LIQUID-PERVIOUS SHEET AND METHOD OF MAKING THE SAME

WIPO Patent Application WO/2012/073514

A1

The present invention aims to provide a liquid-pervious sheet suitable to be used as a liquid-pervious topsheet of a bodily fluid-absorbent wearing article. One surface 58 of both surfaces 57, 58 of a liquid-pervious sheet 11 is formed with crests 61 and troughs 62 extending in parallel to one another in a longitudinal direction A and alternate in a transverse direction B. The one surface 58 is additionally formed at least in the respective crests 61 with a series of compressed debosses 70. In the respective compressed debosses 70, thermoplastic synthetic fibers forming the liquid-pervious sheet 11 more densely gather together than in zones surrounding the respective compressed debosses 70 and thereby maintain initial fiber formation of the individual thermoplastic synthetic fibers.
