ABSTRACT:
Hydrophilic glass fibers are formed by coating glass fibers with a blend of an amine-aldehyde with an acrylic. Evaporative cooler pads are produced by coating glass fibers with a blend of an acrylic and an amine-aldehyde during hot melt spinning of the glass fibers into a web, followed by drawing the web to expand the web or mat into a porous pad, and curing the pad to produce a dimensionally stable, hydrophilic, porous, glass fiber pad. Preferably, the glass fibers are coated with a binding/hydrophilic coating formed of a blend of a urea-formaldehyde with an acrylic. A method for cooling air using the hydrophilic, porous, glass fiber pads, and an improved evaporative cooler utilizing hydrophilic, porous, glass fiber pads is disclosed.
