Description

Technical Field

[0001] This invention belongs to the field of mesh fabric technology, specifically relating to a production system for a stain-resistant, breathable, leather-like coated mesh fabric. Background Technology

[0002] Leather is currently classified into natural leather and synthetic leather. Natural leather is made from animal hides and is popular due to its advantages such as softness, breathability, wear resistance, high strength, and high moisture absorption. However, its high price limits its market appeal. Synthetic leather, on the other hand, is made by foaming or coating various formulations of PVC and PU onto woven or non-woven fabrics. Synthetic leather is widely used because it is not limited by raw materials and is easy to cut and process.

[0003] Materials used in footwear, apparel, bags, and automobiles typically prioritize a good texture and feel, often employing leather-like materials with natural grain and luster. However, synthetic leather materials have poor breathability, failing to meet the needs of scenarios requiring high breathability. Consequently, three-layer mesh, flyknit, and jacquard fabrics are sometimes used as alternatives. However, existing mesh fabrics lack the grain and waterproof properties of leather, making them prone to getting dirty and negatively impacting the customer's user experience.

[0004] With economic development and the continuous improvement of living standards, waterproof and breathable fabrics with waterproof and breathable properties are gradually entering people's lives. Publication number "CN203901831U" discloses a leather with a mesh layer, which is made by knitting a leather base layer with nylon yarn. The nylon yarn knitted leather base layer not only has the texture of a leather base layer, but also has multiple hollows in the leather base layer for breathability. However, the mesh fabric on both sides of the leather base layer is not resistant to dirt and is easily soiled. Publication number "CN208263570U" ​​discloses a waterproof and breathable fabric, which has at least one dry leather layer on a sandwich mesh fabric. The dry leather layer has multiple micropores. Since the dry leather layer on the surface of the sandwich mesh fabric has good dirt resistance, and the dry leather layer has micropores and the sandwich mesh fabric has good breathability, it is possible to prepare a stain-resistant and breathable leather-like coated mesh fabric that has both the breathability of mesh fabric and the dirt resistance of artificial leather by setting an artificial leather layer on the surface of the mesh fabric.

[0005] Among artificial leathers, polyurethane synthetic leather is the most widely used. There are two main types of production methods for polyurethane synthetic leather: dry and wet. Both methods involve dissolving liquid polyurethane resin granules in an organic solvent to form a slurry, and then using a coating machine to apply the slurry onto a substrate to form a wet coating. The former is dried by heating, while the latter is obtained by water replacement and solidification.

[0006] In existing technologies for preparing stain-resistant and breathable leather-like coated mesh fabric, molded polyurethane synthetic leather and mesh fabric are laminated together. The thickness of the molded polyurethane synthetic leather is fixed, but the required thickness of the polyurethane synthetic leather varies depending on the mesh fabric material. When laminating with the mesh fabric, if the polyurethane synthetic leather is too thick or too thin, it will affect the breathability and stain resistance of the stain-resistant and breathable leather-like coated mesh fabric. When preparing stain-resistant and breathable leather-like coated mesh fabric by directly laminating the coating liquid used to prepare polyurethane and synthetic leather with the mesh fabric, and then heating and drying, the thickness of the coating liquid can be adjusted, which solves the problem of the thickness requirement of polyurethane synthetic leather due to different mesh fabric materials in existing technologies. Publication number "CN202965422U" discloses a two-component polyurethane synthetic leather special coating machine, which coats the mesh fabric and release paper / release film with the coating liquid. However, because the coating liquid flows into the mesh holes between the mesh fabric, the poor breathability of the stain-resistant and breathable leather-like coated mesh fabric still occurs.

[0007] Based on the problems existing in the current technology, the applicant has devoted himself to the research and development of a production system for a stain-resistant and breathable leather-like coated mesh fabric, so that the resulting stain-resistant and breathable leather-like coated mesh fabric can solve the problems of poor breathability of leather and easy soiling of mesh fabric. Summary of the Invention

[0008] The purpose of this invention is to provide a production system for a stain-resistant and breathable leather-like coated mesh fabric, in order to solve the problems of poor breathability of leather and easy soiling of mesh fabric mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a production system for a stain-resistant and breathable leather-like coated mesh fabric, the production system comprising:

[0010] - Conveying mechanism 1, which is used to provide release paper / release film;

[0011] - Conveying mechanism two, which is used to provide release paper / release film;

[0012] - Coating and drying assembly one, which is connected to the conveying structure one, for coating and drying one side of the release paper / release film provided by the conveying mechanism one;

[0013] - Laminating roller assembly one, which is connected to coating and drying assembly one, is used to bond one side of the release paper / release film coated with resin coating to the preheated mesh, wherein the mesh and resin coating form a prefabricated anti-fouling and breathable leather-like coated mesh.

