Inducing water bath dyeability in polypropylenic fibers by their blending with polyamide 6

Melted blends of polypropylene and polyamide 6 compatibilized with a poly(propylene)/maleic anhydride copolymer were extruded and stretched to give filaments. The polypropylenic fibers obtained by this method were found to be easily dyeable in an aqueous dyebath. The wet-washing at 40, 60, and 90°C and the light and dry-cleaning fastnesses of the new material appeared quite satisfactory.
