Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust-free paper, in particular to a tear-resistant composite dust-free paper. Background Art
[0002] Dust-free paper is often used for surface cleaning because it does not easily shed chips. Traditional dust-free paper is mostly made of materials such as wood pulp fibers. However, although traditional dust-free paper is popular in the field of surface cleaning because it does not easily shed chips, its tear resistance has certain limitations. Dust-free paper with wood pulp fibers as the main component has good water absorption and softness, but when faced with strong pulling force, the bonding force between its fibers is relatively weak, which can easily lead to tearing or breakage, thereby limiting its durability and stability during use.
[0003] Based on the above situation, in the prior art, a patent with publication number CN207916235U discloses a dust-free paper, comprising a polyester layer and a fiber woven layer as an outer layer and a water-absorbent layer as a middle layer, wherein the fiber woven layer is composed of a yarn core strip and a yarn mesh wrapped outside the yarn core strip, and the surfaces of the polyester layer and the fiber woven layer are coated with a rubber layer. The polyester layer and the fiber woven layer are composited with a water-absorbent layer structure, which has the characteristics of high structural strength, strong water absorption, wipe resistance, and strong dirt holding capacity. It can effectively prevent the dust-free paper from fluffing and powdering during the wiping process, has good tear resistance, and is not easy to break. The composite water-absorbent layer formed by the interaction of the strong water absorption and penetration layer and the low water absorption rate layer makes the liquid re-seepage rate of the wiped surface of the dust-free wiping paper small, and is suitable for wiping wet objects on the surface.
[0004] However, the dust-free paper in the above patent still has some shortcomings. The above dust-free paper adopts a sandwich composite structure in which a yarn core strip is wrapped with a gauze mesh on the outside in the fiber woven layer. However, the composite structure of the yarn core strip and the gauze mesh is affected by the properties of the material, resulting in insufficient tear resistance, which may still cause tearing when subjected to a large external force.

[0006] A tear-resistant composite dust-free paper comprises a dust-free paper layer, an anti-tear layer and a water-absorbing layer, wherein the anti-tear layer and the dust-free paper layer are sequentially arranged on the upper and lower sides of the water-absorbing layer along the thickness direction of the composite dust-free paper, an antibacterial layer and an antistatic layer are arranged between the dust-free paper layer and the anti-tear layer, a water guide groove is arranged through the antibacterial layer, the antistatic layer and the water-absorbing layer, the anti-tear layer is provided with a first fiber, a second fiber and a third fiber, and the first fiber, the second fiber and the third fiber are woven to form an anti-tear net.
[0007] Furthermore, the first fibers and the second fibers are perpendicular to each other and form a grid in a plain weave form, the third fibers are arranged on both sides of the second fibers, and the third fibers are cross-woven up and down and wound around the intersection of the grid formed by weaving the first fibers and the second fibers.

[0011] Furthermore, the water-conducting grooves in the tear-resistant layer are correspondingly arranged in the squares of the square grid.
[0012] Furthermore, the water absorbing layer is uniformly filled with high molecular water absorbing resin particles.
[0013] The beneficial effects of the utility model are:
[0014] The tear-resistant layer is a tear-resistant net woven from the first fiber, the second fiber and the third fiber, which effectively improves the overall strength and tear-resistant ability of the dust-free paper and prevents tearing caused by excessive local force.

