Embodiment Construction
[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown, the present invention selects ultra-high molecular weight polyethylene fibers (ECPE), polypropylene fibers (ECPP), polyvinyl alcohol fibers (PVA) and polyacrylonitrile fibers as raw materials to prepare high-strength carbon fibers and yarns, and then obtain high-strength carbon fibers Stab-resistant fabric network, and the fibers and yarns in the fabric network are coated with a low-modulus and low-molecular-weight elastic material with an elastic modulus below 6000psi, and then the multi-layer fiber or yarn network is stacked at staggered angles to form Multiple layers of fabric.
[0028] See figure 2 , The coating treatment of the stab-resistant fabric network includes front and back coating treatment.
[0029] See image 3 , taking the production of stab-resistant carbon fiber fabrics by stacking fiv...

Abstract
The invention provides a high-count carbon fiber fabric applied to stab-resistant body armor field and a production method thereof. The fabric provided by the invention is composed of at least one layer of high-strength carbon fiber network or high-strength and high-modulus polyolefin yarn cross layered network, and the used fiber and yarn are prepared from ultra-high molecular weight ECPE fiber, ECPP fiber, PVA fiber and polyacrylonitrile fiber. The fineness of the fiber and yarn adopted by the fabric provided by the invention is not more than 500den, the fracture energy is more than 22J / g, and the tensile modulus is not less than 200g / den. To further optimize the performance of the stab-resistant fabric, the fineness of the fiber adopted by the invention reaches 300den and 250den, the tensile modulus is more than 1200g / den and 1800g / den. In addition, the fiber and yarn involved in the invention are also selectively coated with a low-modulus and low-molecular weight elastic material with an elastic modulus of less than 6000psi to further enhance the stab-resistant performance of the carbon fiber fabric.
Description
technical field [0001] The invention relates to the production field of anti-stab clothing of protective materials, in particular to a carbon fiber fabric with high count and soft characteristics and a production method thereof, which is applied to anti-stab clothing. Background technique [0002] Stab-resistant garments such as stab-resistant vests are generally composed of high-strength and high-modulus fibers such as aramid fibers (such as aramid fibers), nylon fibers, and glass fibers. At present, various protective materials such as stab-proof vests or part of stab-proof clothing are obtained by knitting or weaving these high-strength and high-modulus fibers. [0003] Whether the stab-proof material has excellent stab-proof performance is related to the following factors: (1) The raw materials used, the stab-proof performance of different fibers are different, the stab-proof performance of different varieties of the same fiber is also different, the melting point of the...
