Description

Technical Field

[0001] This invention relates to the field of facial mask fabric technology, and more particularly to a temperature-sensitive facial mask fabric. Background Technology

[0002] Facial mask sheets are a common carrier of facial mask essence, typically made of non-woven fabric. Currently, facial mask sheets are used in conjunction with facial mask essence; the sheet absorbs the essence before being applied to the skin to nourish, moisturize, and brighten the skin. However, once applied to the face, the mask sheet's temperature gradually rises due to body heat. As the temperature increases, the essence within the mask evaporates, leading to a decrease in the mask's effectiveness. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a temperature-sensitive mask sheet that can reduce the evaporation of essence, provide long-lasting moisturizing, and lift and tighten the skin.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A temperature-sensitive facial mask fabric includes a main fiber layer, the lower surface of which has a plurality of first cavities arranged in an array, the first cavities being filled with a water-absorbing fiber layer, the upper surface of which has an isolation layer, the lower surface of which has a flow-guiding fiber layer, and the lower surface of which has an outer fiber layer for contact with the skin; the main fiber layer is made of the following fiber mixture in parts by weight: 3-5 parts of high-strength fiber, 2-4 parts of high-shrinkage polyester fiber, 1-3 parts of tea fiber, and 1-2 parts of acetate fiber; the water-absorbing fiber layer is made of the following fiber mixture in parts by weight: 2-4 parts of bamboo pulp fiber and 1-2 parts of viscose fiber.

[0005] This type of mask sheet uses a four-layer composite structure: an isolation layer, a main fiber layer, a diversion layer, and an outer fiber layer. The mask sheet is directional during use, meaning the outer fiber layer contacts the skin. After the essence enters the mask sheet, it is absorbed by the entire sheet. The absorbent fiber layer in the first concave cavity contains bamboo pulp fiber, which has a higher absorbency than the main fiber layer, thus most of the essence is absorbed and stored in this layer. The main fiber layer contains high-strength fibers with strong tensile strength and acetate fibers with excellent elasticity. The combination of these two allows the mask sheet to be stretched without easily breaking or tearing, while also preventing it from swelling and deforming due to water absorption. The tea fiber has good antibacterial properties, reducing bacterial growth during use. This method is more hygienic, as the isolation layer can reduce the evaporation of the essence to some extent. As the mask is left on for longer, the essence will continue to evaporate, and the mask (essence) will absorb heat and rise in temperature. High-shrinkage polyester fibers have the characteristic of shrinking as the temperature rises. The main fiber layer has a high content of high-shrinkage polyester fibers. When the temperature of the mask gradually rises, the main fiber layer will gradually shrink and become tighter. Firstly, this reduces the pores in the main fiber layer and the isolation layer, weakening the evaporation of the essence. Secondly, it squeezes the water-absorbing fiber layer in the first concave cavity, thereby ensuring that the side facing the skin remains moist. Thirdly, this shrinkage trend has a lifting effect on the skin surface, making the skin firmer.

[0006] Preferably, the first cavity is a rectangular cavity, and a drainage hole is provided at the apex corner of the adjacent first cavity on the main fiber layer. The drainage hole penetrates the main fiber layer, and the lower surface of the main fiber layer is provided with a plurality of drainage grooves for connecting the drainage hole and the first cavity. The drainage hole and drainage grooves allow the essence to quickly enter the absorbent fiber layer and be absorbed when the mask sheet is in use. When the mask sheet temperature rises, the main fiber layer gradually contracts, causing the drainage hole and drainage grooves to shrink, thereby reducing the evaporation efficiency of the essence.

[0007] Preferably, the upper surface of the main fiber layer has a plurality of second concave cavities arranged in an array corresponding to the drainage holes. The upper end of the drainage hole communicates with the bottom surface of the second concave cavity. The second concave cavity is filled with an adsorption layer, which seals the upper end of the drainage hole. The adsorption layer filling the second concave cavity has strong adsorption properties, which can adsorb impurities in the essence (impurities on the skin surface enter the essence). On the other hand, it seals the drainage hole, reducing the evaporation efficiency of the essence.

[0008] Preferably, the adsorption layer is prepared by mixing fibers in the following proportions by weight: 2-4 parts bamboo charcoal fiber and 1-2 parts activated carbon fiber. Both bamboo charcoal fiber and activated carbon fiber have good adsorption properties and are harmless to the skin.

[0009] Preferably, the absorbent fiber layer is provided with a plurality of flow-through holes. The flow-through holes allow the essence in the absorbent fiber layer to maintain better fluidity with the skin surface.

[0010] Preferably, the flow-guiding fiber layer is made by mixing the following fibers in parts by weight: 3-5 parts viscose fiber and 1-2 parts lotus leaf fiber. Lotus leaf fiber is a fiber prepared from lotus leaves, which are a traditional Chinese medicine containing abundant vitamins and possessing heat-clearing and detoxifying effects.

