Description

Sanitary towel absorption core without fluff pulp

Technical Field

The utility model belongs to the technical field of sanitary towel, concretely relates to sanitary towel that does not contain fluff pulp absorbs core.

Background

At present, sanitary napkins are available in various brands, and the used raw materials are various, and generally comprise a surface layer, an absorption layer and a bottom layer, wherein: the surface layer is usually made of non-woven fabrics, so that the surface layer has better flexibility but poor air permeability and water permeability; the absorption layer is made of paper pulp or wood pulp to absorb water; the bottom layer is a breathable basement membrane (PE membrane) for preventing leakage.

The sanitary towel absorption layer is mostly made of dust-free paper and cotton through heat sealing, and is mostly plane. The absorbent layer having such a structure has a relatively general liquid-absorbing effect and is likely to cause side leakage. In order to solve the problems, a section of rectangular polymer water absorption layer is additionally arranged in the middle of a core body of a sanitary towel produced by a plurality of manufacturers at present and is used for improving the liquid absorption capacity of the core body. However, the polymer water-absorbing layer has a liquid-absorbing area that is not large enough and is distributed in a plane, and the liquid-absorbing effect of the polymer water-absorbing layer still needs to be improved.

Therefore, it is difficult to consider the characteristics of dry and breathable sanitary napkins, water absorption and the like, and most women want to be protected comprehensively during menstrual period to avoid the embarrassment situation of side leakage and the like, so researchers in the technical field need to further improve the structure and performance of the sanitary napkins to meet the all-round needs of women during menstrual period.
