Abstract
The invention provides composite elastic nonwoven fabrics and the process of making them. The composite elastic fabrics of the invention include an elastomeric net and at least one fibrous web including binder fibers and which is intimately hydroentangled with the elastomeric net. At least a portion of the binder fibers in the hydroentangled fibrous web have been thermally activated thereby bonding the hydro-entangled web into a coherent, substantially unitary structure encompassing the elastomeric net.
