[0024] 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.

[0025] The present invention provides Figure 1-2 A dustproof fabric shown includes a fabric base layer 1, and a flame retardant layer 2 is fixedly connected to the top of the fabric base layer 1. The flame retardant layer 2 is made of aramid fiber. Aramid fiber usually has the characteristics of high strength and high modulus. At the same time, aramid fiber can maintain good performance at high temperatures. Aramid fiber has good fire resistance. Aramid fiber can remain stable in corrosive environments such as strong acids and strong alkalis, and is not corroded by chemicals. Aramid fiber also has good insulation and aging resistance, and can maintain its stable performance for a long time. Aramid fiber also has the characteristics of antibacterial and corrosion resistance, which is beneficial to increase the flame retardant properties of the textile fabric base layer 1, facilitates improving the safety of the use of the textile fabric base layer 1, and avoids the random burning of the textile fabric base layer 1.

[0026] Furthermore, an elastic layer 3 is provided on the top of the fabric base layer 1, and a tensile layer 7 is provided below the fabric base layer 1. The elastic layer 3 includes a first reinforcement belt 32, and a second reinforcement belt 33 is provided at the bottom of the first reinforcement belt 32. The first reinforcement belt 32 and the second reinforcement belt 33 are beneficial to increasing the diagonal tension capacity of the fabric base layer 1, and thus are beneficial to protecting the fabric base layer 1 against deformation, so as to increase the service life of the fabric. The first reinforcement belt 32 and the second reinforcement belt 33 are used for diagonally reinforcing and supporting the fabric base layer 1. A connecting belt 31 for horizontally reinforcing the first reinforcement belt 32 and the second reinforcement belt 33 is provided on the side of the second reinforcement belt 33. The connecting belt 31 is beneficial to pulling between adjacent first reinforcement belts 32 and second reinforcement belts 33, and thus is beneficial to increasing the horizontal tension between adjacent first reinforcement belts 32 and second reinforcement belts 33, facilitating the increase of the stability of the fabric base layer 1 during use. The bottom end of the first reinforcement belt 32 is fixedly connected to the top end of the second reinforcement belt 33, and the first reinforcement belt 32 and the second reinforcement belt 33 are arranged in an interleaved manner. The connecting belt 31 is fixedly connected between adjacent first reinforcement belts 32 and second reinforcement belts 33. Both the connecting belt 31 and the first reinforcement belt 32 are made of spandex. Spandex fibers have the characteristics of low sensitivity, good air permeability, and high elasticity. The elastic elongation of spandex fibers is high, higher than that of nylon high-elastic yarns. The resilience of spandex fibers is high. Spandex fibers have excellent elasticity, corrosion resistance, heat resistance, tear resistance, acid and alkali resistance, sweat resistance, dry-cleaning resistance, and wear resistance. Spandex fibers have the characteristics of high breaking elongation and high recovery rate, and thus are beneficial to increasing the elastic performance of the textile fabric base layer 1, facilitating the increase of the tensile strength of the textile fabric base layer 1, so as to increase the flexibility of the textile fabric base layer 1 and improve the service strength of the textile fabric base layer 1. The second reinforcement belt 33 is made of polyester. Polyester fibers are also known as polyester fabrics. Polyester fabrics have relatively high strength and elastic recovery ability. Therefore, polyester fibers have the characteristics of being firm and durable, wrinkle-resistant and non-ironing. Polyester fibers have good light resistance. The wear resistance of polyester fibers is good. At the same time, polyester fibers have a strong luster, stable colors after dyeing, adjustable hues, and are not easy to fade, and thus are beneficial to increasing the elastic performance of the second reinforcement belt 33.

[0027] Specifically, the top end of the flame retardant layer 2 is fixedly connected to the elastic layer 3, the top end of the elastic layer 3 is fixedly connected with a wear-resistant layer 4, and a breathable layer is fixedly connected between the flame retardant layer 2 and the elastic layer 3. The breathable layer is made of hydrophilic porous polyethylene film. The hydrophilic porous polyethylene film has excellent breathability and hydrophilic properties. The hydrophilic porous polyethylene film can not only allow gas to pass through, but also effectively adsorb moisture to keep the film in a moist state. The hydrophilic porous polyethylene film has the characteristics of wear resistance, high modulus and high toughness. The top end of the wear-resistant layer 4 is fixedly connected with an antistatic layer 5. The antistatic layer 5 is made of antistatic cloth. The antistatic cloth uses polyester as the main body and is woven with conductive fibers in the warp or weft direction through a special process. It has an efficient antistatic function. Antistatic can effectively reduce static electricity accumulation, prevent charge accumulation on the human body, and reduce the occurrence of electric shock. It has good dust-proof performance. The antistatic cloth not only has an antistatic function, but also can effectively prevent the shedding of fabric fibers and the seepage of fine dust particles from the fabric gaps. The antistatic cloth has the characteristics of softness, thinness, smoothness and clear texture. The surface of the antistatic cloth is soft, easy to wear and wash, high temperature resistant and chemically stable. The antistatic cloth has the property of being high temperature resistant and can be used in high temperature environments. At the same time, the antistatic cloth has stable chemical properties, is resistant to washing and is not easily affected by chemical substances, which is convenient for dust protection on the fabric surface. The wear-resistant layer 4 is made of polyester fiber. The polyester fiber is polyarylate fiber, which has small water absorption, good anti-creep and wear resistance. At the same time, the polyester fiber has excellent wrinkle resistance, elasticity and dimensional stability, and the polyester fiber has good electrical insulation performance, resistance to sunlight, resistance to friction, is not mildewed or moth-eaten, has good resistance to chemical reagents, and can withstand weak acids and weak bases. Therefore, it is beneficial to increase the wear resistance of the textile fabric base layer 1 and improve the service life of the textile fabric base layer 1.

