UV STABILIZED OUTDOOR COVER WITH BARRIER PROPERTIES

摘要

A nonwoven fabric with UV stability having a layer of meltblown fibers (4) sandwiched between first and second layers of spunbonded fibers (6, 8) wherein each layer further includes a base resin selected from the group consisting of polypropylene and polyethylene; combined with melt processable additives which are a mixture of (i) at least two hindered amine light stabilizers; (ii) a processing aid selected from the group consisting of hydroxyl amines and phosphites; and (iii) a carrier resin selected from the group consisting of polypropylene and polyethylene. Other melt processable additives include pigments which are added to provide the desired color in the resulting fabric layer.