[0014] - Cooling wheel one, which is connected to the bonding roller group one, is used to cool the release paper / release film and the pre-made anti-fouling and breathable leather-like coated mesh after bonding by the bonding roller group one. The structures of cooling wheel one, cooling wheel two, and cooling wheel three include, but are not limited to, the following: cooling wheel one, cooling wheel two, and cooling wheel three each include, for example, a frame two and a roller one. A cooling component is installed inside the roller one. The support shafts installed at opposite ends of the roller one are connected to the frame two through bearing seats. The roller one can have more than one set. The side of the roller one is provided with an air outlet. The cooling component includes a cooling plate and a cooling system arranged in sequence. The cooling plate is in contact with the inner wall of the roller. The cooling plate includes multiple cooling units, and the cooler includes multiple cooling units arranged side by side on the multiple cooling units. The cooling units are arranged side by side on the radiator, and the radiator is fixedly connected to the roller. For example, the cooling plate is a high thermal conductivity aluminum substrate with model YZ-055 manufactured by Shenzhen Yizhuo Electronics Co., Ltd. For example, the cooler is a cooler with model FD-200W manufactured by Huizhou Fudi Electric Co., Ltd. For example, the radiator is a radiator manufactured by Foshan Nanhai Yixin Aluminum Products Co., Ltd.

[0015] - Laminating roller group two, which is connected between cooling wheel one and conveying mechanism two, is used to re-lax the pre-made anti-fouling and breathable leather-like coated mesh fabric, which has been cooled by cooling wheel one and peeled off release paper / release film, and the release paper / release film provided by conveying mechanism two. Both laminating roller group one and laminating roller group two include a first laminating roller, a second laminating roller, a rotating mechanism, a lifting mechanism, and a frame one. The first laminating roller is rotatably connected to the frame one, and the second laminating roller is slidably connected to the frame one, with the first laminating roller located above the second laminating roller. The rotating mechanism includes a first motor and a rotating shaft. The output end of the motor is fixedly connected to the rotating shaft, and the rotating shaft is axially fixedly connected to a first gear, with the rotating shaft and the first gear mutually transmitting power. A second gear is fixedly connected to one side of the first laminating roller, and the first laminating roller and the second... The two gears are interconnected and the first and second gears mesh together. The lifting mechanism includes a second motor, a lead screw, and a nut. The second motor is fixedly mounted on the frame. The lead screw is fixedly connected to the motor output end. The lead screw and the nut are threaded together. The second bonding roller group is fixedly connected to the side of the nut. When the lifting mechanism works, it drives the second bonding roller group to move up and down, thereby adjusting the distance between the first bonding roller and the second bonding roller. This facilitates the bonding of the resin-coated side of the release paper / release film with the preheated mesh or the re-bonding of the pre-made anti-fouling and breathable leather-like coated mesh and the release paper / release film provided by the second conveying mechanism. For example, the first motor, second motor, and third motor are selected from Taizhou Langbo Motor Co., Ltd., with the model number YE3-2.2KW-6P.

The prefabricated anti-fouling and breathable leather-like coated mesh is dried and cooled to obtain the anti-fouling and breathable leather-like coated mesh.

[0017] - Take-up roller assembly one, which is connected to the drying and cooling assembly, is used to take up the anti-fouling and breathable leather-like coated mesh fabric after it has been dried, cooled and shaped by the drying and cooling assembly and the release paper / release film has been peeled off. The take-up roller assembly one and the unwinding roller assembly have the same structure, and both the take-up roller assembly one and the unwinding roller assembly include a frame three, a third motor, a turntable, a roller two, a snap-fit ​​groove, and bolts. The third motor is fixedly installed on the upper side of the frame three. The output end of the third motor is fixedly connected to the turntable through a rotating shaft. The turntable has a snap-fit ​​groove for one end of the roller two to enter. Both the turntable and the roller two have threaded holes. After the roller two is snapped into the snap-fit ​​groove, the threaded holes of the turntable and the roller two are correspondingly set and fixed by bolts. After installation, the third motor works and drives the roller two to rotate, thereby taking up the anti-fouling and breathable leather-like coated mesh fabric after the release paper / release film has been peeled off or taking the release paper / release film.

The receiving table 92 conveys the release paper / release film to the unwinding roll assembly 91. The paper storage rack 93 continues to convey the release paper / release film conveyed by the receiving table 92 to the coating machine 11. After the coating machine 11 coats one side of the release paper / release film provided by the paper storage rack 93 with a resin coating, the first-stage drying oven 12 (at this time, the temperature of the first-stage drying oven 12 is set to 60°C) dries the release paper / release film coated with resin by the coating machine 11.

