International Classification:

D02G 3/36
D01D 5/38

US Classification:

428375, 26417211

Abstract:

A fiber having a non-uniform composition is disclosed. The fiber includes a first domain having a first composition and a second domain having a second composition different from the first composition. The fiber includes an interphase region intermediate the first and second domains that includes a blend of the first and second compositions to provide a gradual transition from the first domain composition to the second domain composition. A method for making such fibers is also disclosed.

Abstract:

An extruded filament is provided having a cross-sectional configuration which permits a cut transverse section of the filament to function as a high definition tagging material, the extruded filament having contained therein along the direction of the longitudinal axis (the axis of extrusion) of the filament a multitude of extruded strand portions, which may be the same or different from one another from the standpoint of composition, visual or forensic effect, and which strand portions provide a multitude of pixel-like portions within a cross-sectional portion of the filament, which multitude of pixel-like portions, when taken together, comprise at least one pre-selected degree of identification whereby the tagging material may be differentiated or identified based on at least one degree of identification. A cut fiber or microparticle formed from the filament may be used to authenticate a product when used in association with the product.
