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.

Nonwoven fabric laminate

A dust sock filter medium laminate is provided which has at least two nonwoven webs of microfibers which have an average diameter (using a sample size of at least 10) between about 10 and 25 microns and which webs have been joined by a method comprising the steps of (a) directing the component layers to a separation zone, (b) applying water in the amount of from about 5% to 25% based on the weight of the combined layers, (c) combining the component layers, (d) passing the combination through a sonic bonder operating within the range of up to about 40,000 cps against a patterned anvil to produce a corresponding pattern of thermal bond areas over about 3% to 25% of the surface area of the combination, and, (e) drying the sonically bonded combination.
