DEFINITION

Classification: 442/327

NONWOVEN FABRIC (I.E., NONWOVEN STRAND OR FIBER MATERIAL):

(under the class definition) 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.

(1) Note. Paper or felt are not to be considered as nonwoven fabrics for classification here.

28, Textiles: Manufacturing,

103, 115 for nonwoven fabrics made solely by a fiber entanglement or interlocking process without any other fabric processing prior to or following the entanglement or interlocking process.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

180, and 181 for processes used to form nonwoven fabrics comprising thermoplastic fibers (i.e., heat-induced bonding).

162, Paper Making and Fiber Liberation, 100, 231 for paper products made by a papermaking process without the addition of an additional fabric layer (i.e., woven, knit, or nonwoven fabric layer).

428, Stock Material or Miscellaneous Articles,

34.1+, for hollow or container type articles (e.g., tube, vase, etc.) containing nonwoven fabric; subclasses 174+ for a nonwoven product of uniform thickness but of nonplanar characteristics; and subclasses 195+ for nonwoven fabrics with a discontinuous coating, impregnation, or bond.
