Problems solved by technology

When this kind of absorbent core satisfies the set liquid absorption volume and liquid absorption speed, its thickness is generally relatively large. After absorbing liquid, the entire absorbent body swells significantly, and the wearer's discomfort increases. Therefore, it is necessary to find an absorbent core. Thinner, higher wet strength products

Abstract

The invention provides an ultrathin absorption object, an absorption body of which has obviously reduced thickness. The ultrathin absorption object comprises a liquid permeating surface layer with integrally connected periphery, a liquid-tight bottom layer and the absorption body arranged between the liquid permeating surface layer and the liquid-tight bottom layer, wherein the absorption body is formed by sequentially overlapping and fixedly connecting a plurality of liquid absorbing material layers; each liquid absorbing material layer consists of base material and a plurality of super water absorbent resin covering layers which are arranged on the surface of the base material at internals and extend along the length direction of the base material; the width of each super water absorbent resin covering layer is not more than 20mm, the base material is one of liquid absorbing base material or liquid absorbing base material, and the super water absorbent resin covering layers between the adjacent liquid absorbing material layers are partly or completely staggered with each other along the width direction.

Description

technical field [0001] The invention relates to a disposable absorbent article, in particular to an ultrathin absorbent article. Background technique [0002] Disposable absorbent articles such as sanitary napkins and diapers are known, which include a liquid-permeable surface layer, an absorbent body, and a liquid-impermeable bottom layer arranged in sequence from top to bottom. For diapers, the diapers have Extending horizontally and longitudinally extending from the front waist region to the rear waist region, the front waist region of the diaper is provided with front waist stickers on the outer side of the liquid-impermeable bottom layer, and left and right waist stickers are arranged on the lateral sides of the rear waist region. When the left and right waist stickers are respectively fixed on the lateral sides of the front waist sticker, the diaper can be fixed on the wearer's waist to prevent it from falling off. For sanitary napkins, the liquid-impermeable bottom l...
