[0004] However, in the waistline area, not only the material needs to be selected according to the fit when worn, but also the softness and air permeability of the waistline need to be considered. The simple laminated structure cannot balance the air permeability and the fit. SUMMARY

[0005] Therefore, the utility model provides a stepped multilayer elastic waistline absorbing article, which solves the problem that the fit and air permeability of the waistline of the existing absorbing article cannot be balanced.

[0006] To achieve the above-mentioned purpose, the utility model is realized by the following technical solutions:

[0009] Preferably, the waist-encircling portion further comprises a middle waist-encircling layer arranged between the inner waist-encircling layer and the outer waist-encircling layer, the middle waist-encircling layer extends from the longitudinal end of the absorbent article to between the waist region and the waist-crotch region, so that the cross section of the waist-encircling portion has a stepped structure.

[0010] Preferably, the middle waist-encircling layer is an elastic sheet material.

[0011] Preferably, the middle waist-encircling layer is a non-elastic sheet material.

[0012] Preferably, the outer waist-encircling layer extends to the crotch portion.

[0013] Preferably, the outer waist-encircling layer is an elastic sheet material.

[0014] Preferably, the outer waist-encircling layer is a non-elastic sheet material.

[0015] By adopting the foregoing technical scheme, the absorbent article has the following beneficial effects:

[0016] The technical scheme adopts a multi-layer structure of the waist-encircling portion, and according to the air permeability requirement of the product, a fine-denier elastic rubber non-woven fabric structure that is softer and has better air permeability is adopted on the side close to the human body, and different sheet materials can be adjusted according to requirements on the side away from the human body, so that different elasticity and air permeability are obtained; and, due to the double-layer structure design of the inner waist-encircling layer and the outer waist-encircling layer, the coverage range of the inner waist-encircling layer on the inner side is limited to ensure the air permeability; and the outer waist-encircling layer can have a larger coverage range according to different materials, so that the outer clothing layer has a softer and more comfortable touch, the whole absorbent article has a more comfortable touch, and the waist-encircling position is thicker, so that a gap between the waist-encircling portion and the human body is avoided, and the fit is higher.

[0021] The following will describe the implementation methods of the present invention in detail with reference to specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Example 1

[0023] refer to Figure 1 and Figure 2 A stepped multi-layer elastic waist absorbent article comprises a liquid-permeable surface layer 100, an absorbent core 200, and a liquid-impermeable bottom layer 300, wherein the length direction of the absorbent article is defined as the longitudinal direction, the width direction is defined as the transverse direction, the side that contacts the human body when worn is defined as the inner side, and the side that faces away from the human body is defined as the outer side;

[0024] The center of the absorbent article is further defined as a crotch portion b, with waist regions a at both longitudinal ends, and a waist crotch region c between the crotch portion b and the waist region a. A waist portion is laminated and arranged at the longitudinal ends of the absorbent article. The waist portion can be arranged at one end or both ends, but is provided at both ends in this embodiment. The waist portion is sandwiched between the liquid-permeable surface layer 100 and the liquid-impermeable bottom layer 300. The waist portion includes an inner waist layer 1 near the inside and an outer waist layer 2 near the outside. The inner waist layer 1 extends from the longitudinal ends of the absorbent article to the waist region a; the outer waist layer 2 extends from the longitudinal ends of the absorbent article to the waist crotch region c.

[0025] Specifically, the inner waist layer 1 is made of a fine-denier elastic non-woven fabric. The fine-denier elastic non-woven fabric is made by fixing a large number of fine-denier elastics on one or two layers of base fabric. This is well known to those skilled in the art and is not limited to the specific model selection. Compared with traditional elastic waistbands, the fine-denier elastic non-woven fabric is softer and more breathable.

[0026] The outer waist layer 2 is a non-elastic sheet. The non-elastic sheet selected here can have a certain thickness, thereby increasing the overall thickness and softness of the entire waistline. Alternatively, a mesh material with a hollow interior can be selected to ensure breathability under the increased thickness structure.

[0027] The technical scheme adopts a multi-layer structure of the waistline design, and according to the air permeability requirement of the product, the side close to the human body adopts a fine denier rubber non-woven fabric structure which is softer and has better air permeability, and the side away from the human body can adjust different sheet materials according to requirements, so as to obtain different elasticity and air permeability; and, due to the double-layer structure design of the inner waistline layer 1 and the outer waistline layer 2, the coverage range of the inner waistline layer 1 on the inner side is limited to ensure the air permeability; and the outer waistline layer 2 can have a larger coverage area according to different materials, so that the outer clothing layer has a softer and more comfortable touch, the whole absorbent article has a more comfortable touch, and the waistline position is thicker, avoiding the gap between the waistline and the human body, and having a higher fit.

[0028] In the embodiment, the outer waistline layer 2 extends from the longitudinal end of the absorbent article to the crotch area c; and correspondingly, the outer waistline layer 2 can also extend to the crotch b when needed; for example, in order to increase the support for the absorbent core 200 after liquid absorption, an elastic sheet material can also be used as the outer waistline layer 2 to obtain additional structural support for the absorbent core 200. And the elastic sheet material of the outer waistline layer 2 is designed to be longitudinally elastic to obtain elastic support along the length direction of the absorbent core 200, and has stronger support.

[0029] Embodiment two

[0030] Reference Figure 3 Compared with embodiment one, the waistline part further comprises a middle waistline layer 3 clamped between the inner waistline layer 1 and the outer waistline layer 2, the middle waistline layer 3 extends from the longitudinal end of the absorbent article to between the waist area a and the crotch area c, so that the cross section of the waistline part is in a stepped structure; under this structure, the transition between the inner waistline layer 1 and the outer waistline layer 2 is more reasonable, and there is no sudden thickness reduction to affect the touch; and under the premise of ensuring air permeability, the three-layer waistline part structure obtains a more abundant product line, and the outer waistline layer 2 is the same, the material of the middle waistline layer 3 can be selected according to requirements, such as the middle waistline layer 3 being an elastic sheet material or a non-elastic sheet material; or a liquid-impermeable material, so as to obtain more functional, size, and thickness products, and with the progress of material science, it has a very good and broad application prospect.

[0031] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
