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 of the fibers, a fiber band, or. 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 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.

1. A method of characterizing a fiber sample wherein the fibers comprise identification fibers and standard fibers, wherein the identification fibers comprise multicomponent fibers, wherein each of the multicomponent fibers comprise 2 to 100 segments, wherein each of the identification fibers exhibits at least one distinct feature, wherein each of the multicomponent fibers exhibits the at least one distinct feature comprising one or more taggant segment counts, one or more taggant segment shapes, one or more taggant segment sizes, one or more taggant segment geometrical relationships, or one or more taggant segment pointers, wherein the identification fibers consist of one or more groups of distinguishable identification fibers, each group of the distinguishable identification being formed by the identification fibers having the same distinct feature or a same combination of the distinct features, the method comprising, (1) applying imaging technology to the fiber sample to generate stitched image data of the fiber sample,(2) detecting the groups of the distinguishable identification fibers based on the stitched image data,(3) determining a number of each of the distinguishable identification fibers for each detected group, wherein the number of the identification fibers in each detected 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 distinct features in each group of the distinguishable identification fibers and (ii) the one or more taggant fiber counts are representative of at least one supply chain component of the fiber sample, and (4) generating, based on the detection and determination, supply chain information correlating at least one group of the distinguishable fibers and at least one of the taggant fiber counts to the at least one supply chain component of the fiber sample. 2. The method of claim 1, wherein each of the identification fibers comprises 2 to 50 of the segments and wherein a number of the taggant fiber counts for each group of the distinguishable identification fibers ranges from 1 to 10. 3. The method of claim 1, wherein the multicomponent fibers have an island and sea configuration, with the segments being formed by 1 to 50 of the islands and the sea. 4. The method of claim 1, wherein the at least one distinct feature comprises one or more of the taggant segment counts and a number of the taggant segment counts ranges from 1 to 50. 5. The method of claim 1, wherein the at least one distinct feature comprises one or more of the taggant segment pointers and wherein a number of the taggant segment pointers ranges from 1 to 50. 6. The method of claim 1, wherein the identification fibers comprise acrylic, modacrylic, aramid, nylon, polyester, polypropylene, rayon, polyacrylonitrile, polyethylene, PTFE, or cellulose acetate fibers. 7. The method of claim 1, wherein the standard fibers comprise cellulose acetate fibers. 8. The method of claim 1, wherein the at least one distinct feature comprises one or more taggant optical properties, the taggant optical properties distinguishing the segments of the multicomponent fibers. 9. The method of claim 8, wherein at least one of the segments in each of the multicomponent fibers comprises at least one of Cromophtal Red 2030 (CAS No. 84632-65-5), Copper Phthalocyanine (CAS No. 147-14-8), FD&C Yellow Lake No. 5 (CAS No. 12225-21-7), anatase titanium dioxide, rutile titanium dioxide, and mixed-phase titanium dioxide. 10. The method of claim 1, wherein the at least one supply chain component comprises a manufacturer of the standard fibers a manufacture site of the standard fibers, a manufacture line of the standard fibers, a production run of the standard fibers, a production date of the standard fibers, a package of the standard fibers, a warehouse of the standard fibers, a customer of the standard fibers, a ship-to location of the standard fibers, a manufacturer of a fiber band comprising the fibers, a manufacture site of the fiber band, a manufacture line of the fiber band, a production run of the fiber band, a production date of the fiber band, a package of the fiber band, a warehouse of the fiber band, a customer of the fiber band, a ship-to location of the fiber band, a manufacturer of an article comprising the fibers, a manufacture site of the article, a manufacture line of the article, a production run of the article, a production date of the article, a package of the article, a warehouse of the article, a customer of the article, or a ship-to location of the article. 11. The method of claim 10, wherein the at least one supply chain component comprises the manufacturer of the standard fibers and the customer of the standard fibers. 12. The method of claim 10, wherein the at least one supply chain component comprises the manufacturer of the standard fibers and the ship-to location of the standard fibers. 13. The method of claim 1, wherein the standard fibers comprise cellulose acetate and the fiber sample comprises a portion of an acetate tow band, a portion of a filter rod and/or a cigarette filter. 14. The method of claim 13, wherein each of the identification fibers comprises 2 to 50 of the segments and wherein a number of the taggant fiber counts for each group of the distinguishable identification fibers ranges from 1 to 10. 15. The method of claim 13, wherein the multicomponent fibers have an island and sea configuration, with the segments being formed by 1 to 50 of the islands and the sea. 16. The method of claim 13, wherein the at least one distinct feature comprises one or more of the taggant segment counts and a number of the taggant segment counts ranges from 1 to 50. 17. The method of claim 13, wherein the at least one distinct feature comprises one or more taggant optical properties, the taggant optical properties distinguishing the segments of the multicomponent fibers. 18. The method of claim 17, wherein at least one of the segments in each of the multicomponent fibers comprises at least one of Cromophtal Red 2030 (CAS No. 84632-65-5), Copper Phthalocyanine (CAS No. 147-14-8), FD&C Yellow Lake No. 5 (CAS No. 12225-21-7), anatase titanium dioxide, rutile titanium dioxide, and mixed-phase titanium dioxide. 19.
