Description

Technical Field

[0001] The present application relates to the technical field of daily cosmetics, and in particular to a composite membrane cloth for air cushions that can be quickly pressed and discharged and is leak-proof. Background Art

[0002] In recent years, with the rapid development of the beauty and cosmetics industry, consumers' expectations for cosmetics' texture, user experience, and effects have become increasingly stringent. 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 type of 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 breathable and moisturizing after application, and that the liquid foundation quickly flows out when the mesh is pressed, manufacturers often use a low-viscosity foundation and a mesh with larger pores to produce mesh air cushions. However, when shaking, placing the cushions on their sides, or inverting them, the liquid foundation easily leaks through the mesh, causing pollution and waste. Alternatively, to prevent liquid foundation from seeping through during shaking, placing the cushions on their sides, or inverting them, manufacturers use a high-viscosity foundation and a mesh with smaller pores. However, this often results in uneven and delayed discharge when pressed, impacting the user experience. Utility Model Content

[0003] In order to improve the problem that liquid foundation cannot be discharged in time when pressed, and the discharge is uneven; when shaken, placed sideways or inverted, the liquid foundation leaks, affecting the user experience, the present application provides a composite membrane cloth for air cushion that can quickly discharge the liquid when pressed and is leak-proof.

[0004] The present application provides a composite membrane cloth for air cushions that is quick to discharge and leak-proof, using the following technical solutions:

[0005] A composite membrane cloth for air cushions that allows for quick discharge and prevents leakage when pressed, comprising a composite of a knitted cloth and a PDMS membrane. The knitted cloth, serving as a base layer, is elastic and contains multiple coils, enabling quick and uniform release of liquid foundation. The PDMS membrane is provided with a plurality of uniform or non-uniform cracks at recesses corresponding to adjacent coils of the knitted cloth. When the composite membrane cloth is pressed, the cracks open, allowing liquid foundation to pass quickly and evenly through the cracks and coils in sequence. When no external force is applied, the cracks close, preventing liquid foundation from leaking.

[0006] By adopting the above technical solution, the cracks opened allow the foundation liquid to be quickly and evenly discharged from the cracks when the composite film cloth is pressed; when no external force is applied, the cracks are closed to prevent the leakage of the foundation liquid, thereby preventing waste and pollution caused by the leakage of the foundation liquid.

[0007] Optionally, the knitted fabric is woven from 30-150D yarn, and its structure is one or more of rib structure, double rib structure, double reverse structure, tuck structure, furrow structure, half furrow structure, fat flower structure, rib warp plain structure, double rib warp plain structure, double warp plain structure, warp velvet structure, warp velvet plain structure, warp oblique plain structure, warp velvet chain structure, warp oblique chain structure, and spacer structure.

[0008] By adopting the above technical solution, the knitted fabric woven with a variety of blended yarns has better elasticity, and the coil holes inside allow the foundation liquid to pass through quickly and evenly.

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

[0010] By adopting the above technical solution, spandex is used as a necessary raw material for the knitted fabric yarn in the application because spandex has good elasticity, high extensibility, high elastic recovery rate, is not easy to wrinkle, and is durable and not easy to age during use, has stable chemical properties, and has high biocompatibility.

[0011] Optionally, the knitted fabric has an elastic recovery rate greater than 90%, a thickness of 0.3-1 mm, and a gram weight of 80-300 g / m2.

[0012] By adopting the above technical solution, in order to meet the user's physical sensation, the thickness and gram weight of the knitted fabric are controlled within the corresponding specific gravity to avoid the thickness and gram weight being too large or too small, which affects the leakage or discharge of the foundation liquid.

[0013] Optionally, the PDMS film has a thickness of 0.05-0.5 mm.

[0014] By adopting the above technical solution, when the PDMS membrane thickness is too small, it will cause the foundation liquid to leak; when the PDMS membrane thickness is too large, it will affect the discharge of the foundation liquid. Therefore, the designed PDMS membrane thickness is consistent with the discharge speed and uniformity of the discharge.

[0015] Optionally, adjacent coils are extended up and down and wound in an interlaced manner.

[0016] By adopting the above technical solution, the staggered winding space facilitates the uniform leakage of liquid foundation.

[0017] Optionally, the yarn knitting structural units of the knitted fabric are upper knitting loop-lower knitting loop-upper knitting loop-lower knitting loop in sequence.

[0018] By adopting the above technical solution, the staggered weaving method allows for even passage of foundation liquid after the cracks are opened, and provides a barrier effect when the cracks are closed.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] In the utility model, the knitted fabric serves as the base layer, which is elastic and contains multiple coils, and can quickly and evenly release liquid foundation; the PDMS membrane is provided with a number of uniform or uneven cracks at the recesses corresponding to the adjacent coils of the knitted fabric. When the composite membrane cloth is pressed, the cracks open, and the liquid foundation can pass through the cracks quickly and evenly; when no external force is applied, the cracks close to 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.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiments of the present application disclose a composite membrane cloth for air cushions that can be quickly discharged by pressing and is leak-proof.

