Description

Technical Field

[0001] The utility model relates to the technical field of dust-free paper, in particular to a fiber suede dust-free paper. Background Art

[0002] Due to its characteristic of not being easy to shed flakes, dust-free paper is often used for cleaning the surface of objects. Traditional dust-free papers are mostly made of materials such as wood pulp fibers and polyester fibers. Although these materials have certain water absorption and adsorption properties, when faced with complex pollutants such as fine particles and oil stains, their adsorption ability is relatively limited. The surface tension and smoothness of the material itself may not be sufficient to effectively capture and fix these fine pollutants, resulting in poor cleaning effects; traditional dust-free papers are usually smooth on the surface, and the surface structure of traditional dust-free papers is relatively single, usually presenting a flat or slightly wrinkled form. This single structure makes it difficult for the dust-free paper to form an effective adsorption layer during the wiping process, unable to fully contact and adsorb pollutants. At the same time, the flat structure also limits the penetration ability of the dust-free paper into small gaps, making it difficult to achieve an ideal cleaning effect.

[0003] Based on the above situation, in the prior art, the patent with the publication number CN217319570U discloses a dust-free paper and airlaid composite wiping material, including a dust-free paper layer and a low-melting-point fiber layer. The dust-free paper and the low-melting-point fiber layer are bonded and fixed by heat bonding, and the low-melting-point fiber layer is made by the airlaid method. An absorbent layer is provided on the lower surface of the dust-free paper layer, antibacterial layers are coated on both the upper and lower surfaces of the absorbent layer, and an ultra-fine fiber suede layer is provided on the lower surface of the absorbent layer. The ultra-fine fiber suede layer is made of ultra-fine fiber suede cloth material. Compared with the smooth surface of the dust-free paper, the ultra-fine fiber fluff on the surface of the composite wiping material increases the contact surface and adhesion force to dust during wiping, enabling it to wipe more cleanly, and the suede surface is soft and will not scratch the product. When wiping with the side of the dust-free paper with the low-melting-point fiber layer, the wiping material is not only convenient for wiping stubborn stains, but also can wipe the surface of precise products that are prone to scratches, improving the applicability.

[0004] The above patent forms a cleaning material with better cleaning effect by compounding the dust-free paper with the ultra-fine fiber suede layer and the low-melting-point fiber layer. However, the composite wiping material in the above patent still has some deficiencies in combination with the actual situation. The above composite wiping material lacks corresponding anti-static measures or anti-static structures, making the surface of the above composite wiping material prone to static electricity when rubbed, reducing the applicability for cleaning electronic products. At the same time, the structural strength of the above composite wiping material is insufficient. After absorbing water, during a long-time wiping action, the composite wiping material may break. Summary of the Utility Model

[0005] In view of the technical deficiencies in the background art, the present utility model proposes a fiber suede dust-free paper. In order to further solve the above technical problems and meet the actual needs, the specific technical solutions are as follows:

[0006] A fiber suede dust-free paper, comprising a fiber suede cloth layer, a reinforcement layer, a water absorption layer, and a base paper layer. The fiber suede cloth layer, the reinforcement layer, the water absorption layer, and the base paper layer are sequentially arranged layer by layer along the thickness direction of the dust-free paper. The fiber suede cloth layer is provided with a base cloth layer. A flocking adhesive layer is coated on the upper surface of the base cloth layer, and a first antibacterial layer is coated on the lower surface of the base cloth layer. A number of suede fibers are implanted on the upper surface of the flocking adhesive layer. The reinforcement layer is provided with a number of reinforcing fibers. A second antibacterial layer is provided between the water absorption layer and the base paper layer. The base paper layer is a dust-free paper.

[0007] Further, an antistatic layer is provided between the base paper layer and the second antibacterial layer. The antistatic layer is an antistatic agent coating with a thickness of 50 - 100 microns.

[0008] Further, the suede fiber is any one of nylon fiber fluff, polyester fiber fluff, viscose fiber fluff, polyamide fiber fluff, or acrylic fiber fluff. The length of the suede fiber is 0.05 - 0.2 mm, and the fineness is 10 - 50 microns.

[0009] Further, the suede fiber and the base cloth layer are provided with uniformly attached antistatic agents. The antistatic agent is selected from any one of quaternary ammonium salt antistatic agents, alkyl sulfonate antistatic agents, alkyl sulfate antistatic agents, or alkyl phosphate antistatic agents.

[0010] Further, the reinforcement layer is formed into a reinforcement net by crisscrossing a number of reinforcing fibers. The reinforcing fiber is a carbon fiber with a diameter of 50 - 100 microns.

[0011] Further, both the first antibacterial layer and the second antibacterial layer are silver ion antibacterial coatings with a thickness of 50 - 70 microns.

