Description

Technical Field

[0001] This utility model belongs to the field of facial mask technology, and in particular relates to a facial mask cloth. Background Technology

[0002] Facial masks, as a common skincare product, are widely used in the beauty industry. Traditional mask sheets include non-woven fabric masks and paper masks. Although they have a certain moisturizing effect, these traditional mask sheets have problems such as poor affinity, average breathability, limited capacity to hold essence, and being thick and not fitting well, which limits their further development and application in the market.

[0003] To address the limitations of traditional facial mask sheets, a gel facial mask sheet has emerged on the market. This sheet is made from a spunlace base fabric through a finishing process. However, current gel facial mask sheets on the market still suffer from insufficient liquid absorption and retention, requiring further performance improvements. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a mask cloth with stronger liquid absorption and liquid retention capacity.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A facial mask sheet, comprising;

[0007] A core layer composed of a first fiber having a first length;

[0008] An outer membrane layer located on both sides of the core layer, consisting of a second fiber, wherein the second fiber has a second length and the first length is less than the second length;

[0009] The outer membrane layer wraps around the core layer to form a layered structure;

[0010] When the first fiber of the core layer absorbs water, it can form a gel-like substance.

[0011] Furthermore, the core layer is formed by air-forming the first fiber into a web, and the first fiber is arranged randomly.

[0012] Furthermore, the first fiber is sodium carboxymethyl cellulose fiber.

[0013] Furthermore, the degree of substitution of the sodium carboxymethyl cellulose fiber is 0.25-0.47.

[0014] Furthermore, the proportion of sodium carboxymethyl cellulose fiber is 10%-40%.

[0015] Furthermore, the length of the first fiber is 8-28 mm, and the length of the second fiber is 30-40 mm.

[0016] Furthermore, the core layer and the outer membrane layer are formed by hydroentangling reinforcement.

[0017] Furthermore, the outer membrane layer is formed by cross-laying.

[0018] Furthermore, the second fiber is one or more of Tencel Lyocell, cotton fiber, Centella asiatica fiber, and cupro fiber.

[0019] Furthermore, the basis weight of the mask fabric is 35-70 g / m². 2 .

[0020] The beneficial effects of this utility model are:

[0021] This invention relates to a facial mask fabric that utilizes a stable sandwich structure formed by short fibers in the core layer being wrapped by long fibers in the outer membrane layer. This structure helps improve the overall stability and durability of the mask fabric. Because the fibers in the core layer are shorter, during the reinforcement process, the fibers in the core layer are more easily covered and fixed by the longer fibers, thereby increasing the absorbency and retention capacity of the mask fabric.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] 1. Core layer; 2. Outer membrane layer. Detailed Implementation

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figure 1This invention discloses a facial mask fabric comprising a core layer 1 and an outer membrane layer 2. The outer membrane layer 2 is located on both sides of the core layer 1, and wraps around the core layer 1 to form a layered structure. The core layer 1 is composed of first fibers with a first length; the outer membrane layer 2 is composed of second fibers with a second length, and the first length is shorter than the second length. When the first fibers of the core layer 1 absorb water, they can form a gel-like substance. A stable sandwich structure is formed by the short fibers of the core layer 1 being wrapped by the long fibers of the upper and lower outer membrane layers 2. This structure helps improve the overall stability and durability of the facial mask fabric. Furthermore, because the first fibers have a shorter length, they are more easily covered and fixed by the longer fibers during the reinforcement process, thereby increasing the absorbency and retention capacity of the facial mask fabric.

[0028] In some embodiments, the core layer 1 and the outer membrane layer 2 are formed by hydroentangling. Hydroentangling is a nonwoven fabric manufacturing process that uses high-pressure water jets to reinforce the fiber web, causing the fibers to become entangled and intertwined, thereby forming a nonwoven fabric material with a certain strength and stability. Hydroentangling does not require traditional weaving or knitting methods, nor does it require adhesives or spinning, making it an environmentally friendly and cost-effective production method. This invention utilizes hydroentangling to reinforce the core layer 1 and the outer membrane layer 2. High-pressure water jets cause the long fibers of the upper and lower outer membrane layers 2 and the short fibers of the middle core layer to become intertwined, enhancing the sandwich structure of the mask fabric and forming a stable whole. During hydroentangling, the short fibers of the core layer 1 are wrapped by the long fibers of the outer membrane layer 2. This wrapping effect reduces the dissolution and glue loss of the short fibers in water, maintaining the integrity and functionality of the mask fabric, thereby increasing the absorbency and retention capacity of the mask fabric.

[0029] In some embodiments, the length of the first fiber is 8-28 mm, preferably 10 mm; and the length of the second fiber is 30-40 mm, preferably 38 mm.

