Description

Technical Field

[0001] The invention relates to the technical field of graphene fabrics, and in particular to a preparation process of a three-in-one graphene hydrophilic skin velvet fabric. Background Art

[0002] The comfort of fabrics represents the comfort of wearing, and warmth retention is one of the important properties of clothing fabrics. Good warmth retention can resist the loss of human body heat and maintain balanced human body temperature. Existing graphene aerogel thermal insulation fabrics have the defects of simple and single fabric structure in most cases, which leads to poor warmth retention effect of the fabrics. After long-term use, the existing graphene fabrics will cause pilling on the surface of the fabrics due to cleaning and friction, affecting the warmth retention effect. Moreover, after long-term wearing, since the fabrics need to face various deformations during wearing, once the elasticity of the fabrics cannot meet the recovery after deformation, the fabrics will become debonded and loose at the folds, resulting in poor warmth retention and comfort of the fabrics. Therefore, the softness and elasticity of the fabrics also have an important influence on their subsequent warmth retention effect. This requires the fabrics themselves to have good softness and elasticity to ensure the comfort of the fabrics. Therefore, a preparation process of a three-in-one graphene hydrophilic velvet fabric is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a three-in-one graphene hydrophilic skin velvet fabric preparation process to solve the problem of maintaining elasticity of the fabric in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A three-in-one graphene hydrophilic skin velvet fabric preparation process comprises the following steps:

[0006] S1, pre-treated graphene fabric;

[0007] S2, pre-treated elastic membrane;

[0008] S3, pre-treatment glue;

[0009] S4, applying glue to the elastic film and the graphene fabric with a glue coating roller, and applying glue to the contact surface between the elastic film and the graphene fabric;

[0010] S5. The elastic film and graphene fabric after glue coating are naturally dried in the workshop.

[0011] To implement the above technical solution, the graphene fabric is leveled and defect-removed, thereby improving the stability and flatness of the graphene fabric and the elastic film when they are bonded, the elastic film is leveled, and the glue is hot-melt treated so that the glue can be better and more evenly laid between the graphene fabric and the elastic film to improve the tightness of the fit between the graphene fabric and the elastic film. Since the glue is a hot-melt adhesive, when the elastic film and the graphene fabric are glued with a glue roller, the glue is evenly laid between the graphene fabric and the elastic film. In this way, in the subsequent drying process, no additional pressing process is required, and only natural drying and cooling are required, thereby reducing production costs.

[0012] In one embodiment of the present invention, in step S1, the graphene fabric includes graphene yarn and polyester yarn mixed in proportion, the graphene yarn and polyester yarn are hollow yarns, and the hollow ratio is 21% to 28%.

[0013] By implementing the above technical solution, graphene can protect against ultraviolet rays and has antibacterial effects, and the graphene yarn and polyester yarn are hollow yarns, which can make the fabric lightweight and have better thermal insulation effect. The combination of graphene can further improve the comfort of the fabric.

[0014] In one embodiment of the present invention, in step S1, the ratio of the graphene yarn to the polyester yarn is 4:6, and the graphene yarn is 50D hollow yarn.

[0015] To implement the above technical solution, since polyester yarn has good wear resistance, polyester yarn can improve the use strength of the fabric, and the graphene yarn of 50D hollow yarn can maintain good thermal insulation properties and lightweight characteristics, thereby improving the overall lightweight of the fabric and the high strength of the fabric to better adapt to the needs of various usage environments.

[0016] In one embodiment of the present invention, the graphene yarn and the polyester yarn are spun using a reverse wrapping process.

[0017] To implement the above technical solution, by weaving graphene yarn and polyester yarn using the reverse wrapping process, the durability of the fabric woven with the graphene yarn and polyester yarn can be improved, and the overall flatness and orderliness of the fabric can be improved, thereby improving the aesthetics of the fabric.

[0018] In one embodiment of the present invention, in step S2, the elastic film is a rubber elastic film, and the rubber elastic film is punctured with air-permeable micropores.

