Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a carboxymethyl fiber composite non-woven fabric for facial masks. Background Art

[0002] Non-woven fabric is a kind of non-woven fabric. It is a new type of fiber product with soft, breathable and flat structure formed directly from polymer slices, short fibers or filaments through various fiber web forming methods and consolidation technologies. It is characterized by not producing fiber scraps, strong, durable, silky soft, and cotton-like feel. Non-woven fabric has good mechanical properties and liquid absorption properties, so it can be made into compressed facial masks and used with essence.

[0003] A compressed mask is a mask that can block the skin from contact with the outside world for a short period of time. It has the characteristics of moderate thickness and is easy to carry. When used, just put a grain in the liquid, it will expand naturally, and after opening it, it becomes a mask paper suitable for most face shapes. However, non-woven fabrics as compressed mask cloths have obvious disadvantages. They have poor affinity with the skin and are only a carrier of essence. In addition, when used in winter, the cold environment is not conducive to the opening of pores, and the essence cannot be fully absorbed. Utility Model Content

[0004] The utility model aims to provide a carboxymethyl fiber composite nonwoven fabric for facial mask, which aims to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: A carboxymethyl fiber composite non-woven fabric for facial mask, comprising: a composite non-woven fabric base, a hygroscopic and heat-generating layer and an antibacterial layer; the hygroscopic and heat-generating layer is arranged between the non-woven fabric base and the antibacterial layer; the non-woven fabric base is a carboxymethyl fiber non-woven fabric; the gram weight of the non-woven fabric base is between 5-10g / ㎡; the gram weight of the hygroscopic and heat-generating layer and the antibacterial layer is between 10-15g / ㎡.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the moisture-absorbing and heat-generating layer is a warm ginger fiber non-woven fabric.

[0010] The beneficial effects of the utility model are as follows: based on the carboxymethyl fiber composite non-woven fabric for the facial mask of the utility model, it is cut into the shape of a facial mask and prepared into a compressed facial mask. When using the facial mask, the facial mask is immersed in the facial mask liquid. At this time, the carboxymethyl fiber non-woven fabric is in a gel state and can fit tightly to the skin. The hygroscopic and heat-generating layer can absorb moisture and generate heat, thereby increasing the temperature of the facial mask during use, and can also improve the skin care effect when used in winter; the antibacterial non-woven fabric layer has both good antibacterial properties and bioabsorbability, which can reduce the contamination of the facial mask by air during use.

[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment 1

[0016] Combination Figure 1 The present embodiment is described in detail. A carboxymethyl fiber composite non-woven fabric for a facial mask comprises: a composite non-woven fabric base layer 1, a hygroscopic and heat-generating layer 2 and an antibacterial layer 3; the hygroscopic and heat-generating layer 2 is arranged between the non-woven fabric base layer 1 and the antibacterial layer 3; the non-woven fabric base layer 1 is a carboxymethyl fiber non-woven fabric; the gram weight of the non-woven fabric base layer 1 is between 5 and 10 g / m2; the gram weight of the hygroscopic and heat-generating layer 2 and the antibacterial layer 3 is between 10 and 15 g / m2.

[0017] Carboxymethyl fiber is the abbreviation of carboxymethyl cellulose fiber, which is made of carboxymethyl cellulose. The carboxymethyl cellulose is a type of cellulose ether made from viscose fiber after carboxymethylation. It has good biocompatibility and high hygroscopicity. Therefore, the carboxymethyl fiber composite non-woven fabric has high hygroscopicity, high moisturizing, air permeability and good biocompatibility, and is easy to use, safe and non-toxic. When used to make facial masks, its hygroscopicity is greater than that of Tencel masks, and it can store a large amount of essence while keeping the mask in close contact with the skin.

[0018] Furthermore, the hygroscopic and heat-generating layer 2 is a warm ginger fiber nonwoven fabric. The warm ginger fiber is prepared by adding ginger extract to a viscose solution using a viscose fiber preparation process, and has good antibacterial properties and hygroscopic and heat-generating properties. It can generate heat in a humid environment, thereby having good warmth retention properties.

[0019] Furthermore, the antibacterial layer 3 is a seaweed fiber non-woven fabric, and the seaweed fiber in the seaweed fiber non-woven fabric is an absorbable antibacterial seaweed fiber. Specifically, the preparation of the absorbable antibacterial seaweed fiber: dissolve sodium alginate in deionized water to obtain a sodium alginate solution with a mass percentage of 2.5%, and its viscosity is 15000mPa; use 2.5% calcium chloride as a coagulation bath, perform conventional wet spinning at 30°C, and the resulting primary fiber is post-stretched 1.5 times, then washed at 40°C, and then heat-treated at 60°C to obtain the absorbable antibacterial seaweed fiber. The absorbable antibacterial seaweed fiber has both good antibacterial properties and bioabsorbability, and the preparation process is simple, green, and pollution-free. The antibacterial layer 3 made of this fiber is suitable for making facial masks and can provide good antibacterial effects.

[0020] Furthermore, the non-woven fabric base layer 1, the moisture-absorbing and heat-generating layer 2 and the antibacterial layer 3 are compounded by hot pressing.

[0021] Embodiment 2

[0022] Combination Figure 2 This embodiment is described in detail. The difference from the first embodiment is that a water-repellent non-woven fabric 4 is laminated on the side of the antibacterial layer 3 away from the hygroscopic and heat-generating layer 2 by hot pressing, and the water-repellent non-woven fabric 4 is a graphene non-woven fabric.

[0023] Specifically, the graphene non-woven fabric is prepared from graphene / polypropylene composite masterbatch using a spunbond non-woven fabric manufacturing process. The preparation process of the graphene / polypropylene composite masterbatch is as follows: the two raw materials of graphene and polypropylene are mixed by a weightless mixer and a kneading machine, and the heat on the surface of the polypropylene is used to evenly adhere the graphene to the surface of the polypropylene particles to ensure that the graphene is evenly dispersed in the polypropylene and effectively combined with the polypropylene; the graphene is formed by multiple kneading and cross-linking by a twin-screw extruder, so that the graphene effectively enters the molten polypropylene particles to form. The graphene non-woven fabric has the characteristics of stable structure, water repellency, oil repellency, low resistance and breathability, which can prevent the essence in the mask from volatilizing into the air in large quantities. At the same time, the unique mesh structure and extremely high specific surface area of ​​graphene can be used to adsorb and filter particles and bacteria, reducing the pollution caused by contact with the air during the use of the mask.

[0024] Embodiment 3

[0025] The difference from the second embodiment is that the water-repellent nonwoven fabric 4 is PP nonwoven fabric, which is not only waterproof and breathable, but also environmentally friendly, flexible, non-toxic, tasteless and inexpensive.

[0026] The carboxymethyl fiber composite nonwoven fabric for the facial mask feels soft when used and has good moisturizing properties, so during use, the mask will not make the skin tight due to drying. The good moisturizing properties of the nonwoven fabric can keep the skin in a moisturized, soft and relaxed state throughout the use stage.

[0027] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
