Description

Technical Field

[0001] The present invention relates to the technical field of fabrics, and specifically to a waterproof, breathable and antibacterial functional fabric and a preparation method thereof. Background Art

[0002] Waterproof and breathable fabrics are generally used in the production of mountaineering clothes. When people exercise for a long time, sweat is easily generated. If sweat is not discharged for a long time, bacteria are likely to breed, which is unhealthy for the skin. Adding antibacterial ability to the fabric can reduce the growth of bacteria.

[0003] The defects of the existing fabrics are as follows:

[0004] 1. The prior art JP2002339548A discloses a fabric. This technology does not have bactericidal ability. When exercising and sweating, bacteria are likely to breed in a humid environment, which is unhealthy for the skin. Therefore, a waterproof, breathable and antibacterial functional fabric with bactericidal ability is needed to solve this problem.

[0005] 2. The prior art JP2001260109A discloses a fabric. This technology does not have a silver ion membrane. When setting a silver ion membrane in this fabric, the effect of reducing the loss of silver ions when the fabric is soaked in tap water for a long time cannot be achieved. Silver ions continuously combine with chloride ions in tap water to form silver chloride precipitate, thereby quickly reducing the silver content of the silver ion membrane and reducing the bactericidal effect. Therefore, a waterproof, breathable and antibacterial functional fabric with antibacterial ability and less silver ion loss when soaked in tap water is needed to solve this problem.

[0006] 3. The prior art JPH09207276A discloses a fabric. This technology does not have a light-transmitting and light-reflecting structure. When silver chloride precipitate adheres to the fabric, since the inner layer of the fabric cannot be irradiated by light, the silver chloride in the inner layer of the fabric is not easily decomposed into silver and chlorine gas, resulting in the inability to reuse silver ions and low silver ion utilization rate. Therefore, a waterproof, breathable and antibacterial functional fabric with a light-transmitting structure that enables the silver chloride in the inner layer of the fabric to be decomposed by light is needed to solve this problem.

[0007] 4. The prior art CN112297575B discloses a waterproof and breathable fabric and a preparation method thereof. When setting a silica gel desiccant to absorb water in this fabric, if it is necessary to dry the water in the silica gel desiccant, since the fabric does not have a heat-absorbing structure, it cannot release heat to heat the desiccant at night, and thus the evaporation efficiency of the water in the desiccant cannot be improved at night. Therefore, a waterproof, breathable and antibacterial functional fabric with a heat-absorbing effect that can release heat at night to improve the evaporation efficiency of the water in the desiccant is needed to solve this problem. Summary of the Invention

[0008] An object of the present application is to provide a waterproof, breathable and antibacterial functional fabric and a preparation method thereof, which can solve the technical problems raised in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solution: a waterproof, breathable and antibacterial functional fabric, which sequentially includes a waterproof and breathable layer, a reflective layer, a plastic film layer, a first air-permeable groove, a through groove, an antibacterial film, a drying ball, a heat storage strip, a fiber layer and a light-transmitting groove from bottom to top. The reflective layer is arranged on the top of the waterproof and breathable layer, the plastic film layer is arranged on the top of the reflective layer, the top of the plastic film layer is penetrated with the first air-permeable groove, the top of the plastic film layer is penetrated with the through groove, and the first air-permeable groove and the through groove are distributed at intervals. The antibacterial film is arranged inside the through groove, a plurality of drying balls are arranged inside the through groove, and the drying balls are located above the antibacterial film. The heat storage strip is arranged on the top of the reflective layer by gluing, and the heat storage strip is located inside the first air-permeable groove. The fiber layer is arranged on the top of the plastic film layer, and a plurality of light-transmitting grooves are penetrated through the top of the fiber layer.

[0010] Preferably, the waterproof and breathable layer is a waterproof and breathable membrane.

[0011] Preferably, the reflective layer is a reflective cloth.

[0012] Preferably, the drying ball is a spherical silica gel desiccant.

[0013] Preferably, the material of the plastic film layer is one of polyethylene film or polypropylene film.

[0014] Preferably, the material of the fiber layer is one of cotton fiber cloth, linen fiber cloth, polyester fiber cloth or nylon fiber cloth.

[0015] Preferably, the heat storage strip is a magnesium oxide strip.

[0016] Preferably, the antibacterial film is a silver ion film.

[0017] Preferably, the preparation method of the waterproof, breathable and antibacterial functional fabric is as follows:

[0018] S1. Place the waterproof and breathable membrane on the substrate to form the waterproof and breathable layer, then use a dotting machine to dot glue on the waterproof and breathable layer, and then stick the reflective cloth on the top of the waterproof and breathable layer to form the reflective layer;

[0019] S2. Use a punching machine to punch out the first air-permeable groove and the through groove on the top of the plastic film layer;

[0020] S3. Use a dotting machine to dot glue on the bottom of the plastic film layer, and then glue the bottom of the plastic film layer on the top of the reflective layer;

[0021] S4. Then use a dotting machine to dot glue on the bottom of the antibacterial film, and then glue the bottom of the antibacterial film to the top of the reflective layer, and the antibacterial film is located inside the through groove. Then place the drying balls inside the through groove;

[0022] S5. Punch a light-transmitting groove at the top of the fiber layer using a stamping machine;

[0023] S6. Then, apply glue on the top of the plastic film layer using a glue dotting machine, and then attach the fiber layer to the top of the plastic film layer.

[0024] Preferably, in step S6, the following steps are further included:

[0025] S61. Subsequently, apply glue on the reflective layer inside the light-transmitting groove using a glue dotting machine, and attach the magnesium oxide strip to the top of the reflective layer inside the light-transmitting groove to form a heat storage strip.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. The present invention is provided with a waterproof and breathable layer, which enables the fabric to have good waterproof ability, and by setting an antibacterial film, the fabric has good antibacterial ability.

[0028] 2. By setting the plastic film layer, through groove and drying ball in the present invention, after the fabric is soaked in water for a certain period of time, the volume of the drying ball absorbs water and expands, thereby blocking the top opening of the through groove, reducing the exchange of water inside the through groove with the outside water, and further reducing the loss of silver ions in the antibacterial film, so that the fabric can still have a certain antibacterial ability after multiple washes.

[0029] 3. By setting the reflective layer and light-transmitting groove in the present invention, when the fabric is exposed to the sun, sunlight can enter between the reflective layer and the fiber layer, so that silver chloride formed by the combination of silver ions in the fabric and chloride ions in tap water decomposes into silver and chlorine under the condition of light, so that silver can still have an antibacterial effect when encountering water, improving the utilization rate of silver.

[0030] 4. By setting a heat storage strip in the present invention, heat can be stored during exposure to the sun, and then at night, the heat can still be released to heat the drying ball, evaporating the water in the drying ball and improving the evaporation effect of water.

[0101]