[0019] To implement the above technical solution, by adopting a rubber elastic membrane, the fabric has better resilience and is not easy to deform, so that the graphene fabric can maintain good synchronization with the rubber elastic membrane, and no cavitation will appear between the graphene fabric and the rubber elastic membrane, thereby ensuring that the graphene fabric and the rubber elastic membrane have good thermal insulation properties. By needle-piercing breathable micropores on the rubber elastic membrane, the overall breathability of the fabric can be improved to avoid the fabric being stuffy and airtight. The breathable micropores can make the fabric more breathable, thereby improving the use comfort of the fabric, making the fabric lighter and having a better thermal insulation effect.

[0020] In one embodiment of the present invention, the air-permeable micropores on the rubber elastic membrane are arranged in equal parts, and the aperture size of the air-permeable micropores on the side close to the human body is larger than the aperture size on the side close to the outside.

[0021] To implement the above technical solution, the breathable micropores on the rubber elastic membrane are arranged in equal parts, so that the breathability effect of each part of the fabric can be kept in a relatively uniform state, thereby ensuring the overall breathability of the fabric. Since the aperture size of the breathable micropores close to the human body is larger than the aperture size close to the outside world, under the action of the narrow tube effect, the airflow on the human body side can flow out smoothly, thereby ensuring the breathability of the fabric. Since the breathable micropores are needle-punctured holes, they also have the constant temperature characteristics required by the fabric, and it is difficult for the outside airflow to pass through the fabric. The breathable micropores designed in this way can maintain both breathability and good thermal insulation.

[0022] In one embodiment of the present invention, in step S4, the ambient temperature in the gluing working space is 20°C to 30°C, the humidity in the gluing working space is 50% to 70%, and the drying time of the elastic film and graphene fabric after gluing is controlled to be 11h to 12h.

[0023] To implement the above technical solution, the ambient temperature in the gluing workspace is set at 20°C to 30°C. During the hot melt adhesive application process, the hot melt adhesive can maintain good fluidity, so that the hot melt adhesive can be evenly spread between the elastic film and the graphene fabric. The humidity in the gluing workspace is maintained at 50% to 70%, which can prevent the hot melt adhesive from solidifying too quickly after gluing and failing to achieve a uniform laying effect. The drying time of the elastic film and graphene fabric after gluing is controlled to 11h to 12h. After the hot melt adhesive is spread, in order to maintain the bonding stability of the elastic film and the graphene fabric, natural drying is adopted. This can also avoid the problem of hot melt adhesive deformation caused by drying, which is more conducive to the overall flatness of the fabric.

[0024] In one embodiment of the present invention, in step S4, a glue groove with 1500 to 2400 points is set on the glue coating roller, the temperature of the glue coating roller is 80°C to 120°C, the glue coverage on the glue coating roller is 40% to 60%, the glue on the glue coating roller is hot melt glue, and the speed of the glue coating roller is controlled at 30m to 60m / min.

[0025] To implement the above technical solution, a glue groove with 1500 to 2400 points is set on the glue coating roller, and the glue coverage rate on the glue coating roller is 40% to 60%, so as to ensure the uniformity of the hot melt adhesive applied to the elastic film and the graphene fabric. The rotation speed of the glue coating roller is controlled at 30m to 60m / min, so that the hot melt adhesive in the glue groove has enough time to drip onto the glue coating surface of the fabric, and the glue can be evenly spread on the glue coating surface.

[0026] In one embodiment of the present invention, in step S5, the pressure of the pressing roller on the fabric is controlled to be 2kg to 5kg.

[0027] To implement the above technical solution, the pressure of the pressure roller on the fabric is controlled at 2kg to 5kg, which can ensure that the elastic film and the graphene fabric are pressed tightly, and that the glue between the elastic film and the graphene fabric can be evenly spread, thereby improving the bonding stability and reliability between the elastic film and the graphene fabric, while at the same time preventing the pressure of the pressure roller from being too high, which may cause the elastic film and the graphene fabric to be crushed.

