Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fasteners, in particular to a stain-resistant and oil-repellent hook and loop fastener. Background Art

[0002] Velcro is a common connecting material, usually composed of two parts: one side is a soft fiber surface, and the other side is a hard surface with tiny hooks. When the two sides are fit together, the hooks will hook the fibers, thus achieving connection. Velcro has the advantages of convenience, speed and reusability. It is widely used in clothing, shoes, luggage, household items and other fields. It can replace traditional buttons, zippers and other connection methods, providing a more convenient use experience. During use, it will be exposed to various stains and greases, and these stains and greases will adhere to it, which will not only affect the appearance, but may also reduce its viscosity and service life, so it must be stain-resistant and oil-repellent.

[0003] Existing stain-resistant and oil-repellent Velcro usually has an oil-resistant and water-repellent surface on its surface, which can effectively prevent stains and grease from adhering to the surface of the Velcro, keeping it clean and having good performance. The treatment of the oil-resistant and water-repellent surface can be achieved in a variety of ways, such as using special coatings or adding materials with oil-resistant and water-repellent properties. Such treatment enables the Velcro to better resist the erosion of various stains and grease, reduce the residual stains, and thus extend the service life of the Velcro.

[0004] However, existing stain-resistant and oil-repellent Velcro tapes typically rely solely on their surface oil and water repellency to resist adhesion. Although this surface treatment can prevent the adhesion of stains and grease to a certain extent, a small amount of oil stains may still enter the interior of the Velcro tape. The lack of internal drainage holes for the oil stains causes the oil stains to accumulate inside, which may have a negative impact on the performance and service life of the Velcro tape. Therefore, stain-resistant and oil-repellent Velcro tapes are proposed to solve this problem. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a stain-resistant and oil-repellent Velcro, aiming to improve the problem in the prior art that a small amount of oil stains still enter and accumulate inside, resulting in a decrease in its performance.

[0006] To achieve the above-mentioned purpose, the embodiment of the present invention provides a stain-resistant and oil-repellent hook and loop fastener, comprising a hook and loop fastener body, a bevel provided on the top of the hook and loop fastener body, a hook angle fixedly connected to the top of the bevel, an oil drainage groove provided inside the bevel, an isolation layer fixedly connected to the bottom of the bevel, an oil guide layer fixedly connected to the bottom of the isolation layer, an adhesive layer fixedly connected to the bottom of the oil guide layer, an oil absorption layer fixedly connected to the bottom of the adhesive layer, a closing component provided on the outer wall of the hook and loop fastener body, the closing component acting to close the hook and loop fastener body;

[0007] Optionally, the closing component includes an edge seal, and the outer wall of the edge seal is fixedly connected to the outer wall of the hook and loop fastener body;

[0008] Optionally, an oil guide groove is provided inside the oil guide layer, and an oil leakage hole is provided inside the oil guide layer;

[0009] Optionally, an adhesive layer is fixedly connected to the bottom of the oil-conducting layer, and transverse fibers, weft fibers and longitudinal fibers are arranged inside the adhesive layer;

[0010] Optionally, the transverse fibers and the longitudinal fibers are arranged in a staggered manner and fixedly connected between the oil-conducting layer and the oil-absorbing layer;

[0011] Optionally, the inclined surface is made of a hydrophobic material;

[0012] Optionally, the oil absorption layer is made of a polymer material.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, the coordination among the inclined surface, the oil guide groove, the oil leakage hole and the oil absorption layer can achieve the goal of preventing oil on the surface of the Velcro and absorbing and discharging the oil stains that enter the interior, thereby solving the problem that only a small amount of oil stains can still enter the interior and cause internal contamination after surface oil protection is performed, thereby improving the service life.

[0025] Reference Figure 1-Figure 3, the stain-resistant and oil-repellent Velcro includes a Velcro body 1, a slope 5 is provided on the top of the Velcro body 1, a hook angle 3 is fixedly connected to the top of the slope 5, an oil drainage groove 2 is opened inside the slope 5, an isolation layer 8 is fixedly connected to the bottom of the slope 5, an oil guide layer 13 is fixedly connected to the bottom of the isolation layer 8, an adhesive layer 10 is fixedly connected to the bottom of the oil guide layer 13, and an oil absorption layer 6 is fixedly connected to the bottom of the adhesive layer 10. The outer wall of the Velcro body 1 is provided with a closing component, which acts to close the Velcro body 1. The component includes a sealing edge 4, the outer wall of the sealing edge 4 is fixedly connected to the outer wall of the Velcro body 1, an oil guide groove 7 is opened inside the oil guide layer 13, an oil leakage hole 9 is opened inside the oil guide layer 13, and an adhesion layer 10 is fixedly connected to the bottom of the oil guide layer 13. Transverse fibers 11 and weft fibers and longitudinal fibers 12 are arranged inside the adhesion layer 10. The transverse fibers 11 and the longitudinal fibers 12 are staggered and fixedly connected between the oil guide layer 13 and the oil absorption layer 6. The inclined surface 5 is made of hydrophobic material, and the oil absorption layer 6 is made of polymer material.

[0026] Specifically, the isolation layer 8 is precisely located at the top of the Velcro body 1, and its main function is to isolate the oil stains dripping from the outside, wherein the top of the isolation layer 8 is set as a slope 5, which can effectively promote the oil stains to slide down, and at the same time, the oil drain groove 2 is specially opened at the non-contact part of the slope 5 and the hook angle 3. This design can better drain the oil stains. Even if a small amount of oil stains break through the defense line and enter the interior of the Velcro body 1, they will first be discharged through the oil guide groove 7 on the surface of the oil guide layer 13 in the middle, and those oil stains that cannot be discharged from the oil guide groove 7 will be discharged. Oil stains will enter the interior of the oil absorption layer 6 through the oil conducting layer 13. Since the oil absorption layer 6 is carefully made of polymer material, it has the ability to efficiently absorb the oil stains and eventually discharge them. The oil conducting layer 13 and the oil absorption layer 6 are tightly adhered by the adhesive layer 10, and the transverse fibers 11 and the longitudinal fibers 12 are interlaced inside. Such a structure can effectively prevent it from being separated or damaged due to tension or pressure during use. At the same time, its internal gap is large, which can effectively allow the oil stains to penetrate smoothly and be absorbed by the oil absorption layer 6.

[0027] Working principle: When oil stains or sewage drip onto the surface of the Velcro body 1, they first slide down through the inclined surface 5 set on the top isolation layer 8, and at the same time, the oil stains on the side of the hook corner 3 are discharged through the oil drainage groove 2 set on the isolation layer 8. The oil that slips through the net enters the interior of the Velcro body 1 through the gap and enters the surface of the oil guide layer 13. The oil stains are first guided and discharged through the oil guide groove 7 opened on its surface. The oil stains that have not been discharged can slide into the interior of the adhesive layer 10 through the oil leakage hole 9 opened in the oil guide layer 13, and then flow into the surface of the oil absorption layer 6 through the adhesive layer 10, and be absorbed and discharged by its material.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
