Description

Technical Field

[0001] The present application relates to the technical field of daily cosmetics, and more specifically, to a composite membrane cloth for air cushions and a preparation method thereof. Background Art

[0002] In recent years, with the rapid development of the beauty and cosmetics industry, people have increasingly higher requirements for the texture, user experience and makeup effect of cosmetics. As a new type of cosmetics product, air cushion foundation has received widespread attention and popularity due to its lightness, portability and ease of use.

[0003] The mesh air cushion product is a common air cushion foundation. It uses mesh as the storage and distribution medium of the liquid foundation. It has more foundation capacity, is not easy to breed bacteria, is more hygienic, and has the advantages of light weight, long service life, and not easy to perforate.

[0004] In order to make the liquid foundation more breathable and moisturizing after being applied to the user's face, and to allow the liquid foundation to quickly seep out when the user presses the mesh, manufacturers often use foundation with lower viscosity and mesh with larger holes to produce mesh air cushions. However, during shaking, sideways and inversion, the liquid foundation easily leaks from the mesh, causing pollution and waste. Or in order to prevent the liquid foundation from penetrating when shaking, sideways and inverted, manufacturers will use foundation with higher viscosity and mesh with smaller holes to produce mesh air cushions, which are often accompanied by problems such as failure to discharge the material in time and uneven discharge when pressed, affecting the user experience.

[0005] Therefore, it is urgent to propose a solution to solve the above technical problems. Summary of the invention

[0006] In order to prevent the liquid foundation from leaking when the mesh air cushion is shaken, placed sideways or inverted, and to evenly release the liquid foundation when pressed, the present application provides a composite membrane cloth for an air cushion and a preparation method thereof.

[0007] In the first aspect, the present application provides a composite membrane cloth for an air cushion, which adopts the following technical solution: A composite membrane cloth for an air cushion, comprising a fabric layer (1) and a microporous membrane layer (2), wherein the fabric layer (1) and the microporous membrane layer (2) are bonded and attached by hot-melt bonding; The fabric layer (1) is an elastic fabric capable of releasing liquid foundation; The microporous membrane layer (2) is provided with a plurality of irregular micropores for controlling the passage of foundation liquid by applying external force.

[0008] By adopting the above technical solution, the interior of the fabric layer has a complex mesh structure, which has a good absorption and storage effect on the liquid foundation, and the fabric layer is an elastic fabric, which can quickly undergo reversible deformation after being pressed, and as the deformation is carried out under pressure, the absorbed liquid foundation can be released evenly and quickly. The microporous membrane layer is provided with a number of irregular micropores. When not subjected to the pressure, the liquid foundation cannot leak through the micropores. At this time, even if the mesh air cushion is in the process of shaking, sideways and inverted, the liquid foundation is difficult to leak, which can avoid waste and pollution caused by the leakage of the liquid foundation; and when the microporous membrane layer is subjected to the pressure, the micropores further expand, and the liquid foundation can pass quickly and evenly through the micropores and the fabric layer in turn, and then can release the liquid foundation evenly when pressed. At the same time, the several irregular micropores on the microporous membrane layer can be used for pressing pressure from different directions, ensuring that a better liquid foundation release effect can be achieved after being pressed. In this way, during actual application, the composite membrane cloth for the air cushion can prevent the liquid foundation from leaking when the mesh air cushion is shaken, placed sideways or inverted, and can evenly release the liquid foundation when pressed, with an outstanding overall application effect.

[0009] Preferably, the fabric layer (1) is a woven fabric or a knitted fabric.

[0010] By adopting the above technical scheme, the woven fabric can maintain the shape and stability of the air cushion through its tight and stable structure, and its good air permeability helps the air cushion to stay dry and comfortable during use; the knitted fabric has good elasticity and can adapt to the movement and deformation of the body, providing better fit and comfort; and using woven fabric or knitted fabric as the fabric layer can obtain a composite membrane fabric for the air cushion with excellent and stable quality.

[0011] Preferably, the fabric layer (1) is woven from yarns with a yarn count of 30-150D.

[0012] By adopting the above technical solution, the fabric layer woven from the yarn of the above specification can form a better bonding state with the microporous membrane layer, and can be suitable for the application of composite membrane cloth for air cushions, and can stably play its role during the application process.

[0013] Preferably, the yarn of the fabric layer (1) is spandex yarn or spandex blended yarn, and the spandex blended yarn is a blend of spandex and one or more of polyester, nylon, acrylic, modal fiber, acetate fiber, viscose fiber, cupro fiber, and cotton fiber.

