ABSTRACT:
A process for making stain resistant nylon fibers from a mixture of nylon and highly sulfonated nylon copolymer is disclosed. The highly sulfonated nylon has greater than about 4.0% weight of aromatic sulfonate incorporated into the polymer structure and an unexpectedly low solid particle content as measured by Flow Vision Particle Analyzer and melt filtration studies. Also disclosed is the process and composition of the highly sulfonated nylon copolymer.
