Description

Technical Field

[0001] The utility model relates to the field of fabrics, and more particularly to a composite non-woven fabric. Background Art

[0002] Currently, most non-woven fabrics used for lining are made of chemical fibers, which are relatively dry. Therefore, in the same dry external environment, static electricity will be generated in the fabrics due to friction between the fabrics or external adsorption during use. Utility Model Content

[0003] The purpose of the present utility model is to overcome the deficiencies of the above-mentioned prior art and provide a composite non-woven fabric, wherein a conductive mesh is added between two layers of non-woven fabric, and the conductive mesh is embedded in the base fabric layer to reduce the surface resistance of the non-woven fabric, so that static charge can leak, and a moisture storage portion is formed on the base fabric layer. In a dry external environment, the moisture generated by the human body is stored, thereby increasing the humidity of the fiber, thereby reducing the generation and accumulation of static electricity, and forming a protective layer on the outside of the conductive mesh. The protective layer is made of cotton fiber, which not only enables the conductive mesh to continue to maintain conductivity, but also increases the fiber humidity through the standard moisture regain of the cotton fiber, thereby reducing the generation of static electricity, and connects the warp and weft yarn interlaced layer between the two layers of non-woven fabric to increase the strength of the entire fabric.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0014] In summary, the present invention has the following beneficial effects:

[0015] By adding an antistatic layer between the base fabric layer and the protective layer, the antistatic layer embeds the conductive mesh into the base fabric layer, thereby reducing the surface resistance of the non-woven fabric, and forming a moisture storage part in the base fabric layer. The moisture storage part stores the water vapor generated by the human body, and in a dry external environment, the fiber contains moisture, thereby reducing the generation and accumulation of static electricity. The protective layer is formed by cotton fibers, which not only protects the conductive layer but also increases the fiber humidity, thereby reducing the generation of static electricity. The antistatic layer is interwoven with warp and weft yarns and connects the base fabric layer and the protective layer, thereby increasing the strength of the three layers.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1 —6 shows, a composite non-woven fabric includes a base fabric layer 10, an antistatic layer 20, and a protection layer 30 arranged in sequence from the inside to the outside. The antistatic layer 20 includes a conductive net 201 and a connection area 202. The antistatic layer 20 is formed by the interweaving of warp yarns and weft yarns. The antistatic layer 20 takes 6 warp yarns and 6 weft yarns as a cycle, and the warp yarns adopt conductive yarns, and the weft yarns adopt polyester fibers. "■" indicates that the warp yarn forms a warp point on the weft yarn, and "□" indicates that the warp yarn forms a weft point under the weft yarn. The first warp yarn and the first weft yarn form a warp point and form weft points with the second - 6th weft yarns. The second warp yarn and the second and 6th weft yarns form warp points and form weft points with the first, third - fifth weft yarns. The third warp yarn and the third and fifth weft yarns form warp points and form weft points with the first - second, fourth, and 6th weft yarns. The fourth warp yarn and the fourth weft yarn form a warp point and form weft points with the first - third, fifth - sixth weft yarns. The fifth warp yarn and the third and fifth weft yarns form warp points and form weft points with the first - second, fourth, and 6th weft yarns. The sixth warp yarn and the second and 6th weft yarns form warp points and form weft points with the first, third - fifth weft yarns. Therefore, the warp points are interwoven to form the conductive net 201, and are distributed in a rhombus shape in the antistatic layer 20. Thus, at the intersection points of the conductive yarns of the rhombic conductive net 201, the conductive yarns can be overlapped with each other, thereby reducing the resistance on the surface of the non-woven fabric, and the weft points are interwoven to form the connection area 202. Because the conductive net 201 adopts conductive yarns and the connection area 202 adopts polyester fibers, and the yarn count of the conductive yarn is thicker than that of the polyester fiber, therefore, the density of the fine yarn count of the polyester fiber is used, so that the conductive yarn is extruded due to the thick yarn count, and thus the formed conductive net 201 is higher than the connection area 202 and呈冂字形 (it seems there is a wrong character here, assuming it should be in a specific shape description). After the antistatic layer 20 formed by interweaving is flipped 180 degrees in the horizontal direction, the conductive net 201呈凵字形 (also seems wrong, assuming it should be in a specific shape description). Therefore, the antistatic layer 20 can be嵌合连接 (it seems there is a wrong expression here, assuming it should be a proper connection method) with the base fabric layer 10. At the same time, the top of the conductive net 201 can be connected in the conductive net groove 111 through gluing, protecting the conductive net 201 from being exposed on the surface, thereby increasing the practicability of the conductive net 201.

