Abstract

Abstract A spunbonded liner material having a heavy loading of pigment, formed of a heavier denier than normal spunbonded fiber in a lightweight fabric. In a particularly preferred embodiment, the fibers are formed of polypropylene and the pigment is formed of titanium dioxide present in an amount between about 1 and about 6 percent by weight of the fabric. The fabric material further has an open area of between about 25 and about 50 percent with an average pore size of between about 15,000 and 35,000 square microns and a fiber denier of greater than 3. Masking is greater than two times conventional nonwovens.
