Description

Technical Field

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

[0002] Dust-free paper, also known as dry-laid nonwoven fabric, is a type of dry-laid nonwoven fabric. Dust-free paper has unique physical properties, characterized by high elasticity, softness, excellent hand feel and drape, high water absorption and good water retention, low dust and anti-static properties, and is widely used in sanitary care products, special medical products, industrial wiping products and other fields. However, common dust-free paper has gradually become difficult to meet the increasingly high performance requirements of these products, especially in the field of industrial wiping. The wiping position usually adheres to more liquids such as oil and water or relatively stubborn solids, requiring dust-free paper to have higher absorption and wear resistance. Therefore, functional research and development of dust-free paper is usually carried out. The preparation of functional dust-free paper generally involves compounding a functional layer structure on the finished product of dust-free paper to improve the various properties of dust-free paper.

[0003] Based on the above situation, the Chinese patent with announcement number CN218399687U discloses a new type of dust-free paper, including absorbent cotton and a dust-free paper body arranged on the outside of the absorbent cotton, the interior of the dust-free paper body is a accommodating cavity, the absorbent cotton is located inside the accommodating cavity, the dust-free paper body is provided with multiple water suction ports connected to the accommodating cavity, the dust-free paper body includes a dust-free paper layer, the dust-free paper layer is arranged on the outside of the absorbent cotton, the outer wall of the dust-free paper layer is provided with a non-woven fabric layer, and a hot-melt fiber layer is provided between the non-woven fabric layer and the dust-free paper layer; the dust-free paper achieves higher water absorption performance through the cooperation of the absorbent cotton and the multiple water suction ports, but the density and bonding strength of the fibers inside the dust-free paper are low, and the dust-free paper will swell after absorbing water and the internal fiber structure is still in a relatively loose state, the stability of the internal structure of the dust-free paper will be reduced, resulting in the dust-free paper being more prone to deformation, delamination, breakage, etc. during use, so the above-mentioned dust-free paper still has room for improvement.

[0018] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is 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 Figure 1 、 2 As shown, a composite cloth containing dust-free paper includes a dust-free paper layer 1, a guide layer 2, an absorption layer 3, an oil-locking layer 4, and a waterproof back film 5. The dust-free paper layer 1, the guide layer 2, the absorption layer 3, the oil-locking layer 4, and the waterproof back film 5 are bonded and fixed in sequence along the thickness direction. The dust-free paper layer 1 is provided with a wiping surface 11 on the side away from the guide layer 2. The wiping surface 11 is formed by uniformly coating the surface of the dust-free paper layer 1 with a wear-resistant coating and then curing it. A plurality of absorption holes 31 are provided on the surface of the absorption layer 3, and a plurality of channels are provided inside the absorption layer 3 to connect the absorption holes 31 to each other.

[0020] The composite cloth of the utility model is a composite material based on dust-free paper, which is mainly used in the field of industrial wiping as an industrial wiping product. In the composite cloth, the dust-free paper layer 1, the guide layer 2, the absorption layer 3, the oil-locking layer 4, and the waterproof back film 5 are bonded and fixed in sequence along the thickness direction by adhesives, so that one side of the dust-free paper layer 1 is set as the wiping surface. The dust-free paper layer 1 adopts common dust-free paper, which is composed of 50%-85% wood pulp fiber and 15%-50% hot-melt fiber. The dust-free paper itself is used to wipe the surface of the material to be wiped, and the dust-free paper is dust-free. The surface of the paper layer 1 is uniformly coated with a wear-resistant coating and then solidified to form a wiping surface 11. The wear-resistant coating can be a fluorocarbon coating, silicone coating or other coating with good weather resistance. By coating the wear-resistant coating on the side of the dust-free paper layer 1 away from the guide layer 2 and waiting for the coating to solidify, a wiping surface 11 with good wear resistance can be formed. When the composite cloth needs to remove stubborn impurities or stains on the surface of an object, the wiping surface 11 can increase the strength and friction coefficient of the surface of the dust-free paper layer 1, thereby improving the durability of the composite cloth and the efficiency of removing impurities or stains on the surface of an object by wiping.

