Description

Technical Field

[0001] This utility model relates to the field of automotive interior materials technology, and in particular to automotive seat burr strips with antibacterial and anti-mildew functions. Background Technology

[0002] In the automotive interior design field, snap-on strips, as a quick-connect component, are widely used for the installation and removal of seat covers. Compared to traditional clips or stitching, snap-on strips enable convenient fixing of headrest covers, seat cushions, and seat frames, significantly improving the efficiency of cleaning and replacing seat covers, and substantially reducing user complexity and maintenance time costs.

[0003] Because car seat fenders are in direct contact with the human body for extended periods, they easily absorb sweat, dead skin cells, and other organic matter, creating a suitable environment for microbial growth. Studies have shown that harmful bacteria such as Staphylococcus aureus and Escherichia coli, as well as molds such as Aspergillus niger, readily multiply on the surface of the fenders. These microorganisms not only emit odors and accelerate the aging of the fenders, but may also threaten the health of drivers and passengers through contact. Furthermore, the commonly used nylon and polyester fender materials on the market lack antibacterial and anti-mold properties, failing to inhibit microbial growth at its source. The limitations of existing technology make the development of new car seat fenders that combine convenient installation with long-lasting antibacterial and anti-mold functions a pressing technical challenge. Utility Model Content

[0004] To overcome the technical defects of existing technologies, this utility model provides car seat burr strips with antibacterial and anti-mildew functions.

[0005] The technical solution adopted by this utility model is as follows: it includes a bristle strip body: the surface of the bristle strip body is provided with a material layer component and a functional component;

[0006] The material layer assembly includes microgrooves, a nano-titanium dioxide fiber layer, and functional components;

[0007] The microgrooves are formed at the edge of the bristle strip body, and the nano-titanium dioxide fiber layer and the modified polypropylene fiber layer are both disposed on the surface of the bristle strip body.

[0008] The modified polypropylene fiber layer includes micron-sized protrusions, pores, and nano-cerium oxide;

[0009] The micron-sized protrusions are disposed on one side of the bristle strip body, the holes are opened inside the bristle strip body, and the nano-cerium oxide is coated on the surface of the bristle strip body.

[0010] Preferably, the micron-sized protrusions are used to reduce liquid retention rate.

[0011] Preferably, the pores and the micron-sized protrusions are staggered, and the pores are used to release the antifungal agent in a slow-release manner.

[0012] Preferably, both the nano-titanium dioxide fiber layer and the modified polypropylene fiber layer are used to improve the antibacterial properties of the bristle strip body.

[0013] Preferably, the microgrooves are used to increase the specific surface area of the bristle strip body.

[0014] Preferably, the nano-cerium oxide is used to improve the mildew resistance of the bristle strip body.

[0015] The beneficial effects of this invention are as follows: By setting the material layer components, both the nano-titanium dioxide fiber layer and the modified polypropylene fiber layer can improve the antibacterial properties of the bristle strip body. The axial structure of the microgrooves matches the ergonomic curve of the seat, effectively increasing the specific surface area of the bristle strip body. By setting the functional components, the micron-level protrusions disrupt the microbial cell membrane, effectively reducing the liquid retention rate. The nano-cerium oxide degrades mycotoxins, thus improving the antifungal properties of the bristle strip body. The pores slowly release the antifungal agent. Therefore, through the above structure, the antibacterial and antifungal properties of the bristle strip body are effectively improved. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] As shown in the figure, this embodiment provides a car seat bristle strip with antibacterial and anti-mildew functions, including a bristle strip body 1: the surface of the bristle strip body 1 is provided with a material layer component 2 and a functional component 3;

[0023] The material layer component 2 includes microgrooves 201, nano-titanium dioxide fiber layer 202, and modified polypropylene fiber layer 203;

[0024] Microgrooves 201 are formed at the edge of the bristle strip body 1, and nano-titanium dioxide fiber layer 202 and modified polypropylene fiber layer 203 are both disposed on the surface of the bristle strip body 1.

