Description

Technical Field

[0001] This application relates to the field of membrane fabric technology, and in particular to a strong composite membrane fabric and a locally reinforced face mask. Background Technology

[0002] The mask sheet is the carrier of the essence in a facial mask, and its material and structure directly affect the user experience and the retention and absorption of the essence. Traditional mask sheets are mostly of uniform thickness and can be applied directly to the face, wrapping moisturizing and functional essences. As people's demand for personalized facial care has developed, different people have different needs for intensive care in key areas such as the forehead, eye area, corners of the mouth, nasolabial folds, and cheekbones. Targeted intensive skincare is needed in these key areas. To address this, many manufacturers have produced products that incorporate one or more layers of mask sheet in specific areas to increase the liquid carrying capacity. This allows for a higher concentration of active ingredients in these key areas, achieving targeted skincare needs.

[0003] Currently, composite membrane fabrics are mostly laminated using a hydroentanglement process. However, if there are many layers or differences in the substrate materials of the membrane fabric, the lamination effect of the hydroentanglement process is not good. The edges of the composite layers are prone to lifting, curling, or falling off, failing to achieve a good bonding effect. The bonding strength of the laminated membranes in some areas is poor, which will seriously affect the user experience of locally reinforced membrane fabrics. Utility Model Content

[0004] Therefore, the purpose of this invention is to address the issue that the edges of existing composite membrane fabrics are prone to peeling or detachment, resulting in poor adhesion. This invention provides a strong composite membrane fabric and a locally reinforced mask. The composite membrane fabric of this invention exhibits high interfacial bonding strength, excellent composite strength, and is less prone to delamination and peeling.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A high-strength composite membrane fabric includes a base layer and a surface layer, and also includes an intermediate composite layer, wherein the intermediate composite layer includes a burr fiber layer, and the two sides of the burr fiber layer have a plurality of irregular burrs.

[0007] This invention utilizes the burrs in the intermediate burr fiber layer to grip and bond the upper and lower base layers and surface layer. After lamination, the irregular burrs insert into the fiber gaps between the base layer and surface layer, forming a better gripping force and enhancing the interface bonding. The resulting laminated membrane has good strength and is less prone to delamination and edge curling. The lamination method can be hot-press lamination. Because the burr fiber layer shrinks when heated, the ends of the irregular burrs shrink and deform during the hot-pressing process, causing the burrs inserted into the pores of the base layer and surface layer to deform and shrink. The burr ends will form a certain deformation, thereby achieving the purpose of physical lamination. Compared with ordinary physical hot-press lamination, the laminated membrane has better adhesion without the use of adhesives, achieving strong lamination. The lamination method can also be achieved through double-sided hydroentangling. When performing double-sided hydroentangling lamination, the burr ends of the burr fiber layer are driven into the fiber gaps between the base layer and surface layer under the impact of water flow, which can also achieve the purpose of lamination. The resulting laminate has superior adhesion strength compared with traditional multi-layer fiber lamination.

[0008] Furthermore, the burrs on each side are multi-directionally intersecting. The multi-directional intersecting burrs in the burr fiber layer create a claw-like effect, enabling them to penetrate the pores of the base layer and surface layer from different angles, achieving better gripping force.

[0009] It should be noted that the production of the burr fiber layer can be achieved by multi-directional spraying and interweaving of short microfibers or synthetic fibers, or by hydroentangling.

[0010] Furthermore, the burr portion is curved. This curvature provides better gripping effect; the burr tip, once inserted into the pores of the base layer and surface layer, is less likely to detach, resulting in better gripping force on the base layer and surface layer after lamination, enhancing interfacial bonding and achieving a strong lamination effect.

[0011] Furthermore, the maximum thickness of the burr fiber layer is 0.02 mm to 0.10 mm.

[0012] Furthermore, the fineness of the burr fiber layer is 0.3Td~1.0Td.

[0013] It should be noted that the thickness of the burr fiber layer should not be too large, otherwise it will affect the overall performance of the composite membrane. After repeated experiments and tests, the maximum thickness of the burr fiber layer, including the burr portion, was controlled within the range of 0.02mm to 0.10mm, and the fineness of the burr fiber layer was controlled within the range of 0.3Td to 1.0Td. This ensures good adhesion and bonding, enabling the composite of most membrane substrates with the best composite strength.

[0014] Furthermore, the burred fiber layer is a layer of ethylene and / or polyester fibers. Ethylene or polyester fibers, or a mixture of ethylene and / or polyester fibers, will shrink and deform after reaching a certain high temperature. Using ethylene and / or polyester fibers as the burred fiber layer allows for the composite of multilayer membrane fabrics using a hot-pressing process.