[0012] Further, the thickness of the water absorption layer is 100 - 300 microns, and the water absorption layer is filled with a high molecular water absorbent resin.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The fiber suede dust-free paper of the present utility model has been double-optimized in terms of anti-static property and structural strength. By adding an anti-static layer between the base paper layer and the second antibacterial layer, the accumulation of static electricity is effectively inhibited. At the same time, the suede fibers and the base cloth layer are also evenly coated with an anti-static agent to further consolidate the anti-static performance. In terms of structural strength, the reinforcing layer is woven into a net by carbon fibers, which can improve the overall strength and durability, ensuring that the dust-free paper is not easily damaged during high-intensity use. The sequential arrangement of the fiber suede cloth layer, the reinforcing layer, the water-absorbing layer, and the base paper layer forms a stable and functionally distinct structural system, which not only retains the soft touch and high dust-absorbing ability but also significantly improves the structural stability and service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following describes the embodiments of the present utility model in conjunction with the accompanying drawings and related embodiments. The embodiments of the present utility model are not limited to the following embodiments, and the relevant necessary components involved in the present utility model should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0020] As Figures 1 to 3 shown, the present utility model provides a technical solution: a fiber suede dust-free paper, comprising a fiber suede cloth layer 1, a reinforcing layer 2, a water-absorbing layer 3, and a base paper layer 5. The fiber suede cloth layer 1, the reinforcing layer 2, the water-absorbing layer 3, and the base paper layer 5 are sequentially arranged layer by layer along the thickness direction of the dust-free paper. The fiber suede cloth layer 1 is provided with a base cloth layer 13. The upper surface of the base cloth layer 13 is coated with a flocking adhesive layer 12, and the lower surface of the base cloth layer 13 is coated with a first antibacterial layer 14. A number of suede fibers 11 are implanted on the upper surface of the flocking adhesive layer 12. The reinforcing layer 2 is provided with a number of reinforcing fibers 21. A second antibacterial layer 4 is provided between the water-absorbing layer 3 and the base paper layer 5. The base paper layer 5 is a dust-free paper.

[0021] In this utility model, the fiber suede cloth layer 1 serves as the surface layer of the dust-free paper. The suede fibers 11 on the surface of the fiber suede cloth layer 1 can effectively adsorb and lock dust and tiny particles during the wiping and cleaning process, significantly improving the cleaning efficiency. The first antibacterial layer 14 and the second antibacterial layer 4 can not only effectively inhibit the growth of microorganisms such as bacteria and molds, but also maintain a stable antibacterial effect for a long time. The reinforcing layer 2 is woven into a reinforcing mesh 22 by crisscrossing reinforcing fibers 21, which can effectively improve the overall structural strength of the dust-free paper, making it not easy to break or deform during use and extending its service life. The water absorption layer 3 can quickly absorb and lock liquids, keeping the surface of the dust-free paper dry, effectively broadening the applicable scenarios of the dust-free paper. The antistatic layer 6 and the antistatic agents uniformly attached to the suede fibers 11 and the base cloth layer 13 further consolidate the overall antistatic performance of the dust-free paper.

[0022] As a preferred embodiment of this utility model, as Figure 1 shown, an antistatic layer 6 is provided between the base paper layer 5 and the second antibacterial layer 4. The antistatic layer 6 is an antistatic agent coating with a thickness of 50 - 100 microns. The suede fibers 11 and the base cloth layer 13 are provided with uniformly attached antistatic agents, and the antistatic agent is selected from any one of quaternary ammonium salt antistatic agents, alkyl sulfonate antistatic agents, alkyl sulfate antistatic agents, or alkyl phosphate antistatic agents.

[0023] The antistatic agent used in the antistatic layer 6 is the same as the antistatic agents attached to the surfaces of the suede fibers 11 and the base cloth layer 13, and is selected from any one of quaternary ammonium salt antistatic agents, alkyl sulfonate antistatic agents, alkyl sulfate antistatic agents, or alkyl phosphate antistatic agents, preferably quaternary ammonium salt antistatic agents.

[0024] When the antistatic agent is applied to the surfaces of the suede fibers 11 and the base cloth layer 13, the antistatic agent can increase the conductivity or hygroscopicity of the surfaces of the suede fibers 11 and the base cloth layer 13, enabling the static charges on the surfaces of the suede fibers 11 and the base cloth layer 13 to be more easily conducted or dissipated into the air through the material surface or interior, thereby reducing the risk of static charge accumulation. The antistatic layer 6 can prevent the accumulation of static charges on the surface of the dust-free paper of the base paper layer 5. When the base paper layer 5 is rubbed, the static charges generated on the surface of the base paper layer 5 can be quickly released through the antistatic layer 6, achieving the effect of eliminating the static electricity of the base paper layer 5.

[0025] The antistatic agent selected is a quaternary ammonium salt antistatic agent. Quaternary ammonium salt antistatic agents usually have a relatively low surface resistance and high conductivity, and can quickly conduct or dissipate static charges into the air, thus effectively reducing the risk of static charge accumulation. At the same time, quaternary ammonium salt antistatic agents can maintain stable performance under various environmental conditions and are not easily affected by factors such as temperature and humidity, thereby ensuring long-term antistatic effects. In addition, quaternary ammonium salt antistatic agents are usually harmless to humans and the environment, meeting environmental protection and safety requirements, and can be used with confidence in various occasions.

