[0025] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0026] A composite nonwoven fabric, such as Figure 1 As shown, it includes a first hydrophilic layer 1, a second hydrophilic layer 2 and a water-repellent layer 3 which are compounded together in sequence, the inner side of the first hydrophilic layer 1 is fully or partially compounded with the second hydrophilic layer 2, and the inner side of the second hydrophilic layer 2 is fully or partially compounded with the water-repellent layer 3; the first hydrophilic layer 1 includes a hydrophilic spunbond layer or a perforated hydrophilic spunbond layer, and the second hydrophilic layer 2 includes a hydrophilic spunbond layer or a perforated hydrophilic spunbond layer.
[0027] The first hydrophilic layer 1, the second hydrophilic layer 2 and the water-repellent layer 3 are compounded by hot melt adhesive. The hydrophilic force of the first hydrophilic layer 1 is equal to or stronger than that of the second hydrophilic layer 2. The first hydrophilic layer 1, the second hydrophilic layer 2 and the water-repellent layer 3 are all made of polypropylene fiber, and the gram weight of the first hydrophilic layer 1 and the second hydrophilic layer 2 is 13-18 gsm.
[0028] The three composite layers of non-woven fabrics can be combined in many ways, and the combination can be adjusted according to different hydrophilic and breathable usage requirements.
[0029] A composite nonwoven fabric, one side of which is hydrophilic and the other side is water-repellent. The hydrophilic side can contact with human skin to absorb sweat and remove moisture, while the water-repellent side can prevent liquids harmful to the human body from harming the user. For example, when used on diapers, the water-repellent layer 3 can prevent the liquid in the diaper core 41 from penetrating to the waistline. When used on doctors' protective clothing or surgical gowns, the hydrophilic side contacts with the human body, and the water-repellent layer 3 is on the outside. The water-repellent layer 3 can prevent liquids carrying viruses from splashing onto the protective clothing during surgery and causing harm to the doctor.
[0030] A diaper waist, such as Figure 2 and Figure 3 As shown, it includes a first hydrophilic layer 1 connected to the outer layer of the diaper body, a second hydrophilic layer 2 is compounded on the inner side of the first hydrophilic layer 1, the lower end of the second hydrophilic layer 2 extends downward to the top of the core of the diaper body, the top of the second hydrophilic layer 2 extends upward to the upper part of the waist of the diaper, and a water-repellent layer 3 as a physical water-proof belt is compounded on the inner side of the second hydrophilic layer 2, the lower end of the water-repellent layer 3 is connected to the inner layer of the diaper body, and the top of the first hydrophilic layer 1 is folded inward from the top of the waist of the diaper and extends downward to the top of the water-repellent layer 3. The height of the water-repellent layer 3 is 3 to 6 cm.
[0031] The first hydrophilic layer 1 adopts a perforated hydrophilic anti-adhesive cloth with strong air permeability, and the second layer can adopt a perforated hydrophilic anti-adhesive cloth or a non-perforated common hydrophilic spunbond cloth. When both layers use perforated hydrophilic anti-adhesive cloth, the perspiration speed is faster, and the air permeability and heat dissipation are better. When the second hydrophilic layer 2 adopts a non-perforated common hydrophilic spunbond cloth, the production cost of the product can be reduced, and the non-perforated second hydrophilic layer 2 can also improve the anti-reseepage effect, and cooperate with the water-repellent layer 3 to improve the overall anti-reseepage effect.
[0032] Currently, the non-woven fabrics used for waistbands on the market are all water-repellent. When sweating in summer, you will feel stuffy and damp, and the sweat produced cannot be effectively discharged. This non-woven fabric can effectively guide the sweat to keep the skin dry and comfortable. In addition, this waistband is thin, which makes it lighter, more comfortable and more breathable. Compared with other moisture-absorbing and sweat-wicking composite non-woven fabrics, it has lower costs and simpler materials.
[0033] The waist of the diaper is provided with a circle of water-repellent layer 3 at the position where the inner side of the waist is connected to the diaper body, which can prevent the urine in the diaper body from leaking upward and lock the urine in the core 41 of the diaper. The waist on the upper side of the water-repellent layer 3 is composed of three hydrophilic layers, which can absorb sweat and moisture well, and increase the wearing comfort of the diaper.
[0034] A diaper, such as Figure 2As shown, it includes a diaper waistband and a diaper body, the diaper body includes a core 41, a breathable film 42 is arranged on the outside of the core 41, a coating layer 5 is arranged on the outside of the breathable film 42, an inner hydrophilic layer 6 is arranged on the inner side of the core 41, the lower end of the water-repellent layer 3 is compositely connected with the top of the inner hydrophilic layer 6, and the first hydrophilic layer 1 of the diaper waistband is compositely connected with the coating layer 5 of the diaper body. The lower end of the water-repellent layer 3 covers the top of the inner hydrophilic layer 6. The top of the inner hydrophilic layer 6 extends upward and covers the top of the core 41, then continues to extend upward to cover a portion of the second hydrophilic layer 2, and then extends between the third hydrophilic layer 3 and the second hydrophilic layer 2.
[0035] As a specific implementation, the coating layer 5 is a water-repellent non-woven fabric.
[0036] As a specific implementation manner, the covering layer 5 is a hydrophilic non-woven fabric, and the covering layer 5 and the first hydrophilic layer 1 are integrally formed.
[0037] The second hydrophilic layer 2 does not penetrate the entire diaper, thus saving hydrophilic non-woven fabric material and reducing costs.
[0038] The water-repellent ring design on the waist of the diaper can prevent urine in the diaper core 41 from penetrating into the waist. At the same time, the waist is made of hydrophilic material, which can absorb sweat and moisture well. Diapers with this structural waist are more comfortable to wear and can prevent sweat from the waist from accumulating between the waist and the skin, ensuring that the waist skin is dry and comfortable.
[0039] The water-repellent layer 3 of the diaper waist covers the joint between the waist and the diaper body, increasing comfort. The use of a circle of water-repellent nonwoven fabric helps prevent urine from transferring to the waist. The first hydrophilic layer 1 is more hydrophilic than the second hydrophilic layer 2, which has a better effect of preventing back seepage and helps conduction to the first hydrophilic layer 1.
[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
