Abstract

The utility model provides a paper diaper which is good in side leakage prevention effect, high in using comfort level, and not prone to layering, caking and cracking after an absorption core absorbs liquid. The paper diaper comprises a liquid permeable surface layer, a liquid-tight bottom layer and an absorption body, wherein the periphery of the liquid permeable surface layer, the periphery of the liquid-tight bottom layer and the periphery of the absorption body are integrally connected, and the absorption body is arranged between the liquid permeable surface layer and liquid-tight bottom layer. Leakage prevention strips which stretch in the length direction of the absorption body are respectively arranged on the two transverse sides of the upper surface of the absorption core, and the leakage prevention strips are formed by winding hydrophilic material layers in a concentric circle mode. The paper diaper is characterized in that the absorption body is composed of the absorption core which is wrapped by an upper layer elastic sheet and lower layer hydrophilic non-woven fabric; the upper side faces of the leakage prevention strips are fixedly connected with the upper layer elastic sheet; long pressing grooves which stretch in the length direction of the absorption core are respectively formed in the positions, located on the inner side edges of the leakage prevention strips, of the two transverse sides of the absorption core; the upper layer elastic sheet and the lower layer hydrophilic non-woven fabric are mutually fixedly connected at the positions of the long pressing grooves.

Description

A kind of diaper

Technical field
