Reverse osmosis preventing absorbing article and manufacturing process thereof

Abstract

The invention discloses a reverse osmosis preventing absorbing article and a manufacturing process thereof. The reverse osmosis preventing absorbing article comprises an absorbing article main body, a leg anti-leakage elastic component, an anti-leakage sheet, a waist elastic component, a fixing waist plaster and a fixing waist plaster fitting piece, wherein the leg anti-leakage elastic component and the anti-leakage sheet are respectively arranged on two sides of the absorbing article main body in the longitudinal direction; the waist elastic component is arranged on the absorbing article main body; the absorbing article main body comprises a water permeable surface layer, an absorbing core layer and a waterproof bottom layer which are successively arranged from top to bottom; the absorbing core layer comprises a lower absorbing core layer and an upper absorbing core layer which is compounded onto the lower absorbing core layer; the shape of the upper absorbing core layer is matched with that of the lower absorbing core layer; the upper absorbing core layer is provided with a through cavity which penetrates through the upper absorbing core layer from the thickness direction of the upper absorbing core layer along the length direction of the upper absorbing core layer; the length of the through cavity is greater than half of the length of the absorbing core layer and is smaller than the length of the absorbing core layer; the side wall of the through cavity is downwards inclined in the opposite direction; and the through cavity is matched with the upper surface of a position, which corresponds to the through cavity, of the lower absorbing core layer to form a reverse osmosis preventing region.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to an anti-reverse seepage absorbent article and a manufacturing process thereof. Background technique [0002] Absorbent articles such as paper diapers and sanitary napkins are commonly used sanitary products. Generally, absorbent articles are composed of three main components: a surface cover, an absorbent core, and a backing. The surface coating layer can also be called a coating layer or a water-permeable surface layer. The coating layer is close to the user's body, which can promote the rapid penetration of urine and effectively prevent back seepage, so that the surface layer of the diaper can be kept dry. At present, the covering layer of diapers in the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can circulate outside the diaper, and the moisture and heat can be...

AI Technical Summary

Problems solved by technology

[0003] When users use absorbent articles, they may not replace them immediately, or out of economical mentality, etc., they may not replace the absorbent articles immediately, which will easily cause the urine in the absorbent article to seep back onto the water-permeable surface layer , which will cause the surface to be wet and dry, which will bring discomfort to the user, and it is easy to breed bacteria. If the user is an infant, it is more likely to have skin problems such as rashes, red buttocks, etc.