[0028] As described above, the three-in-one graphene hydrophilic velvet fabric preparation process of the present invention has the following beneficial effects: by leveling and removing defects from the graphene fabric, the stability and flatness of the graphene fabric when bonding with the elastic film are improved, the elastic film is leveled, and the glue is hot-melt treated so that the glue can be better and more evenly laid between the graphene fabric and the elastic film, thereby improving the tightness of the fit between the graphene fabric and the elastic film.

[0029] By laminating the rubber elastic film between two pieces of graphene hydrophilic skin velvet fabrics, the skin-friendly properties of the graphene hydrophilic skin velvet fabric can be utilized. The graphene fabric is antibacterial and UV-resistant, thereby improving the comfort of the fabric. The rubber elastic film can improve the softness and elasticity of the fabric, making the fabric more comfortable to use. The rubber elastic film is a porous elastic film, which can make the fabric more breathable. The air holes can make the fabric have better heat insulation and warmth retention effects, thereby improving the comfort of the fabric, making the fabric lighter and having better thermal insulation effects.

[0030] Figure 1 Shown is a process flow chart of the three-in-one graphene hydrophilic skin velvet fabric preparation process disclosed in an embodiment of the present invention. DETAILED DESCRIPTION

[0031] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] See also Figure 1 The present invention provides a three-in-one graphene hydrophilic skin velvet fabric preparation process, comprising the following steps:

[0033] S1, pre-treated graphene fabric;

[0034] S2, pre-treatment elastic membrane;

[0035] S3, pre-treatment glue;

[0036] S4, applying glue to the elastic film and the graphene fabric with a glue coating roller, and applying glue to the contact surface between the elastic film and the graphene fabric;

[0037] S5. The elastic film and graphene fabric after glue coating are naturally dried in the workshop.

[0038] By leveling and removing defects from the graphene fabric, the stability and flatness of the graphene fabric and the elastic film when bonded are improved. The elastic film is leveled and the glue is hot-melt treated so that the glue can be better and evenly laid between the graphene fabric and the elastic film to improve the tightness of the fit between the graphene fabric and the elastic film. Since the glue is a hot-melt glue, when the elastic film and the graphene fabric are glued with a glue roller, the glue is evenly laid between the graphene fabric and the elastic film. In this way, in the subsequent drying process, no additional pressing process is required, and only natural drying and cooling are required, thereby reducing production costs.

[0039] In step S1, the graphene fabric includes graphene yarn and polyester yarn mixed in proportion, the graphene yarn and the polyester yarn are hollow yarns, and the hollow rate is 21% to 28%. Graphene can protect against ultraviolet rays and has antibacterial effects. The graphene yarn and the polyester yarn are hollow yarns, which can make the fabric lightweight and have better thermal insulation effect. The combination of graphene can further improve the comfort of the fabric.

[0040] In step S1, the ratio of graphene yarn to polyester yarn is 4:6, and the graphene yarn is 50D hollow yarn. Since polyester yarn has good wear resistance, polyester yarn can improve the strength of the fabric. The graphene yarn of 50D hollow yarn can maintain good thermal insulation properties and lightweight properties, thereby improving the overall lightweight of the fabric and the high strength of the fabric, so as to better adapt to the needs of various usage environments.

[0041] The graphene yarn and the polyester yarn are spun using the reverse wrapping process. By using the reverse wrapping process to weave the graphene yarn and the polyester yarn, the durability of the fabric woven with the graphene yarn and the polyester yarn can be improved, and the overall flatness and orderliness of the fabric can be improved, thereby improving the aesthetics of the fabric.

[0042] In step S2, the elastic membrane is a rubber elastic membrane, and breathable micropores are punctured on the rubber elastic membrane. By adopting the rubber elastic membrane, the resilience of the fabric is better and it is not easy to deform. In this way, the graphene fabric can maintain good synchronization with the rubber elastic membrane, and no cavitation will appear between the graphene fabric and the rubber elastic membrane, ensuring that the graphene fabric and the rubber elastic membrane have good thermal insulation properties. By puncturing breathable micropores on the rubber elastic membrane, the overall breathability of the fabric can be improved, and the fabric can be prevented from being stuffy and airtight. The breathable micropores can make the fabric more breathable, thereby improving the comfort of the fabric, making the fabric lighter and having a better thermal insulation effect.

