Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, in particular to a new type of diaper made of perforated non-woven fabric. Background Art

[0002] Diapers are daily necessities commonly used by babies. They are a general term for diapers, diapers, and pull-up pants. Dry diapers can keep babies sleeping all night long. Due to their strong water absorption, they are commonly known as "diapers".

[0003] The structure of traditional diapers mainly includes three layers, namely a liquid permeable surface layer, a middle core layer and a liquid impermeable bottom layer. The liquid permeable surface layer and the liquid impermeable bottom layer are both non-woven fabrics, while the middle core layer is a super absorbent resin (SAP).

[0004] The utility model patent with Chinese patent application number 202020349020.0 discloses a diaper, including: a diaper body; a connecting belt, both ends of the connecting belt are detachably connected to the diaper body, a first positioning portion is provided on the diaper body, and a second positioning portion cooperating with the first positioning portion is provided on the connecting belt, so that the connecting belt is connected to a predetermined position on the diaper body through the cooperation between the first positioning portion and the second positioning portion, and the connecting belt is located on the side of the human body, so as to solve the problems of low wearing comfort and poor adjustability of diapers in the prior art. The technical solution proposed by the above utility model is to adjust the diaper by detachably providing a connecting belt on the diaper body. On the one hand, the integrity is reduced, and on the other hand, although the comfort is slightly improved, the overall breathability of the product is not improved. Utility Model Content

[0005] Therefore, based on the above concept, the utility model proposes a new type of diaper using a perforated non-woven fabric, which solves the technical problem that the poor air permeability of the existing diapers during use causes discomfort to babies.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of diaper using perforated non-woven fabric, including a diaper body, the diaper body including a liquid permeable surface layer, an intermediate core layer and a liquid impermeable bottom layer, the liquid permeable surface layer and the liquid impermeable bottom layer are both made of perforated non-woven fabric, the liquid permeable surface layer is evenly provided with first breathable holes, the liquid impermeable bottom layer is evenly provided with second breathable holes, the center position of the diaper body is located at both sides of the width direction thereof, and the diaper body is provided with flexible and comfortable soft edges.

[0007] Furthermore, the first breathable hole groove does not completely penetrate the liquid-permeable surface layer, and the second breathable hole groove does not completely penetrate the liquid-impermeable bottom layer.

[0008] Furthermore, the aperture of the first air-permeable slot is 0.8 mm-1.0 mm, and the aperture of the second air-permeable slot is 0.3 mm-0.5 mm.

[0009] Furthermore, a high-efficiency absorption core is arranged in the middle core layer, and the high-efficiency absorption core includes a central part and an extension part, the central part is an elliptical plate-like structure, and the extension parts are symmetrically arranged at the two ends of the central part, and the extension parts are arc-shaped structures, and the length direction of the extension part and the length direction of the central part are perpendicular to each other. A guide groove is arranged on the high-efficiency absorption core, and the guide groove includes a first guide groove and a second guide groove which are interconnected, the first guide groove is arranged at the center position of the central part, and the second guide groove is a strip guide groove, and the second guide groove is arranged in the central part and extends to both sides of the width direction of the extension part.

[0010] Furthermore, the width of the second guide groove gradually decreases when the second guide groove extends from the central portion to the extending portion.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] Compared with the existing diapers, the technical solution proposed by the utility model can bring better air permeability by adopting a liquid permeable surface layer and a liquid impermeable bottom layer of a perforated non-woven fabric. At the same time, the non-woven fabric itself has air permeability. By adopting an incomplete penetration method, on the one hand, it will not affect the original performance of the non-woven fabric, and on the other hand, it can improve the air permeability of the diaper body; at the same time, by providing an absorption core structure different from the conventional one, it can bring more efficient absorption performance. Specifically, a first guide groove is provided on the central part, which serves as the main absorption part and can guide the liquid at the first time, and the second guide groove extends to the extension part to ensure that a large amount of liquid can be quickly guided to the extension part for absorption in an instant without the occurrence of insufficient local liquid carrying capacity or local agglomeration.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4 The utility model provides a new type of diaper made of perforated non-woven fabric, including a diaper body 1, wherein the diaper body 1 includes a liquid permeable surface layer 11, an intermediate core layer and a liquid impermeable bottom layer 13, wherein the liquid permeable surface layer 11 and the liquid impermeable bottom layer 13 are both made of perforated non-woven fabric, the liquid permeable surface layer 11 is evenly provided with first breathable hole grooves, the liquid impermeable bottom layer 13 is evenly provided with second breathable hole grooves 131, the center position of the diaper body 1 is located at both sides of the width direction thereof with leakproof partition edges 3, and the diaper body is provided with flexible and comfortable soft edges 2.

[0020] The first breathable hole groove and the second breathable hole groove 131 have the same structure, and the only difference between the two is the aperture size. The aperture of the first breathable hole groove is 0.8 mm, and the aperture of the second breathable hole groove 131 is 0.3 mm. The first breathable hole groove and the second breathable hole groove 131 need to be observed closely by the naked eye to be seen. The molding method is hot pressing. Therefore, the first breathable hole groove does not completely penetrate the liquid-permeable surface layer 11, and the second breathable hole groove 131 does not completely penetrate the liquid-impermeable bottom layer 13. For specific structures, refer to Figure 3 .

[0021] A high-efficiency absorption core 12 is arranged in the middle core layer, and the high-efficiency absorption core 12 includes a central portion 121 and an extension portion 122. The central portion 121 is an elliptical plate-like structure, and the extension portion 122 is symmetrically arranged at the two ends of the central portion 121. The extension portion 122 is an arc-shaped structure, and the length direction of the extension portion 122 is perpendicular to the length direction of the central portion 121. A guide groove 4 is arranged on the high-efficiency absorption core 12, and the guide groove 4 includes a first guide groove 41 and a second guide groove 42 that are mutually connected. The first guide groove 41 is arranged at the center position of the central portion 121, and the second guide groove 42 is a strip guide groove. The second guide groove 42 is arranged in the central portion 121 and extends to both sides of the width direction of the extension portion 122. The groove width of the second guide groove 42 gradually decreases when it extends from the central portion 121 to the extension portion 122. The front and rear waistline connections of the diaper body 1 are pressed by ultrasonic pressing to form a pressing groove 5.
