Long-lasting dry and antibacterial polyester fabric and its preparation method

Abstract

This application discloses a long-lasting, dry, and antibacterial polyester fabric and its preparation method, relating to the field of polyester fabric technology. The application includes: a skin-adhesive layer, which is woven from ultra-fine polypropylene; and a first absorbent layer. This application employs an antibacterial mesh layer structure design to provide antibacterial properties to the polyester fabric, making it difficult for bacteria to grow in the skin-adhesive layer and the first absorbent layer. Subsequently, the dual absorbent structure design of the first and second absorbent layers allows for rapid wicking, diffusion, and transport of urine after it passes through the skin-adhesive layer due to capillary action generated by the micro-grooves on the surface of the shaped polyester yarns. This increases the speed at which urine passes through the skin-adhesive layer and allows it to quickly migrate to the interior of the second absorbent layer, achieving rapid moisture wicking and preventing urine that has passed through the skin-adhesive layer from re-contacting the skin. This results in long-lasting dryness for the polyester fabric, improving its functionality and user comfort.

Description

Technical Field

[0001] This application relates to the field of polyester fabric technology, specifically to long-lasting dry and antibacterial polyester fabric and its preparation method. Background Technology

[0002] As people's living standards improve, consumers have higher and higher requirements for the comfort and safety of sanitary products such as sanitary napkins and diapers. Polyester fabric is also widely used in the skin-adhesive layer of sanitary products. In order to provide users with a better user experience, it is necessary to improve the long-lasting dryness and antibacterial properties of polyester fabric.

[0003] During the processing and production of polyester fabric, its surface will be covered with a certain amount of lint. If this lint is not cleaned in time, it will hinder the subsequent processing of the polyester fabric. The existing technology uses an adhesion method to remove lint from the surface of polyester fabric. The lint removal effect of the adhesion device depends on its adhesiveness. After the adhesion device has been working for a period of time, its adhesiveness will be significantly reduced. Therefore, it is necessary to frequently clean the lint adhering to the outer surface of the adhesion device. In order to reasonably improve this problem, this application proposes a long-lasting dry and antibacterial polyester fabric and its preparation method. Summary of the Invention

[0004] The purpose of this application is to address the technical problem that in the prior art, the lint removal effect of the adhesive device depends on its adhesiveness when using an adhesive method to remove lint from the surface of polyester fabric. However, after the adhesive device has been working for a period of time, its adhesiveness will decrease significantly, thus requiring frequent cleaning of the lint adhering to the outer surface of the adhesive device. This application provides a long-lasting dry and antibacterial polyester fabric and its preparation method.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

Brushes are provided on the periphery of each cleaning roller, and multiple brushes are arranged linearly along the length of the cleaning roller and in multiple sets arranged in a ring along the axis of the cleaning roller.

[0015] Two cleaning components are provided, both of which are installed inside the cleaning box. The cleaning components are used to remove lint adhering to the brush.

[0016] A collection box is installed on the cleaning box. Collection pipes are installed on both sides of the collection box. The collection pipes pass through the cleaning box and have collection ports at their ends. The two collection ports face the two cleaning components respectively. A filter plate is installed inside the collection box. An exhaust pipe is constructed on the top of the collection box. A fan is installed inside the exhaust pipe.

[0017] A drive unit for driving one of the cleaning rollers to rotate;

[0018] To remove lint from the outer surface of polyester fabric using the above-mentioned lint removal device, the following steps are required:

[0019] S1: Feeding: The polyester cloth is passed through the inlet and outlet of the cleaning box and wound around the multiple rotating rollers one by one;

[0020] S2: Cleaning: When the drive unit is working, the cleaning roller rotates under the drive of the drive unit, so as to come into contact with the polyester fabric moving in the cleaning box, and the lint on the surface of the polyester fabric can be scraped off by the rotating brush.

[0021] S3: Cleaning: The cleaning component can separate the brush from the lint as the brush rotates;

[0022] S4: Collection: The lint removed by the cleaning component can be sucked into the collection box through the collection pipe, and the air and lint can be separated through the filter.

