具有用于编码的表面标记的纤维

Fibers with surface markings used for coding
Abstract:
Disclosed are fibers comprising one or more branded fibers which exhibit surface markings in a repeated pattern along the length of the branded fibers. The branded fibers can be incorporated into yarns or fiber bands to represent supply chain information of the yarns, fiber bands, and/or articles made from the yards or fiber bands. In a specific example, branded fibers can be incorporated into an acetate tow band. The branded fibers can be recovered from a cigarette filter, the repeated pattern decoded, and supply chain information associated with the acetate tow used to make the cigarette filter, such as manufacturer, customer, ship to location, and even the acetate tow bale, can be obtained.
