Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fasteners, in particular to a waterproof and breathable hook and loop fastener. Background Art

[0002] Velcro is widely used, including on clothing. Velcro is generally used to tighten by bonding the main Velcro tape with the secondary Velcro tape.

[0003] At present, the existing Velcro on clothing will cause its breathability to decrease after being tightened. To solve this problem, Chinese patent No. CN212994899U discloses a breathable and waterproof Velcro. The device has good waterproof and breathable properties by using a first woven layer, a second woven layer, and a waterproof membrane layer as an intermediate layer. Since the waterproof membrane layer is located in the intermediate layer, the exterior of the Velcro can be waterproof when it is wet, but the exterior of the Velcro is wet, and there will be a lot of moisture in the woven layer, which will cause the woven layer to expand and squeeze the air holes inside it, thereby affecting the breathability of the Velcro. In view of this, a waterproof and breathable Velcro is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a waterproof and breathable hook and loop fastener that can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the waterproof and breathable Velcro proposed in the utility model includes a belt body, a Velcro mother tape is fixedly connected to the outer wall of the belt body, and a Velcro sub-tape is fixedly connected to the side of the belt body away from the Velcro mother tape. The belt body is composed of a base layer, an elastic layer, a protective layer, a waterproof layer and a waterproof membrane. The waterproof layer is composed of polyurethane and silicone polymer. The polyurethane fine porous layer coating method is a common waterproof finishing process. The polyurethane resin is dissolved in a solvent to make a coating liquid, which is then applied to the fabric and solidified in water to form a fine porous film, thereby achieving a waterproof function. The silicone polymer can form a hydrophobic layer to prevent water molecules from penetrating into the interior of the fabric. The waterproof membrane is synthesized by polyvinyl chloride and has a good waterproof effect.

[0006] Preferably, the base layer is fixed to the elastic layer, the side of the elastic layer away from the base layer is fixed to the protective layer, the side of the base layer away from the elastic layer is fixed to the waterproof layer, and the waterproof membrane is adhered to the side of the waterproof layer away from the base layer. Through the use of the protective layer and the elastic layer, the Velcro has good durability and softness, which improves the user's experience. At the same time, in the process of tightening the Velcro, the belt body can be stretched slightly to reduce damage to the belt body.

[0007] Preferably, the base layer, elastic layer and protective layer are all provided with air holes. The elastic layer is made of a combination of polyester and nylon and has durability and softness. The protective layer is woven from polyester and has greater friction on its surface.

[0008] Preferably, an air duct is provided in the waterproof layer, and the air duct is connected to the air holes. Through the use of the air duct and the air holes, the Velcro maintains good air permeability. When the belt body is affected by rainwater, the waterproof membrane and the protective layer can prevent rainwater from penetrating into the interior of the Velcro, thereby keeping the interior of the belt body in a dry state. The belt body will not swell due to absorbing a large amount of rainwater, thereby preventing the air holes from being squeezed and compressed, thereby ensuring the normal air permeability of the air holes.

[0009] Preferably, the end of the belt body away from the Velcro tape is rotatably connected to a buckle.

[0010] Preferably, the width of the main Velcro tape and the secondary Velcro tape are both smaller than the width of the tape body.

[0011] The utility model provides a waterproof and breathable hook and loop fastener with the following beneficial effects:

[0012] (1) The waterproof and breathable Velcro is not easily wetted by rain by placing the waterproof layer and the waterproof membrane on the outermost side, thereby keeping the tape body in a dry state. The tape body will not swell due to absorbing a large amount of rainwater, thereby preventing the air holes from being squeezed and compressed, ensuring the normal air permeability of the air holes and the air permeability effect of the Velcro.

[0013] (2) The waterproof and breathable Velcro has good durability and softness through the use of a protective layer and an elastic layer, which improves the user's experience. At the same time, during the process of tightening the Velcro, the belt body can be slightly stretched to reduce damage to the belt body. BRIEF DESCRIPTION OF THE DRAWINGS