[0014] By adopting the above technical scheme, spandex, also known as elastic fiber or Lycra fiber, is a synthetic fiber composed of polyurethane, which has excellent elasticity and extensibility, and high elastic recovery rate and elongation at break. The elongation at break exceeds 400%, and can reach up to 800%. Even under a tensile deformation of 300%, the rebound recovery rate can still be maintained at more than 95%, showing extraordinary elastic recovery ability; at the same time, spandex has good support, good air permeability, and good biocompatibility, which makes the composite membrane cloth for air cushions have better application effect.

[0015] Preferably, the spandex content in the spandex blended yarn is at least 10%.

[0016] By adopting the above technical scheme, the spandex content is at least 10%, which can not only ensure that the fabric layer exhibits excellent high elasticity and meet the application requirements of the composite membrane cloth for air cushions, but also enable the fabric layer to have certain spandex advantages, thereby obtaining a composite membrane cloth for air cushions with better application quality.

[0017] Preferably, the elastic recovery rate of the fabric layer (1) is greater than 95%.

[0018] By adopting the above technical solution, the elastic recovery rate of the fabric layer is made greater than 95%, so that the composite membrane cloth for air cushions can exert rapid and excellent elastic deformation ability after being pressed, and can quickly make elastic recovery after being released from the pressure, so that the composite membrane cloth for air cushions can exert better application effects.

[0019] Preferably, the fabric layer (1) has a thickness of 0.3-1 mm and a gram weight of 80-300 g / m 2 .

[0020] By adopting the above technical solution, the fabric layer of the above specifications can meet the practical application requirements of the composite membrane cloth for air cushions, and after being compounded with the microporous membrane layer, the composite membrane cloth for air cushions has a stable and better application effect.

[0021] Preferably, the microporous membrane layer (2) is a SEBS membrane, and the thickness of the SEBS membrane is 0.1-1 mm.

[0022] By adopting the above technical solution, the SEBS membrane has excellent elasticity and recovery, and excellent weather resistance, heat resistance, chemical resistance and air permeability, which can make the composite membrane cloth for air cushion more durable, softer and more comfortable. As for the thickness of the microporous membrane layer, if the thickness of the microporous membrane layer is lower than the above range, the composite membrane cloth for air cushion is prone to leakage of foundation liquid during shaking, sideways and inverted; if the thickness of the microporous membrane layer is higher than the above range, the composite membrane cloth for air cushion will cause the foundation liquid to be discharged slowly when it is pressed; therefore, the microporous membrane layer of the above thickness can play an excellent and stable corresponding effect during the application process, thereby ensuring that the composite membrane cloth for air cushion has excellent application quality.

[0023] In a second aspect, the present application provides a method for preparing a composite membrane cloth for an air cushion, which adopts the following technical solution: A method for preparing a composite membrane cloth for an air cushion comprises the following steps: S1, ironing and cleaning the surface of the raw materials used to prepare the fabric layer (1) for later use; cutting the raw materials used to prepare the microporous membrane layer (2) for later use; S2, bringing the adhesive surface of the raw material used to prepare the microporous membrane layer (2) in step S1 into contact with the reverse surface of the raw material used to prepare the fabric layer (1), and laying the two neatly; S3, performing heat-pressing and fusing treatment on the finished product obtained in step S2, and cooling after completion, thereby obtaining a composite membrane cloth for an air cushion.

[0024] By adopting the above technical scheme, the above preparation method is simple to operate and convenient for quality control during the process. It is not only suitable for large-scale industrial production of composite membrane cloth for air cushions, but also can obtain composite membrane cloth for air cushions with excellent quality.

[0025] Preferably, in the hot pressing fusion treatment of step S3, the hot pressing pressure is 0.2-0.5 MPa, and the fusion method is pure heating fusion or high frequency fusion; The pure heating fusion temperature is 160-190°C, and the heating time is 15-60s; The temperature of the high frequency fusion is 110-140° C., and the heating time is 5-30 seconds.

[0026] By adopting the above technical solutions, pure heating fusion melts the material surface through high temperature, thereby achieving seamless connection; high-frequency fusion uses high-frequency electromagnetic fields to generate friction heat in the internal molecules of the plastic material, thereby achieving heating, welding and heat sealing of the material, which has the characteristics of fast heating speed, high welding strength and high production efficiency; and the selection of the above-mentioned hot pressure fusion, as well as the control of temperature and time, can ensure that the obtained composite membrane cloth for air cushions has excellent and stable application quality.

