Photostabilization package usable in nonwoven fabrics and nonwoven fabrics containing same

摘要

A stabilizing additive package for nonwoven fabrics is provided. The package has a bismuth vanadate based pigment and a hindered amine light stabilizer. The bismuth vanadate is added to a nonwoven fiber polymer prior to extrusion in an amount between about 0.1 and 3 weight percent based on the weight of the fabric and the hindered amine in an amount between about 0.25 and 2.5 weight percent based on the weight of the fabric. The nonwoven fabric also provided by this invention may be used as protective covers for, for example, boats and cars, and as an outdoor fabric for, for example, canopies and tents.
