Embodiment 1

[0036] A method for preparing a composite multi-layer bulletproof and stab-resistant fabric is formed by superimposing and sewing five layers of sheets, and the sheets are prepared by the following method:

[0037] (1) First make polyethylene fibers with polyethylene with a viscosity-average molecular weight of 3,000,000;

[0038] (2) Put the polyethylene fiber into the polyvinyl butyral resin-waterborne polyurethane resin mixed solution again, impregnate and dry to obtain the pretreated polyethylene fiber;

[0039] (3) Then the pretreated polyethylene fibers are twisted to form warp yarns and weft yarns, and then warp yarns and weft yarns are interwoven into plain weave fabrics;

[0040] (4) Spray carbon nanotubes evenly on both surfaces of the plain weave fabric, transfer it to a evacuated airtight space, introduce a methane-hydrogen gas mixture with a volume ratio of 4:1, and treat it with 400W microwave for 3 minutes to obtain a surface-modified fabric ;

Abstract

The invention provides a composite multi-layer bulletproof and stab-resistant fabric and a preparation method thereof. The composite multi-layer bulletproof and stab-resistant fabric is obtained by overlapping and sewing sheets. The sheets are prepared through the following method of preparing polyethylene fibers from polyethylene with a viscosity-average molecular weight of 2-3 million; putting polyethylene fibers into the polyvinyl butyral resin-waterborne polyurethane resin mixed solution, dipping and drying to obtain pretreated polyethylene fibers; twisting the pretreated polyethylene fibers to form warp yarns and weft yarns, and interweaving the warp yarns and the weft yarns to form a plain weave fabric; uniformly spraying carbon nanotubes on two surfaces of the plain weave fabric, transferring the plain weave fabric into a vacuumized closed space, introducing methane-hydrogen mixed gas, and carrying out microwave treatment to obtain a surface-modified fabric; and finally, putting the surface-modified fabric into impregnation liquid, impregnating, drying and hot-pressing to obtain the sheets. The bulletproof and stab-resistant fabric has good bulletproof and stab-resistant effects and is good in softness.

Description

technical field [0001] The invention relates to the technical field of protective products, in particular to a composite multi-layer bulletproof and stabproof fabric and a preparation method thereof. Background technique [0002] The existing individual protective components (or anti-riot clothing) mainly rely on the combination of external injection molded parts (made of high-quality high-strength engineering plastics) and buffer lining (made of soft energy-absorbing materials) to resist external Hitting energy has certain limitations in the degree of protection of vital organs of the body. It is only protected by a cloth of a certain thickness (for example: general nylon fiber fabric), and this protective clothing is difficult to ensure the safety of the lives of national staff and the masses. [0003] Bullet-proof and stab-proof materials have obvious differences in protection mechanism. The main energy-absorbing modes of bullet-proof materials are fiber elastic deformat...
