Description

Technical Field

[0001] This application relates to the field of membrane fabric technology, and in particular to a granular facial mask fabric and the same. Background Technology

[0002] The mask sheet is the core component of sheet masks, mainly serving as a carrier for the essence. It promotes the penetration of active ingredients into the stratum corneum of the skin through physical adhesion. Its material and structure directly affect the absorption efficiency of the essence, the comfort of use, and the skin care effect.

[0003] Current mask technology is evolving from "passive liquid carrier" to "active empowerment," leading to an increasing number of functional masks. These masks target specific skin concerns, such as moisturizing, anti-aging, whitening, and repair, through combinations of specific active ingredients and carrier technologies. To achieve specific effects, current methods involve using the mask's mesh structure to adsorb and lock in active ingredients, or using freeze-drying technology to directly solidify high-concentration active ingredients into the fiber pores of the mask through low-temperature vacuum dehydration. Alternatively, the mask can be folded and soaked in essence, utilizing the hydrophilicity and capillary action of the fibers to adsorb the ingredients. While these methods can carry certain functional ingredients, they all require mixing the active ingredients with other liquids to form a purified solution before they can penetrate, soak, or adhere to the fiber pores. Furthermore, the carrying capacity is limited, and the active ingredients cannot maintain their original properties well, easily being diluted or having their efficacy reduced by other ingredients or liquids, thus failing to achieve the best results during use. Utility Model Content

[0004] Therefore, the purpose of this invention is to overcome the shortcomings of existing membrane fabrics that rely solely on fiber pores to attach active ingredients, resulting in insufficient high-concentration adhesion and thus inadequate efficacy. This invention provides a granular mask fabric and the mask thereof. This invention establishes a separate carrier layer for the active ingredient and a liquid carrier layer, preventing dilution of the active ingredient by other solvents and ensuring its concentration and efficacy are not affected, thereby improving the concentration of active ingredients and the overall effect.

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

[0006] A granular facial mask fabric includes a base layer, a gel layer composited with the base layer, and a porous granular layer attached to the surface of the gel layer; the porous granular layer is formed by a plurality of uniformly distributed porous particles.

[0007] This invention uses a base layer as the main structural support, upon which a gel layer is composited. The gel layer can lock in moisture or other liquids, and its surface has a certain adhesive effect, allowing porous particles to adhere to it. Because the porous particles have a larger specific surface area, they can act as carriers for the active ingredients independently, allowing the active ingredients and other solvent liquids to be carried separately within the mask fabric. This allows for the carrying of more effective ingredients without diluting them or affecting their concentration and efficacy. Other solvent liquids are carried by the gel layer, creating a separate carrier layer for the active ingredients and a liquid carrier layer, thus improving the concentration of active ingredients and the overall effect of use.

[0008] It should be noted that after the active ingredients are impregnated in the porous particle layer, they are dehydrated using freeze-drying technology at low temperature and vacuum, which solidifies the high concentration of active ingredients in the porous particles, thus achieving the adhesion of the active ingredients. Then, the porous particle layer is evenly sprayed onto the surface of the gel layer, and the active ingredients are attached to the gel layer by the surface adhesion force of the gel layer, thus achieving the layered carrying of the active ingredients.

[0009] Furthermore, each of the porous particles is in the form of a short rod, and / or a sphere, and / or a powder, and each of the porous particles has a plurality of irregularly distributed pores.

[0010] Particles with porous structures have a larger specific surface area, enabling them to adsorb and carry more functional molecules, thus achieving a higher concentration of active ingredients.

[0011] Furthermore, the particle size of each porous particle is 200nm~800nm. The particle size of the active ingredients is mostly below 50nm, because the intercellular space of skin cells is generally 100-120nm. According to the penetration requirements, the particle size of the nanoparticles of the active ingredients is mostly controlled within ≤50nm. Through continuous experimentation, the particle size of the porous particles used to carry the active ingredients in this invention is controlled between 200nm and 800nm, which can have a good carrying capacity, and at the same time, it has better adhesion and a better user experience when applied to the skin.

[0012] Furthermore, the specific surface area of ​​each of the porous particles is 1000 m² / g to 2200 m² / g.

[0013] Furthermore, the distribution density of the porous particles is 50% to 80% of the gel layer.

[0014] Furthermore, the porous particles are microcrystalline cellulose particles, bamboo fiber particles, or coconut shell fiber particles.

[0015] It should be noted that microcrystalline cellulose particles can be obtained by hydrolyzing natural cellulose with dilute acid to form short rods or powder, and the porosity can be controlled by the degree of hydrolysis; bamboo fiber particles or coconut shell fiber particles can be carbonized to generate porous carbon materials with a natural pore structure and a very high specific surface area.

