DEFINITION

Classification: 442/276

Hydroentangled:

(under subclass 268) Subject matter wherein the fabric layers have been adhered to one another by hydroentangling.

(1) Note. In a hydroentangling process, liquid streams impinge against fibrous layers and penetrate thereinto and in the process displace enough fibers to cause interlayer penetration of fibers and fiber layer bonding as a consequence of interlayer fiber friction.
