Liquid-permeable topsheet in disposable body fluids absorbent article

摘要

A topsheet used in a disposable body fluids absorbent garment comprises a plurality of first ribs extending in parallel one to another in one direction and a plurality of second ribs extending in parallel one to another so as to intersect the first ribs. Each pair of adjacent first ribs intersect each pair of adjacent second ribs to define an air- and moisture-permeably opened region around which at least one of the respective pairs of adjacent first ribs and adjacent second ribs have their crests configured so that, between each pair of adjacent intersections of the first and second ribs each of the crests underlies an imaginary straight line connecting this pair of adjacent intersections.
