ABSTRACT:
Disclosed is a hydraulically entangled, autogenous-bonding, nonwoven composite fabric composed of a matrix of substantially continuous, thermoplastic polymer filaments and at least one substantially non-thermoplastic fibrous material integrated in the matrix so that the composite fabric is adapted to autogenously bond to itself upon application of heat. The hydraulically entangled, autogenous-bonding, nonwoven composite fabric may be suitable as infusion package material for applications such as, for example, tea bags and coffee filter pouches. Also disclosed is a method of making a hydraulically entangled, autogenous-bonding, nonwoven composite fabric.
