Abstract
Description
Technical Field
[0001] This utility model belongs to the field of carpet base fabric technology, specifically relating to a composite flat yarn carpet base fabric. Background Technology
[0002] Static electricity poses numerous hazards. The first hazard stems from the interaction of charged bodies. The second major hazard is the potential for static sparks to ignite flammable materials, causing explosions, or to damage various electronic devices. For example, it can damage integrated circuits and precision electronic components, or accelerate component aging, reducing production yield. In production environments with flammable and explosive materials, or those containing dust or oil mist, it can easily cause explosions and fires.
[0003] The dangers of static electricity are well-known, and people have begun to implement various levels of anti-static measures and projects, such as installing anti-static flooring. However, in some older buildings used as machine rooms, power distribution rooms, or warehouses storing flammable materials, the economic cost of renovating the floor and installing anti-static flooring is too high. In such cases, laying anti-static carpets can be used instead of anti-static flooring, thus saving costs.
[0004] However, some existing antistatic carpets have complex structures and many production processes, while others have conductive materials on the carpet surface, resulting in poor grounding performance. Utility Model Content
[0005] This utility model provides a composite flat yarn carpet base fabric to solve the technical problems of existing antistatic carpets, such as complex structure, multiple production processes, or conductive materials on the carpet surface, resulting in poor grounding effect.
[0006] This utility model includes:
[0007] Several warp threads;
[0008] A plurality of weft yarns are interwoven with a plurality of warp yarns;
[0009] Both the warp and the weft yarns are flat yarns, and at least one of the warp and the weft yarns is a composite flat yarn;
[0010] The composite flat filament includes a substrate layer, and at least one of the top and bottom surfaces of the substrate layer is covered with a conductive layer.
[0011] Furthermore, the conductive layer is a conductive coating or a conductive plating. The beneficial effect of this step is to make the composite flat wire conductive through a conductive coating or conductive plating.
[0012] Furthermore, the width of the warp and weft yarns is 2±0.2mm. The beneficial effect of this step is to ensure conductivity as much as possible without affecting the tufting effect, to prevent excessive wear of the conductive layer during the intertwining of the warp and weft yarns in the weaving process, and to facilitate slitting into strips.
[0013] Furthermore, it also includes several metal foils, which are spaced apart on any one or both sides of the composite flat yarn carpet base fabric. The beneficial effect of this step is that during the carpet tufting process, the carpet material fills into the carpet base fabric, which is equivalent to increasing the distance between the warp and weft yarns and affecting the conductivity. The metal foils can compensate for the conductivity of the base fabric.
[0014] Furthermore: the length of the metal foil is the same as the length of the warp yarn, the width of the metal foil is 5~8cm, and the weft spacing of the metal foil is 38±2cm, 58±2cm or 78±2cm. The advantage of this step is that the metal foil and the weft yarn are the same length, and the metal foil can be continuously fed during the base fabric weaving process, enabling continuous production; while the distance between the metal foils can be selected according to the layout of the site and equipment.
[0015] Furthermore, the composite flat yarn carpet base fabric has binding fabric on both warp sides. The beneficial effect of this step is to maintain the integrity of the composite flat yarn carpet base fabric by using the binding fabric.
[0016] The beneficial effects of this utility model are:
[0017] 1. The composite base fabric provided in this application has conductivity, which can reduce the number of production steps of antistatic carpets, simplify the structure of antistatic carpets, and produce low-cost antistatic carpets, making it suitable for users with antistatic needs but limited antistatic budgets.
[0018] 2. This application is in direct contact with the ground and can provide good conductivity, ensuring that carpets made with this application have good antistatic properties. Attached Figure Description

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0025] Example
[0026] like Figure 1 As shown, the composite flat yarn carpet base fabric provided by this utility model includes:
[0027] Several warp threads;
[0028] Several weft yarns are interwoven with several warp yarns. Generally, in order to balance economy and tufting effect, the base fabric is woven using a plain weave technique.
