Description

Technical Field

[0001] The present application relates to the technical field of daily cosmetics, and in particular to a composite film cloth for air cushions. Background Art

[0002] In recent years, with the rapid development of the beauty and cosmetics industry, consumers have increasingly demanded higher standards for the texture, user experience, and effects of cosmetics. As a new cosmetic product, air cushion foundation has garnered widespread attention and popularity due to its lightweight, portable, and easy-to-use features. A common air cushion foundation is the mesh air cushion. Using mesh as a storage and distribution medium for liquid foundation, it offers greater capacity, is less susceptible to bacterial growth, and is more hygienic. To ensure that liquid foundation is more breathable and moisturizing after application, and that the liquid foundation quickly flows out when the mesh is pressed, mesh air cushions are manufactured using low-viscosity foundations and large-pore meshes. However, during shaking, sideways, or inversion, liquid foundation can easily leak through the mesh, causing pollution and waste. Alternatively, to prevent liquid foundation from seeping through during shaking, sideways, or inversion, mesh air cushions are manufactured using high-viscosity foundations and small-pore meshes. However, this often results in discharging issues, such as delayed and uneven discharging, which negatively impacts the user experience. Utility Model Content

[0003] In order to improve the problem that liquid foundation is not discharged in a timely and uniform manner during use, which affects the user experience, the present application provides a composite membrane cloth for an air cushion.

[0004] The composite membrane cloth for air cushions provided in this application adopts the following technical solution:

[0005] A composite membrane cloth for an air cushion comprises a fabric layer and a microporous membrane layer, the fabric layer and the microporous membrane layer being bonded together by hot-melt bonding. The fabric layer is a stretch fabric serving as a base layer capable of quickly and evenly releasing liquid foundation. The microporous membrane layer is a SEBS membrane having a plurality of irregular micropores. When the composite membrane cloth is pressed, the micropores open, allowing liquid foundation to pass quickly and evenly through the micropores and the fabric layer in turn. When no external force is applied, the micropores can prevent liquid foundation from leaking.

[0006] By adopting the above technical solution, there are several irregular micropores on the SEBS membrane, so that when the membrane cloth is pressed, the micropores are forced to open, so that the foundation liquid can pass through quickly and evenly in sequence. In the natural state, without external force, the pore size of the micropores is not enough to prevent the foundation liquid from leaking, thereby having a barrier effect on the foundation liquid.

[0007] Optionally, the fabric layer is one or more of woven fabric and knitted fabric, and is woven from 30-150D yarn.

[0008] By adopting the above technical solution, the fabric layer is elastic and breathable, and the warp and weft are interlaced to make it firm, crisp and not easy to deform.

[0009] Optionally, the yarn is made of a blend of spandex or one or more of spandex with a content of at least 10%, polyester, nylon, acrylic, modal, acetate, viscose, cupro and cotton.

[0010] By adopting the above technical scheme, spandex is used as a necessary raw material for the yarn of the fabric layer in this scheme. Since spandex has good elasticity, high extensibility, high elastic recovery rate, and is not easy to wrinkle, the composite membrane cloth can quickly return to its original state when pressed. In addition, spandex is durable and not easy to age, has stable chemical properties, and has high biocompatibility. Knitted fabric is preferably used for the fabric layer. The structure of the knitted fabric itself is composed of a series of coils strung together. With a series of coils, the foundation liquid can pass through the knitted fabric more smoothly when pressed.

[0011] Optionally, the fabric layer is elastic, has an elastic recovery rate greater than 95%, a thickness of 0.3-1 mm, and a gram weight of 80-300 g / m2.

[0012] By adopting the above technical solution, the excellent elastic recovery rate helps the composite membrane cloth to return to its original state after pressing the foundation. If the thickness and gram weight of the fabric layer are too small, the foundation will easily leak; if the thickness and gram weight are too large, the foundation will be discharged slowly during use, affecting the user experience.

[0013] Optionally, the microporous membrane layer is a SEBS membrane with a thickness of 0.1-1 mm and a plurality of irregularly shaped micropores provided on the membrane.

