Absorption product with body-fitting arc-shaped narrow crotch and preparation method of absorption product with body-fitting arc-shaped narrow crotch

Abstract

The invention relates to an absorption product with a body-fitting arc-shaped narrow crotch. The absorption product comprises a liquid-tight bottom layer and an absorption core layer, wherein an elastic component which is connected with the absorption core layer is arranged at a crotch position between the liquid-tight bottom layer and the absorption core layer; elastic force is produced by the elastic component at the crotch position in a horizontal direction, so that when the absorption product is under a free loosened state or a using state under the elastic force, an arc-shaped narrow crotch structure is formed in a crotch position of the absorption product; through the arc-shaped narrow crotch structure, when being used, the absorption product can be adapted to the body of a user; theelastic component can be arranged at the center region of the crotch position, and can also be cut into a first elastic component and a second elastic component, and the first elastic component and the second elastic component are symmetrically arranged on two longitudinal flanks of the crotch position; and a flank adjacent to a leakproof separation edge, of each elastic component extends to thebase of the corresponding leakproof separation edge in the width direction of the absorption product, and is integrally connected with the absorption core layer and the liquid-tight bottom layer.

Description

technical field

[0001] The invention belongs to the technical field of disposable sanitary products, and in particular relates to an absorbent product with a fit-fitting arc-shaped narrow crotch and a preparation method thereof.

[0002] technical background

[0003] Absorbent products are also called disposable absorbent products or sanitary products, including diapers, diapers, sanitary napkins, pull-up pants, etc., which have been widely used in personal hygiene care, making infants and other people who cannot take care of themselves Disposable absorbent products store excrement and isolate these excrement from the wearer's body, clothes, bedding, etc., which not only improves the convenience of care, but also protects the skin of infants and other people who cannot take care of themselves.

[0004] The absorbent medium of the absorbent product is an absorbent core, including traditional absorbent cores and composite absorbent cores blended with fluff pulp fibers and super...

Examples

Embodiment 1

[0043] as attached figure 1 As shown, the existing absorbent article comprises a liquid-permeable topsheet 5, a liquid-impermeable backsheet 1 and an absorbent core layer 4 disposed between said liquid-permeable topsheet and liquid-impermeable backsheet. In addition, leak-proof partitions 3 are provided on both longitudinal sides of the absorbent product, as well as a closure system and an elastic system for wearing and comfort, such as an elastic waist. Wherein, the liquid-impermeable bottom layer 1 is composed of a breathable bottom film 11 and a spun-bonded nonwoven fabric 12 . However, the existing absorbent products are uncomfortable and uncomfortable during use, and are prone to continuous friction on the skin of the wearer's legs, especially after the absorbent product sags due to the weight of the liquid absorbed, it is very easy to rub on the skin of infants and young children. Scratch marks or even redness and inflammation appear.

[0044] as attached Figure 2-4 ...

Embodiment 2

[0053] as attached Figure 5-6 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment provides a curved narrow crotch portion of the absorbent product through the following implementation methods:

[0054] The absorbent core layer 4 is formed by wrapping the composite core 41 laterally with the core wrapping layer 42. The two longitudinal sides of the core wrapping layer 42 wrap the surface layer of the composite core 41 and the two longitudinal sides bend inwardly towards the bottom layer. fold.

[0055] In this embodiment, elastic non-woven fabric (ie, elastic non-woven fabric) is used as the elastic component. Specifically, at the crotch position between the liquid-impermeable bottom layer and the absorbent core layer, an elastic non-woven fabric connecting the absorbent core layer and the liquid-impermeable bottom layer is provided, and the longitudinal length of the elastic non-woven fabric is It is 150-200mm; the lateral width can be ...

Embodiment 3

[0063] This embodiment provides further specific implementation manners for Embodiment 2. as attached Figure 7-8 As shown, the absorbent product is also provided with leak-proof partitions, specifically, a left leak-proof partition 61 and a right leak-proof partition 62 extending along the longitudinal direction are respectively provided on both sides of the width direction of the absorbent product, Each leak-proof partition includes a base, a free part connected to the base and located at the upper end of the base, and a telescopic part connected to the free part and located at the upper end of the free part. Specifically, the left leak-proof partition 61 is provided with a base 63 , The right leak-proof partition 62 is provided with a base 64 .

[0064] The structural feature of this embodiment is that the first elastic non-woven fabric 73C is close to the side of the left leak-proof partition 61 and extends to the base 63 of the left leak-proof partition 61 along the widt...
