Abstract
Methods of making polymeric fibers are provided and include spinning a solution containing at least one polymer, a modified pigment having attached at least one organic group, and a solvent. The polarity of the solvent and the polarity of the modified pigment are selected such that the polymer is soluble in the solution and the modified pigment is maintained dispersed throughout the solution. The polarity of the modified pigment may be substantially the same as the polarity of the solvent. Fibers of acrylic-containing polymers and other polymeric fibers are also provided. Articles and reinforcing material containing the various fiber(s) are also described.