After that, it is conveyed to the second-stage oven 82 (set to 80℃) to dry the resin-coated release paper / release film applied by the second coating machine 81. The resin-coated release paper / release film dried in the second-stage oven 82 is then further dried. The release paper / release film is conveyed to the laminating roller group 2. The preheated mesh fabric, after being preheated by the preheating roller 10 (set to 80℃), is also conveyed to the laminating roller group 2. The resin-coated side of the release paper / release film is laminated with the preheated mesh fabric in the laminating roller group 2.

After lamination by the laminating roller group 2, the mesh fabric is conveyed to the cooling roller 3 (set to -5℃) to cool the laminated release paper / release film and anti-fouling, breathable, leather-like coated mesh fabric. The cooled release paper / release film... During the conveying process, the release paper / release film and the pre-made anti-fouling and breathable leather-like coated mesh are peeled off. The pre-made anti-fouling and breathable leather-like coated mesh after peeling off the release paper / release film is conveyed to the laminating roller group 2 4.

The receiving table 92 conveys the release paper / release film to the unwinding roller assembly 91. The paper storage rack 93 continues to convey the release paper / release film conveyed by the receiving table 92 to the coating machine 11. After the coating machine 11 coats one side of the release paper / release film provided by the paper storage rack 93 with a resin coating, the first-stage drying oven 12 (at this time, the temperature of the first-stage drying oven 12 is set to 60°C) dries the release paper / release film coated with resin by the coating machine 11.

[0120] After drying the resin-coated release paper / film in the first-stage oven 12, it is conveyed to the second cooling wheel 7. The second cooling wheel 7 (set to -10℃) cools it.

It is then conveyed to the second-stage oven 82 (set to 80℃) to dry the resin-coated release paper / film. The resin-coated release paper / film dried in the second-stage oven 82 is then conveyed to the first bonding roller group 2. The preheated mesh fabric, preheated by the preheating wheel 10 (set to 80℃), is also conveyed to the first bonding roller group 2. The first bonding roller group 2 bondes the resin-coated side of the release paper / film to the preheated mesh fabric.

[0124]

[0125] A comparison of the performance of stain-resistant and breathable leather-like coated mesh fabric A and H shows that the stain-resistant and breathable leather-like coated mesh fabric H, made by coating the release paper / release film and the mesh fabric with resin, only scored 3 points in the ballpoint pen ink stain test and only 4 points in the coffee stain test. Furthermore, its water vapor permeability was only 0.54 mg / cm³. 2 The method described in this application involves first coating the resin onto release paper / release film, then drying and cooling it before coating and drying again, and finally bonding it to the mesh fabric. This produces a stain-resistant and breathable leather-like coated mesh fabric that scores 0 points for both ballpoint pen ink stains and coffee stains, and its water vapor permeability is only 0.8 mg / cm³. 2 ·h; It can be seen that, under the same resin coating conditions, the antifouling and breathable leather-like coated mesh fabric produced by the antifouling and breathable coated mesh fabric production system of this application not only has a good antifouling effect, but also has good water vapor permeability.

[0126] A comparison of the performance of three stain-resistant and breathable leather-like coated mesh fabrics (A, F, and G) shows that, under the same production system, both fabrics (F and G) scored 3 points in the ballpoint pen ink stain test, but scored 3 points and 2 points respectively in the coffee stain test. Their water vapor permeability was also measured to be 0.68 mg / cm³. 2 ·h, 0.76mg / cm 2 The method described in this application involves first coating the resin onto release paper / release film, then drying and cooling it before coating and drying again, and finally bonding it to the mesh fabric. This produces a stain-resistant and breathable leather-like coated mesh fabric that scores 0 points for both ballpoint pen ink stains and coffee stains, and its water vapor permeability is only 0.8 mg / cm³. 2 ·h; It can be seen that, under the same production system for antifouling and breathable leather-like coated mesh, the antifouling and breathable leather-like coated mesh made using the resin coating of this application not only has a good antifouling effect, but also has good water vapor permeability.

[0127] The performance measured from stain-resistant and breathable leather-like coated mesh fabrics A to E shows that the stain-resistant and breathable leather-like coated mesh fabrics prepared using the resin coating of this application and the stain-resistant and breathable leather-like coated mesh fabric production system provided by this invention have excellent stain-resistant effects against both oily stains from ballpoint pens and liquid stains from coffee; and the water vapor permeability of the stain-resistant and breathable leather-like coated mesh fabric prepared by this invention can reach 0.78 mg / cm³. 2 With a pH above h, it has good water vapor permeability.

[0128] In summary, the anti-fouling and breathable leather-like coated mesh fabric production system and the anti-fouling and breathable leather-like coated mesh fabric prepared by the present invention not only have a good anti-fouling effect, but also have good water vapor permeability.