[0023] Furthermore, the transmission assembly includes a first spur gear constructed at the end of one of the cleaning rollers, a second spur gear rotatably mounted on the outside of the cleaning box and meshing with it, and the second spur gear being connected to the other cleaning roller via a pulley drive.

[0024] Furthermore, the cleaning assembly includes a fixed column fixedly installed inside the cleaning box. Each fixed column has a scraper on one side. The two scrapers are tangent to the rotation direction of the two cleaning rollers, and each scraper has a strip groove for the brush to pass through. Multiple strip grooves are linearly arranged along the length of the scraper.

[0025] Furthermore, there is a gap between the multiple sets of brushes.

[0026] Furthermore, the top of the scraper has an arc-shaped surface, the strip grooves all penetrate the bottom of the arc-shaped surface, and the collection port is located at the top of the strip grooves.

[0027] Furthermore, a plurality of intercepting rods are fixedly connected to one side of the collection box, both collection pipes are installed at the bottom of the collection box, and the filter plate is disposed at the top of the collection box.

[0028] Furthermore, the spacing between the plurality of intercepting bars gradually increases from the top of the collection box toward its bottom.

[0029] Furthermore, a cleaning port is provided on one side of the collection box, and multiple intercepting bars are installed on the side of the collection box opposite to the cleaning port. The cleaning port is equipped with a box door, the outer side of the box door has a handle, the inner side of the box door has a connecting post, a cleaning plate is slidably fitted inside the collection box, the cleaning plate is connected to the connecting post, and multiple intercepting bars pass through the cleaning plate.

[0030] Furthermore, a limiting groove is constructed inside the collection box, and a limiting block is constructed on the cleaning plate, with the limiting block slidingly engaging with the limiting groove.

[0031] The beneficial effects of this application are as follows:

[0032] 1. This application employs an antibacterial mesh layer structure design to provide antibacterial properties to the polyester fabric, making it difficult for bacteria to grow in the skin-adhesive layer and the first absorbent layer. Subsequently, the dual absorbent structure design of the first and second absorbent layers allows the capillary effect generated by the micro-grooves on the surface of the shaped polyester filaments to enable urine to be quickly wicked, diffused, and transported after passing through the skin-adhesive layer, thereby increasing the speed at which urine passes through the skin-adhesive layer and enabling it to quickly migrate into the interior of the second absorbent layer to achieve the purpose of rapid moisture wicking. Furthermore, with the cooperation of the skin-adhesive layers, the speed at which urine passes through the skin-adhesive layer can be accelerated, and the urine that has passed through the skin-adhesive layer is less likely to come into contact with the skin again, thereby improving the long-lasting dryness performance of the polyester fabric.

[0033] 2. This application employs a design combining a cleaning roller and a brush. During operation, the rotating brush removes lint from the top and bottom of the polyester fabric. The cleaning component's structural design separates the lint from the brush, ensuring the brush's cleaning effect is not significantly affected by the lint. The lint is then drawn into a collection box through a collection port, preventing it from re-adhering to the polyester fabric. Compared to existing adhesion devices, this design quickly and effectively removes lint from polyester fabric, and the cleaning effect remains unaffected even after prolonged use, eliminating the need for frequent cleaning by staff, representing a significant improvement.

[0034] 3. This application employs a transmission component design. When the drive unit is working, the cleaning roller can be rotated by the meshing first helical gear and second helical gear, and the second spur gear can be rotated by the first spur gear, thereby driving the other cleaning roller to rotate relative to it via the pulley. It should be specifically noted that the two cleaning rollers are located at the top and bottom of the polyester fabric, respectively. When the two rotate relative to each other, their rotation direction is opposite to the movement direction of the polyester fabric, so that the brush can better pick up the lint on its surface.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0045] like Figures 1-2 As shown, one embodiment of this application proposes a long-lasting dry and antibacterial polyester fabric, comprising:

[0046] Skin-adhesive layer 1 is made of ultra-fine polypropylene. Ultra-fine polypropylene has both water-repellent and natural wicking properties. Therefore, this process can generally be used to create a one-way moisture-wicking effect so that urine passing through skin-adhesive layer 1 will not come into contact with the skin again.