[0015] Furthermore, the intermediate composite layer also includes adhesive particles attached to the burrs.

[0016] Furthermore, the adhesive particles are water-based adhesives.

[0017] It should be noted that, in order to further enhance the composite strength and the composite effect of different membrane substrates, atomized particles of water-based adhesive are sprayed onto the burr fiber layer. These particles are environmentally friendly, pollution-free, and have high bonding strength. In the hot-pressing composite process, water is used as the dispersion medium, and no volatile organic compounds are released after hot pressing, further enhancing the interfacial bonding force after composite.

[0018] Furthermore, the base layer and / or surface layer are non-woven fabric layers, silk layers, fruit fiber layers, bio-fiber layers, Tencel plant fiber layers, viscose fiber layers, or microfiber layers.

[0019] Furthermore, the surface layer includes at least one layer, and when the number of layers of the surface layer is greater than one, adjacent surface layers are also composited through the burr fiber layer.

[0020] For different usage requirements, multiple layers need to be combined. The burr fiber layer can be used as a composite layer between two surface layers, or as a composite layer between a surface layer and a bottom layer. The composite effect is good and the bonding strength is high.

[0021] This utility model also provides a localized strengthening mask, wherein the mask adopts the strong composite membrane fabric as described above, and the surface layer is bonded to the forehead area, and / or the eye area, and / or the corner of the mouth area, and / or the nasolabial fold area and / or the apple cheek area through the burr fiber layer.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This invention utilizes the burrs in the intermediate fiber layer to grip and bond the upper and lower base layers and the surface layer. After lamination, the irregular burrs will insert into the fiber gaps between the base layer and the surface layer, forming a better gripping force and enhancing the interface bonding. The resulting laminated membrane has good composite strength and is less prone to delamination and edge curling. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] Example 1

[0035] like Figure 1 and Figure 2As shown, a high-strength composite membrane fabric includes a base layer 1 and a surface layer 2, and also includes an intermediate composite layer. The intermediate composite layer includes a burr fiber layer 3, and the two sides of the burr fiber layer 3 have several irregular burrs 31.

[0036] like Figure 3 As shown, the burrs 31 on each side are multi-directionally intersecting. The multi-directionally intersecting burrs 31 of the burr fiber layer 3 form a claw-like effect, which can penetrate into the pores of the base layer 1 and the surface layer 2 from different angles to achieve better gripping force.

[0037] It should be noted that the production of the burr fiber layer 3 can be achieved by multi-directional spraying and weaving of short microfibers or synthetic fibers, or by hydroentangling.

[0038] like Figure 3 As shown, the burr 31 has a curved shape. The curved shape provides a better gripping effect. After the end of the burr 31 penetrates the pores of the base layer 1 and the surface layer 2, it is not easy to fall out. After lamination, it has a better gripping force on the base layer 1 and the surface layer 2, enhances the interface bonding, and achieves a strong lamination effect.

[0039] In this embodiment, the maximum thickness of the burr fiber layer 3 is 0.02mm~0.10mm.

[0040] In this embodiment, the fineness of the burr fiber layer 3 is 0.3Td~1.0Td.

[0041] It should be noted that the thickness of the burr fiber layer 3 should not be too large, otherwise it will affect the overall performance of the composite thick film cloth. After repeated experiments and tests, the maximum thickness of the burr fiber layer 3, including the thickness of the burr 31 part, is controlled within the range of 0.02mm to 0.10mm, and the fineness of the burr fiber layer 3 is controlled within the range of 0.3Td to 1.0Td. This ensures good adhesion and bonding, enabling the composite of most film cloth substrates, and achieving the best composite strength.

[0042] In this embodiment, the burr fiber layer 3 is a layer of ethylene and / or polyester fibers. Ethylene or polyester fibers, or a mixture of ethylene and / or polyester fibers, will shrink and deform after reaching a certain high temperature. Using ethylene and / or polyester fibers as the burr fiber layer 3 allows for the composite of multilayer membrane fabrics using a hot-pressing composite process.

[0043] The composite method in this embodiment is hot-pressing composite. Since the burr fiber layer 3 shrinks when heated, the ends of the irregular burrs 31 shrink and deform during the hot-pressing process, causing the burrs 31 that penetrate into the pores of the base layer 1 and the surface layer 2 to deform and shrink. The ends of the burrs 31 will form a certain deformation, thereby achieving the purpose of physical composite. Moreover, compared with the composite film cloth of ordinary physical hot-pressing composite, it has better adhesion without the use of adhesives, achieving strong composite.

