ABSTRACT:
A filter medium, a tackified binder composition and a method for providing a uniformly distributed tackifier on the glass fibers of an unwoven fiberglass web for improving filtration capacity and efficiency. An emulsified tackifier, such as polybutene, is mixed with a conventional binder composition and applied to the fibers before they are expanded into the web. The binder is cured in the conventional manner and the tackifier migrates to the surface on each fiber to enhance particle adsorption.