[0047] The first absorbent layer 2 is connected to the inner surface of the skin-adhesive layer 1. The first absorbent layer 2 is woven from shaped polyester yarns 201 and spandex yarns 202. The shaped polyester yarns 201 are cross-shaped, and multiple spandex yarns 202 are wound around the periphery of the shaped polyester yarns 201. The capillary effect generated by the micro-grooves on the surface of the shaped polyester yarns 201 and the spandex yarns 202 allows urine to be quickly wicked, diffused, and transported after passing through the skin-adhesive layer 1. This increases the speed at which urine passes through the skin-adhesive layer 1, allowing the urine to quickly migrate into the interior of the first absorbent layer 2 and disperse, thereby achieving the purpose of rapid moisture wicking.

[0048] An antibacterial mesh layer 3 is disposed between the skin-adhering layer 1 and the first absorbent layer 2. The antibacterial mesh layer 3 includes polyester short fiber yarns, and bamboo charcoal fiber and silver ion fiber are wound around the outside of the polyester short fiber yarns. The silver ion fiber is a nano-silver fiber. When urine passes through the skin-adhering layer 1 and comes into contact with the antibacterial mesh layer 3, the biological activity of silver ions on the nano-silver fiber will be enhanced due to the influence of urine temperature, thereby effectively inhibiting the growth of bacteria in the skin-adhering layer 1 and the first absorbent layer 2. Bamboo charcoal fiber has multiple characteristics such as moisture absorption and breathability, as well as antibacterial properties. The antibacterial effect is better after the silver ion fiber and bamboo charcoal fiber are blended.

[0049] The second absorbent layer 4 is made of absorbent cotton. The absorbent cotton has a good water absorption effect. After urine enters the first absorbent layer 2 and diffuses, it can be quickly transferred to the second absorbent layer 4. Through the double absorption of the first absorbent layer 2 and the second absorbent layer 4, urine can be absorbed quickly and effectively. Under the one-way moisture-wicking performance of the skin-adhesive layer 1, urine passing through the skin-adhesive layer 1 is less likely to come into contact with the skin again, thus keeping the polyester fabric dry for a long time.

[0050] This application employs an antibacterial mesh layer 3 to provide antibacterial properties to the polyester fabric, making it less prone to bacterial growth in the skin-adhesive layer 1 and the first absorbent layer 2. Subsequently, the dual absorbent structure of the first absorbent layer 2 and the second absorbent layer 4 allows for rapid wicking, diffusion, and transport of urine after it passes through the skin-adhesive layer 1, thanks to the capillary effect generated by the micro-grooves on the surface of the shaped polyester filaments 201. This increases the speed at which urine passes through the skin-adhesive layer 1 and allows it to quickly migrate into the second absorbent layer 4, achieving rapid moisture wicking. Furthermore, the cooperation of the skin-adhesive layer 1 accelerates the speed at which urine passes through it and prevents urine that has passed through the skin-adhesive layer 1 from re-contacting the skin, thereby improving the long-lasting dryness performance of the polyester fabric.

[0051] like Figures 3-8 As shown in one embodiment of this application, a method for preparing long-lasting dry and antibacterial polyester fabric is provided, which uses a lint removal device, comprising:

[0052] The cleaning box 5 has an inlet and an outlet on each side for the polyester fabric to enter and exit.

[0053] The material conveying mechanism includes multiple rotating rollers 6 that are rotatably engaged with the cleaning box 5. The multiple rotating rollers 6 are connected to each other through a transmission mechanism and are connected by a roller belt.

[0054] There are two cleaning mechanisms 7, which are symmetrically arranged on both sides of the polyester fabric with the vertical offset. Specifically, the vertical offset means that the cleaning mechanisms 7 are centrally symmetrical with the middle of the polyester fabric as the center. The two cleaning mechanisms 7 clean the lint on the top and bottom of the polyester fabric respectively. The cleaning mechanism 7 includes a cleaning roller 8 rotatably installed in the cleaning box 5. The two cleaning rollers 8 are connected by a transmission component 9. When one cleaning roller 8 rotates, the other cleaning roller 8 also rotates. The axis of the cleaning roller 8 is parallel to the rotating roller 6. Brushes 10 are arranged around the periphery of the cleaning roller 8. Multiple brushes 10 are arranged linearly along the length of the cleaning roller 8 and multiple sets are arranged in a ring along the axis of the cleaning roller 8. When the cleaning roller 8 rotates, the brushes 10 can scrape off the lint on both sides of the polyester fabric.

