Class 442
FABRIC (WOVEN, KNITTED, OR NONWOVEN TEXTILE OR CLOTH, ETC.)
Class Definition:
This is the class for woven, knitted, nonwoven, or felt
article claimed as a fabric, having structural integrity
resulting from forced interassociation of fibers, filaments,
or strands, the forced interassociation resulting from
processes such as weaving, knitting, needling
hydroentangling, chemical coating or impregnation, autogenous
bonding (i.e., heat- and/or pressure-promoted welding or
solvent bonding) or felting, but not articles such as paper,
fiber-reinforced plastic matrix materials (FRP), or other
fiber-reinforced materials wherein fibers are present only as
a filler material.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
This class is an integral part of Class 428 (after subclass
223). It incorporates all the definitions and rules as to
subject matter of Class 428.
This is not the location for a woven or knitted fabric which
is no more than, respectively, the product of a loom or
knitting machine which has not been further treated. Such a
product of a loom is classified in Class 139, subclasses
420+. Such a product from a knitting machine is classified in
Class 66, subclasses 169+.
This is the location for a woven or knitted fabric which has
been subjected to further treatment after having been
removed, respectively, from the loom or knitting machine, and
all treated and untreated nonwoven fabrics, except those
treated by a drying process or a chemical modification which
effects chemical reaction within the material composing the
woven, knitted, or nonwoven fabric. A fabric which has been
dyed or subjected to chemical modification effecting reaction
within the material composing the fabric is classified in
Class 8, except where the chemical modification results in
converting the material composing the fabric to carbon.
Carbon fabrics, per se, are classified in Class 423,
subclasses 447.1+.
This is not the location for nonwoven sheets produced by
wet-laying fiber slurries on a screen (i.e., papers). Papers,
per se, are classified in Class 162, subclasses 100+.
Fiber-reinforced plastic matrix materials (FRP) or
fiber-reinforced inorganic matrix materials, per se, are
classified in Class 428, subclasses 292.1+.
