Fleckenabweisende, pigmentierte Nylonfasern und Verfahren zur Herstellung derselben

摘要

Producer-colored nylon fibers which are stain-resistant to acid dyes are made by adding pigment to nylon copolymers containing 0.25-4.0 percent by weight of an aromatic sulfonate or an alkali metal salt thereof. In addition process advantages relating to the use of the same copolymers in making pigmented nylon fibers are also disclosed.