[0025] It should be noted that there seem to be some incorrect or unclear expressions in the original text such as "呈冂字形" and "嵌合连接" which might need to be further clarified in the original Chinese for a more accurate translation. Also, the repeated "呈凵字形" might be a mistake in the original.The base fabric layer 10 is made of polyester fibers formed into a non-woven fabric by directional web laying. Therefore, the base fabric layer 10 forms an electrostatic channel 101 through lamination and shaping. The electrostatic channels 101 are distributed in a diamond shape on the base fabric layer 10. The electrostatic channel 101 includes a conductive network groove 111 and a conductive network protection area 110. The conductive network protection area 110 is in a U-shaped form, and the height of the U-shaped form formed by the conductive network protection area 110 is the same as the height of the U-shaped form formed by the inversion of the conductive network 201, both being 0.25 mm. Therefore, the conductive protection area 110 is fitted with the U-shaped form formed by the inversion of the conductive network 201, and the top of the conductive network protection area 110 is adhesively connected to the connection area 202. Thus, when the antistatic layer 20 is fitted and connected to the base fabric layer 10, the conductive network 201 is embedded in the conductive network groove 111, reducing the exposure of the conductive network 201. And the conductive network 201 is connected to the conductive network groove 111, so the conductive network 201 and the conductive network groove 111 form an overlap, reducing the static electricity generated by the friction of the base fabric layer 10. The width of the electrostatic channel 101 is greater than the width of the conductive network 201, ensuring that the conductive network 201 is within the conductive network groove 111, increasing the service life of the conductive network 201.

[0026] The base fabric layer 10 further includes a base portion 102 and a moisture storage portion 103. The moisture storage portion 103 includes an adsorption area 130 and a storage area 131. The moisture storage portion 103 is located within the diamond shape formed by the electrostatic channels 101. The width of the base portion 102 is the same as the width of the storage area 131. Both the conductive network protection area 110 and the adsorption area 130 are higher than the base portion 102, and the conductive network protection area 110 is higher than the adsorption area 130. The conductive network protection area 110 is connected to the antistatic layer 20. Therefore, a space is formed between the base portion 102, the moisture storage portion 103 and the antistatic layer 20. Thus, when the external environment is humid, the static electricity generated by the friction between the fabric and the human body is adsorbed by the polyester fibers in the adsorption area 130 of the moisture storage portion 103, and at the same time, the charge flows in the storage area 131. An air circulation is formed within the space, so the water vapor brought by the humid external air can carry away some charges, reducing the charge accumulation of the fabric. When the external environment is dry, the charges wandering within the space are neutralized by the conductive network 201 of the antistatic layer 20, reducing the static electricity of the fabric. Both the conductive network protection area 110 and the adsorption area 130 are higher than the base portion 102, and the conductive network protection area 110 is higher than the adsorption area 130. Therefore, the base fabric layer 10 forms unevenness, reducing the contact area when the base fabric layer 10 is used, and thus reducing the static electricity generated by friction.

[0027] The protective layer 30 is a plain non-woven fabric formed by straight-laid cotton fibers, and is connected to the anti-static layer 20 by sewing. Because the protective layer 30 is the outermost layer and is formed by straight-laid cotton fibers, when the air is humid, the protective layer 30 can also reduce the accumulation and generation of static electricity on the surface of the fabric by absorbing external moisture. The base fabric layer 10 and the protective layer 30 are both non-woven fabrics. The structure of the non-woven fabric is not formed by fiber interweaving, so the air permeability can be guaranteed. The anti-static layer 20 is located between the base fabric layer 10 and the protective layer 30. While protecting the conductive mesh 201, the conductive mesh 201 can also provide anti-static effects to the base fabric layer 10 and the protective layer 30, so that the fabric always maintains anti-static properties.

[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
