Description
Technical Field
The invention relates to the technical field of production of special high-strength bulletproof protection fabrics, in particular to a weaving treatment method for avoiding reduction of mechanical properties of high-strength fiber fabrics.
Background
The high-strength fiber, i.e. the high-strength and high-modulus fiber, is a synthetic fiber with the strength of more than 10CN/dkex and the modulus of more than 200 CN/dkex. For example, the strength of Kevlar (called aramid-1414 in China) fiber successfully developed in the United states is 5 times that of steel wire with the same mass. It has low density, only 1/6 of steel wire, and can transmit microwave. It can be used as the reinforcing material of aeronautical equipment. The high-strength and high-modulus carbon fiber is prepared by taking viscose fiber, acrylic fiber and asphalt fiber as raw materials and performing high-temperature carbonization and graphitization, and is widely applied to atomic energy, metallurgy and chemical industry.
At present, domestic special bulletproof protection fabrics have increasingly larger application requirements, and are generally woven by high-strength fibers through a weaving process. The high-performance fiber has poor pre-orientation due to high strength and high modulus, and the phenomena of monofilament breakage and more broken filaments generally exist in the production of the fiber, so that the weaving processing on a common loom is difficult; meanwhile, the woven high-strength fiber fabric can reduce the monofilament mechanical conductivity of the high-strength fiber to the maximum extent only by washing and deoiling after finishing; the traditional washing process has high acid-base concentration, so that the mechanical properties of the high-strength fibers are damaged to different degrees. How to provide a more effective design for the problems influencing the mechanical property of the high-strength fiber, thereby systematically improving the prevention of the reduction of the mechanical property of the high-strength fiber, forming industrial matching with high-strength fiber manufacturers, producing high-quality high-strength bulletproof protection fabrics with smooth cloth covers and unchanged strength, and becoming the thinking of people of the first generation.
