Problems solved by technology

But the structure of the sanitary napkin has the following defects: first, the concave hole of the sanitary napkin is arranged above the moisture-absorbing core and under the permeable layer, which is limited by the thickness of the entire towel body, so the concave hole provided cannot be too deep, so that the speed of penetration is accelerated. The effect is not ideal
Secondly, when there is a tide, because most of the menstrual blood is concentrated in the concave hole, the menstrual blood seeping down from the concave hole will suddenly concentrate on the upper part of the moisture-absorbing core, and the upper part of the moisture-absorbing layer below the concave hole area is likely to suddenly absorb moisture. It will inevitably affect the infiltration speed of menstrual blood in the concave hole, so that the menstrual blood will stay in the concave hole, thereby hindering the rapid infiltration of menstrual blood above the concave hole, and causing the surface of the towel body to be dry

Abstract

A composite sanitary napkin with liquid guiding-retaining function has a liquid penetrating top layer, an air-permeable bottom layer without liquid penetration, a hydroscopic core between said top layer and bottom layer, and optional liquid retaining layer. Its advantage is no leakage.

Description

technical field [0001] The invention relates to a hygroscopic article, in particular to a sanitary napkin for absorbing menstrual blood or other excrement. Background technique [0002] There are currently a wide variety of absorbent articles on the market which are designed to absorb and contain body fluids and other exudates and prevent soiling of the body and clothing.

[0003] Sanitary napkins of various sizes and shapes are widely used by women to absorb menstrual blood and other discharges. With the development of the times, people's concept of using sanitary napkins is also constantly changing. In addition to requiring sanitary napkins to meet the basic requirements of comfortable use and good absorbency, the requirements for leak-proof and breathable performance of sanitary napkins are also getting higher and higher. . At present, the main reason for side leakage and rear...
