THERE IS DISCLOSED A PROCESS FOR PREPARING FIBERS BASED ON OLEFIN POLYMERS CONSISTING ESSENTIALLY OF ISOTACTIC MACROMOLECULES, WHICH FIBERS HAVE IMPROVED RECEPTIVITY FOR DYESTUFFS OF THE ACID, METALLIZED, AND PLASTOSOLUBLE CLASSES. THE DYEING PROPERTIES OF THE FIBERS ARE MODIFIED BY MEANS OF BASIC NITROGEN-CONTAINING POLYMERS AND COPOLYMERS, SUCH AS THE PRODUCE OBTAINED BY POLYMERIZING EPICHLORHYDRIN WITH AMINIC COMPOUNDS, WHICH ARE TREATED WITH AN EPOXY COMPOUND IN THE COURSE OF GRANULATION AND/OR DURING SPINNING OPERATIONS. |
