Soil release chemicals and method of application to glass fabric or fiber
Abstract
Abstract Soil release for application to glass fibers and fabrics which have been treated with acrylic resin, or acrylic resins, and dyes to give the fibers a base coat, which soil release comprises an aqueous emulsion of copolymers of acrylic or methacrylic acids with ester of acrylic or methacrylic acid, wherein the proportion of acid is high, ranging from about 25 to 80 percent acid, by weight, in combination with an aqueous solution of a nonyl or octyl phenol, reacted with from 9 to about 50 moles of ethylene oxide, and aqueous solution of a fatty alcohol or acid, which also has been reacted with 5 to 50 percent of ethylene oxide, the composition thus prepared being used as a finish bath treatment for glass fibers which have already been dyed or had a base color coating applied thereto, thereby to apply over the base color layer on a glass fiber or fabric a second molecular or semimolecular layer of this resinous material, which functions as a soil release and, also, by controlling the base dye system and amount of soil release obtain a fabric which is flame retardant.