[0055] There are two cleaning components 11, both of which are installed in the cleaning box 5. The cleaning components 11 are used to remove lint adhering to the brush 10. When the cleaning roller 8 rotates, the cleaning components 11 can separate the brush 10 from the lint scraped off, thereby improving the cleaning effect of the brush 10.

[0056] A collection box 12 is installed on the cleaning box 5. Collection pipes 13 are installed on both sides of the collection box 12. The collection pipes 13 pass through the cleaning box 5 and each end of the collection box 12 is provided with a collection port 14. The two collection ports 14 are respectively facing the two cleaning components 11. A filter plate 15 is provided inside the collection box 12. An exhaust pipe 16 is constructed on the top of the collection box 12. A fan 17 is installed in the exhaust pipe 16. When the fan 17 rotates, the gas in the collection box 12 is discharged and the two collection ports 14 are sucked in, so that the lint separated by the cleaning components 11 can be sucked into the collection box 12 and the air is separated from the lint by the filter plate 15 to complete the collection of lint.

[0057] The driving component 18 is specifically a motor, which is used to drive one of the cleaning rollers 8 to rotate. A first helical gear 19 is installed on the output shaft of the driving component 18, and a second helical gear 20 that meshes with the first helical gear 19 is connected to the end of one of the cleaning rollers 8. When the driving component 18 is working, it can drive both cleaning rollers 8 to rotate.

[0058] To remove lint from the outer surface of polyester fabric using the above-mentioned lint removal device, the following steps are required:

[0059] S1: Feeding: Pass the polyester cloth through the inlet and outlet of the cleaning box 5 and wrap it around multiple rotating rollers 6 one by one;

[0060] S2: Cleaning: When the drive unit 18 is working, the cleaning roller 8 rotates under the drive of the drive unit 18, so that it can come into contact with the polyester fabric moving in the cleaning box 5, and the lint on the surface of the polyester fabric can be scraped off by the rotating brush 10.

[0061] S3: Cleaning: The cleaning component 11 can separate the brush 10 from the lint while the brush 10 is rotating;

[0062] S4: Collection: The lint removed by the cleaning component 11 can be sucked into the collection box 12 through the collection pipe 13, and the air and lint can be separated through the filter.

[0063] This application employs a design with a cleaning roller 8 and a brush 10. When the drive unit 18 is working, the rotating brush 10 can remove lint from the top and bottom of the polyester fabric. Subsequently, through the structural design of the cleaning component 11, the lint can be separated from the brush 10, thus ensuring that the cleaning effect of the brush 10 is not easily affected by the lint. Then, the lint can be sucked into the collection box 12 through the collection port 14, so that the lint is not easily re-adhered to the polyester fabric. Compared with existing adhesion devices, this design can quickly and effectively remove lint from the polyester fabric, and the lint removal effect is not easily affected by long-term use, eliminating the need for frequent cleaning by staff, which is a significant improvement.

[0064] like Figure 4 and Figure 5 As shown, in some embodiments, the transmission assembly 9 includes a first spur gear 21 constructed at the end of one of the cleaning rollers 8, specifically the cleaning roller 8 that is connected to the drive member 18. A second helical gear 20 is fixedly connected to the top of the first spur gear 21. A second spur gear 22 is rotatably mounted on the outside of the cleaning box 5 and meshes with it. The second spur gear 22 is connected to the other cleaning roller 8 via a pulley 23. When the drive member 18 is working, the cleaning roller 8 can be driven to rotate by the meshing first helical gear 19 and second helical gear 20, and the second spur gear 22 can be driven to rotate by the first spur gear 21, thereby driving the other cleaning roller 8 to rotate relative to it via the pulley 23. It should be specifically noted that the two cleaning rollers 8 are located at the top and bottom of the polyester fabric, respectively. When the two rotate relative to each other, their rotation direction is opposite to the movement direction of the polyester fabric, so that the brush 10 can better pick up the lint on its surface.

