THREE-DIMENSIONAL POLYMERIC STRAND NETTING, DIES, AND METHODS OF MAKING THE SAME

摘要

Method and extrusion die (1030) for producing a three-dimensional polymeric strand netting, wherein a plurality of the polymeric strands (1070a, 1070b, 1070c) are periodically joined together in a regular pattern at bond regions throughout the array, wherein a majority of the polymeric strands (1070a, 1070b, 1070c) are periodically bonded to at least two (three, four, five, six, or more) adjacent polymeric strands, and wherein no polymeric strands are continuously bonded to a polymeric strand. Three-dimensional polymeric strand netting described herein have a variety of uses, including wound care, tapes, filtration, absorbent articles, pest control articles, geotextile applications, water/vapor management in clothing, reinforcement for nonwoven articles, self bulking articles, floor coverings, grip supports, athletic articles, and pattern coated adhesives.
