Problems solved by technology

Therefore, most of the existing double-proof clothing is the form of multi-structure superimposition and multi-material combination of the bullet-proof layer and the stab-proof layer, which has caused the double-proof clothing to have complicated procedures, heavy weight, and low wearing comfort.
At present, there is no literature report that aramid non-weft fabric has bulletproof function and stab resistance function at the same time.

Embodiment 1

[0017] The adhesive is compounded of water-based polyurethane and water-soluble amino resin, the amount of water-soluble amino resin added is 20% of the mass of water-based polyurethane, and then the overall solid content is adjusted to 40%. The prepared adhesive is directly applied to the aramid non-weft weaving machine for weaving. After completion, the cloth is subjected to subsequent pressing according to the previously described pressing process to obtain a surface density of 220g / m 2 Aramid non-weft fabric.

[0018] The bullet-proof and stab-proof tests were carried out on the aramid non-weft fabric, and the final conclusion is that 45 layers of the non-weft fabric are superimposed, and the bullet-proof meets the third-level standard in the "Police Body Armor" of the Ministry of Public Security GA141-2010, and the stab-proof meets the GA68-2008 The anti-stab standard in "Police Anti-stab Clothing". The overall protective layer density is 9.9Kg / m 2 .

Embodiment 2

[0020] The adhesive is composed of water-based polyurethane and water-based phenolic formaldehyde. The amount of water-based phenolic formaldehyde added is 40% of the mass of water-based polyurethane, and then 10% of the overall mass of amino resin is added. After stirring evenly, the final adhesive with a solid content of 35% is prepared. Carry out weaving and pressing according to above-mentioned steps afterwards, finally make surface density be 208g / m 2 The final weft-free fabric.

[0021] The bullet-proof and stab-proof tests were carried out on the aramid non-weft fabric. The final conclusion is that 38 layers of the non-weft fabric are superimposed, and the bullet-proof meets the secondary standard in the Ministry of Public Security GA141-2010 "Police Body Armor", and the stab-proof meets the GA68-2008 The anti-stab standard in "Police Anti-stab Clothing". The overall protective layer density is 8Kg / m 2 .

Abstract

The invention provides an aramid fiber non-woven fabric. The aramid fiber non-woven fabric has the dual functions of bullet and prick resistance. The aramid fiber non-woven fabric is obtained by performing spreading, coating and hot-air drying on aramid fiber and then performing a special pressing technology. An adhesive is one or more of waterborne polyurethane, waterborne phenolic aldehyde, waterborne epoxy and water soluble amino resin, the solid content is larger than or equal to 35%, and a secondary reaction can be performed under high temperature. The special pressing technology comprises a hot-pressing technology and a cold-pressing technology; the pressure of the hot-pressing technology is 2.5-15 MPa; the temperature is 125-170 DEG C, and the pressing time is 5-30 min; the pressureof the cold-pressing technology is 2.5-15 MPa; the temperature is room temperature, and the pressing time is 2-7 min. The aramid fiber non-woven fabric has the dual functions of bullet and prick resistance, certain layers are stacked so as to be directly applied to a dual-protection garment, the dual-protection garment has the advantages that the garment is made of uniform materials, and no bulletproof layer or anti-prick layer is arranged distinguishingly; the garment is made of the aramid fiber non-woven fabric, can be bent at any angle, and is comfortable to wear, low in mass and portable.

Description

Technical field: [0001] The patent of the present invention relates to the field of production and application of aramid non-weft fabric, and the field of personal protection, especially the field of protection that requires bulletproof and stab-proof. Background technique: [0002] Aramid fiber is an organic fiber composed of aromatic rings and amide bonds on the main chain of macromolecules, which was first developed by DuPont Company of the United States. It has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, and its toughness is 2 times that of steel wire. times, and the weight is only about 1 / 5 of steel wire. Therefore, aramid fiber is an ideal material for making soft body armor, stab-proof clothing, lightweight bullet-proof helmets, etc. [0003] Aramid non-weft fabr...