DETAILED DESCRIPTION
[0018] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.
[0019] like Figures 1 to 2 As shown, the utility model provides a technical solution: a tear-resistant composite dust-free paper, comprising a dust-free paper layer 1, an anti-tear layer 4 and a water-absorbing layer 5, the anti-tear layer 4 and the dust-free paper layer 1 are sequentially arranged on the upper and lower sides of the water-absorbing layer 5 along the thickness direction of the composite dust-free paper, an antibacterial layer 2 and an antistatic layer 3 are arranged between the dust-free paper layer 1 and the anti-tear layer 4, a water guide groove 6 is arranged through the antibacterial layer 2, the antistatic layer 3 and the water-absorbing layer 5, the anti-tear layer 4 is provided with a first fiber 41, a second fiber 42, and a third fiber 43, and the first fiber 41, the second fiber 42, and the third fiber 43 are woven to form an anti-tear net 44.
[0020] The tear-resistant layer 4 is woven from the first fibers 41, the second fibers 42 and the third fibers 43 to form an anti-tear net 44, wherein the first fibers 41 and the second fibers 42 are perpendicular to each other to form a grid 45, and the third fibers 43 are cross-woven and wound around the intersection of the grid 45. This structure enables the composite dust-free paper to have a strong tear-resistant performance and can withstand a large external force without being easily damaged. The water-absorbing layer 5 is evenly filled with polymer absorbent resin particles, which has good water absorption, can effectively absorb and lock liquid, reduce liquid reverse osmosis, and keep the surface of the dust-free paper layer 1 dry. The water-guiding grooves 6 arranged throughout each functional layer can quickly guide the liquid to the water-absorbing layer 5, so that The liquid can be quickly dispersed and absorbed, which improves the overall water absorption performance. The antibacterial layer 2 is a silver ion antibacterial agent coating. The antibacterial layer 2 provides antibacterial function, which can effectively prevent the growth of bacteria on the dust-free paper and maintain the hygiene and safety of the dust-free paper. The antistatic layer 3 selects alkali metal salts of alkyl sulfonic acids as antistatic agents, so that the antistatic layer 3 can reduce the generation of static electricity. The wavy texture 11 on the side of the dust-free paper layer 1 away from the antibacterial layer 2 increases the friction coefficient of the surface and improves the wiping effect. The antibacterial layer 2 and the antistatic layer 3 are coated by a coating method. The bonding between the dust-free paper layer 1 and the antibacterial layer 2 and the bonding between the anti-tear layer 4 and the water-absorbing layer 5 are all bonded by adhesives.
[0021] As one of the preferred embodiments of the present invention, Figure 2As shown, the first fiber 41 and the second fiber 42 are perpendicular to each other and form a square grid 45 in a plain weave form. The third fiber 43 is disposed on both sides of the second fiber 42. The third fiber 43 is woven and wound crosswise up and down at the intersections of the square grid 45 formed by the weaving of the first fiber 41 and the second fiber 42. The first fiber 41 and the second fiber 42 are made of composite fibers, and the third fiber 43 is made of ultra-high molecular weight polyethylene fiber.
[0022] The first fiber 41 and the second fiber 42 of the tear-resistant layer 4 are perpendicular to each other and woven into a square grid 45 in a plain weave form, providing good stability and support for the tear-resistant layer 4. The third fiber 43 is disposed on both sides of the second fiber 42 and is woven and wound crosswise up and down at the intersections of the square grid 45, effectively enhancing the firmness and tear resistance of the overall structure. The above weaving method not only increases the interaction force between the fibers but also enables the entire tear-resistant layer 4 to more effectively disperse and resist the tensile force when subjected to an external force, thereby enhancing its tear resistance.
[0023] The composite fiber of the first fiber 41 and the second fiber 42 is formed by twisting polyester fiber and spandex fiber. The polyester fiber has good tensile strength, while the spandex fiber has good elasticity. The composite fiber formed by twisting the two maintains high strength. The first fiber 41 and the second fiber 42 are woven to form a square grid 45, which not only effectively improves the tear resistance of the tear-resistant layer 4 but also endows the tear-resistant layer 4 with a certain elasticity, enabling the tear-resistant layer 4 to better adapt to various deformations during use and maintain the stability of the structure. The addition of the third fiber 43 and its interweaving with the square grid 45 form a tear-resistant net 44, further enhancing the tear resistance of the tear-resistant layer 4. The third fiber 43 is made of ultra-high molecular weight polyethylene fiber, which has high strength and can further enhance the tear resistance of the tear-resistant layer 4.
[0024] As one of the preferred embodiments of the present invention, as Figure 1 and Figure 2 shown, one end of the water guide groove 6 is placed on the surface of the antibacterial layer 2, and the other end of the water guide groove 6 is placed inside the water absorption layer 5. The water guide groove 6 in the tear-resistant layer 4 is correspondingly disposed in the squares of the square grid 45.
[0025] The water guide groove 6 serves as a channel for liquid transmission, and can quickly guide the liquid from the surface of the dust-free paper layer 1 or the antibacterial layer 2 to the inside of the water-absorbing layer 5, so that when the composite dust-free paper comes into contact with the liquid, it can quickly disperse and guide the liquid to the water-absorbing layer 5, effectively reducing the residence time of the liquid on the surface and keeping the surface dry. By placing the other end of the water guide groove 6 inside the water-absorbing layer 5 and connecting with the polymer absorbent resin particles in the water-absorbing layer 5, the water guide groove 6 can ensure that the liquid is efficiently absorbed by the water-absorbing layer 5, effectively improving the water absorption efficiency of the entire composite dust-free paper. The water guide groove 6 is correspondingly arranged in the square of the grid 45, which helps to quickly transmit and evenly distribute the liquid. At the same time, it can also reduce the resistance when water passes through the anti-tear layer 4, thereby further improving the efficiency of the composite dust-free paper in absorbing liquid.
[0026] As one of the preferred embodiments of the present invention, Figure 1 As shown, the surface of the dust-free paper layer 1 facing away from the antibacterial layer 2 is made of a wavy texture 11 using embossing technology. On the one hand, the wavy texture 11 increases the surface area of the dust-free paper layer 1 to a certain extent. The increased surface area may help to improve the adsorption capacity of the paper or the contact area with other substances, thereby increasing the cleaning and wiping effects of the dust-free paper. On the other hand, when the composite dust-free paper is used to absorb or wipe liquid, the wavy texture 11 helps to promote the distribution of the liquid. After the liquid contacts the wavy texture 11, it is easier to flow and diffuse along the grooves or raised parts of the texture, thereby accelerating the absorption speed and efficiency of the liquid.
[0027] As one of the preferred embodiments of the utility model, the water-absorbing layer 5 is uniformly filled with high-molecular water-absorbing resin particles. Since the water-absorbing layer 5 can quickly absorb and lock moisture to keep the surface dry, the high-molecular water-absorbing resin particles in the water-absorbing layer 5 can effectively prevent moisture from penetrating into other layers, thereby protecting the overall structure of the composite dust-free paper from damage.
[0028] When the composite dust-free paper absorbs liquid, the liquid first contacts the surface of the dust-free paper layer 1. The wavy texture 11 on the surface of the dust-free paper layer allows the liquid to diffuse and distribute faster along its grooves. The liquid penetrates the dust-free layer paper 1 and contacts the antibacterial layer 2. The liquid moves downward along the water guide groove 6 that is set throughout. One end of the water guide groove 6 is placed on the surface of the antibacterial layer 2, and the other end is placed inside the water absorption layer 5, so that the liquid can be quickly guided to the water absorption layer 5. The water absorption layer 5 is evenly filled with high molecular water absorption resin particles. When the liquid enters the water absorption layer 5 through the water guide groove 6, the high molecular water absorption resin particles will quickly absorb the water, so that the liquid is quickly absorbed by the dust-free paper.
[0029] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
