Benefits of technology

The patent describes a method for making an acetate tow band by combining identification fibers and standard fibers. The identification fibers have distinct features that are representative of supply chain components associated with the acetate tow band. The method also involves detecting and counting the groups of identification fibers, which correspond to taggant fiber counts. The technical effect of this patent is to provide a reliable way to identify and characterize fiber samples in a supply chain.

Problems solved by technology

As stated above, there are many widely-used packaging and labelling taggants and anti-counterfeiting measures (ACMs) in many industries, but these more overt solutions are often susceptible to countermeasures such as destruction, modification, duplication, repackaging, or relabeling.

Sample Preparation for Fibers

examples 1 and 2

[0421]The fibers were washed with ether solvent to remove the spin finish and dyed red. The fibers were then stretched across a frame and epoxied together to form a rigid rod of encapsulated fibers. The epoxied rod of fibers was cut perpendicular to the fiber axis to form a sample of 3 micron thickness. The sample was placed endwise on a microscope slide with cover plate and observed and photographed under a microscope.

Sample Preparation for Filter Rods

examples 3-16

[0422]25 g of Electron Microscopy Sciences® Epo-Fix low viscosity resin with 3 g of hardener were mixed together. To the mixture was added 0.5 mL of dye mixture (14 g of ORCO® Orcocil Red B dye in 760 mL of ethanol). The mixture was stirred slowly until it was homogeneous. A 1.5-mL micro centrifugation tube was filled to ¾ capacity with the epoxy mixture. A 10 mm thick specimen from a filter rod was cut and placed on top of the epoxy. The filter was allowed to absorb the epoxy and the tube was placed in a tray and left in a controlled laboratory environment for up to 12 hours to allow the epoxy mixture to harden and embed the filter rod specimen. The specimen was removed from the tube by pitching the bottom of the tube with pliers.

[0423]The specimen was placed in a vice and a jeweler's saw was used to cut the specimen to a size suitable for the polishing chuck. The specimen was polished using the Allied MultiPrep polishing system with the following media and rotation speed sequence....

Abstract

Disclosed are 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 distinct features are detectable in a filter comprising the acetate tow band.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. 119(e) to U.S. Provisional Application Ser. No. 62 / 018,182, filed Jun. 27, 2014, U.S. Provisional Application Ser. No. 62 / 105,011, filed Jan. 19, 2015, and U.S. Provisional Application Ser. No. 62 / 160,930, filed May 13, 2015, each of which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The present disclosure relates to fibers comprising identification fibers with certain shapes, sizes, and numbers of distinguishable identification fibers. The characteristics of the identification fibers can be representative of specific supply chain information. The characteristics of the identification fibers can allow fibers to be tracked from manufacturing through intermediaries, conversion to final product, and / or the consumer. The present disclosure also relates to the method of making the fibers and the method of characterizing the fibers.BACKGROUND[0003]Many industries have...
