Abstract
A nonwoven fabric with UV stability and flame retardancy having at least one fabric layer. The fabric layer is made of a base resin, preferably polyolefinic, and a non-halogenated melt processable compound that is selected from the group consisting of N-alkyoxy amines and are combined into a homogeneous blend which is then either spunbonded or meltblown to form the fabric layer. A melt processable fluorochemical additive may also be combined into the homogeneous blend to provide liquid barrier properties to the fabric layer.