[0025] Functional component 3 includes micron-sized protrusions 301, pores 302, and nano-cerium oxide 303;

[0026] Micron-sized protrusions 301 are disposed on one side of the bristle strip body 1, and holes 302 are formed inside the bristle strip body 1. Nano-cerium oxide 303 is coated on the surface of the bristle strip body 1. A nano-titanium dioxide fiber layer 202 and a modified polypropylene fiber layer 203 are disposed on the surface of the bristle strip body 1, so that both the nano-titanium dioxide fiber layer 202 and the modified polypropylene fiber layer 203 can improve the antibacterial properties of the bristle strip body 1. By forming microgrooves 201 at the edge of the bristle strip body 1, the groove axis of the microgrooves 201 is aligned with the ergonomic curve of the seat. The structure effectively increases the specific surface area of the bristle strip body 1; by setting a micron-sized protrusion 301 on one side of the bristle strip body 1, the micron-sized protrusion 301 destroys the cell membrane of microorganisms, effectively reducing the liquid retention rate; by coating the surface of the bristle strip body 1 with nano-cerium oxide 303, the nano-cerium oxide 303 degrades mycotoxins, thereby improving the anti-mold properties of the bristle strip body 1; by opening pores 302 inside the bristle strip body 1, the pores 302 slowly release the anti-mold agent. Thus, through the above structure, the antibacterial and anti-mold properties of the bristle strip body 1 are effectively improved.

[0027] Please see Figure 2 The micron-sized protrusions 301 are used to reduce the liquid retention rate. By setting the micron-sized protrusions 301 on one side of the bristle strip body 1, the micron-sized protrusions 301 destroy the microbial cell membrane and effectively reduce the liquid retention rate.

[0028] Please see Figure 2 The holes 302 and the micron-sized protrusions 301 are arranged alternately, and the holes 302 are used to release the anti-mildew agent. By opening the holes 302 inside the bristle strip body 1, the holes 302 release the anti-mildew agent in a slow manner.

[0029] Please see Figure 4 Both the nano-titanium dioxide fiber layer 202 and the modified polypropylene fiber layer 203 are used to improve the antibacterial properties of the bristle strip body 1. By setting the nano-titanium dioxide fiber layer 202 and the modified polypropylene fiber layer 203 on the surface of the bristle strip body 1, both the nano-titanium dioxide fiber layer 202 and the modified polypropylene fiber layer 203 can improve the antibacterial properties of the bristle strip body 1.

[0030] Please see Figure 2The microgrooves 201 are used to increase the specific surface area of the bristle strip body 1. By opening the microgrooves 201 at the edge of the bristle strip body 1, the axial direction of the grooves is matched with the ergonomic curve of the seat, effectively increasing the specific surface area of the bristle strip body 1.

[0031] Please see Figure 2 Nano-cerium oxide 303 is used to improve the anti-mildew properties of the bristle strip body 1. By coating the surface of the bristle strip body 1 with nano-cerium oxide 303, the nano-cerium oxide 303 degrades mycotoxins, thereby improving the anti-mildew properties of the bristle strip body 1.

[0032] Please see Figure 1 The micron-sized protrusion 301 has a triangular pyramidal structure, which effectively reduces the liquid retention rate.

[0033] The implementation principle of the car seat bristle strip with antibacterial and anti-mildew function in this application embodiment is as follows: First, a nano titanium dioxide fiber layer 202 and a modified polypropylene fiber layer 203 are set on the surface of the bristle strip body 1, so that both the nano titanium dioxide fiber layer 202 and the modified polypropylene fiber layer 203 can improve the antibacterial properties of the bristle strip body 1. By opening microgrooves 201 at the edge of the bristle strip body 1, the groove axis of the microgrooves 201 is matched with the ergonomic curve of the seat, effectively increasing the specific surface area of the bristle strip body 1.

[0034] By providing a micron-sized protrusion 301 on one side of the bristle strip body 1, the micron-sized protrusion 301 disrupts the microbial cell membrane, effectively reducing the liquid retention rate. By coating the surface of the bristle strip body 1 with nano-cerium oxide 303, the nano-cerium oxide 303 degrades mycotoxins, thereby improving the anti-mold properties of the bristle strip body 1. By opening pores 302 inside the bristle strip body 1, the pores 302 slowly release the anti-mold agent. Thus, through the above structure, the antibacterial and anti-mold properties of the bristle strip body 1 are effectively improved.
