Abstract
There is provided a laminate of nonwoven fabrics for outdoor applications which has good resistance to ultraviolet light. The laminate has two meltblown layers sandwiched between spunbond layers to produce an SMMS laminate. The layers have a large amount of a UV stabilizer and metal oxide pigments. Such laminates are useful for car covers, awnings and canopies, etc. When the laminate is used as a car cover, it is preferred to skew the basis weights of the outer layers so that the layer against the car is significantly lighter than the other outer layer and to reduce the denier of the fibers in the layer against the car.
