subclass is indented 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.|
Note. Paper or felt are not to be considered as nonwoven fabrics
for classification here.
115for 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.
Bonding and Miscellaneous Chemical Manufacture,
180 and 181 for processes used to form nonwoven fabrics
comprising thermoplastic fibers (i.e., heat-induced bonding).
and Fiber Liberation, subclasses
231for paper products made by a papermaking process without
the addition of an additional fabric layer (i.e., woven, knit,
or nonwoven fabric layer).
Material or Miscellaneous Articles, subclasses
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.
