Abstract (en)
Water-dispersible, uniformly hydrophilic polyolefin fibers are prepared by treatment of an aqueous suspension of spurted polyolefin fibers with an aqueous solution of a water-soluble ionized reagent capable of being converted into hydrated solid particles submicron in size to form a dispersion of said fibers and then adding to the dispersion an ionic precipitant for the ionized reagent. Representative of the ionized reagent and the ionic precipitant are the sodium salt of hydrogenated rosin and papermakers' alum, respectively.
