ABSTRACT:
A resin-modified fiber filter formulation, fiber filter element, and method for improving dimensional stability, firmness and resiliency of a polyolefin fiber filter element comprised of crimped polyolefin fiber tow, by contacting filaments thereof with a formulation comprising a blend of resin and base polymer emulsions as precursors forming the active formulation "in situ", at a convenient station by removing water, the solid resin component of which must have a low molecular weight and approved softening temperature range to obtain the desired characteristics.
Typical resins are polyterpenes and hydrogenated rosin esters; typical base polymers are polyvinyl acetate and copolymers thereof with, e.g., ethylene or acrylates.
