Class Information
Number: 442/361
Name: Fabric (woven, knitted, or nonwoven textile or cloth, etc.) > Nonwoven fabric (i.e., nonwoven strand or fiber material) > Including strand or fiber material which is a monofilament composed of two or more polymeric materials in physically distinct relationship (e.g., sheath-core, side-by-side, islands-in-sea, fibrils-in-matrix, etc.) or composed of physical blend of chemically different polymeric materials or a physical blend of a polymeric material and a filler material
Description: Subject matter wherein the strand or fiber material, per se, is a monofilament composed of (a) two or more synthetic polymeric materials which are specified as being in sheath-core, side-by-side, islands-in-sea, fibrils-in-matrix, or any other physically distinct relationship across a cross section thereof, (b) a physical blend of two or more polymeric materials specifically disclosed and/or claimed as having distinctly different chemical or physical characteristics, or (c) a blend or an admixture of a polymeric material and a filler material.
