Class Information
Number: 442/327
Name: Fabric (woven, knitted, or nonwoven textile or cloth, etc.) > Nonwoven fabric (i.e., nonwoven strand or fiber material)
Description: Subject matter wherein the fabric comprising a fabric assembly having structural integrity of continuous or discontinuous strands or fibers held together in random or ordered (e.g., parallel, etc.) array by (a) mechanical interlocking (e.g., as a consequence of needling or hydroentangling, etc.) in the case of thermoplastic fibers, heat-induced bonding (i.e., fusing), or (b) an impregnation or coating of a bonding agent.