[0021] After adopting the above structure, it needs to be further explained that the guide layer 2 is composed of a number of guide fibers extending along the thickness direction. The guide fibers can be hollow fibers or special-section fibers. The hollow fibers are provided with through holes extending along the length direction of the fibers, and the surfaces of the special-section fibers are provided with a number of guide grooves extending along the length direction of the fibers. When the composite cloth wipes an object with liquid attached to the surface, the liquid will be absorbed into the dust-free paper layer 1, and then a capillary effect will be generated through the through holes inside the hollow fibers or the guide grooves on the surface of the special-section fibers, so that the liquid will quickly penetrate along the length direction of the fibers, so that the liquid is quickly guided to the absorption layer 3, thereby improving the absorbency of the composite cloth to the liquid and allowing the liquid on the surface of the object to be quickly wiped clean.

[0022] After adopting the above structure, it needs to be further explained that the absorption layer 3 preferably adopts a foaming material such as polyurethane sponge. The foaming material forms a number of pore structures during the foaming process, so that a number of absorption holes 31 and channels connecting the absorption holes 31 to each other are formed on the surface of the absorption layer 3. The absorption layer 3 quickly absorbs the liquid guided by the guide layer 2 inside through the absorption holes 31 and the internal channels. The absorption layer 3 can absorb a large amount of liquid through the internal pore structure, thereby further improving the absorbency of the composite cloth to the liquid, so that the composite cloth can absorb more liquid.

[0023] After adopting the above structure, it needs to be further explained that the structure of the oil-locking layer 4 is preferably composed of a gel wrapped with oil-absorbing paper, and the silicone gel is preferably CF3 modified silicone gel with excellent adsorption performance for oil. The silicone gel has good lipophilicity and makes the surface of the oil-locking layer 4 lipophilic. The oil-water separation can be achieved inside the composite cloth through the oil-locking layer 4. When the liquid attached to the surface of the object to be wiped is an oil-water mixture, the composite cloth will wipe the object in the process of the oil-water mixture being absorbed by the dust-free paper layer 1, the guide layer 2 for diversion, and the absorption layer 3 in turn. After that, the oil-locking layer 4 absorbs the oil component in the oil-water mixture into the interior, thereby improving the wiping effect of the composite cloth on the oil-water mixture or oily liquid on the surface of the object, and improving the use range and cleaning effect of the composite cloth.

[0024] After adopting the above structure, it needs to be further explained that the waterproof back film 5 preferably adopts a waterproof breathable film. The waterproof breathable film is formed by adding fillers to the raw materials and stretching them in the subsequent molding process to form a number of air holes that allow gas to penetrate but not liquid to penetrate. When using a composite cloth to wipe the object, it is usually necessary to apply a certain pressure to the composite cloth. When the composite cloth is squeezed, part of the air inside the composite cloth can be discharged through the air holes of the waterproof back film 5, which is beneficial for the composite cloth to absorb the liquid into the interior along the dust-free paper layer 1, the guide layer 2, the absorption layer 3, and the oil-locking layer 4 in sequence through the internal structure, thereby improving the composite cloth's absorption efficiency of the liquid, and the liquid will not penetrate the waterproof back film 5 to penetrate into the back of the composite cloth, thereby improving the cleanliness of the side of the composite cloth that is not used for wiping.

[0025] To sum up, the composite cloth of the present invention is mainly used as an industrial wiping product. The dust-free paper layer 1 is used as the side of the composite cloth to wipe objects. The surface is provided with a wiping surface 11 with high strength and high friction coefficient. The wiping surface 11 can efficiently remove impurities or stains on the surface of the object and improve the durability of the composite cloth. The liquid absorbed by the dust-free paper layer 1 is quickly guided to the internal absorption layer 3 through the guide layer 2 inside the composite cloth to be absorbed. At the same time, the oil-locking layer 4 improves the absorption of the oil-water mixture or oily liquid inside the composite cloth, thereby improving the absorption of the composite cloth to the liquid and improving the cleaning effect of the composite cloth on the wiped object.

