HYDROENTANGLEMENT OF CONTINUOUS POLYMER FILAMENTS

摘要

A nonwoven fabric (8) comprises continuous polymer filaments (2) of 0.5 to 3 denier that have been hydroentangled in a complex matrix for interconnecting filament loops, and that is otherwise substantially free of knotting, or of otherwise wrapping about one another. A process for making a nonwoven fabric comprises continuously extruding polymer filaments of 0.5 to 3 denier onto a moving support (14), pre-entangling the filaments with water jets (12), and entangling the filaments with a second set of water jets (16) on a three-dimensional image transfer device.