[0029] Both the warp and weft yarns are flat yarns, and at least one of the warp and weft yarns is a composite flat yarn. The flat yarns have a good forming effect after weaving, and neither the warp nor the weft yarns are prone to shifting, resulting in good stability of the base fabric.
[0030] The composite flat filament includes a substrate layer, and at least one of the top and bottom surfaces of the substrate layer is covered with a conductive layer.
[0031] The antistatic carpet produced using this application adds conductive fibers to the carpet pile or makes the carpet pile conductive through modification, blending, or other means. Then, the pile is tufted onto the carpet base fabric, and the pile and the carpet base fabric form a conductive path, which can conduct static electricity from people or objects walking on the carpet to the ground, thus achieving the antistatic function.
[0032] Antistatic carpets use composite flat yarn carpet base fabric 1, which simplifies their structure, reduces production costs, and expands their application range.
[0033] In one embodiment, the conductive layer is a conductive coating or a conductive plating. The conductive coating is generally a coating made of graphite, metal ions or materials with conductive properties, which is obtained after drying and hardening. The conductive plating is generally a metal plating achieved by PVD or CVD, and can be copper, silver, etc. In addition, metal foils such as aluminum foil can be bonded by adhesive. All of the above methods are to make the composite flat wire conductive.
[0034] In one embodiment, considering that if the width of the warp and weft yarns is too thick, the gaps in the finished composite flat yarn carpet base fabric 1 will be reduced under the same weight, affecting the tufting effect; if the width of the warp and weft yarns is too thin, the warp and weft yarns will have a high density and a high degree of intertwining, which may wear down the conductive layer on the surface of the warp and weft yarns and affect the conductivity effect; therefore, after many production trials and inspections, the width of the warp and weft yarns is limited to 2±0.2mm.
[0035] In one embodiment, the material further includes several metal foils 2, preferably aluminum foil, which is inexpensive and has good conductivity. The several metal foils 2 are spaced apart and disposed on any one or both sides of the composite flat yarn carpet base fabric 1.
[0036] During the carpet tufting process, carpet material is filled into the composite flat yarn carpet base fabric 1, which is equivalent to increasing the distance between the warp and weft yarns. In fact, during the needle punching process, the warp or weft yarns may break, which will affect the conductivity. The metal foil 2 can compensate for the conductivity of the composite flat yarn carpet base fabric 1 to ensure that the conductivity is not affected.
[0037] Considering the ease of production of the composite flat yarn carpet base fabric 1, based on the above technical solution, the length of the metal foil 2 is the same as the length of the warp yarn. During the base fabric weaving process, the metal foil 2 and the warp yarn are fed in the same direction, and the warp yarn bobbin and the metal foil 2 roll can be fed together continuously, enabling continuous production. The distance between the metal foils 2 can be selected according to the layout of the site and equipment. For example, in some old houses, the floor is covered with wooden flooring or non-conductive floor tiles, etc., nails can be driven into the corresponding positions of the metal foil 2 to make it contact the ground. Therefore, the width of the metal foil 2 is limited to 5~8cm. Furthermore, the weft spacing of the metal foil 2 is set to 38±2cm, 58±2cm or 78±2cm to adapt to the specifications of common building materials on the market, such as 40*40cm, 60*60cm or 80*80cm, etc. In this way, the metal foil 2 can cover the seams of common building materials (nails are driven into the seams of building materials, which are easy to drive in and will not damage the original building materials or will reduce damage).
[0038] In one embodiment, the composite flat yarn carpet base fabric 1 has binding fabric on both warp sides to maintain the integrity of the composite flat yarn carpet base fabric 1.
[0039] The above embodiments disclose a composite flat yarn carpet base fabric, which is conductive in itself. By simply adding conductive materials to the pile to make the pile also conductive, the carpet made by combining the two can be conductive and achieve anti-static function.
[0040] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details.
