DEFINITION

Classification: 442/245

One of which is a nonwoven fabric layer:

(under subclass 244) Subject matter wherein at least one fabric layer is nonwoven.

(1) Note. A nonwoven fabric is an assembly having structural integrity of continuous or discontinuous fibers held together in random or ordered (e.g., parallel, etc.) array by (a) mechanical interlock (e.g., as a consequence of needling or hydroentangling, etc.), (b) in the case of thermoplastic fibers, heat-induced bonding (i.e., fusing), or (c) an impregnation or coating of a bonding agent. Paper is not to be considered as nonwoven fabric for classification here.
