Description

Technical Field

[0001] The invention relates to the technical field of nylon fabrics, in particular to a high-strength, wear-resistant and tensile-resistant military nylon printing and dyeing fabric and a preparation method thereof. Background Art

[0002] Nylon fabric has excellent high strength, wear resistance and tensile resistance. When dyeing nylon fabric, due to the dense surface of the nylon fiber in the fabric, the dye is not easy to penetrate into the interior of the nylon fiber, so the dye on the nylon fabric is easy to fall off. Nylon fabric is often used in military clothing, tents and awnings.

[0003] The defects of existing nylon fabrics are: 1. Prior art JP2002348772A discloses a method for refining nylon fabrics or knitted fabrics. When dyeing nylon fabrics with this technology, the dye in the nylon fabrics easily fades when exposed to water. Therefore, a high-strength, wear-resistant and tensile-resistant military nylon printing and dyeing fabric is needed to solve this problem.

[0004] 2. The prior art KR1020030068847A discloses a functional fabric with selectable color tones and a dyeing method thereof. This technology does not have the function of refracting and reflecting sunlight to reduce the damage of sunlight to nylon fabric. Nylon fabric is easily damaged and aged under long-term sunlight exposure. Therefore, a high-strength, wear-resistant and tensile-resistant military nylon printing and dyeing fabric that can refract and reflect light to reduce the damage of sunlight to nylon fabric is needed to solve this problem.

[0005] 3. The prior art KR200190291Y1 discloses nylon soft polyester fabric, which does not have a heat-insulating structure. The nylon fabric has poor heat-insulating ability and weak heat-insulating ability for the human body. Therefore, a high-strength, wear-resistant and tensile-resistant military nylon printing and dyeing fabric with good heat-insulating ability is needed to solve this problem.

[0006] 4. Prior art CN116065411B discloses a highly sun-resistant nylon printed fabric, which does not have the ability to store heat. When the temperature difference between day and night is large, it cannot absorb heat during the day and provide heat for people at night. Therefore, a high-strength, wear-resistant and tensile-resistant military nylon printed and dyed fabric with heat storage capacity that absorbs heat at high temperatures and provides heat at low temperatures is needed to solve this problem. Summary of the invention

[0007] One purpose of the present application is to provide a high-strength, wear-resistant and tensile-resistant military nylon printed and dyed fabric and a preparation method that can solve the technical problems raised in the prior art.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a high-strength, wear-resistant and tensile-resistant military nylon printed and dyed fabric, which includes, from bottom to top, a nylon layer one, a waterproof layer one, a heat storage layer, a waterproof layer two, a thermal insulation layer, a waterproof layer three, a nylon layer two and an acrylic particle layer, the thermal insulation layer is composed of a mixture of thermal insulation cotton and foam particles, and the nylon layer two is composed of nylon fabric, hot melt adhesive and dye.

[0009] Preferably, the nylon layer 1 is nylon fabric.

[0010] Preferably, the waterproof layer one, the waterproof layer two and the waterproof layer three are simultaneously one of polyethylene film, polyvinyl chloride film and polypropylene film.

[0011] Preferably, the foam particles in the thermal insulation layer are uniformly filled in the gaps of the thermal insulation wool, and the thermal insulation wool is one of glass wool, rock wool and asbestos.

[0012] Preferably, the preparation method of the nylon layer 2 is as follows: The nylon fabric is soaked in acetic acid for 20 minutes, then taken out and cleaned, the hot melt adhesive containing the ultraviolet absorber is melted and mixed with the dye, and then the hot melt adhesive mixed with the dye is sprayed on the acid-washed nylon fabric to obtain the product.

[0013] Preferably, the hot melt adhesive in the preparation method of the nylon layer is one of polyethylene hot melt adhesive and polypropylene hot melt adhesive.

[0014] Preferably, the average particle size of the acrylic particles is 2-4 mm.

[0015] Preferably, the heat storage layer material is one of paraffin and mutton fat.

[0016] Preferably, the preparation method of the high-strength, wear-resistant and tensile-resistant military nylon printed and dyed fabric is as follows: S1, placing nylon fabric on a substrate to form a nylon layer 1, and then gluing a polyethylene film onto the nylon layer 1 by hot melt adhesive to form a waterproof layer 1; S2, spreading molten paraffin on the first waterproof layer to form a heat storage layer, and then after the paraffin solidifies, spreading a polyethylene film on the heat storage layer to form a second waterproof layer; S3, sprinkle the foam particles on the thermal insulation cotton, and then vibrate the thermal insulation cotton to make the foam particles fill the gaps in the thermal insulation cotton, and then spread the thermal insulation cotton filled with foam particles on the second waterproof layer to form a thermal insulation layer; S4, then glue the polyethylene film onto the insulation layer by hot melt glue dispensing to form a waterproof layer three; S5. Soak the nylon fabric in acetic acid for 20 minutes, then take it out and clean it, then melt the polyethylene hot melt adhesive and mix it with the dye, then spray the hot melt adhesive with the mixed dye on the acid-washed nylon fabric, and then lay the nylon fabric sprayed with the hot melt adhesive dye on the waterproof layer three to form the nylon layer two.

[0017] Preferably, the following steps are also present in S5: S51. After the hot melt adhesive mixed with dyes is sprayed on the acid-washed nylon fabric, acrylic particles are evenly sprinkled on the nylon fabric to form an acrylic particle layer.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can prevent the dye from fading easily during washing by mixing the dye with the hot melt adhesive and then spraying the mixture on the acid-washed nylon fabric, thereby avoiding the situation where the dye is easily shed from the nylon fabric caused by directly spraying the dye on the nylon fabric, so that the nylon fabric has excellent wear resistance, high strength and tensile resistance while having the property of not fading for a long time.

[0019] 2. The present invention can absorb ultraviolet rays by arranging an ultraviolet absorber in the nylon layer 2, thereby reducing the damage of ultraviolet rays to the hot melt adhesive in the nylon layer 2. The acrylic particles arranged in the nylon layer 2 can reflect and refract light under sunlight, thereby reducing the ability of light, reducing the damage of light to the nylon fabric and hot melt adhesive in the nylon layer 2, and making it more difficult for the dye to be separated from the nylon layer 2.

[0020] 3. The present invention arranges foam particles to be filled into the thermal insulation cotton, so that the thermal insulation layer in the composite nylon fabric is not easily squeezed and deformed, and the air in the thermal insulation layer is more difficult to circulate, so that the composite nylon fabric has a better thermal insulation ability.

[0021] 4. The heat storage layer of the present invention enables the fabric to absorb heat and release heat to slow down the cooling rate when the temperature is low, so that the fabric can absorb heat during the day and release heat at night to keep people warm in an environment with a large temperature difference between day and night.

[0043] Performance Testing: 1. Pigment fading detection: The product of each embodiment is placed in a stirring device for washing and stirring for 1 hour, and then taken out to observe whether the product fades; 2. Heat preservation ability test: Under a temperature of 25 degrees Celsius, the product of each embodiment was used to cover different basins, and then a heating lamp was used to irradiate the product above the basin. After 1 hour, a thermometer was used to test the air temperature inside the basin.

[0044] Test data of each embodiment under the same test conditions Embodiment 1 Embodiment 2 Embodiment 3 Embodiment 4 Embodiment 5 Embodiment 6 Is the color fading? no no no no no yes Temperature (℃) 29 27 32 48 28 28 It can be known from the experimental data that by mixing the dye with the hot melt adhesive and spraying it on the acid-washed nylon fabric, the dye is not easy to fade during the washing process.
