FIBERS WITH PHYSICAL FEATURES USED FOR CODING

摘要

Disclosed are fibers which contains identification fibers. The identification fibers can contain a plurality of distinct features, or taggants, which vary among the fibers and/or along the length of the identification fibers, a fiber band, or yarn. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying distinct features, combinations of distinct features, and number of fibers with various combinations of distinct features and correlating the distinct features to supply chain information. The supply chain information can be used to track the fibers, fiber band, or yarn from manufacturing through intermediaries, conversion to final product, and/or the consumer.

主权项

1. Fibers comprising identification fibers,
wherein each of the identification fibers exhibits at least one distinct feature, wherein the at least one distinct feature comprises at least one taggant optical properties, wherein the identification fibers consist of one or more groups of distinguishable identification fibers, each group of the distinguishable identification fibers being formed by the identification fibers having the same distinct feature or a same combination of the distinct features, wherein a number of the identification fibers in each group of the distinguishable identification fibers is defined as a fiber count, wherein at least one of the fiber counts corresponds to a taggant fiber count, and wherein (i) the at least one taggant optical properties, (ii) the distinct features in each group of the distinguishable identification fibers and (iii) the one or more taggant fiber counts are representative of at least one supply chain component of the fibers.