[0044] The advantage of this embodiment is that the burrs 31 of the intermediate burr fiber layer 3 are used to grip the upper and lower base layers 1 and the surface layer 2. After the composite is formed, the irregular burrs 31 will be inserted into the fiber gaps between the base layer 1 and the surface layer 2 to form a better gripping force, enhance the interface bonding, and the composite membrane fabric has good composite strength and is not prone to delamination and edge curling.

[0045] Example 2

[0046] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0047] like Figure 3 As shown, the intermediate composite layer also includes adhesive particles 4 attached to the burrs 31.

[0048] In this embodiment, the adhesive particles 4 are water-based adhesives.

[0049] The composite method in this embodiment is hot-pressing composite. Since the burr fiber layer 3 shrinks when heated, the ends of the irregular burrs 31 shrink and deform during the hot-pressing process, causing the burrs 31 that penetrate into the pores of the base layer 1 and the surface layer 2 to deform and shrink. The ends of the burrs 31 will form a certain deformation, thereby achieving the purpose of physical composite. Moreover, compared with the composite film cloth of ordinary physical hot-pressing composite, it has better adhesion without the use of adhesives, achieving strong composite.

[0050] It should be noted that, in order to further enhance the composite strength and the composite effect of different membrane substrates, atomized particles of water-based adhesive are sprayed onto the burr fiber layer 3. This is environmentally friendly, pollution-free, and has high bonding strength. In the hot-pressing composite process, water is used as the dispersion medium, and no volatile organic compounds are released after hot pressing, further enhancing the interfacial bonding force after composite.

[0051] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0052] Example 3

[0053] This embodiment is similar to Embodiment 1, except that:

[0054] In this embodiment, the base layer 1 is a non-woven fabric layer.

[0055] In this embodiment, the surface layer 2 is a non-woven fabric layer.

[0056] In this embodiment, surface layer 2 is a single-layer structure.

[0057] The composite method in this embodiment is hot-pressing composite. Since the burr fiber layer 3 shrinks when heated, the ends of the irregular burrs 31 shrink and deform during the hot-pressing process, causing the burrs 31 that penetrate into the pores of the base layer 1 and the surface layer 2 to deform and shrink. The ends of the burrs 31 will form a certain deformation, thereby achieving the purpose of physical composite. Moreover, compared with the composite film cloth of ordinary physical hot-pressing composite, it has better adhesion without the use of adhesives, achieving strong composite.

[0058] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0059] Example 4

[0060] This embodiment is similar to Embodiment 1, except that:

[0061] In this embodiment, the base layer 1 is a silk layer.

[0062] In this embodiment, the surface layer 2 has a double-layer structure, consisting of an ultra-fine fiber layer superimposed with a silk layer, and the ultra-fine fiber layer superimposed with the silk layer is also composited with a burr fiber layer.

[0063] For different usage requirements, multiple layers 2 need to be combined. Both the burr fiber layer 3 and the composite layer 2 can be used as composite layers between two layers 2, or as composite layers between the top layer 2 and the bottom layer. The composite effect is good and the bonding strength is high.

[0064] The composite method in this embodiment is hot-pressing composite. Since the burr fiber layer 3 shrinks when heated, the ends of the irregular burrs 31 shrink and deform during the hot-pressing process, causing the burrs 31 that penetrate into the pores of the base layer 1 and the surface layer 2 to deform and shrink. The ends of the burrs 31 will form a certain deformation, thereby achieving the purpose of physical composite. Moreover, compared with the composite film cloth of ordinary physical hot-pressing composite, it has better adhesion without the use of adhesives, achieving strong composite.

[0065] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0069] The composite method in this embodiment is hot-pressing composite. Since the burr fiber layer 3 shrinks when heated, the ends of the irregular burrs 31 shrink and deform during the hot-pressing process, causing the burrs 31 that penetrate into the pores of the base layer 1 and the surface layer 2 to deform and shrink. The ends of the burrs 31 will form a certain deformation, thereby achieving the purpose of physical composite. Moreover, compared with the composite film cloth of ordinary physical hot-pressing composite, it has better adhesion without the use of adhesives, achieving strong composite.

[0073] The composite method in this embodiment is hot-pressing composite. Since the burr fiber layer 3 shrinks when heated, the ends of the irregular burrs 31 shrink and deform during the hot-pressing process, causing the burrs 31 that penetrate into the pores of the base layer 1 and the surface layer 2 to deform and shrink. The ends of the burrs 31 will form a certain deformation, thereby achieving the purpose of physical composite. Moreover, compared with the composite film cloth of ordinary physical hot-pressing composite, it has better adhesion without the use of adhesives, achieving strong composite.
