DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The following is combined with Figure 1-3 To further explain this application in detail,

[0028] The embodiment of the present application discloses a hyaluronic acid non-woven fabric, including a non-woven fabric core 100, wherein the non-woven fabric core 100 includes an upper hyaluronic acid non-woven fabric 1, an upper elastic water-permeable layer 2, an absorbent middle layer 3, a lower elastic water-permeable layer 4, and a lower non-woven fabric 5 arranged in sequence from top to bottom;

[0029] The upper hyaluronic acid non-woven fabric 1 includes a non-woven fabric substrate 11 and a hyaluronic acid layer 12 coated on the non-woven fabric substrate 11;

[0030] The nonwoven fabric substrate 11 includes a skin-friendly layer 1101 , a fragrance layer 1102 , and an antibacterial layer 1103 which are sequentially arranged from top to bottom.

[0031] The hyaluronic acid layer 12 in the upper hyaluronic acid non-woven fabric 1 can provide the natural moisturizing factor required by the skin, keep the skin moist and comfortable, and reduce skin dryness and discomfort. The absorbent middle layer 3 can effectively absorb urine and menstrual blood to prevent leakage and diffusion. The lower elastic water-permeable layer 4 and the aromatic layer 1102 and the skin-friendly layer 1101 in the non-woven fabric substrate 11 can provide good air permeability, prevent moisture and heat and bacterial growth, and keep the skin dry. The antibacterial layer 1103 in the non-woven fabric substrate 11 can inhibit the growth of bacteria and reduce the risk of odor and infection. This hyaluronic acid non-woven fabric can provide women with a more comfortable, safe and environmentally friendly sanitary napkin experience. By adding hyaluronic acid, it can effectively reduce the possibility of allergic reactions and skin irritation, providing a more comfortable use experience.

[0032] The hyaluronic acid layer 12 is attached to the non-woven fabric substrate 11 by coating with a hyaluronic acid aqueous solution.

[0033] The concentration of hyaluronic acid in the hyaluronic acid aqueous solution is 0-5%; this is mainly because hyaluronic acid is a macromolecular substance. As the concentration increases, the viscosity of the solution will also increase; when the viscosity is too high, the fluidity is poor, which is not conducive to effective liquid application, and uneven liquid application will occur. In order to avoid the risk of microorganisms in the hyaluronic acid chip cloth after drying, the moisture content of the hyaluronic acid chip cloth is ≤8%, and the water content is <0.6Aw.

[0034] The lower nonwoven fabric 5 comprises an antistatic layer 51 and a wear-resistant layer 52 which are arranged in sequence from top to bottom. The antistatic layer 51 is made of antistatic fiber, and the wear-resistant layer 52 is made of wear-resistant fiber.

[0035] The wear-resistant fiber has good wear resistance, which can reduce the wear and damage of the sanitary napkin caused by friction during use, and extend the service life of the sanitary napkin. The antistatic layer 51 and the wear-resistant layer 52 are made of antistatic fiber and wear-resistant fiber, which can reduce friction on the skin and improve the wearing comfort of the sanitary napkin. The antistatic fiber and the wear-resistant fiber improve the quality and reliability of the sanitary napkin by providing better antistatic and wear resistance, and can meet the needs of women in different usage situations.

[0036] The antistatic layer 51 can effectively prevent the generation of static electricity, reduce the irritation and discomfort of static electricity to the skin, and improve the comfort and safety of the sanitary napkin. The wear-resistant layer 52 can increase the wear resistance of the sanitary napkin, reduce breakage and damage caused by friction, and improve the quality and reliability of the sanitary napkin.

[0037] The upper elastic water-permeable layer 2 and the lower elastic water-permeable layer 4 are both elastic perforated breathable films.

[0038] The elastic perforated breathable film has good air permeability, allowing air and water vapor to pass freely, reducing moisture retention, and improving the air permeability and comfort of sanitary napkins. The elastic perforated breathable film has excellent elasticity and can adapt to the curves of the body, reducing pressure and friction on the body, and improving the comfort and usage experience of sanitary napkins. The elastic perforated breathable film has good safety and hygiene, can effectively prevent the growth of bacteria and viruses, reduce the risk of infection, and improve the safety and hygiene of sanitary napkins.

[0039] The absorbent middle layer 3 is made of absorbent non-woven fabric and is filled with polymer absorbent resin particles. The absorbent middle layer 3 is designed with wavy curved flow guide channels on the upper and lower surfaces.

[0040] The use of absorbent non-woven fabrics and filling with high molecular absorbent resin particles can improve the water absorption of sanitary napkins, quickly absorb and lock liquids, reduce leakage and reflux, and the upper and lower surfaces are designed with wavy curved flow diversion channels, which can guide the rapid flow of liquids and evenly distribute the liquids over the entire area of ​​the sanitary napkin, thereby improving the flow conductivity and use efficiency of the sanitary napkin. The wavy curved flow diversion channel design can provide better comfort, reduce friction and discomfort on the surface of the sanitary napkin, and improve the wearing comfort of the sanitary napkin. The absorption efficiency and flow diversion capacity of the absorption middle layer 3 are increased, the use experience and leakage-proof performance of the sanitary napkin are improved, and the use of high molecular absorbent resin particles can effectively prevent the growth of bacteria and viruses, thereby improving the safety and hygiene of the sanitary napkin.

[0041] The skin-friendly layer 1101 is made of real silk, the aromatic layer 1102 is woven with warp and weft threads, and natural aromatic particles are dispersed inside the aromatic layer 1102 , and the antibacterial layer 1103 is made of chitosan grafted seaweed fiber.

[0042] Silk is a natural protein fiber. The skin-friendly layer 1101 is made of silk, which has good moisture absorption and air permeability. It can provide a soft and comfortable touch and reduce skin irritation and allergic reactions. The aromatic layer 1102 can release a light fragrance to help cover up odors and enhance the user experience. At the same time, the natural fragrance particles used are skin-friendly and reduce the potential irritation of chemical ingredients to the skin. The chitosan in the antibacterial layer 1103 has natural antibacterial properties and can effectively inhibit the growth of bacteria, reduce the risk of infection, and improve the hygiene and safety of the sanitary napkin.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
