Absorbent article with improved liquid infiltration performance

摘要

An absorbent article, for instance a sanitary napkin, that allows liquid such as menstrual fluid to permeate quickly is described by Unicharm in US Patent 8 304 600. According to the company of Tokyo,Japan, the device features a series of raised ridge portions (2) and groove portions (1) in the topsheet (502). The fibre density (e.g. 0.01 -0.20 g.cm~(-3)) of the side edge portions (8) of each raised ridge portion in the thickness direction (TD) of the nonwoven fabric (110) is uniform, and is higher than the average fibre density in the raised ridge portions.