[0043] The breathable micropores on the rubber elastic membrane are arranged in equal parts, and the aperture size of the breathable micropores on the side close to the human body is larger than the aperture size on the side close to the outside world. The breathable micropores on the rubber elastic membrane are arranged in equal parts, so that the breathability effect of each part of the fabric can be kept in a relatively uniform state, thereby ensuring the overall breathability of the fabric. Since the aperture size of the breathable micropores on the side close to the human body is larger than the aperture size on the side close to the outside world, under the action of the narrow tube effect, the airflow on the human body side can flow out smoothly, thereby ensuring the breathability of the fabric. Since the breathable micropores are needle-punctured holes, they also have the constant temperature characteristics required by the fabric, and it is difficult for the outside airflow to pass through the fabric. The breathable micropores designed in this way can maintain both breathability and good thermal insulation.

[0044] In step S4, the ambient temperature in the gluing workspace is 20° C. to 30° C., the humidity in the gluing workspace is 50% to 70%, and the drying time of the elastic film and graphene fabric after gluing is controlled to be 11 h to 12 h.

[0045] The ambient temperature in the gluing workspace is set at 20℃~30℃. During the hot melt adhesive application process, the hot melt adhesive can maintain good fluidity, so that the hot melt adhesive can be evenly spread between the elastic film and the graphene fabric. The humidity in the gluing workspace is kept at 50%~70%, which can prevent the hot melt adhesive from solidifying too quickly after gluing and failing to achieve the effect of uniform laying. The drying time of the elastic film and graphene fabric after gluing is controlled at 11h~12h. After the hot melt adhesive is spread, in order to maintain the bonding stability of the elastic film and the graphene fabric, natural drying is adopted. This can also avoid the problem of hot melt adhesive deformation caused by drying, which is more conducive to the overall flatness of the fabric.

[0046] In step S4, glue grooves with 1500 to 2400 points are set on the glue coating roller, the temperature of the glue coating roller is 80°C to 120°C, the glue coverage on the glue coating roller is 40% to 60%, the glue on the glue coating roller is hot melt glue, and the speed of the glue coating roller is controlled at 30m to 60m / min. By setting glue grooves with 1500 to 2400 points on the glue coating roller and the glue coverage on the glue coating roller is 40% to 60%, the uniformity of hot melt adhesive applied to the elastic film and the graphene fabric can be ensured, and the speed of the glue coating roller is controlled at 30m to 60m / min, so that the hot melt adhesive in the glue groove has enough time to drip onto the glue coating surface of the fabric, and the glue can be evenly spread on the glue coating surface.

[0047] In step S5, the pressure of the pressure roller on the fabric is controlled at 2kg-5kg. The pressure of the pressure roller on the fabric is controlled at 2kg-5kg, which can ensure that the elastic film and the graphene fabric are pressed tightly and the glue between the elastic film and the graphene fabric can be evenly spread, thereby improving the bonding stability and reliability between the elastic film and the graphene fabric. At the same time, the pressure of the pressure roller will not be too high, which will cause the elastic film and the graphene fabric to be crushed.

[0048] The present invention performs a flattening and defect removal treatment on the graphene fabric, thereby improving the stability and flatness of the graphene fabric and the elastic film when they are bonded, flattens the elastic film, and performs a hot-melt treatment on the glue, so that the glue can be better and more evenly laid between the graphene fabric and the elastic film, so as to improve the tightness of the fit between the graphene fabric and the elastic film, and by laminating the rubber elastic film between two graphene hydrophilic velvet fabrics, the skin-friendly properties of the graphene hydrophilic velvet fabric can be utilized, the graphene fabric can be antibacterial and anti-ultraviolet, and the comfort of the fabric can be improved, and the rubber elastic film can improve the softness and elasticity of the fabric, so that the fabric is more comfortable to use, and the rubber elastic film is a porous elastic film, which can make the fabric more breathable, and the air holes can make the fabric have better heat insulation and warmth-keeping effects, thereby improving the comfort of the fabric, making the fabric lighter, and having better heat preservation effects.
