Paper is not to be considered as nonwoven fabric for classification here.

This subclass is indented under subclass 246. Subject matter wherein the layers have been impregnated with a polymeric organic silicon compound or an organosilicon oxide polymer.
(1) Note. Organosilicon resins usually serve as water and heat-resistant lubricants and finishers and can impart stain resistance, water repellency, and an enhanced crease resistance and feeling of softness to fabrics treated therewith.
Page 4 runs from subclass 200 through subclass 249, continuing the strand material entries and moving into woven fabric. The opening entries classify multicomponent strand material: sheath-core strands, in which a strand or filamentary component contains two or more synthetic polymeric materials in sheath-core relationship across a cross section; islands-in-sea strands, in which two or more distinct polymeric materials stand in islands-in-sea relationship; and strand material formed as a blend of polymeric material and a filler material, with cross-references to Class 428 for a strand or filament, per se.
The page then turns to woven fabric characterized by a particular or differential weave, and on to fabric layers, including the definition of nonwoven fabric used in the classification: an assembly having structural integrity of continuous or discontinuous fibers held together in random or ordered array by mechanical interlock such as needling or hydroentangling, by heat-induced bonding in the case of thermoplastic fibers, or by impregnation or coating with a bonding agent — with paper expressly not considered nonwoven fabric for classification here. The page closes with the opening layer entries, including three or more fabric layers under subclass 246, and links to all seven pages and back to the Government Resources directory.
Class 442 subclasses 200 to 249, from multicomponent strand material through woven fabric weaves to the opening fabric-layer entries.
A strand, or a filamentary component of a strand, containing two or more synthetic polymeric materials in sheath-core relationship across a cross section, classified under subclass 200.
As an assembly with structural integrity of continuous or discontinuous fibers held together in random or ordered array by mechanical interlock, heat-induced bonding for thermoplastic fibers, or impregnation or coating with a bonding agent; paper is expressly excluded.
