Abstract:
Disclosed is a method of making an acetate tow bands comprising identification fibers which can be used for tracking and tracing the acetate tow band 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 acetate tow band, including the manufacturer of the acetate tow band and the customer of the acetate tow band. The identification fibers can be produced on a cellulose acetate tow line using one or more spinnerets with spinneret holes to produce the taggant cross-section shapes and/or taggant cross-section sizes.
