Problems solved by technology

[0002] At present, the common absorbent cores for absorbing human and animal excrement on the market can be roughly divided into three types, namely wood pulp core, composite absorbent paper and non-woven composite core. The wood pulp core is made of non-woven or non-woven fabric. Dust paper wrapped with crushed fluff pulp / wood pulp, composite absorbent paper is made of viscose fiber, fluff pulp / wood pulp and acrylic-based superabsorbent polymer particles, etc. Non-woven fabrics and superabsorbent polymer particles are bonded by hot-melt adhesives, but the absorbent cores of the prior art need to be laminated multiple times during the manufacturing process, and fibers accumulate in the absorbent cores after lamination. It becomes very hard, so consumers feel that it is not soft enough during use. In addition, the absorbent core is so hard that the absorbent product cannot fit well on the absorbent part, and it is easy to cause leakage such as side leakage

Abstract

The invention relates to an absorbent core of a disposable absorbent article. The absorbent core comprises an upper polyurethane foam layer which is permeable to liquid and a lower wrapping layer which can absorb the liquid; the wrapping layer comprises a first outer sleeve body which is permeable to liquid and an inner accommodating cavity, and the accommodating cavity is internally provided withthe lower polyurethane foam layer and a particle layer which is uniformly paved on the upper surface of the lower polyurethane foam layer and is formed by mixing resin particles, organic acid particles and anhydrous bicarbonate particles. The polyurethane foam is compounded with high-water-absorptivity polymer particles, the organic acid particles and the anhydrous bicarbonate particles, a soft and elastic supporting material is provided while sufficient liquid absorption and liquid locking capacities are provided, and the comfort is high.