[0014] By employing this technical solution, the irregular micropores distributed throughout the SEBS membrane are crucial for controlling the permeability of foundation material. When the composite membrane is pressed, the micropores open, allowing liquid foundation to flow quickly and evenly through the micropores and then through the fabric layer 1. When no external force is applied, the micropores prevent liquid foundation from leaking. If the SEBS membrane is too thin, foundation is susceptible to leakage. If it is too thick, the micropores won't fully open when the composite membrane is pressed, affecting discharge speed and uniformity.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] The fabric layer in the utility model serves as a base layer, which is elastic and can quickly and evenly release liquid foundation; a number of irregularly shaped micropores are distributed on the SEBS membrane. When the composite membrane cloth is pressed, the micropores open, and the liquid foundation can pass through the micropores and the fabric layer in turn quickly and evenly. When no external force is applied, the micropores can block the leakage of the liquid foundation. Even if it is shaken, placed sideways or inverted, the liquid foundation is unlikely to overflow, which can avoid waste and pollution caused by leakage of the liquid foundation.

Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0019] Reference numerals: 1. fabric layer; 2. microporous membrane layer. DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 This application is described in further detail.

[0021] The embodiments of the present application disclose a composite membrane cloth for an air cushion.

[0022] Reference Figure 1 The utility model provides a composite membrane cloth for air cushion with quick discharge and anti-leakage, which is composed of a fabric layer 1 and a microporous membrane layer 2. Its structure is as follows: Figure 1 As shown in the figure, fabric layer 1 is a stretch fabric that serves as the base layer, enabling rapid and even release of liquid foundation. Microporous membrane layer 2 is a SEBS membrane with a number of irregularly shaped micropores. When the composite membrane is pressed, the micropores open, allowing liquid foundation to pass quickly and evenly through the micropores and then through fabric layer 1. When no external force is applied, the micropores prevent liquid foundation from leaking.

[0023] The fabric layer 1 of the present invention is one or more of woven fabrics and knitted fabrics, woven from 30-150D yarns. The yarns are blended from spandex or at least 10% spandex with one or more of polyester, nylon, acrylic, modal, acetate, viscose, cupro and cotton fibers. Spandex is used as a necessary raw material for the yarn of the fabric layer 1 in this embodiment because spandex has good elasticity, high extensibility, high elastic recovery rate, and is not easy to wrinkle, so that the composite membrane cloth can quickly return to its original state when pressed. In addition, spandex is durable and not easy to age, has stable chemical properties, and has high biocompatibility. The fabric layer 1 is preferably a knitted fabric, and the structure of the knitted fabric itself is formed by a series of coils strung together, with a series of coils, so that the foundation liquid can pass through the knitted fabric more smoothly when pressed.

[0024] Fabric layer 1 is elastic, with an elastic recovery rate exceeding 95%. Its thickness ranges from 0.3-1mm and its weight ranges from 80-300g / m². This excellent elastic recovery helps the composite film return to its original state after applying foundation. If the thickness and weight of fabric layer 1 are too small, foundation may leak easily. If they are too large, foundation dispensing may be slow, impacting the user experience.

[0025] The microporous membrane layer 2 of the present invention is a SEBS membrane. The SEBS membrane is a high-performance plastic elastomer membrane material made of SEBS (styrene-ethylene-butylene-styrene block copolymer) as the basic material. It has a low modulus and does not affect the overall feel of the composite membrane cloth when compounded with the fabric layer 1. It combines the elasticity of rubber and the processability of plastic, and has excellent flexibility, weather resistance, UV resistance, chemical corrosion resistance, non-toxicity, environmental protection and excellent biocompatibility. It can be safely used in the field of daily cosmetics, especially in the field of composite membrane cloth for air cushions.

[0026] The SEBS membrane is 0.1-1mm thick and features a number of irregularly shaped micropores. These irregular micropores are crucial for controlling the permeability of foundation material. When the composite membrane is pressed, the micropores open, allowing liquid foundation to flow quickly and evenly through the micropores and then through the fabric layer 1. When no external force is applied, the micropores prevent liquid foundation from leaking. If the SEBS membrane is too thin, foundation is susceptible to leakage. If it is too thick, the micropores will not fully open when the composite membrane is pressed, affecting discharge speed and uniformity.

[0027] The implementation principle of the composite membrane cloth for air cushion in the embodiment of the present application is as follows: the fabric layer serves as the base layer, which is elastic and can quickly and evenly release liquid foundation; a number of irregularly shaped micropores are distributed on the SEBS membrane. When the composite membrane cloth is pressed, the micropores open, and the liquid foundation can pass through the micropores and the fabric layer in turn quickly and evenly. When no external force is applied, the micropores can prevent the liquid foundation from leaking. Even if it is shaken, placed sideways or inverted, the liquid foundation is unlikely to overflow, which can avoid waste and pollution caused by leakage of the liquid foundation.
