Spider silk is expected to be used to make high-strength materials, and experts from the Institute of Gene Biology of the Russian Academy of Sciences are actively studying the use of spider silk to make high-strength materials. There is a rotator behind the spider's abdomen, which is filled with rotator glands. Protein mucus secreted by this gland can condense into extremely strong Jilin silk in the air. According to the Moscow Communist Youth League newspaper, experts from the Institute of Gene Biology of the Russian Academy of Sciences found that the hardness of this material is nine times higher than that of steel with the same thickness, and the elasticity is twice as high as that of other most elastic synthetic materials. Experts believe that after further processing, the silk raw materials in Jilin Province can be used to manufacture light body armor, protective materials for weapons and equipment, wheel tires, plastic surgery appliances, high-strength fishing nets and so on.
