Embodiment 1

[0028] An electromagnetic shielding body armor, comprising an outer surface layer 1, a bulletproof layer 2 and an inner liner 3, such as figure 1 shown. 1 The outer surface layer 1 is composed of a scale-like structure of ferrite fiber textiles that can absorb waves and shield, especially a unique three-dimensional textile pattern structure that greatly increases the electromagnetic shielding performance, such as Figure 4 shown. The bulletproof layer 2 is composed of 4 kevlar fibers 4 and ultra-high molecular weight polyethylene fibers 5 twisted and superimposed with no less than 6 layers of fibers tightly compounded. The structure of the twisted fibers is as follows: figure 2 As shown, it has high protection performance, effective bulletproof and shockproof, and has good sports performance.

[0029] The inner lining layer 3 is woven from polylactic acid fiber, which has good bacteriostasis, flame retardancy, and heat resistance, is comfortable and has no toxic side effect...

Embodiment 2

[0032] An electromagnetic shielding bulletproof vest comprises an outer surface layer, a bulletproof layer and an inner lining layer. The outer surface layer is composed of a wave-absorbing and shielding ferrite fiber woven scale structure, the bulletproof layer is made of kevlar fiber and ultra-high molecular weight polyethylene fiber twisted tightly, and the inner lining layer is made of polylactic acid Fibers are woven.

[0033] Among them, the scale-like structure is a three-dimensional shell flower weaving pattern structure. Use a 16-gauge 1.50mm needle to knit three rows with flat stitches, and weave the scale pattern from the third row. Each scale is completed with 21 stitches. Leave one flat stitch between the scale patterns, and 6 flat stitches divide the 15 reverse stitches evenly so that they are arranged radially. After 7 circles, hook into a pattern, and then start to add thread from the main needle, the bottom is big and the top is small, and so on. The wave-ab...

Abstract

The invention relates to electromagnetic shielding body armor. The electromagnetic shielding body armor comprises an outer surface layer, a bulletproof layer and a lining layer, wherein the outer surface layer is made up of a scale-shaped structure spun by fibers capable of absorbing wave to shield ferrite; the bulletproof layer is tightly compounded from aromatic polyamide fibers and fibers twisted by ultra-high molecular weight polyethylene fibers; and the lining layer is formed by spinning polylactic acid fibers. The body armor is strong in bullet penetrating resistance, is various in function, has the electromagnetic shielding effect, and improves special environmental performances of the body armor. Especially, sweat-absorbing lining formed by spinning the polylactic acid fibers has very good bacteria resistance and heat resistance, and is comfortable and free of toxic and side effect, so that the problem that the body armor is uncomfortable to wear as a result of sweat is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of clothing, in particular to an electromagnetic shielding body armor. Background technique [0002] With the development of science and technology and the rise of new composite materials, the performance of body armor as a protective product has also been greatly improved since its inception. As a protective product, the core performance that body armor should have first is bulletproof performance. At the same time, as a functional garment, it should also have certain clothing performance. The bulletproof performance of body armor is mainly reflected in two aspects: on the one hand, it is bulletproof fragments. The high-speed fragments produced by the explosion of various explosives such as bombs, mines, shells and grenades are one of the main threats on the battlefield; Non-penetrating damage: After the bullet hits the target, it will produce a great impact force, and the damage caused by this impact forc...
