High-efficiency water-absorbing composite core as well as sanitary towel and paper diaper with same

Abstract

The invention relates to a structure used as the absorber of an absorbing product, particularly relates an absorbing structure used as the absorbing core or layer of a sanitary towel or paper diaper, and more particularly relates to a high-efficiency water-absorbing composite core. The composite core comprises a surface layer and a bottom layer which are made of fluff pulp or non-woven fabric; a layer of mixed materials is arranged between the surface layer and the bottom layer; the mixed materials comprise diatomite powder and borneol powder; the surface layer and the bottom layer are connected together by sewing thread; and the composite core is divided into a plurality of mesh structures by the sewing thread. Because the mixed materials comprise the diatomite powder and the borneol powder, and the diatomite powder is porous and has the high porosity of about 90% and strong water absorbing capacity, the speed of absorbing and diffusing the liquid of the composite core is increased. In addition, in the mesh structure, the composite core is not easy to cake, break or roll when being twisted.

Description

technical field [0001] The present invention relates to a structure used as an absorber in absorbent products, in particular to an absorbing structure used for absorbent cores or absorbent layers of sanitary napkins or absorbent cores or absorbent layers of paper diapers, specifically high-efficiency water-absorbent composite cores. Background technique [0002] At present, the absorbent cores or absorbent layers of sanitary napkins or paper diapers sold on the market are usually made of fluff pulp or non-woven fabrics. However, during the use of such sanitary napkins or paper diapers, the absorbent core or absorbent layer is prone to agglomeration, breakage or curling. This is mainly because the user will exert a twisting effect on the sanitary napkin or diaper when the user is active, and the absorbent core will expand after absorbing a large amount of liquid, so the squeezing or pulling force on each part of the absorbent core will be different, thus It is easy to ca...
