[0002] The non-woven fabric industry, especially the sanitary products non-woven fabric industry, has developed rapidly in recent years. With the development of non-woven fabric technology and the demand for the market development of terminal products, especially the sanitary products such as baby diapers and women's sanitary napkins, the requirements for the breathability and comfort of non-woven fabrics are getting higher and higher. The existing non-woven fabrics have certain limitations in these aspects, mainly manifested in: For baby diaper products, before the baby is 1 year old, it is basically loose stools. It is difficult for the existing non-woven fabrics to ensure that the loose stools can enter the non-woven fabrics smoothly, which leads to long-term direct contact between the loose stools and the baby's skin, poor comfort, and easy to damage the baby's skin; For women's sanitary napkin products, the existing non-woven fabrics are not easy for menstrual blood to enter the non-woven fabrics, and the menstrual blood is easy to contact with the skin and sticky on the skin, which is less comfortable to use. In addition, in order to increase the breathability of the product, the outside of the diaper or the outside of the sanitary napkin is also punched, but the hole type of the traditional punching method is small, and the actual breathability effect is limited.

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] like Figure 1 , Figure 2 As shown, a breathable and comfortable composite non-woven fabric of the utility model comprises a porous layer 1 and a support layer 2 laminated on one side of the porous layer 1, the number of the support layer 2 is one layer or at least two layers, and the porous layer 1 and the support layer 2 are both made of hot air non-woven fabric. In this embodiment, the hot air non-woven fabric is ES hot air cotton non-woven fabric. The porous layer 1 and the support layer 2 are fixedly connected by hot air bonding. Hot air bonding refers to a production method in which hot air is used to penetrate the hot air non-woven fabric on a drying device so that the bonding fibers therein are heated and melted to produce bonding. A plurality of air permeable guide holes 3 are provided on the porous layer 1, which penetrate the two opposite sides of the porous layer 1, and the air permeable guide holes 3 are formed in the porous layer 1 by puncturing or punching. In this embodiment, the air permeable guide holes 3 are formed in the porous layer 1 by punching, and the use of punching can further ensure the realization of the large aperture of the air permeable guide holes 3, so that the excrement is conveniently discharged from the large aperture air permeable guide holes 3. Each of the air permeable and air guiding holes 3 is in a closed geometric shape, and the maximum size of each of the air permeable and air guiding holes 3 is not less than 2 mm. In the existing multi-layer non-woven fabrics used for sanitary products, holes are generally punched in the non-woven fabric layer that needs to be punched, and then the holes are compounded with other non-woven fabric layers by spraying glue. In order to avoid glue leakage during compounding, the hole size is generally less than 1.5 mm in diameter. If it exceeds 1.5 mm, glue leakage is easy to occur, affecting the use of the compound non-woven fabric. The utility model adopts hot air non-woven fabrics for the porous layer 1 and the support layer 2, and punches a plurality of large-diameter air-permeable guide holes 3 with a maximum size of not less than 2 mm in the porous layer 1, and fixes the large-pore porous layer 1 and the support layer 2 to form a composite non-woven fabric by hot air bonding. When the composite non-woven fabric of the utility model is used on the inner side of sanitary products, the porous layer 1 is arranged in close contact with the skin, so that excrement such as loose stools and menstrual blood can flow out into the support layer 2 through the air-permeable guide holes 3 of the porous layer 1, avoiding direct contact between the excrement and the skin, improving the user's experience of breathable comfort, and solving the problem of easy glue leakage in traditional large-pore composites, thus avoiding the occurrence of glue leakage.

[0025] Among them, the closed geometric shape of the air guide hole 3 can be circular, elliptical, rectangular, square, or irregular geometric figures. Furthermore, the maximum size of the air guide hole 3 can be not less than 5mm. In the present embodiment, the maximum size of the air guide hole 3 refers to the distance between the two farthest points on the outer edge of the closed geometric shape of the air guide hole 3; in addition, "not less than" in the utility model is equivalent to "equal to or greater than". In the present embodiment, the closed geometric shape of the air guide hole 3 is an ellipse, and the major axis (ie, the maximum size) of the air guide hole 3 is not less than 5mm. One specific embodiment is: the closed geometric shape of the air guide hole 3 is an ellipse, the major axis of the air guide hole 3 is 8mm, and the minor axis is 3mm. Such a large aperture can make the excrement pass through and enter the support layer 2 more quickly, which can further improve the user's breathable and comfortable experience.

[0026] In one embodiment, the supporting layer 2 is one layer. In another embodiment, the supporting layer 2 is at least two layers, and two adjacent supporting layers 2 are fixedly connected by hot air bonding.

[0027] In the utility model, a plurality of air guide holes 3 are arranged in a plurality of rows, and each row of air guide holes 3 has a plurality of air guide holes 3. In one embodiment, the plurality of air guide holes 3 are all elliptical holes, and in each row of air guide holes 3, the long axis direction of each air guide hole 3 is perpendicular to the arrangement direction of the air guide holes 3 in each row, and the air guide holes 3 in two adjacent rows are arranged in an alternating manner, so that the air guide holes 3 in the lower row can be inserted between the two corresponding air guide holes 3 in the upper row, so that as many air guide holes 3 as possible are arranged on the porous layer 1 of the same area, so as to achieve faster discharge of excrement.

[0028] The composite nonwoven fabric developed by the applicant has achieved good test results in actual tests. The utility model can be applied to the inner layer of sanitary products such as diapers and sanitary napkins. The porous layer 1 is in direct contact with the user's skin, so that excrement can quickly enter the support layer 2 through the air permeable guide holes 3 and be separated from the user's skin, which can improve the actual effect of the product, give the user a new breathable and comfortable experience, and further protect their health. In addition, the utility model can also be used in the outer layer of sanitary products. The porous layer 1 is the outermost layer, which can improve the air permeability of the overall product and give consumers a new visual experience.

[0029] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.
