Absorption core body with low reverse osmosis rate

Abstract

An embodiment of the invention discloses an absorption core body with a low reverse osmosis rate, and belongs to the technical field of hygienic products. The absorption core body sequentially comprises dust-free paper, a first absorption core body, fluffy cloth, a second absorption core body and hot air cloth from inside to outside, and the content of the high-molecular absorption resin in the first absorption core body is lower than that of the high-molecular absorption resin in the second absorption core body. As the content of the polymer absorption resin in the first absorption core bodyis larger than that of the second absorption core body, most of liquids can be absorbed by the second absorption core body in the liquid absorption process, less liquid is absorbed in the first absorption core body facing a human body, reverse osmosis of the liquids is reduced, and the comfort of a user is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of sanitary products, in particular to an absorbent core with a low reverse permeability rate. Background technique [0002] Absorbent core is a core product in disposable hygiene products and is a key component for absorbing various liquids. It can be used in children's diapers, adult diapers, women's hygiene products and other products. Among them, the absorption performance, cost and structural performance of the absorbent core often determine the success or failure of its market competition. [0003] Existing absorbent cores use polymer absorbent resin filled therein to absorb liquids. Due to the lack of proper structural design, the liquids will accumulate on the side facing the human body when absorbing liquids, which is prone to reverse osmosis. When the amount of liquid is large, the absorbent core facing the human body absorbs the liquid slowly. When the user is lying down...

AI Technical Summary

Problems solved by technology

[0003] The existing absorbent core uses the polymer absorbent resin filled in it to absorb liquid. Due to the lack of proper structural design, the liquid is accumulated on the side facing the human body when absorbing liquid, which is prone to reverse seepage

When the amount of liquid is large, the absorption rate of the absorbent core facing the human body is slow. When the user is lying down and the movement range is large, further side leakage of liquid will occur, which seriously affects the comfort of the user.
