Abstract
A nonwoven web material that contains fibers formed by compounding at least one polymer with a tackifier is provided. The nonwoven web material can be used as a wipe or tack cloth and can exhibit a dust holding capacity of at least about 10 grams/m2 and a lint potential of less than about 5 fibers/cm2. In addition to containing a tackifier that is compounded with the polymer(s) used to form the fibers of the web, the nonwoven web material can be textured, post-bonded, apertured, or treated with elemental fluorine gas to further improve its dust holding capacity and minimize lint production. In addition, the nonwoven web material leaves minimal residue after contacting a surface.