[0026] As a preferred embodiment of the present utility model, the suede fiber 11 is any one of nylon fiber fluff, polyester fiber fluff, viscose fiber fluff, polyamide fiber fluff or acrylic fiber fluff. The length of the suede fiber 11 is 0.05 - 0.2 mm, and the fineness is 10 - 50 microns.

[0027] The suede fiber 11 can increase the contact area between the dust-free paper and dust particles or pollutants, improving the adsorption efficiency and stability. During the wiping process, the suede fiber 11 can quickly adsorb and fix dust, reducing the number of times and time of repeated wiping and improving the cleaning efficiency. The suede fiber 11 is preferably viscose fiber fluff, with a length of 0.05 mm and a fineness of 50 microns. Viscose fiber has good hygroscopicity and breathability, enabling the dust-free paper to absorb moisture more effectively while keeping the surface dry and comfortable. Viscose fiber fluff has a delicate and soft texture, enabling the dust-free paper to provide a softer and more comfortable touch during wiping or cleaning, reducing wear and scratches on the surface to be cleaned.

[0028] As a preferred embodiment of the present utility model, as Figure 2 shown, the reinforcing layer 2 is formed by interweaving a number of reinforcing fibers 21 vertically and horizontally to form a reinforcing net 22. The reinforcing fibers 21 are carbon fibers with a diameter of 50 - 100 microns.

[0029] The reinforcing layer 2 is formed by interweaving carbon fibers with a diameter of 100 microns vertically and horizontally to form a reinforcing net 22, which can increase the overall structural strength and durability of the dust-free paper. Carbon fiber, as the reinforcing fiber 21, has the characteristics of high strength and high modulus. When the carbon fibers are interwoven vertically and horizontally to form the reinforcing net 22, a stable skeleton structure can be formed, effectively resisting the action of external forces such as pressure, tension and tearing, thereby effectively improving the overall structural strength of the dust-free paper.

[0030] As a preferred embodiment of the present utility model, both the first antibacterial layer 14 and the second antibacterial layer 4 coatings are silver ion antibacterial coatings with a thickness of 50 - 70 microns.

[0031] The thicknesses of both the first antibacterial layer 14 and the second antibacterial layer 4 coating are silver ion antibacterial coatings with a thickness of 50 microns. Silver ions have broad-spectrum antibacterial properties and can effectively inhibit the growth and reproduction of microorganisms such as bacteria, molds, and viruses. In the first antibacterial layer 14, the silver ion antibacterial coating can continuously release silver ions, thereby protecting the base fabric layer 13. The second antibacterial layer 4 is arranged between the water-absorbing layer 3 and the base paper layer 5, which can further enhance the antibacterial performance of the dust-free paper and form a double antibacterial barrier with the first antibacterial layer 14 to further improve the antibacterial performance of the dust-free paper.

[0032] As a preferred embodiment of the present invention, the thickness of the water-absorbing layer 3 is 100 - 300 microns, and the water-absorbing layer 3 is filled with a high molecular weight water-absorbing resin; the water-absorbing layer 3 is filled with a high molecular weight water-absorbing resin with a thickness of 300 microns. The high molecular weight water-absorbing resin filled inside the water-absorbing layer 3 can improve the water absorption performance of the dust-free paper, maintain the cleaning effect, and enhance the usage experience. The high molecular weight water-absorbing resin has excellent water absorption ability and can quickly absorb and lock water. Therefore, when the dust-free paper comes into contact with liquid stains, it can quickly absorb and retain water, effectively preventing the spread of stains and keeping the surface clean. At the same time, the water retention performance of the high molecular weight water-absorbing resin also helps to prevent stains from being re-released onto the surface to be cleaned during the wiping process.

[0033] The production of the fiber suede dust-free paper of the present invention: A flocking adhesive layer 12 is evenly coated on the upper surface of the base fabric layer 13, and the selected suede fibers 11 are implanted into the flocking adhesive layer 12 by the method of electrostatic flocking to ensure uniform distribution of the fibers; a first antibacterial layer 14 is coated on the lower surface of the base fabric layer 13, using a silver ion antibacterial coating, using carbon fiber as the reinforcing fiber 21, and a reinforcing net 22 is formed by crosswise weaving, thereby obtaining a reinforcing layer 2. The reinforcing layer 2 is adhered to the lower surface of the first antibacterial layer 14 through an adhesive; an antistatic agent and a silver ion antibacterial agent are respectively coated on the upper surface of the base paper layer 5 to form an antistatic layer 6 and a second antibacterial layer 4 respectively. An adhesive is coated on the upper surface of the second antibacterial layer 4, and a high molecular weight water-absorbing resin is applied on the upper surface of the second antibacterial layer 4 to form a water-absorbing layer 3. An adhesive is applied on the lower surface of the reinforcing layer 2, and the lower surface of the reinforcing layer 2 is adhered to the upper surface of the water-absorbing layer 3, thereby obtaining the fiber suede dust-free paper. Then, the entire dust-free paper is flattened, dried, etc. to ensure tight bonding between layers and remove excess water and solvents to obtain the finished product of the fiber suede dust-free paper.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