[0016] Furthermore, the gel layer is a hydrophilic polymer gel layer.

[0017] It should be noted that the hydrophilic polymer gel layer can be composed of hydrophilic polymer gels, such as carbomer, polyvinyl alcohol (PVA), and hyaluronic acid cross-linked polymers. Through polymerization, a three-dimensional network structure is formed, which can absorb and lock in water up to tens of times its own weight. When made into a face mask, it can serve as the main moisturizing layer to lock in moisture and release moisture during use. At the same time, the surface of the gel layer has a certain degree of adhesion, which can adhere to porous particles.

[0018] Furthermore, the base layer is a non-woven fabric layer, a silk layer, a fruit fiber layer, a bio-fiber layer, a Tencel plant fiber layer, a viscose fiber layer, or a microfiber layer.

[0019] Furthermore, the side of the base layer facing away from the gel layer is also coated with a hydrophobic film.

[0020] It should be noted that hydrophobic films can be formed by cross-linking polyvinyl alcohol (PVA) and polyacrylic acid polymers to create a three-dimensional network film, which physically blocks moisture from escaping while also being breathable to prevent acne breakouts.

[0021] This invention also provides a face mask, comprising the granular face mask fabric as described above, wherein the porous granular layer adsorbs active ingredients.

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

[0023] This invention uses a base layer as the main structural support, upon which a gel layer is composited. The gel layer can lock in moisture or other liquids, and its surface has a certain adhesive effect, allowing porous particles to adhere to it. Because the porous particles have a larger specific surface area, they can act as carriers for the active ingredients independently, allowing the active ingredients and other solvent liquids to be carried separately within the mask fabric. This allows for the carrying of more effective ingredients without diluting them or affecting their concentration and efficacy. Other solvent liquids are carried by the gel layer, creating a separate carrier layer for the active ingredients and a liquid carrier layer, thus improving the concentration of active ingredients and the overall effect of use.

[0034] Example 1

[0035] like Figure 1 and Figure 2As shown, a granular mask fabric includes a base layer 1, a gel layer 2 composite with the base layer 1, and a porous granular layer 3 attached to the surface of the gel layer 2; the porous granular layer 3 is formed by a plurality of uniformly distributed porous particles 31.

[0036] like Figure 3 and Figure 4 As shown, each porous particle 31 is a short rod-shaped and spherical porous particle, and each porous particle 31 has a number of irregular pores distributed on it.

[0037] Particles with porous structures have a larger specific surface area, enabling them to adsorb and carry more functional molecules, thus achieving a higher concentration of active ingredients.

[0038] In this embodiment, the particle size of each porous particle 31 is 200nm~800nm. The particle size of the active ingredients is mostly below 50nm, because the intercellular space of skin cells is generally 100-120nm. According to the penetration requirements, the particle size of the nanoparticles of the active ingredients is mostly controlled within ≤50nm. Through continuous experimentation, the particle size of the porous particles 31 used to carry the active ingredients in this embodiment is controlled between 200nm and 800nm, which can have a good carrying capacity, and at the same time, it has better adhesion and a better user experience when applied to the skin.

[0039] In this embodiment, the specific surface area of ​​each porous particle 31 is 1000m² / g to 2200m² / g.

[0040] In this embodiment, the distribution density of porous particles 31 is 50% to 80% of the gel layer.

[0041] In this embodiment, the porous particles 31 are microcrystalline cellulose particles.

[0042] In this embodiment, microcrystalline cellulose particles can be obtained by hydrolyzing natural cellulose with dilute acid to form short rod-shaped porous particles 31, and the porosity can be controlled by the degree of hydrolysis.

[0043] In this embodiment, gel layer 2 is a hydrophilic polymer gel layer.

[0044] It should be noted that the hydrophilic polymer gel layer can be composed of hydrophilic polymer gel; in this embodiment, the hydrophilic polymer gel layer is a hyaluronic acid cross-linked polymer, which forms a three-dimensional network structure through polymerization, and can absorb and lock in water up to tens of times its own weight. When made into a face mask, it can serve as the main moisturizing layer to lock in moisture and release moisture when used. At the same time, the surface of the gel layer 2 has a certain degree of adhesion and can adhere to porous particles 31.

[0045] In this embodiment, the base layer 1 is a non-woven fabric layer.

