Embodiment 1

[0048] Continuous production method

[0049] First, weigh 10Kg of modified acrylate adhesive, add 1Kg of water, mix the glue thoroughly, and pour it into the glue tank for later use.

[0050] Install the aramid fiber package on the creel. After the fiber is drawn out from the creel, it passes through the infrared yarn breakage automatic stop control device. On the premise of ensuring that each fiber is in a normal state, the fiber enters the screen sealing reed module to realize the positioning of the fiber bundle in the facade space. The fiber bundle enters the surface density control module to realize the accurate positioning of the fiber bundle in the width direction. Afterwards, the precisely positioned fiber bundles enter the spreading module, so that the monofilaments of each bundle of fibers are evenly distributed within the width range to the greatest extent, and the spreading is realized. The evenly spread tow is sent to the gluing module for gluing to achieve unifo...

Embodiment 2

[0056] Sheet device manufacturing method

[0057] First weigh 1Kg of the modified acrylate adhesive and pour it into a plastic box for later use.

[0058] The aramid fiber is wound in parallel on the winding machine, and then the fiber is immersed in the above glue solution, and the unidirectional fiber prepreg is prepared by spinning through a specific spinning equipment. In this example, the above-mentioned adhesive is used. After dipping, spread the glue evenly with a squeegee, and dry it under a 50°C electric resistance wire. After the unidirectional fiber prepreg is completely dry, cut it at 0° and 45° , and then laminate the cut unidirectional fiber prepreg according to [0° / 45° / 90° / 135°], use adhesive or film to bond each layer, and use a press to press , the pressing process conditions are: temperature 120-140°C, pressure 10-20MPa, pressing time depends on the thickness of the sample, you can get [0° / 45° / 90° / 135°] four-layer bulletproof anti-stab non-weft cloth.

Embodiment 3

[0061] Sheet device manufacturing method

[0062] First weigh 1Kg of the modified acrylate adhesive and pour it into a plastic box for later use.

[0063] The aramid fiber is wound in parallel on the winding machine, and then the fiber is immersed in the above glue solution, and the unidirectional fiber prepreg is prepared by spinning through a specific spinning equipment. In this example, the above-mentioned adhesive is used. After dipping, spread the glue evenly with a squeegee, and dry it under a resistance wire at 50°C. After the unidirectional fiber prepreg is completely dry, rotate the cloth sample by 90°, and use The method is to carry out orthogonal compounding of the fiber filaments and the sample fiber filaments, and obtain two layers of interlaced fabric samples. The resulting product structure is correspondingly [0° / 90°]. Cut the fabric sample into a 400mm×400mm square fabric sample, stack the two layers of fabric samples in the direction of [0° / 90°, 0° / 90°], put...

Abstract

The invention provides multi-angle bulletproof and puncture-proof no-weft cloth, and relates to the field of individual protection. The multi-angle bulletproof and puncture-proof no-weft cloth is mainly formed by compositing a plurality of layers of unidirectional fiber preimpregnated materials through different angles, and every two layers of unidirectional fiber preimpregnated materials are bonded through tackiness agents or adhesive films. According to the no-weft cloth, each layer of the cloth comprises at least one layer of unidirectional fiber preimpregnated materials, wherein the surface density of the each layer of unidirectional fiber preimpregnated materials is 55 g / m<2>+ / -5 g / m<2> or 110 g / m<2>+ / -5 g / m<2>. The invention further provides a manufacturing method of the multi-angle bulletproof and puncture-proof no-weft cloth. Puncture-proof no-weft clothes produced by the multi-angle bulletproof and puncture-proof no-weft cloth is high in safety margin and light, safe reliability of fighting personnel can be obviously improved, meanwhile, fighting efficiency of the fighting personnel is improved, and loads of the fighting personnel are reduced.

Description

Technical field: [0001] The invention relates to a multi-angle bulletproof and stab-proof non-weft fabric, and also relates to a preparation method for a multi-angle bullet-proof and stab-proof non-weft fabric. Background technique: [0002] Personal protective equipment is used to ensure the safety of personnel in the army, armed police forces and special departments. The main products include body armor, stab-proof clothing, bullet-proof helmets and cut-resistant gloves. The above products only have a single protective function, or only have a bullet-proof function, or only have a stab-proof function, and are suitable for specific working environments. Therefore, seeking a balance between effective protection, flexibility and light weight, and achieving comprehensive protection performance on one product as much as possible has always been the goal pursued by researchers of personal protection products. [0003] US99802326.4 introduces a kind of anti-stab and bullet-proof...
