ABSTRACT:
Improvements in permitting brighter colorations within polypropylene fibers and/or yarns while simultaneously providing more efficient production methods of manufacturing of such colored fibers as well are provided. Generally, such fibers and/or yarns have been colored with pigments, which exhibit dulled results, or dyes, which exhibit high degrees of extraction and low levels of lightfastness. Such dull appearances, high extraction levels, and less than stellar lightfastness properties negatively impact the provision of such desirable colored polypropylene fibers and/or yarns which, in turn, prevents the widespread utilization of such fibers and yarns in various end-use applications. Thus, it has surprisingly been determined that brighter colorations, excellent extraction, and more-than-acceptable lightfastness characteristics can be provided, preferably, through manufacture with certain polymeric colorants that include poly(oxyalkylene) groups thereon. Fabric articles comprising such novel fibers and/or yarns are also encompassed within this invention.
