DETAILED DESCRIPTION OF THE INVENTION
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figures 1-5 , the present utility model provides an antistatic fabric containing metal fibers, including an upper woven fabric layer 1, a lower woven fabric layer 2, and a middle woven fabric layer 3. The upper woven fabric layer 1 and the lower woven fabric layer 2 are located on the upper and lower sides of the middle woven fabric layer 3. A binding edge 4 is sewn at the edges of the upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3. The upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3 together form a fabric body 5. Metal fiber conductive wires 6 are sewn inside the upper woven fabric layer 1 and the lower woven fabric layer 2. A decorative snap button cover 7 is installed on the upper woven fabric layer 1, and a decorative snap button base 8 is installed on the lower woven fabric layer 2;
[0027] A locking ball 9 is fixed at the bottom end of the decorative snap button cover 7, and a tie head 10 is fixed at the bottom end of the locking ball 9. A locking groove 11 is opened on the outer side of the upper end face of the decorative snap button base 8, and a locking ring 12 is fixed on the inner wall of the locking groove 11. An inner cavity 13 is opened between the decorative snap button cover 7 and the decorative snap button base 8. A limiting pressure plate 14 slides in the inner cavity 13 on one side of the decorative snap button cover 7. A finger pressure column 15 is fixed on the limiting pressure plate 14, and a finger pressure groove 16 is opened on the finger pressure column 15. An electrostatic capacitor 17 is installed on the inner bottom surface of the inner cavity 13 on one side of the decorative snap button base 8. A spring piece 18 is installed on the electrostatic capacitor 17. An upper contact groove 19 is opened above the spring piece 18, and a lower contact groove 20 is opened below the spring piece 18. An upper contact head 21 is installed inside the upper contact groove 19, and a lower contact head 22 is installed inside the lower contact groove 20. By knitting and fixing the metal fiber conductive wires 6 inside the upper woven fabric layer 1 and the lower woven fabric layer 2, and then knitting and fixing the upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3 together to form the fabric body 5, the antistatic ability of the fabric body 5 can be improved.
[0028] Furthermore, the upper woven fabric layer 1 and the lower woven fabric layer 2 are woven from warp and weft fiber textile lines, and the middle woven fabric layer 3 is woven from warp and weft polyester yarns. The middle woven fabric layer 3 is located between the upper woven fabric layer 1 and the lower woven fabric layer 2. The middle woven fabric layer 3 made of polyester can reduce the mutual friction between the upper woven fabric layer 1 and the lower woven fabric layer 2.
[0029] Further, the fabric body 5 is woven from an upper woven fabric layer 1, a lower woven fabric layer 2, and a middle woven fabric layer 3. The edges of the upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3 are locked and fixed to each other by a binding edge line 4, which facilitates locking and fixing the edges of the upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3 to each other through the binding edge line 4.
[0030] Further, the metal fiber conductive wires 6 are distributed in a snake shape inside the upper woven fabric layer 1 and the lower woven fabric layer 2, and the metal fiber conductive wires 6 are woven and fixed to the upper woven fabric layer 1 and the lower woven fabric layer 2. By distributing the metal fiber conductive wires 6 in a snake shape, the length of the metal fiber conductive wires 6 inside the upper woven fabric layer 1 and the lower woven fabric layer 2 can be increased, enabling the metal fiber conductive wires 6 to prevent static electricity at different positions of the upper woven fabric layer 1 and the lower woven fabric layer 2.
[0031] Further, the locking ring 12 is a circular elastic ring, the locking ball 9 is movably clamped with the locking ring 12, and the bottom end of the head 10 is needle-shaped. When the maximum outer diameter of the locking ball 9 passes through the locking ring 12, it can be movably clamped with the locking ring 12. The fabric body 5 can be easily punctured through the head 10, enabling the locking ball 9 to pass through the fabric body 5, so that the decorative snap button cover 7 and the decorative snap button base 8 can be installed and fixed on the fabric body 5. Both the decorative snap button cover 7 and the decorative snap button base 8 are made of acrylic material and have good insulation ability.
[0032] Further, the limiting pressure plate 14 is connected to the top end of the elastic piece 18, the bottom end of the elastic piece 18 is fixedly connected to the static capacitor 17, the upper contact groove 19 is adapted to the lower contact groove 20. When the upper contact groove 19 contacts the lower contact groove 20, the upper contact head 21 and the lower contact head 22 also contact each other. At this time, the upper contact head 21 and the lower contact head 22 are in a combined state, and the static electricity generated in the static capacitor 17 can be released.