[0031] Reference Figure 1 , which is composed of a knitted fabric 1 and a PDMS membrane 2, and its structure is as follows Figure 1 、 Figure 2、 Figure 3 、 Figure 4 As shown, the elastic knitted fabric 1 serves as the base layer and contains multiple coils, enabling rapid and even release of liquid foundation. Adjacent coils are wound in an interlaced pattern, extending vertically. The PDMS membrane 2 is provided with several uniform or uneven cracks 3 in the recesses corresponding to adjacent coils of the knitted fabric 1. When the composite membrane is pressed, the cracks 3 open, allowing liquid foundation to pass quickly and evenly through the cracks 3 and then the coils. When no external force is applied, the cracks 3 close, preventing liquid foundation leakage.

[0032] The knitted fabric 1 of the present invention is woven from yarn with a denier of 30-150 denier. The yarn knitting structure unit is knitted in the order of upper loop-knitted loop-knitted loop-knitted loop-knitted loop, with a staggered upper-lower weave. The yarn is made of spandex or a blend of at least 10% spandex with one or more of polyester, nylon, acrylic, modal, acetate, viscose, cupro, or cotton. The structure of the knitted fabric 1 is one or more of rib, double rib, double purl, tuck, fur braid, half fur braid, tuck, rib plain, double rib plain, double plain, warp velvet, warp velvet plain, warp diagonal plain, warp velvet chain, warp diagonal chain, or spacer weave. Spandex is used as a necessary raw material for the knitted fabric yarn of the present invention because it has good elasticity, high extensibility, high elastic recovery rate, and is not prone to wrinkling. In addition, spandex is durable, non-aging, chemically stable, and highly biocompatible. The knitted fabric 1 is formed by a plurality of loops. The knitted fabric 1 woven with spandex or spandex blended yarn has better elasticity, and the loop holes inside the knitted fabric 1 can allow liquid foundation to pass through quickly and evenly.

[0033] The knitted fabric 1 is elastic, and its elastic recovery rate is greater than 90% (industry standard FZ / T70006 knitted fabric tensile elastic recovery rate test method). The thickness of the knitted fabric 1 is 0.3-1mm, and the gram weight is 80-300g / m2. If the thickness and gram weight 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.

[0034] The PDMS membrane 2 of this application is composed of the following raw materials by weight: 8-12 parts of Dow Corning SYLGARD 184 PDMS base component and 1 part of Dow Corning SYLGARD 184 crosslinking curing agent. Polydimethylsiloxane film is non-toxic and odorless, has a low modulus, is chemically stable, and has excellent biocompatibility, making it safe for use in daily cosmetics, particularly in composite membranes for air cushions. Dimethylsiloxane film is simple and quick to prepare. In particular, it is an elastomer that can be laminated to the knitted fabric 1 without affecting the overall feel of the composite membrane, and does not require adhesive bonding.

[0035] The thickness of the PDMS membrane 2 is 0.05 to 0.5 mm. If the thickness is too thin, the foundation will easily leak; if the thickness is too thick, the cracks 3 cannot be fully opened when the composite membrane cloth is pressed, affecting the discharge speed and discharge uniformity.

[0036] The PDMS membrane 2 is provided with a number of uniform or uneven cracks 3 in the recesses corresponding to adjacent coils of the knitted fabric 1. When the composite membrane fabric is pressed, liquid foundation can pass through these cracks quickly and evenly. Without external force, the cracks 3 close, preventing liquid foundation from leaking. Even if shaken, placed sideways, or inverted, the liquid foundation is unlikely to spill, thus preventing waste and pollution caused by leakage.

[0037] The implementation principle of the composite membrane cloth for air cushions that can be quickly discharged and is leak-proof when pressed in the embodiment of the present application is as follows: a number of uniform or uneven cracks are provided in the concave parts of the PDMS membrane corresponding to the adjacent coils of the knitted cloth. When the composite membrane cloth is pressed, the cracks are in an open state, and the foundation liquid can pass through the cracks quickly and evenly, facilitating discharge; when no external force is applied, the cracks are in a closed state, preventing the leakage of the foundation liquid. When shaken, placed sideways or inverted, the cracks are in a closed state, and the foundation liquid is difficult to overflow, thereby avoiding waste and pollution caused by leakage of the foundation liquid, ensuring uniform discharge of the foundation liquid during use, and effective barrier when closed, thereby improving user experience.
