Description

Technical Field

[0001] This invention belongs to the field of textile materials technology, specifically relating to an algae fiber membrane and its preparation method. Background Technology

[0002] Facial masks create a sealed environment by adhering to the skin with a sheet or cream, preventing air from contacting the skin and allowing the essence to penetrate the stratum corneum more quickly and deeply. This precisely replenishes moisture and nutrients, improving skin dryness, dullness, and roughness in a short time. At the same time, the application process can soothe the skin and relax the mind and body, becoming a ritualistic part of daily skincare. They are tailored to the specific needs of different skin types and are an important means of quickly revitalizing the skin and consolidating the effects of skincare, making skincare more targeted and efficient.

[0003] In existing technologies, most facial mask sheets use a single material combination, relying mainly on pure chemical fibers or single natural fibers, without combining the advantages of different materials. This results in traditional mask sheets having low liquid absorption capacity, easy loss of essence, short moisturizing duration, and chemical residues or improper processes that can easily cause discomfort to sensitive skin. They are unable to meet the needs of deep and long-lasting hydration and gentle skin care. Therefore, there is a need for an algae fiber mask sheet and its preparation method. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and rationally designed seaweed fiber membrane and its preparation method in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A seaweed fiber membrane fabric and its preparation method are disclosed. The membrane fabric is made of 25% seaweed extract and 75% plant fiber. The seaweed extract contains alginic acid as an active ingredient, and the plant fiber is lyocell fiber. The membrane fabric has a cross-linked mesh structure, is white, and has a single-layer sheet structure with breathability.

[0006] As a further optimization of the present invention, the membrane cloth forms a crystal clear gel-like gel after being filled with liquid, and the membrane cloth fibers are evenly arranged and the pores are used for carrying and releasing the essence.

[0007] As a further optimization of the present invention, the edge of the membrane fabric has a regular cut structure with no loose fibers exposed, and the thickness of the membrane fabric is uniform with a deviation of no more than ±0.02mm.

[0008] As a further optimization of the present invention, the method for preparing the seaweed fiber membrane includes the following steps: S1. Mix seaweed extract and plant fiber in a certain proportion, and form a uniform fiber web after opening and combing. S2. The fiber web is formed using a cross-laying process and reinforced by high-pressure water jet puncture to form a cross-textured structure. S3. Cut the formed fabric and remove irregular parts at the edges to obtain the initial membrane fabric; S4. Clean the initial membrane cloth to remove processing residues; S5. Dry the cleaned membrane at 50-60℃ for 15-20 minutes. S6. Inspect the dried membrane fabric and select the finished membrane fabric that is free of damage and stains.

[0009] As a further optimization of the present invention, the pressure of the medium-high pressure water flow in S2 is 0.3 to 0.5 MPa, and the angle of the cross-laying net is 90°.

[0010] As a further optimization of the present invention, in step S4, deionized water is used for cleaning, the cleaning temperature is 25-30℃, and the membrane cloth is left to soak for 5-8 minutes during the cleaning process.

[0011] As a further optimization of the present invention, the drying process in step S5 adopts a hot air circulation method, and the membrane cloth is laid flat during drying without tension or pulling.

[0012] As a further optimization of the present invention, the seaweed fiber membrane mask is formed by impregnating a skin care essence with the seaweed fiber membrane as the base fabric or the seaweed fiber membrane obtained by the seaweed fiber membrane preparation method described above.

[0013] The beneficial effects of this invention are as follows: 1. This invention utilizes the natural moisturizing ingredients such as polysaccharides and fucoidan from seaweed extract, and the skin-friendly, breathable, and water-locking properties of lyocell fiber. The two are cross-laid at 90° and punctured by a high-pressure water flow of 0.3-0.5MPa to form a well-developed cross-textured structure with a liquid absorption rate of up to 24 times. After being filled with liquid, it forms a crystal clear gel-like gel that can efficiently carry and release moisturizing essence for a long time. It can increase skin moisture within 15 minutes of application, and the moisture content increases by 50% after 1 hour of moisturizing test, achieving deep and long-lasting hydration.

[0014] 2. The core materials of this invention are natural seaweed extract and lyocell fiber, both of which are gentle and skin-friendly materials with no added chemical irritants. The seaweed extract contains natural alginic acid active ingredients, and the lyocell fiber has both environmental and skin-friendly properties. The combination of the two avoids the risk of irritation from the source. Combined with deionized water low-temperature washing and tension-free hot air drying process, the purity of the materials is further guaranteed, making it suitable for various skin types such as sensitive skin and post-operative skin.

[0017] Example 1: A seaweed fiber mask sheet and its preparation method. The mask sheet is made of 25% seaweed extract and 75% plant fiber, combining the moisturizing and repairing effects of seaweed extract with the skin-friendly properties of plant fiber. It is suitable for various skin types, including sensitive skin and post-operative skin, achieving long-lasting hydration, anti-oxidation, and skin barrier repair. The seaweed extract contains alginic acid, which provides moisturizing, hydrating, soothing, and repairing effects, enhancing the mask sheet's nourishing power on the skin. The plant fiber is lyocell fiber, which improves the softness and skin-friendliness of the mask sheet, ensuring a delicate feel during use. The mask sheet has a cross-linked mesh structure, which enhances the essence carrying capacity and improves the stability of the application, preventing bubbles and slippage. The mask sheet is white, avoiding the risk of skin irritation from added pigments, meeting the needs of safe skincare, and appealing to a wide range of aesthetic preferences. The mask sheet has a single-layer sheet structure and is breathable. After being filled with essence, it forms a crystal-clear gel-like substance. This crystal-clear gel-like substance enhances the adhesion between the mask sheet and the skin, locking in the essence and prolonging the skin's nourishing time. The mask sheet fibers are evenly arranged, and the pores are designed for the collection and release of the essence. The edges of the mask sheet have a regular cutting structure, which prevents loose fibers from falling off and irritating the skin, ensuring safety during use. There are no loose fibers exposed, and the mask sheet has a uniform thickness, ensuring even distribution of essence across the entire face, preventing localized dryness or essence buildup, and making the skincare effect more stable and consistent, with a deviation of no more than ±0.02mm.

[0020] Example 3: Seaweed fiber membrane mask. The seaweed fiber membrane mask uses seaweed fiber membrane as the base fabric. A seaweed fiber membrane fabric prepared by the method thereof is used as the base fabric, impregnated with skincare essence to form the mask. The mask weighs 30g. The mask does not contain fluorescent substances, cellulose-based additives, or softeners. The base fabric is cut according to the facial contours and has perforated structures for the eyes, nose, and mouth. The perforated edges are pre-reinforced to prevent curling or fraying during application. The skincare essence uses deionized water as a base and adds moisturizing ingredients such as sodium hyaluronate and glycerin. No substances conflicting with the base fabric components are added. The essence is adapted to the load-bearing and release characteristics of the base fabric. During production, the seaweed fiber membrane fabric is first... The base fabric is placed in a sterile environment and sterilized with ultraviolet light for 30 minutes. Then, the pre-treated base fabric is immersed in skin care essence at a temperature of 30℃ for 20 minutes to ensure that the base fabric fully absorbs the essence, with the amount of essence absorbed reaching more than 24 times its own weight. After immersion, the base fabric is removed and centrifuged to remove excess essence from the surface at a speed of 1500 rpm for 30 seconds. Finally, the base fabric containing the essence is placed flat in an aluminum foil packaging bag and heat-sealed at a temperature of 120℃, a pressure of 0.5 MPa, and a sealing width of 5 mm. After sealing, the mask production is complete.
