Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fasteners, in particular to an anti-static hook and loop fastener. Background Art

[0002] Velcro, also known as hook and loop fastener, is a common quick-connect material. Due to the physical properties of Velcro, including heat resistance, cold resistance and the influence of humidity on its performance, for example, the melting point of the hook surface is about 230°C, while the velvet surface begins to soften at 180°C. When the humidity is high, the tensile force of the Velcro will decrease, but it can be restored after drying. Therefore, Velcro is widely used in clothing, shoes and hats, luggage, furniture, medical equipment and other fields.

[0003] Common Velcro consists of two parts: one side with tiny hooks and the other side with loops or fluff. The two parts can adsorb to each other, providing convenient connection and release functions. However, this method easily generates static electricity due to the friction between the Velcro when adsorbed and pulled, which poses a great safety hazard when used in some occasions and cannot meet the working requirements of Velcro. For this reason, an anti-static Velcro is proposed. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the present invention provides an anti-static Velcro to solve the technical problem that static electricity is easily generated when the Velcro rubs against each other during adsorption and pulling, thus posing a great safety hazard when used in some occasions.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an anti-static hook and loop fastener, comprising:

[0008] A fine hook layer, wherein an upper moisturizing layer is laid on the bottom of the fine hook layer, an oil storage layer is laid on the lower part of the upper moisturizing layer, and a lower moisturizing layer is laid on the bottom of the oil storage layer;

[0009] The fleece layer is laid on the bottom of the lower moisturizing layer. The outer portions of the fine hook layer, the upper moisturizing layer, the oil storage layer, the lower moisturizing layer and the fleece layer are all covered with an annular cloth belt.

[0010] Preferably, the fine hook layer, upper moisturizing layer, oil storage layer, lower moisturizing layer and fleece layer are bonded together by adhesive, and edge sealing lines are sewn on the left and right sides of the fine hook layer, upper moisturizing layer, oil storage layer, lower moisturizing layer and fleece layer, and the added edge sealing lines improve the strength of the Velcro.

[0011] Preferably, penetration holes are provided inside the fine hook layer and the fleece layer, and the penetration holes are of a through structure. Spherical bumps are installed on the upper and lower sides of the oil storage layer. The added spherical bumps can prevent the loss of oil, extend the duration of oil, and reduce the dynamic and static friction coefficient for a longer period of time.

[0012] Preferably, conductive strips are inserted into the upper and lower sides of the annular cloth belt, and the conductive strips are made of nickel foil, which can effectively conduct electric charges and reduce the generation and accumulation of static electricity.

[0013] Preferably, the oil storage layer is woven from polypropylene fibers, which improves water absorption, and the upper moisturizing layer and the lower moisturizing layer are both made of highly absorbent resin materials, which improves moisturizing performance.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides an anti-static hook and loop fastener with the following beneficial effects:

[0016] 1. The anti-static hook and loop fastener can effectively retain the oil in the fine hook layer and the fleece layer through the added oil storage layer, so that the relatively abundant oil can reduce the dynamic and static friction coefficient, thereby reducing the possibility of static electricity generation. At the same time, the added upper and lower moisturizing layers can effectively increase the humidity between the layers. Increasing the humidity can increase the dielectric constant of the anti-static layer, avoiding the generation of static electricity due to insufficient humidity. The provision of the moisturizing layer can ensure that the anti-static hook and loop fastener can maintain good anti-static performance even in a dry environment, avoiding the phenomenon of static electricity during use of the hook and loop fastener. This makes the hook and loop fastener safer in flammable and explosive environments or in firefighting clothing, electrician clothing, laboratories and other occasions requiring anti-static protection.

[0017] 2. The anti-static Velcro can leave gaps after adsorption due to the added annular cloth tape, and the annular cloth tape can relatively reduce the contact area between the fine hook layer and the fleece layer. On the one hand, leaving gaps is conducive to air circulation, which can promote the rapid release of static electricity, and the air flow can accelerate the dissipation of charges and reduce the possibility of static electricity accumulation. At the same time, reducing the contact area between the fine hook layer and the fleece layer avoids the problem of the Velcro being too tightly adsorbed and difficult to separate, making it convenient to tear the Velcro.
