DEFINITION

Classification: 442/50

Nonwoven scrim:

(under subclass 1) Subject matter wherein the scrim is a nonwoven fabric.

(1) Note. A nonwoven fabric is composed of strands or fiber material having structural integrity by forced interassociation of the strands or fiber material by mechanical means (e.g., needling, hydroentanglement, etc.) or by the effect of chemical binders or by autogenous bonding (i.e., heat- and/or pressure-promoted welding or solvent bonding).