[0028] Specifically, an antibacterial layer 6 is fixedly connected to the bottom end of the fabric base layer 1. The bottom end of the antibacterial layer 6 is fixedly connected to a tensile layer 7. The bottom end of the tensile layer 7 is fixedly connected to a soft layer 8. The antibacterial layer 6 is made of bamboo fiber. Bamboo fiber has high strength and wear resistance. The tensile fracture strength of bamboo fiber is higher than that of viscose fiber. The tensile fracture elongation rate of bamboo fiber is high. At the same time, bamboo fiber has good air permeability, which can allow the skin to breathe and keep the skin dry. The moisture absorption performance of bamboo fiber is excellent, and it can absorb more water than its own weight. Bamboo fiber has the characteristic of natural antibacterial property. There is a natural antibacterial substance contained in bamboo fiber, which can effectively kill bacteria and inhibit the growth of bacteria. It is gentle and skin-friendly, and thus is beneficial to increasing the antibacterial performance of the textile fabric base layer 1 and facilitating the protection of the user's skin. The tensile layer 7 is made of nylon fiber. Nylon fiber is also known as polyamide fiber. Nylon fiber is a synthetic fiber. The density of nylon fiber is small, it is light in weight but high in strength, stronger than the strength of steel, and has high tensile strength and shear strength. The corrosion resistance of nylon fiber is good and it is not corroded by acids, alkalis and organic substances. Nylon fiber has high elasticity and can quickly return to its original shape. The volume resistance of nylon is very high and the breakdown voltage resistance is high. Nylon fiber is an electrical and electrical insulation material. The resistance of nylon fiber to ultraviolet rays is relatively strong and it is not easy to fade. The melting point of nylon fiber is relatively high and it can withstand high temperatures and is not easy to melt. Thus, it is beneficial to increasing the tensile performance of the textile fabric base layer 1. The soft layer 8 is made of pure cotton. The pure cotton material has the characteristics of comfort, durability, good air permeability and warmth retention. The pure cotton fabric is soft and comfortable, relatively durable, not easy to wear and deform. At the same time, since cotton fiber is a poor conductor of heat and electricity, the thermal conductivity coefficient is extremely low. Cotton fiber itself has porosity, high elasticity, and a large amount of air can be accumulated between the fibers. Thus, it is beneficial to increasing the softness of the textile fabric base layer 1 to improve the comfort of the user when wearing.

[0029] A preparation process of a dust-proof fabric, which includes performing a preparation operation on a fabric base layer 1, and separately preparing a flame-retardant layer 2, an elastic layer 3, a wear-resistant layer 4, an antistatic layer 5, an antibacterial layer 6, a tensile layer 7, a soft layer 8 and a breathable layer respectively. After the production is completed, a standby operation is carried out. When preparing the elastic layer 3, spandex fiber is used as the base layer, and the spandex fiber is woven and the polyester fiber is woven to form a first reinforcement belt 31, a second reinforcement belt 33 and a connecting belt 31. Then, the first reinforcement belt 32, the second reinforcement belt 33, the connecting belt 31 and the spandex fiber base layer are subjected to a lamination and bonding operation. When preparing the breathable layer, the porous polyethylene film is impregnated in an ammonium persulfate solution with a concentration of 2.5-5%, the heating temperature is set at 75-80°C and impregnated for 1.5-2 hours, ultrasonically washed, filtered and dried to obtain a hydrophilic porous polyethylene film for standby. Then, the flame-retardant layer 2, the elastic layer 3, the wear-resistant layer 4, the antistatic layer 5, the antibacterial layer 6, the tensile layer 7, the soft layer 8 and the breathable layer are respectively subjected to a lamination and bonding operation with the fabric base layer 1, thus completing the preparation of the fabric.
