ABSTRACT:
A process is described for manufacturing fibrous materials such as carpet yarns and textile yarns, wherein the yarns contain at least two groups of differentially dyeable nylon filaments. The fiber chemical structure of the filaments is altered so that groups of nylon filaments in the yarn have at least two distinctly different dyeability properties. Each group of nylon filaments has an anionic polymer group difference of at least 20 microequivalents per gram of polymer, thereby providing visible differences in dye uptake.
