Embodiment 1

[0026] Coconut water was used as the culture medium to inoculate activated Gluconoacetobacter xylinum, the inoculum amount was 8% of the weight of the culture medium, and the shallow plate was statically fermented at 28°C for 7 days, and a biocellulose film was obtained on the surface of the culture medium with a thickness of 15mm. After cutting it into a mask product of proper shape, the remaining small pieces of corner gel product are ready for use.

Embodiment 2

[0028] With glucose 3wt%, sucrose 2wt%, yeast extract 1wt%, peptone 0.5wt%, disodium hydrogen phosphate 0.2wt%, dipotassium hydrogen phosphate 0.1wt%, magnesium sulfate 0.1wt%, agar 2wt% and 91.1wt% water It is prepared as a culture medium, inoculated with activated Acetobacter xylinum, the inoculation amount is 10% of the weight of the medium, and fermented dynamically in shake flasks or other containers at 26°C for 5 days, and a spherical biocellulose gel is obtained in the medium particles.

[0029] 2. After the biological cellulose is dried, it is dissolved in a solvent system, and the fiber pulp is obtained after high-speed stirring.

Embodiment 3

[0031] The small corner gel product obtained in Example 1 is dried by hot air until the water content is less than or equal to 10%, and then dissolved in a solvent system, the solvent system is 6% aqueous sodium hydroxide solution and dimethylformamide by volume Mixing system with a ratio of 1:1, continuous stirring, to obtain biocellulose fiber pulp.

Abstract

The invention relates to an elastic fiber fabric for a body armor. The elastic fiber fabric is prepared by blending biological cellulose fibers, spandex fibers and metal fibers. The weight ratio of the biological cellulose fibers to the spandex fibers to the metal fibers is (5: 3: 2)-(7: 2: 1). The biological cellulose fibers are prepared by drying biological cellulose, dissolving the dried biological cellulose in a solvent system, and stirring at a high speed to obtain fiber pulp. The metal fibers comprise stainless steel fibers, aluminum fibers and nickel fibers. The elastic fiber fabric disclosed by the invention has the characteristics of light weight, soft and breathable texture, high elasticity and the like, can effectively absorb kinetic energy and heat energy of bullets or shrapnel, and has an obvious protection effect on low-speed bullets or shrapnel such as pistols and the like; various forms of elastic fiber fabrics can be woven; and the body armor prepared from the fabric has the characteristics of being worn inside, breathable, sweat-absorbent, strong in protection effect and the like.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an elastic fiber fabric used for body armor and a preparation method thereof. Background technique [0002] Bulletproof vest, also known as bulletproof vest, bulletproof vest, bulletproof vest, bulletproof clothing, etc., is a kind of body protection equipment for individual soldiers. It is used to protect the human body from bullets or shrapnel. Body armor is mainly composed of two parts: a jacket and a bulletproof layer. Clothes are often made of chemical fiber fabrics. The bulletproof layer is made of metal (special steel, aluminum alloy, titanium alloy), ceramic sheet (corundum, boron carbide, silicon carbide, aluminum oxide), glass fiber reinforced plastic, nylon (PA), Kevlar (KEVLAR), ultra-high molecular weight polyethylene Fiber (DOYENTRONTEX Fiber), liquid protective materials and other materials constitute a single or composite protective structure. The bulletproof...