[0026] like Figure 1 、 2 As shown, as one of the preferred embodiments of the present invention, the dust-free paper layer 1 is provided with a toughening layer 6 on the side away from the wiping surface 11. The toughening layer 6 is in the shape of a mesh structure, and the toughening layer 6 completely covers the surface of the dust-free paper layer 1; the utility model forms the toughening layer 6 by weaving a plurality of fine wire materials in a warp and weft manner. The fine wire material is selected from nylon fibers, polyester fibers and other fibers with higher strength and is made by twisting operations. Since the interior of the dust-free paper layer 1 is mainly composed of wood pulp fibers, its structural firmness is relatively poor. The toughening layer 6 can form traction on the fibers of the dust-free paper layer 1 to prevent the dust-free paper layer 1 from being torn under the action of external force, thereby improving the strength of the dust-free paper layer 1 and the durability of the composite cloth.

[0027] like Figure 3 As shown, as the second preferred embodiment of the present invention, the edge of the dust-free paper layer 1 extends outward and is folded over to be fixedly connected to the waterproof back film 5. The dust-free paper layer 1 and the waterproof back film 5 together wrap the guide layer 2, the absorption layer 3, and the oil-locking layer 4. After the dust-free paper layer 1 adopts this structure, the side of the composite cloth in the thickness direction will be wrapped by the dust-free paper layer 1, and the outer surface of the side of the composite cloth will also be covered by the wiping surface 11, so that the composite cloth can better wipe the edges and corners of the object, thereby improving the cleanliness of the surface of the wiped object.

[0028] like Figure 1 As shown, as one of the preferred embodiments of the present invention, a plurality of liquid-permeable holes 12 are penetrated on the surface of the dust-free paper layer 1. The liquid-permeable holes 12 can be formed by mechanically punching the dust-free paper layer 1. When the dust-free paper layer 1 comes into contact with the liquid, the liquid-permeable holes 12 on the surface can form a capillary effect to efficiently absorb the liquid into the composite cloth, thereby improving the efficiency of the composite cloth in absorbing liquid.

[0029] like Figure 1As shown, as one of the preferred embodiments of the present invention, the outer surface of the absorption layer 3 is wrapped with an antibacterial coating 32, and the antibacterial coating 32 is formed by uniformly coating the outer surface of the absorption layer 3 with an antibacterial agent and then curing it; since the absorption layer 3 has a rich pore structure inside, water vapor and the like are easily accumulated inside the absorption layer 3 and difficult to discharge, and the antibacterial agent is selected from one of an ammonium salt cationic antibacterial agent, a polyhexamethylene biguanide hydrochloride antibacterial agent, and a silver ion antibacterial agent. After the antibacterial agent is cured, the antibacterial coating 32 is formed, which has the function of killing bacteria and viruses, thereby avoiding the accumulation of bacteria inside the absorption layer 3 and the occurrence of odor, mildew, etc.

[0030] like Figure 1 As shown, as one of the preferred embodiments of the present invention, the absorption layer 3 is inlaid with a plurality of water-absorbing beads 33 on one side close to the oil-locking layer 4, and the surface of the water-absorbing beads 33 is hydrophilic; the water-absorbing beads 33 of the present invention are preferably water-absorbing resin, which has good hydrophilicity. The water-absorbing beads 33 can improve the absorption of liquid by the absorption layer 3, and the water-absorbing beads 33 will expand after absorbing water, thereby generating better support inside the composite cloth, avoiding the inside of the composite cloth being too soft and affecting the wiping effect on objects.

[0031] like Figure 1 、 2 As shown in Figure 3, as one of the preferred embodiments of the present invention, the waterproof back film 5 is provided with a Velcro 7 on the side away from the oil-locking layer 4, and the composite cloth can be fixed in a fixed structure similar to a brush handle. The fixed structure is provided with a Velcro on the other side that matches the Velcro 7 on the surface of the waterproof back film 5, so that the composite cloth can be fixed to the fixed structure through the Velcro 7. The user holds the fixed structure and wipes the object through the composite cloth, thereby better applying the wiping force during the wiping process.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
