Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and in particular to a highly effective antibacterial wet wipe for cleaning. Background Technology

[0002] Most existing antibacterial wet wipes achieve their antibacterial effect by spraying an antibacterial solution onto a nonwoven fabric. For example, CN113855611B discloses a household antibacterial wet wipe, comprising a tissue base and an antibacterial solution. The antibacterial solution is prepared through the following steps: Step 1: At a temperature of 60°C, sorbitol and deionized water are mixed, and then aloe vera extract, cocoyl diethanolamide, anhydrous ethanol, PEG-40 hydrogenated castor oil, 1,2-propanediol, and an antibacterial additive are added and stirred until completely dissolved. Step 2: Heating is stopped, and the temperature is allowed to drop below 40°C. The pH value is adjusted to 6-6.5. The tissue base is prepared through the following steps: Pure cotton spunlace nonwoven fabric and nanocellulose solution are mixed, soaked for 10 minutes, then removed and hung for 2 minutes, and then dried at 30°C to constant weight to obtain the tissue base. The antibacterial additive is prepared through the following steps: Step S11: Acetone and chitosan are mixed, and then triglycerides are added. Ethylamine was added to an acetone solution of succinic anhydride and refluxed for 6 hours to obtain solid a; Step S12: Solid a was mixed with thionyl chloride and reacted at 45°C for 4 hours to obtain intermediate b; Intermediate b, L-ascorbic acid, and dichloromethane were stirred and mixed, and triethylamine was added, and the mixture was stirred and reacted for 10 hours to obtain intermediate c; Step S13: Intermediate c was mixed with isopropanol and an isopropanol solution of 2,3-epoxypropyltrimethylammonium chloride was added at 50°C. The antibacterial additive was obtained by stirring and reacting at 60℃ for 24 hours. The antibacterial solution included the following raw materials by weight: 100-110 parts deionized water, 0.3-1 parts sorbitol, 30-60 parts anhydrous ethanol, 1-5 parts cocoyl diethanolamide, 0.2-3 parts PEG-40 hydrogenated castor oil, 1-3 parts aloe vera extract, 0.05-0.2 parts 1,2-propanediol, and 8-10 parts antibacterial additive; the mass fraction of the nanocellulose solution was 3-5%.

[0003] When used, wet wipes are used to wipe the surface of objects to remove stains. The antibacterial liquid on the wet wipes remains on the surface of the objects, giving them antibacterial properties for a short time. However, wet wipes only remove stains from the surface of objects by means of their surface roughness, so their cleaning efficiency is low and they are not able to carry away a lot of stains, which means that the stains are not completely removed from the surface of the objects. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides a highly efficient antibacterial wet wipe, which mainly solves the problems of low cleaning efficiency and poor cleaning effect of existing antibacterial wet wipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A highly effective antibacterial wet wipe includes a wet wipe body, defined as extending longitudinally along the length direction and transversely along the width direction. The wet wipe body includes a mesh layer, a surface layer, an absorbent layer, and a base fabric layer. The absorbent layer is laminated on the upper surface of the base fabric layer, and the surface layer is laminated on the upper surface of the absorbent layer. The surface layer has mesh grooves in a mesh structure pressed on its upper surface, dividing the surface layer into several absorbent units. Several inclined and parallel strip grooves are pressed on the surface of the surface layer within the absorbent units. The depth of the mesh grooves is greater than the depth of the strip grooves. The mesh layer has through holes distributed in a matrix. The mesh layer is embedded in the mesh grooves of the surface layer and is laminated and connected to the surface layer. The through holes are distributed at the absorbent units. The hardness of the mesh layer is greater than that of the surface layer.

[0007] Furthermore, the strip groove is provided with connecting holes that penetrate the surface layer.

[0008] Furthermore, a groove is recessed on the upper surface of the adsorption layer at a location corresponding to the connecting pores, and the groove allows the surface layer and the adsorption layer to be combined to form a storage cavity.

[0009] Furthermore, the two ends of the strip groove are connected to the grid groove, and the angle between the strip groove and the transverse central axis of the wet paper towel body is 25° to 75°.

