Description

Technical Field

[0001] The utility model relates to the technical field of yarns, and more specifically to an antistatic yarn. Background Art

[0002] Anti-static yarn is a yarn that is specially treated or made from specific materials and is designed to prevent or reduce the accumulation of static electricity;

[0003] The existing antistatic yarn {such as the publication (announcement) number: CN209194119U, a high-performance conductive yarn} states: "The carbon nanotube base line can be immersed in a silver nanowire dispersion, and then heated and dried to make the silver nanowire contaminate the surface of the carbon nanotube base line or fill the three-dimensional network structure inside the carbon nanotube base line, thereby realizing the composite of the carbon nanotube base line and the silver nanowire";

[0004] Furthermore, the above-mentioned “high-performance conductive yarn” states: “the carbon nanotube baseline is passed through a 5% polyvinyl alcohol solution, and then dried at 140-160°C to form a uniform polyvinyl alcohol coating on the surface of the carbon nanotube baseline”, that is, a silver nanowire dispersion layer and a polyvinyl alcohol coating are sequentially arranged directly outside the carbon nanotube baseline, which has the disadvantages of low conductive stability and protection of the nanowire dispersion layer; at the same time, the use of the polyvinyl alcohol coating as a protective layer has the disadvantages of insufficient weather resistance, mechanical strength, chemical resistance, wear resistance and corrosion resistance. Utility Model Content

[0005] The purpose of the utility model is to provide an antistatic yarn in order to solve the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model provides an antistatic yarn, comprising a yarn body, a conductive layer arranged outside the yarn body, and a wear-resistant layer fixed outside the conductive layer, and also comprising a shaping layer fixed between the yarn body and the conductive layer, wherein the shaping layer is a soft shaping layer.

[0008] As a preferred technical solution of the utility model, the wear-resistant layer is the same as the shaping layer.

[0009] As a preferred technical solution of the utility model, the wear-resistant layer and the shaping layer are both coating layers.

[0010] As a preferred technical solution of the utility model, the wear-resistant layer and the shaping layer are both polyurethane coating layers, acrylic coating layers or silicone resin coating layers.

[0011] As a preferred technical solution of the utility model, the conductive layer is a copper nanowire coating.

[0012] The beneficial effects of the utility model are as follows:

[0013] By sequentially arranging a shaping layer, a conductive layer and a wear-resistant layer on the outer side of the wire body, the conductive layer is subjected to a sandwich shaping treatment, which helps to maintain the continuity of the conductive layer and the stability of the conductive path, and has good protection;

[0014] At the same time, the wear-resistant layer is the same as the shaping layer, and both the wear-resistant layer and the shaping layer are polyurethane coating layers or acrylic coating layers or silicone resin coating layers, which are arranged outside the wire body to provide better weather resistance, mechanical strength, chemical resistance, wear resistance and corrosion resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the utility model.

[0016] Figure numerals: wire body-1, conductive layer-2, wear-resistant layer-3, shaping layer-4. DETAILED DESCRIPTION Embodiment 1:

[0017] like Figure 1 As shown, this embodiment proposes: an antistatic yarn, including a yarn body 1 (which may be the "carbon nanotube yarn" proposed in the background art or ordinary cotton, polyester or nylon yarn, etc.);

[0018] A conductive layer 2 is provided outside the wire body 1 (the conductive layer 2 is a copper nanowire coating, etc., which has low cost, good conductive effect, and strong antistatic property). During the treatment, the conductive layer 2 can be formed by soaking in a "silver nanowire dispersion" in the background technology, etc.;

[0019] A wear-resistant layer 3 is fixedly arranged outside the conductive layer 2, and is used to protect the conductive layer 2 and the wire body 1;

[0020] It also includes a shaping layer 4 fixedly arranged between the wire body 1 and the conductive layer 2, and the shaping layer 4 is a soft shaping layer (the conductive layer 2 is sandwiched and shaped in this way, which helps to maintain the continuity of the conductive layer 2 and the stability of the conductive path, and has good protection; at the same time, the shaping layer 4 is soft and can provide the wire body 1 with bending, that is, when the material is bent or physically deformed, the conductive layer 2 can also maintain good conductivity);

[0021] The wear-resistant layer 3 is the same as the shaping layer 4, and is convenient to set up, which is beneficial to the handling of the operation process. Embodiment 2:

[0022] like Figure 1 As shown, the difference between it and embodiment 1 is that: the wear-resistant layer 3 and the shaping layer 4 are both coating layers, and the process of setting and processing is relatively simple, which can be done by immersion, coating, etc.;

[0023] The wear-resistant layer 3 and the shaping layer 4 are both polyurethane coating layers, acrylic coating layers, silicone resin coating layers, etc., and are arranged outside the wire body 1 to provide better weather resistance, mechanical strength, chemical resistance, wear resistance and corrosion resistance;

[0024] The applied polyurethane coating layer or acrylic coating layer or silicone resin coating layer can enhance the mechanical stability: it can be used as an intermediate adhesive layer, and has a high degree of adhesion to the wire body 1, the shaping layer 4, the conductive layer 2 and the wear-resistant layer 3 connected in sequence;

[0025] When in use, its buffering and elastic functions can absorb external stress and reduce damage to the structure of the wire body 1 and the conductive layer 2. The structure adapts well to deformation and is not easy to break.

[0026] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