[0011] Preferably, the outer fiber layer is made of the following fiber mixture in parts by weight: 2-4 parts viscose fiber and 1-2 parts seaweed carbon fiber. The outer fiber layer, which comes into contact with human skin, is primarily composed of viscose fiber for greater softness, supplemented by seaweed carbon fiber. Seaweed carbon fiber has far-infrared properties, especially at 35℃ (close to human body temperature), where its far-infrared emissivity reaches up to 90%. This effectively promotes the dilation of microvessels in the skin, improves blood circulation and cell activity. Combined with the essence, this allows skin cells to better absorb the essence and remove impurities.

[0012] Preferably, the lower surface of the outer fiber layer has a plurality of third cavities arranged in a regular hexagonal array, the depth of which is 0.15-0.35 mm. The third cavities can increase the surface area of ​​the outer fiber layer, thereby facilitating the interaction between the essence and skin cells.

[0013] Preferably, the isolation layer is configured as a meltblown layer, and the polymer melt in the meltblown die is composed of the following materials mixed in parts by weight: 3-5 parts polypropylene fiber and 1-3 parts ES adhesive fiber; the melt flow index of the polymer melt is 120-135 g / 10 min, the temperature of the meltblown die is 190-195℃, the air jet angle in the meltblown die is 30-42°, the pressure of the hot air flow in the meltblown die is 0.09-0.15 MPa, and the polymer melt extrusion rate is 0.3-0.6 g / hole / min. The meltblown layer is very dense, thus preventing the evaporation of the essence. At the same time, during the meltblown process on the surface of the main fiber layer, the high temperature of the meltblown process melts some of the high-strength fibers (the melting point of high-strength fibers is close to the meltblown temperature) within the main fiber layer, thereby forming a molten layer between the main fiber layer and the isolation layer, further preventing the evaporation of the essence. Acetate fibers are added to the main fiber layer. On the one hand, the acetate fibers increase the elasticity of the main fiber layer, and on the other hand, the acetate fibers have a very high melting point (290-300℃), so they will not melt during the meltblown process, thus ensuring that the molten layer has a certain porosity to maintain the breathability of the entire mask fabric.

[0014] Preferably, the main fiber layer, the flow guiding layer, and the outer fiber layer are composited by hot rolling.

[0015] The present invention has the following beneficial effects: (1) It can reduce the evaporation of essence and keep the mask moisturizing the skin for a long time; (2) The mask has antibacterial and bacteriostatic effects during use; (3) As the temperature of the mask cloth increases, the main fiber layer contracts, thereby producing a lifting effect on the skin, making the skin firmer; (4) The mask cloth has good adsorption properties and can adsorb impurities that enter the essence; (5) The seaweed carbon fiber of the outer fiber layer has far-infrared effect, which can promote the dilation of microvessels in the skin, promote blood circulation and cell activity when the mask cloth is used. Combined with the essence, the skin cells can better absorb the essence and remove impurities. Attached Figure Description

[0033] In some embodiments, the fiber components in each fiber layer are proportioned as follows: The main fiber layer 1 is made of the following fiber mixture in parts by weight: 5 parts high-strength fiber, 2 parts high-shrinkage polyester fiber, 3 parts tea fiber, and 2 parts acetate fiber; the absorbent fiber layer is made of the following fiber mixture in parts by weight: 4 parts bamboo pulp fiber and 1 part viscose fiber; the adsorption layer is made of the following fiber mixture in parts by weight: 4 parts bamboo charcoal fiber and 2 parts activated carbon fiber; the flow guiding fiber layer is made of the following fiber mixture in parts by weight: 5 parts viscose fiber and 1 part lotus leaf fiber; the outer fiber layer is made of the following fiber mixture in parts by weight: 4 parts viscose fiber and 1 part seaweed carbon fiber.

[0035] This type of mask sheet cleverly combines the structure and raw materials of each fiber layer to enhance the mask sheet's water absorption, long-lasting moisturizing, and antibacterial effects, with the two complementing each other.

[0036] The main fiber layer has a first cavity and a second cavity. The first cavity is filled with a water-absorbing fiber layer 2, and the second cavity is filled with an adsorbent fiber layer. This gives the main fiber layer excellent water absorption and moisturizing properties, and it can also adsorb impurities. The strong fibers in the main fiber layer enhance the overall tensile strength and prevent the mask sheet from deforming. The acetate fibers maintain elasticity (and have high-temperature resistance, which provides protection for the subsequent preparation of the meltblown isolation layer). The tea fiber has antibacterial and bacteriostatic effects. The high-shrinkage polyester fiber has the characteristic of shrinking with increasing temperature. When the mask sheet is applied to the skin, it absorbs heat from the skin and heats up, causing the mask sheet to gradually shrink. Firstly, this reduces the pores of the entire mask sheet, and the drainage holes and drainage channels shrink, reducing the evaporation of the essence. Secondly, the shrinkage of the mask sheet squeezes the water-absorbing fiber layer in the first cavity, ensuring that the side facing the skin remains moist. Thirdly, this shrinkage trend lifts the skin surface, making the skin firmer.

[0037] This type of mask sheet contains various plant fibers, such as tea fiber, bamboo charcoal fiber, lotus leaf fiber, and seaweed carbon fiber. These plant fibers are more environmentally friendly and hygienic, and have good antibacterial, bacteriostatic, and adsorption properties. This type of mask sheet has a good skin care effect even when used with water. When used with essence, the two promote each other and complement each other for even better results.
