[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present invention provides Figure 1-2 The textile fabric shown has good radiation protection and air permeability, comprises an outer fabric 1 and an inner fabric 2, an anti-radiation layer 3 is arranged between the outer fabric 1 and the inner fabric 2, a connecting layer 4 is arranged between the outer fabric 1 and the anti-radiation layer 3 and between the anti-radiation layer 3 and the inner fabric, and the outer fabric 1, the inner fabric 2 and the anti-radiation layer 3 are interwoven with each other in a horizontal warp and vertical weft manner.

[0027] Furthermore, the outer fabric 1 is made of polyurethane fiber and tetrafluoroethylene fiber interwoven with each other, and the mass ratio of polyurethane fiber to tetrafluoroethylene fiber of the outer fabric 1 is 8:1.5. The yarn count of the outer fabric 1 is 90-95 metric deniers. The polyurethane fiber has high strength and elastic recovery ability, and can be stretched and bent well, making the clothing tough and durable, and also easy to wash and maintain. Compared with polyester fiber, polyurethane fiber performs better at high temperatures and has certain heat resistance. Polyurethane fiber has good light resistance, especially behind glass, the light resistance is close to acrylic fiber, which means that they can maintain a good appearance in outdoor environments. Polyurethane fibers can resist corrosion from chemicals such as acids and alkalis, and are not easily damaged by mold and insects, which makes them suitable for the production of a variety of clothing and personal items; tetrafluoroethylene fiber is a polyolefin fiber made from polytetrafluoroethylene, which is spun or made into a film and then cut or fibrillated. It has extremely high temperature resistance and can work continuously in the temperature range of -200C to +260℃, which can meet the needs of many high-temperature working environments. It has excellent chemical inertness and can resist corrosion from many chemical substances such as acids and alkalis, making it widely used in many chemical processes. And its molecular structure is stable, with high resistivity and extremely low conductivity, making it an ideal electrical insulating material. It is widely used in the fields of electronic components and insulating materials. It has high strength and elongation, good chemical stability, and better corrosion resistance than other synthetic fibers. It has good weather resistance and flex resistance. It can make up for the shortcomings of each other when paired with polyurethane fibers, making the performance of the fabric better.

[0028] Furthermore, the inner fabric 2 is blended from polyester and nylon, the mass ratio of polyester to nylon is 7:3, the yarn count of the inner fabric 2 is 70-80 metric, the elasticity of polyester is close to that of wool, and when stretched by 5%-6%, it can almost completely recover. After repeated rubbing of the polyester fabric, it can quickly recover its original shape without leaving wrinkles, and the elastic modulus is 22-141cN / dtex, which is 2-3 times higher than nylon, which is unmatched by other fabrics. Polyester fabric has good heat resistance and strong plasticity. The biggest advantage of polyester fabric is that it is not easy to deform and wrinkle, and has low hygroscopicity. Its wet strength is basically the same as its dry strength. The impact resistance is 4 times higher than that of nylon and 20 times higher than that of viscose fiber; polyester fabric is a kind of chemical fiber clothing fabric used very much in daily life. The major types of polyester include short fibers, stretched yarns, textured yarns, decorative filaments, industrial filaments and various differentiated fibers. The development of polyester high moisture absorption, perspiration, and quick-drying fabrics is of great significance to the improvement of clothing comfort. It is very suitable for high-competitive sportswear, workwear under high temperature and high humidity working conditions, outdoor clothing, underwear and other fields. Nylon yarn has high mechanical strength, good toughness, high tensile and compressive strength, higher tensile strength than metal, and comparable to metal in compressive strength, but its rigidity is not as good as metal. The tensile strength is close to the yield strength, which is more than double that of ABS. It has strong absorption capacity for impact, stress and vibration, and its impact strength is much higher than that of general plastics, and is better than acetal resin. It has outstanding fatigue resistance. The parts can still maintain the original mechanical strength after repeated bending. It is also corrosion-resistant, very resistant to alkali and most salt solutions, and also resistant to weak acids, motor oil, gasoline, aromatic compounds and general solvents. It is inert to aromatic compounds. Nylon yarn makes the surface of the fabric smooth, with a small friction coefficient, wear resistance, and more comfortable fit to the human body. It can be machine washed, and the drying time is three times faster than cotton. It only needs slight ironing or no ironing, is not easy to deform, and has significant wrinkle resistance.

[0029] Furthermore, the radiation protection layer 3 mainly uses metal microfilaments with a diameter between 3-50 microns to spin metal microfilament mesh fabrics. The yarn count of the radiation protection layer 3 is 40-50 metric counts. The metal wire cloth fabric has excellent corrosion resistance and can maintain a long service life in different corrosive media. For example, it can be used normally in corrosive media such as acid, alkali, and salt. The metal wire cloth fabric has excellent high temperature resistance and can maintain good physical and mechanical properties under high temperature conditions. The metal wire cloth fabric has excellent flame retardancy and is not easy to burn even in high temperature environments, which has a good effect on fire prevention. Therefore, the metal wire cloth fabric is often used in the fields of fire retardant materials, building insulation materials, etc., and the surface of the fabric has a metallic luster, flickers faintly, and changes with the change of the light source. The metal filaments have special rigidity and variable bending, so the fabric has a special variable shape memory wrinkle effect.

[0030] Furthermore, the connecting layer 4 is a mesh cloth made of chemical fiber blending. The mesh cloth generally uses 40-45 yarns. The mesh cloth has good air permeability and moderate adjustment ability. The three-dimensional mesh structure makes it called a breathing network. Compared with other plain woven fabrics, the mesh cloth has better air permeability. Through the air circulation in the air, the surface remains comfortable and dry, and the mesh structure of the mesh cloth is formed at high temperature during the production process. When subjected to external force, it can extend in the direction of the force. When the tension is reduced, the net can return to its original shape. The material can not only maintain a certain elongation in the horizontal and vertical directions, but also will not loosen or deform. The mesh fabric is extracted from petroleum by thousands of polymer synthetic fiber yarns. The weaving method is not only strong, but also can withstand high-intensity tension and tearing, and is smooth and comfortable. Multiple connecting layers 4 are connected to the outer fabric 1 or the inner fabric 2 by sewing, and multiple connecting layers 4 are connected to the outer fabric 1 or the inner fabric 2 by sewing. The mesh cloth is used to provide gaps between the outer fabric 1, the inner fabric 2 and the anti-radiation layer 3, so as to further improve the overall air permeability and moisture absorption of the fabric. By arranging multiple layers of mesh cloth inside the fabric, the fabric can be filled with gaps, which facilitates the smooth circulation of air when worn, and makes the fabric have good air permeability.

[0036] Two connecting layers 4 are placed between the outer fabric 1, the inner fabric 2 and the radiation protection layer 3 respectively, and the multiple layers of fabric are sewn together to form a qualified fabric;

[0037] The sewn fabric is dipped in a waterproofing solution with a pressure of 1.5-2kg / cm2 and a liquid rate of 75-78%.