[0010] Furthermore, the adsorption units of the surface layer have through holes protruding from the mesh layer.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This highly efficient antibacterial wet wipe, through the composite structure design of the grid layer and the surface layer, the adsorption units formed by the grid grooves can improve the storage capacity and distribution uniformity of the liquid medicine or cleaning agent, and the inclined strip grooves can increase the surface friction coefficient and enhance the mechanical removal force of stains; the composite structure of the base fabric layer and the adsorption layer enhances the mechanical strength of the wet wipe and prevents fiber shedding during wiping; the grid layer is harder than the surface layer and can form a supporting skeleton to prevent the decrease in cleaning efficiency caused by the deformation of the multi-layer structure, so that the wet wipe itself has high cleaning efficiency and good cleaning effect. Attached Figure Description

[0012] Figure 1 This is a top view of an embodiment of the present invention.

[0013] Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure at point AA. Detailed Implementation

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] The embodiment of this utility model is as follows:

[0016] refer to Figure 1 and Figure 2 As shown, a highly effective antibacterial wet wipe includes a wet wipe body 100, defined as extending longitudinally along the length direction and laterally along the width direction. The wet wipe body 100 includes a mesh layer 1, a surface layer 2, an absorbent layer 3, and a base fabric layer 4. The absorbent layer 3 is laminated to the upper surface of the base fabric layer 4, and the surface layer 2 is laminated to the upper surface of the absorbent layer 3. A mesh groove 5 with a mesh structure is pressed onto the upper surface of the surface layer 2. The surface layer 2 is divided into several adsorption units 20 by the grid groove 5. Two inclined and parallel strip grooves 6 are pressed on the upper surface of the surface layer 2 and located in the adsorption unit 20. The depth dimension of the grid groove 5 is greater than the depth dimension of the strip groove 6. The grid layer 1 has through holes 10 distributed in a matrix. The grid layer 1 is embedded in the grid groove 5 of the surface layer 2 and is compositely connected with the surface layer 2. The through holes 10 are distributed at the adsorption unit 20. The hardness of the grid layer 1 is greater than the hardness of the surface layer 2.

[0017] This highly effective antibacterial wet wipe features a composite structure design of a mesh layer 1 and a surface layer 2. The absorbent units 20 formed by the mesh grooves 5 can improve the storage capacity and distribution uniformity of the medicine or cleaning agent. The inclined strip grooves 6 can increase the surface friction coefficient and enhance the mechanical removal force of stains. The composite structure of the base fabric layer 4 and the absorbent layer 3 enhances the mechanical strength of the wet wipe and prevents fiber shedding during wiping. The mesh layer 1 is harder than the surface layer 2 and can form a supporting skeleton to prevent the decrease in cleaning efficiency caused by the deformation of the multi-layer structure. This makes the wet wipe body 100 highly efficient and effective in cleaning.

[0018] Furthermore, the strip groove 6 is provided with a connecting hole 7 that penetrates the surface layer. A groove 8 is recessed on the upper surface of the adsorption layer 3 at a location corresponding to the connecting hole 7. The groove 8 allows the surface layer 2 and the adsorption layer 3 to combine and form a storage cavity. The connecting hole 7 creates a through-channel between the surface layer 2 and the adsorption layer 3, accelerating the release of the stored liquid and preventing the retention of active ingredients due to excessive density of the adsorption layer 3. The storage cavity formed by the groove 8 has a slow-release function; when external pressure is applied, the stored cleaning agent can be released directionally through the connecting hole 7. This cavity can stably maintain the concentration of the disinfectant, and substances from mechanical glass surfaces can enter the storage cavity through the connecting hole 7, further enhancing the cleaning effect.

[0019] Furthermore, the two ends of the strip groove 6 are connected to the grid groove 5. The angle between the strip groove 6 and the transverse central axis of the wet wipe body 100 is 25° to 75°, preferably 50°. The tilt angle design of the strip groove 6 conforms to the ergonomic wiping trajectory, which can improve the effective cleaning stroke per unit area and balance the longitudinal tensile strength and transverse extensibility, preventing the structure of the wet wipe body 100 from tearing when wiping at an angle.

[0020] In this embodiment, the adsorption unit 20 of the surface layer 2 protrudes from the through-hole 10 of the mesh layer 1. The adsorption unit 20 protruding from the through-hole 10 forms a micro-protrusion structure, which increases the contact pressure with the skin / object surface to improve the cleaning power, and also creates a local negative pressure through the through-hole 10 to accelerate the seepage of the medicine. This design can significantly improve cleaning efficiency in scenarios with heavy oil stains such as kitchen wipes.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
