of China, silk was used to make clothes or silk. But do you know that with the progress of science and technology, silk has been able to replace "titanium" to make razor blades? Razors are often placed in places with high humidity. In terms of material selection, it is necessary to make "steel alloys" or "titanium" with high rust resistance to avoid rust. In order to make the razor blade without deformation and flexible use, the hardness of the steel sheet must be high enough and flexible. University of Oxford professor Fritz allas (Fritz Vollrath) studied silkworms, spiders and insects, and found that they could precisely control moisture and abdominal pressure to fold silk. So silk itself had super toughness and elasticity. Using these characteristics, silk was made of geometric structure equivalent to "titanium" metal and made of razor blade.

A razor made from silk can remove hundreds of fine hairs on the surface of the skin without scratching the skin. Just like a small lawn mower with a hand push, such a blade has helped to solve the environmental and employment crisis. At the same time, the price is only 1/6 of expensive metals such as stainless steel or titanium.

Silk substitution Food preservation

Mulberry and silk are widely used. Mulberry has the function of growing and protecting soil and water in dry land. The excretion of mulberry leaves after being eaten by mulberry leaves can quickly produce nutrients and make the soil more fertile. Bacteria have been planted in large numbers of Chinese people centuries ago to solve the problem of increasing population and food demand but limited fertile soil. Moreover, this method has been in operation for many years and extended to the Middle East and European countries.

In the past, the "silk" handicrafts made in China were made of silk. At that time, the amazing industry was created. The concept of silk spinning was invented by Huang Di, Queen of Xiling. (Lei Zu): one afternoon, when Lei Zu was sitting under a mulberry tree, a cocoon fell into her teacup. She saw the smooth cocoon gradually unraveling, and lifted the cocoon from the cup, but was surprised to pull out thousands of yarns. After that, the queen of Xiling developed silk to make clothes, and used it to wrap vegetables and fruits. Later generations proved that this is indeed a feasible preservation technology.

In recent years, silk application Great progress has also been made in medicine. Silk thread is widely used as a suture line for precision surgery and ophthalmic surgery. Its soft fiber and strong tensile toughness are suitable for surgical suture, and silk protein is compatible with human body and does not need surgical removal.

Other silk medical products have also been commercialized. For example, anti haze respirators, gauze mats, bandages for skin diseases are all made of silk thread. In addition, the technology of "decomposition of silk fiber" and "silk protein manufacturing film" has also opened up the research and development of silk in artificial skin, blood vessels, tendons, nerve regeneration, contact lenses, surgical catheters and anticoagulants, all of which have made good use of silk's biocompatibility and permeability.

Amazing achievements in 10 years

The perpetual mode of the silk industry is both renewable and reducing carbon emissions. Over the past 10 years, 100 thousand tons of silk have transformed 6 million 250 thousand acres of dry land into fertile land. At the same time, because of the reduction of ore mining, avoiding mining, ore processing and fertilizer produced by Nitrous Oxide, can reduce 10 million tons of carbon dioxide emissions!

With the expansion of the silk industry, in the past 10 years, 2.4 jobs have been created on average, creating 15 million jobs in total, which is far more than the number of jobs that the energy and mining industries may disappear.