[0030] In some embodiments, the core layer 1 is formed by air-laid web formation of the first fibers, wherein the first fibers are randomly arranged. Air-laid web formation is a method of uniformly distributing fibers across a web formation area using airflow, which helps to form a nonwoven fabric structure with a uniform texture. The fiber structure of air-laid web formation typically has good breathability, which facilitates air circulation and reduces the stuffiness felt during prolonged use of the mask. The randomly arranged fiber structure makes the mechanical properties of the mask fabric more balanced in all directions, improving the overall performance of the product.

[0031] Furthermore, the first fiber is sodium carboxymethyl cellulose (CMC) fiber. CMC fiber is a high-polymer fiber ether chemically modified from natural cellulose, which has good hygroscopicity, water solubility and the ability to form transparent gel. By using CMC fiber as the core layer 1, the mask fabric can be made more gel-like, absorbent and retain liquid, and it is highly controllable and easy to implement.

[0032] In a specific embodiment: the core layer 1 and the outer membrane layer 2 are reinforced by hydroentangling to form a sandwich structure. Since the upper and lower layers use 38mm fibers which are relatively long, and the middle layer preferably uses 10mm fibers which are relatively short, during the hydroentangling process, the CMC fibers are covered by long fibers under the piercing and entanglement of the water needle, thus tightly wrapping them in the middle without being exposed. This structure can prevent the gel generated by the CMC fibers when they come into contact with water during hydroentangling from falling off under the impact of water pressure.

[0033] Furthermore, the degree of substitution of the sodium carboxymethyl cellulose fiber is 0.25-0.47, preferably 0.4. Herein, the degree of substitution of the sodium carboxymethyl cellulose fiber refers to the average number of sodium carboxymethyl groups attached to each cellulose unit.

[0034] Furthermore, the proportion of sodium carboxymethyl cellulose fiber is 10%-40%, preferably 30%. The added sodium carboxymethyl cellulose fiber accounts for 30%. It should be noted that a higher degree of substitution and a higher proportion indicate a stronger gel feel in the mask fabric, resulting in greater liquid absorption and retention. However, if the degree of substitution is too high, too much sodium carboxymethyl cellulose fiber will be added, leading to adhesive loss. This preferred method achieves the best results.

[0035] In some embodiments, the outer membrane layer 2 is formed by mechanical combing and cross-laying. Mechanical combing and cross-laying help to form stronger physical entanglements between fibers, providing a foundation for subsequent hydroentangling reinforcement. Additionally, the evenly distributed and cross-laid fiber structure helps the mask sheet better conform to the facial contours, and this structure generally has good breathability, facilitating air circulation and reducing the stuffiness felt during prolonged mask use, providing a more comfortable user experience. Such a fiber structure also helps to improve the mask sheet's liquid absorption and retention capacity, allowing the mask sheet to absorb more essence and release it slowly, providing long-lasting nourishment to the skin.

[0036] Furthermore, the second fiber is one or more of Tencel Lyocell, cotton fiber, Centella asiatica fiber, and cupro fiber.

[0037] Tencel Lyocell is a man-made fiber made from renewable resources such as wood pulp. Due to the tiny pores in its internal structure, Tencel Lyocell fibers have excellent breathability and moisture absorption. These tiny pores also contribute to the fiber's excellent breathability. Furthermore, the fiber's surface is very smooth, giving it a skin-friendly feel, making it particularly suitable for direct skin contact. Cotton fiber is a natural, renewable fiber with a soft texture, minimal skin irritation, and is skin-friendly. Its excellent moisture absorption helps the mask sheet absorb and retain essence. Centella asiatica fiber has medicinal value and can be used to improve skin condition, promote skin health, and repair. Using Centella asiatica as the outer membrane layer 2 adds extra value to the mask sheet. Cupro fiber is very soft, and its softness makes the mask sheet more skin-friendly, reducing skin irritation. It also has extremely strong water absorption, helping the mask sheet absorb and retain more essence. In this case, Tencel Lyocell is preferred for the outer membrane layer 2. Other materials with similar properties can also be selected according to specific needs.

[0038] Furthermore, the basis weight of the mask fabric is 35-70 g / m². 2 40g / m 2 ,

[0039] In some specific embodiments:

[0040] Core layer 1: CMC material is selected, with a length of 10mm, a substitution degree of 0.4, and a proportion of 30%. The CMC material is randomly arranged by airflow web formation, and the fibers are dispersed and evenly deposited on a roller or screen with small holes to form a uniform fiber web.

[0041] Outer membrane layer 2: Made of Tencel Lyocell material, 38mm in length, 0.9D, formed by mechanical carding and full cross-laying to form a fiber web.

[0042] The core layer 1 and the outer membrane layer 2 are reinforced with hydroentangling to form a sandwich structure, resulting in the mask fabric of this invention. The mask fabric has a basis weight of 40 g / m². 2 This mask sheet has a strong gel feel, high liquid absorption and retention capacity, and strong liquid-locking ability. Compared with existing solutions, the liquid absorption capacity of this mask sheet is increased by 2-3 times, and the liquid retention capacity is increased by 1.5-2.2 times.

[0043] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