[0065] like Figure 6 and Figure 7As shown, in some embodiments, the cleaning component 11 includes a fixed column 24 fixedly installed in the cleaning box 5. The fixed column 24 is set on the side of the cleaning roller 8 located in the forward direction of the polyester fabric. A scraper 25 is constructed on one side of the fixed column 24. The two scrapers 25 are tangent to the rotation direction of the two cleaning rollers 8, and each has a strip groove 26 for the brush 10 to pass through. Multiple strip grooves 26 are linearly arranged along the length of the scraper 25. After the brush 10 cleans the lint off the surface of the polyester fabric on the cleaning roller 8, it continues to rotate. At this time, the brush 10 can pass through the strip groove 26 of the scraper 25 and intercept the lint hanging on the brush 10 on the scraper 25 through the groove opening of the strip groove 26, so as to complete the separation of the brush 10 and the lint, so that the collection port 14 can suck it in.

[0066] like Figure 6 and Figure 7 As shown, in some embodiments, there is a gap between the multiple sets of brushes 10. With this design, by increasing the gap between the individual sets of brushes 10, more lint can be hung on the individual set of brushes 10 during cleaning, making it easier to separate the brushes 10 from the lint through the strip groove 26.

[0067] like Figure 6 and Figure 7 As shown, in some embodiments, the top of the scraper 25 is constructed with an arc-shaped surface 27, which is opposite to the rotation direction of the cleaning roller 8. The strip grooves 26 all penetrate the bottom of the arc-shaped surface 27, and the collection port 14 is located at the top of the strip grooves 26. When the brush 10 passes through the strip grooves 26 of the scraper 25, the lint hanging on the brush 10 can be intercepted on the scraper 25 and accumulate on the bottom of the arc-shaped surface 27, so that even when the cleaning roller 8 rotates too fast, the lint is less likely to stick and detach from the scraper 25, so that the collection port 14 can suck in the cleaned lint.

[0068] like Figure 8 As shown, in some embodiments, a plurality of intercepting rods 28 are fixedly connected to one side of the collection box 12, and two collection pipes 13 are installed at the bottom of the collection box 12. The filter plate 15 is set at the top of the collection box 12. Because the lint is light, it is easy to adhere to the filter plate 15 under the action of the air flowing in the collection box 12 and quickly block the filter plate 15, affecting the collection effect of the collection port 14. The design of the intercepting rods 28 can intercept the lint, so that it is not easy for it to adhere to the filter plate 15 under the action of the air, so that the filter plate 15 is not easy to be blocked.

[0069] like Figure 8 As shown, in some embodiments, the spacing between the multiple interception bars 28 gradually increases from the top of the collection box 12 toward its bottom. This design allows for layered interception of lint of different adhering volumes, resulting in a better lint interception effect.

[0070] like Figure 8 As shown, in some embodiments, a cleaning port 29 is provided on one side of the collection box 12. Multiple intercepting rods 28 are installed on the side of the collection box 12 opposite to the cleaning port 29. The cleaning port 29 is equipped with a door 30, which is installed on one side of the collection box 12 by a latch. The outer side of the door 30 has a handle 31, and the inner side of the door 30 has a connecting post 32. A cleaning plate 33 is slidably fitted inside the collection box 12. The cleaning plate 33 is connected to the connecting post 32, and multiple intercepting rods 28 pass through the cleaning plate 33. The length of the intercepting rod 28 is equal to the distance from the side of the cleaning plate 33 away from the door 30 to the door 30. When it is necessary to clean the lint in the collection box 12, the door 30 can be pulled out horizontally by pulling the handle 31. Under the action of the connecting post 32, the cleaning plate 33 moves toward the cleaning port 29, thereby driving the lint intercepted by the intercepting rod to move toward the cleaning port 29 for cleaning.

[0071] like Figure 8 As shown, in some embodiments, a limiting groove 34 is constructed inside the collection box 12, and a limiting block 35 is constructed on the cleaning plate 33. The limiting block 35 and the limiting groove 34 slide together. Through the design of the cooperation between the limiting block 35 and the limiting groove 34, the maximum moving distance of the cleaning plate 33 can be limited so that the cleaning plate 33 is not easy to detach from the intercepting post when sliding.

[0072] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
