Abstract

Disclosed are fibers comprising identification fibers which can be used for tracking and tracing fibers, yarns, fiber bands, and/or articles comprising the fibers through at least part of the supply chain. Each identification fiber exhibits at least one distinct feature. Each group of distinguishable identification fibers can exhibit a taggant cross-section shape, a taggant cross-section size, or combination of the same taggant cross-section shape and same taggant cross-section size. The distinct features and the number of fibers in each group of distinguishable identification fibers can represent at least one supply chain component of the fibers. The distinct features can be detectable in an article comprising the fibers.