[0027] In summary, this application has the following beneficial effects: The present application prepares a composite membrane cloth for an air cushion by hot-melt bonding and laminating a fabric layer and a microporous membrane layer, and utilizes a plurality of irregular micropores on the microporous membrane layer for controlling the passage of liquid foundation by applying external force. 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. Therefore, in the actual application of the composite membrane cloth for an air cushion, it can not only prevent the liquid foundation from leaking when the mesh air cushion is shaken, placed sideways or inverted, but also can evenly release the liquid foundation when pressed.

[0053] Performance testing Test sample: The composite membrane cloth for air cushion obtained in Example 1-19 was used as test sample 1-19.

[0054] Test method: The commercially available Lancome Absolu Essence Liquid Foundation was used as the test liquid foundation, which was combined with test samples 1-19 respectively to obtain 19 types of air cushion foundation products.

[0055] (1) Shaking, sideways and inverted test: Press the composite membrane cloth for the air cushion to absorb the liquid foundation and then shake, sideways and invert it. The shaking amplitude is 15 degrees and the sideways angle is 45 degrees. Observe whether there is any leakage of liquid foundation.

The specific operation can be to invite 2 volunteers with dry skin and oily skin to use test samples 1-19 in turn, wash their faces with facial cleanser and water before use to ensure that the face is clean, and carefully observe the surface of the skin after use to see if there is obvious color difference or mottled phenomenon. If the color of the skin surface is uniform, without obvious color blocks or color differences, then it can be considered that the liquid foundation is distributed relatively evenly.

[0057] Table 1 Application test results of experimental samples 1-19 Combining Examples 1-2 and Table 1, it can be seen that the use of woven fabrics or knitted fabrics as fabric layers can obtain composite membrane cloths for air cushions with excellent and stable quality. Combining Examples 1 and 3-4 and Table 1, it can be seen that the fabric layer is woven from yarns with a yarn count of 30-150D, which can be used for the application of composite membrane cloths for air cushions and can stably play its role during the application process. Combining Examples 1 and 5-6 and Table 1, it can be seen that the yarn of the fabric layer is spandex yarn or spandex blended yarn, and only composite membrane cloths for air cushions with excellent application quality can be obtained. Combining Example 7 and Table 1, it can be seen that in the application of spandex blended yarns, when the spandex content is less than 10%, it is found that there will be slight color blocks and color differences in the uniformity test of the liquid foundation, indicating that the spandex content is at least 10%, which can ensure that the fabric layer exhibits excellent high elasticity and meets the application requirements of the composite membrane cloth for air cushions.

[0058] Combining Example 1 and Example 8 with Table 1, it can be seen that when the elastic recovery rate of the fabric layer 1 is greater than 95%, the composite membrane cloth for the air cushion can exert a relatively stable effect during the pressing process. Combining Examples 9-10 with Table 1, it can be seen that the thickness of the fabric layer is 0.3-1mm and the gram weight is 80-300g / m 2 When it is compounded with the microporous membrane layer, the quality of the composite membrane cloth for air cushion obtained is better.

[0059] Combining Example 1 and Example 11-12 with Table 1, it can be seen that when the microporous membrane layer is a SEBS membrane and the thickness of the SEBS membrane is 0.1-1 mm, the microporous membrane layer can exert excellent and stable corresponding effects during the application process, so that the composite membrane cloth for air cushion is not prone to leakage of liquid foundation during shaking, sideways and inversion. Combining Example 13-14 with Table 1, it can be seen that when the thickness of the microporous membrane layer is lower or higher than the above range, the obtained composite membrane cloth for air cushion will leak liquid foundation when shaken, sideways and inverted after the above test, and there will be obvious color blocks and color differences after the liquid foundation is applied.

[0060] It can be seen from Example 1 and Examples 15-19 and Table 1 that in the hot pressing fusion treatment, the hot pressing pressure is controlled to be 0.2-0.5MPa, the fusion method is pure heating fusion or high frequency fusion, and the preferred temperature for pure heating fusion is 160-190°C, the heating time is 15-60s, and the temperature for high frequency fusion is 110-140°C, the heating time is 5-30s, all of which can ensure that the obtained composite membrane cloth for air cushions has excellent application quality.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
