Abstract
A multi-ply fabric is assembled from a plurality of plies including at least a single thermoreactive ply and a single fibrous ply. The method of combining the plies incorporates a hot pin perforator to simultaneously perforate and bond the thermoreactive ply to the fibrous ply. The multi-ply material finds utility in absorptive products having a liquid impervious perforated surface acting as a facing or covering for the absorptive inner plies.