[0033] Further, a conductive wire is provided inside the elastic piece 18, the upper contact head 21 and the lower contact head 22 are connected by the conductive wire, the upper contact head 21 contacts the lower contact head 22, and the lower contact head 22 is electrically connected to the static capacitor 17. The working principle of the static capacitor 17 is that charges will move under the action of force in an electric field. When there is a dielectric between conductors, the movement of charges is hindered, causing charges to accumulate on the conductors, resulting in the accumulation and storage of charges. This facilitates the formation of a closed loop among the static capacitor 17, the upper contact head 21, the lower contact head 22, and the conductive wire inside the elastic piece 18, and causes the static capacitor 17 to be short-circuited, thereby being able to release the static electricity generated in the static capacitor 17.
[0034] Further, one end of the metal fiber conductive wire 6 is electrically connected to the upper contact head 21, and the other end of the metal fiber conductive wire 6 is electrically connected to the electrostatic capacitor 17. The metal fiber conductive wires 6 in the upper woven fabric layer 1 are connected to the metal fiber conductive wires 6 in the lower woven fabric layer 2. Moreover, the other end of the metal fiber conductive wire 6 in the upper woven fabric layer 1 is electrically connected to the upper contact head 21, and the other end of the metal fiber conductive wire 6 in the lower woven fabric layer 2 is electrically connected to the electrostatic capacitor 17. Therefore, a closed circuit can be formed among the upper and lower groups of metal fiber conductive wires 6, the upper contact head 21, the lower contact head 22, and the electrostatic capacitor 17.
[0035] During use, the metal fiber conductive wire 6 is woven and fixed inside the upper woven fabric layer 1 and the lower woven fabric layer 2. Then, the upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3 are woven and fixed to each other to form the fabric body 5. The binding thread 4 can lock and fix the edges of the upper woven fabric layer 1, the lower woven fabric layer 2, and the middle woven fabric layer 3. The middle woven fabric layer 3 made of polyester can reduce the direct friction between the upper woven fabric layer 1 and the lower woven fabric layer 2, improving the comfort of the fabric body 5 during use. Then, a through hole with the same aperture size as the inner cavity 13 is punched on the surface of the fabric body 5 by a punching machine. One end of the metal fiber conductive wire 6 is connected to the upper contact head 21, and the other end of the metal fiber conductive wire 6 is connected to the electrostatic capacitor 17, forming a closed loop among the metal fiber conductive wire 6, the upper contact head 21, the lower contact head 22, and the electrostatic capacitor 17. At this time, the upper contact head 21 and the lower contact head 22 are in a separated and disconnected state. Then, the decorative snap button cover 7 and the decorative snap button base 8 are respectively placed on the upper and lower sides of the through hole of the fabric body 5, aligning the through hole with the inner cavity 13. Then, the decorative snap button cover 7 and the decorative snap button base 8 are pressed, so that the locking ball 9 drives the tying head 10 to pierce through the fabric body 5 and enter the locking groove 11, making the locking ball 9 and the locking ring 12 engage and fix with each other. Therefore, the decorative snap button cover 7 and the decorative snap button base 8 can be installed and fixed on both sides of the through hole of the fabric body 5. At this time, the part of the metal fiber conductive wire 6 exposed outside the fabric body 5 can be hidden inside the inner cavity 13 through the decorative snap button cover 7 and the decorative snap button base 8, and the connection between it and the fabric body 5 can be sealed through the decorative snap button cover 7 and the decorative snap button base 8. Therefore, when static electricity is generated on the fabric body 5, the generated static electricity can be transmitted to the electrostatic capacitor 17 through the metal fiber conductive wire 6, and the electrostatic capacitor 17 stores the generated static electricity. Then, a person places a finger in the finger pressure groove 16 and presses the finger pressure post 15. At this time, the finger pressure post 15 generates a pressure on the elastic piece 18 through the limit pressing plate 14, causing its top end to move downward. When the upper contact groove 19 contacts the lower contact groove 20, the upper contact head 21 and the lower contact head 22 also contact each other. At this time, the upper contact head 21 and the lower contact head 22 are in a combined state. At this time, a closed loop is formed among the electrostatic capacitor 17, the upper contact head 21, the lower contact head 22, and the conductive wire inside the elastic piece 18, and the electrostatic capacitor 17 is short-circuited, so that the static electricity generated in the electrostatic capacitor 17 can be released, thus achieving the anti-static effect on the fabric body 5. When the static electricity in the electrostatic capacitor 17 is released, the person's hand releases the finger pressure post 15. At this time, the elastic piece 18 expands and makes the upper contact head 21 and the lower contact head 22 separate from each other, so that the upper contact head 21 and the lower contact head 22 are again in a separated and disconnected state, and a closed loop is formed again among the metal fiber conductive wire 6, the upper contact head 21, the lower contact head 22, and the electrostatic capacitor 17, so as to continuously conduct anti-static treatment on the fabric body 5.
[0036] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