[0046] The advantage of this embodiment is that the base layer 1 serves as the main structural support, and a gel layer 2 is laminated on it. The gel layer 2 can lock in moisture or other liquids. At the same time, the surface of the gel layer 2 has a certain adhesive effect, allowing porous particles 31 to adhere to the surface of the gel layer 2. Since the porous particles 31 have a larger specific surface area, they can act as carriers of active ingredients on their own, allowing the active ingredients and other solvent liquids to be carried separately in the mask sheet. This allows for the carrying of more effective ingredients, and the active ingredients will not be diluted by other solvent liquids, affecting their concentration and efficacy. Other solvent liquids are carried by the gel layer 2, forming a mode where the active ingredient carrier layer and the liquid carrier layer are separated, improving the carrying concentration of active ingredients and the effect of use.

[0047] Example 2

[0048] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0049] In this embodiment, the porous particles 31 are coconut shell fiber particles.

[0050] In this embodiment, coconut shell fiber particles can be carbonized to generate porous carbon materials with a natural pore structure and a very high specific surface area.

[0051] The advantage of this embodiment is that the base layer 1 serves as the main structural support, and a gel layer 2 is laminated on it. The gel layer 2 can lock in moisture or other liquids. At the same time, the surface of the gel layer 2 has a certain adhesive effect, allowing porous particles 31 to adhere to the surface of the gel layer 2. Since the porous particles 31 have a larger specific surface area, they can act as carriers of active ingredients on their own, allowing the active ingredients and other solvent liquids to be carried separately in the mask sheet. This allows for the carrying of more effective ingredients, and the active ingredients will not be diluted by other solvent liquids, affecting their concentration and efficacy. Other solvent liquids are carried by the gel layer 2, forming a mode where the active ingredient carrier layer and the liquid carrier layer are separated, improving the carrying concentration of active ingredients and the effect of use.

[0052] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0053] Example 3

[0054] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0055] like Figure 5 As shown, the side of the base layer 1 facing away from the gel layer 2 is also coated with a hydrophobic film 4.

[0056] In this embodiment, the hydrophobic membrane 4 is formed by cross-linking polyvinyl alcohol (PVA) polymer to form a three-dimensional network membrane, which physically blocks the loss of moisture while being breathable to avoid acne.

[0057] The advantage of this embodiment is that the base layer 1 serves as the main structural support, and a gel layer 2 is laminated on it. The gel layer 2 can lock in moisture or other liquids. At the same time, the surface of the gel layer 2 has a certain adhesive effect, allowing porous particles 31 to adhere to the surface of the gel layer 2. Since the porous particles 31 have a larger specific surface area, they can act as carriers of active ingredients on their own, allowing the active ingredients and other solvent liquids to be carried separately in the mask sheet. This allows for the carrying of more effective ingredients, and the active ingredients will not be diluted by other solvent liquids, affecting their concentration and efficacy. Other solvent liquids are carried by the gel layer 2, forming a mode where the active ingredient carrier layer and the liquid carrier layer are separated, improving the carrying concentration of active ingredients and the effect of use.

[0058] Example 4

[0059] like Figure 6 As shown, this embodiment also provides a face mask, including a granular face mask cloth as described in the above embodiment, wherein the porous granular layer 3 adsorbs effective ingredients.

[0060] In this embodiment, the active ingredients are impregnated in the porous particle layer 3 and then dehydrated under low temperature vacuum using freeze-drying technology to solidify the high concentration of active ingredients in the porous particles 31, thereby achieving the adhesion of the active ingredients. Then, the porous particle layer 3 is evenly sprayed onto the surface of the gel layer 2 by uniform spraying, and the active ingredients are adhered to the gel layer 2 by the surface adhesion force of the gel layer 2, thereby achieving the layered carrying of the active ingredients.

[0061] In this embodiment, the mask has openings for eyes, nose and mouth, and several symmetrical cuts are made around the perimeter of the mask.

[0062] The advantage of this embodiment is that the base layer 1 serves as the main structural support, and a gel layer 2 is laminated on it. The gel layer 2 can lock in moisture or other liquids. At the same time, the surface of the gel layer 2 has a certain adhesive effect, allowing porous particles 31 to adhere to the surface of the gel layer 2. Since the porous particles 31 have a larger specific surface area, they can act as carriers of active ingredients on their own, allowing the active ingredients and other solvent liquids to be carried separately in the mask sheet. This allows for the carrying of more effective ingredients, and the active ingredients will not be diluted by other solvent liquids, affecting their concentration and efficacy. Other solvent liquids are carried by the gel layer 2, forming a mode where the active ingredient carrier layer and the liquid carrier layer are separated, improving the carrying concentration of active ingredients and the effect of use.
