UV STABILIZED SPUNBOND FABRICS WITH ENHANCED TRAPEZOIDAL TEAR

摘要

A nonwoven fabric with UV stability having a spunbonded fabric layer (2) comprising a base resin selected from the group consisting of polypropylene and polyethylene; combined with melt processable additives; wherein said mel t processable additives 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 t he resulting fabric layer.
