Sanitary absorption product

Abstract

The invention discloses a sanitary absorption product. The sanitary absorption product comprises a face layer, an absorption layer and an air-permeable bottom layer which are arranged from top to bottom in sequence, the absorption layer comprises a thickness-direction permeation absorption layer and a plane vertical / horizontal diffusion absorption layer, and the thickness-direction permeation absorption layer is made from a foaming material and located on the plane vertical / horizontal diffusion absorption layer; the plane vertical / horizontal diffusion absorption layer and the thickness-direction permeation absorption layer are adjacently arranged, the plane vertical / horizontal diffusion absorption layer comprises composite water-absorption paper, and the composite water-absorption paper comprises fiber nets on the upper and lower surfaces and fluff pulp on the middle layer. Since the foaming material in the thickness-direction permeation absorption layer has high aperture ratio and openings are mutually connected, during body fluid permeation, body fluid can quick permeate in the thickness direction, so that the body fluid is gathered for permeation in a small area, after permeation, few residues of the surface of the sanitary absorption product exist, the residual area is also small, and the fresh feeling is provided for people.

Description

technical field [0001] The invention relates to the technical field of absorbent products, in particular to a hygienic absorbent product comprising a thickness direction permeable absorbent layer and a planar longitudinal / transverse diffusion absorbent layer. Background technique [0002] With the improvement of people's living standards, hygienic absorbent products, such as sanitary napkins, baby diapers, adult diapers, etc., are widely used in women, babies, middle-aged and elderly people who are prone to urinary incontinence and mobile phones due to their convenient replacement and cleanliness. Inconvenient patients and other groups. [0003] Absorbent products commonly present in the market are usually composed of a surface layer, an absorbent core layer and a breathable bottom film. The absorbent core layer is mostly composed of dust-free paper, fluff pulp, etc., with an appropriate amount of super absorbent resin added. When in use, body fluid penetrates through the ...

AI Technical Summary

Problems solved by technology

However, due to the short fiber length of traditional dust-free paper and fluff pulp, the fiber length is about 10-30mm, so it is relatively fluffy, thick, and has poor diffusivity after absorbing body fluids, making absorbent products thicker and more efficient. Not high, when the body fluid discharge is large, it is easy to cause the leakage of body fluid due to local absorption and saturation

At the same time, the strength of non-woven fabrics and fluff pulp is low. After absorbing a large amount of body fluids, the absorbent core layer is prone to breakage and lumps, and because the fillers used in traditional fluff pulp or composite cores are all fibrous substances , After absorbing water, it will form a block, thus losing the air permeability. In severe cases, the absorbent product will leak, and the absorption performance will decrease, which will also make the wearer uncomfortable.
