ABSTRACT:
A process for the preparation of cleaning materials comprising a cleaning fibrous substrate and an oiling composition adsorbed and impregnated in said fibrous substrate, said process comprising contacting a cleaning fibrous substrate composed of cellulose fibers or a combination of up to 30 % by weight, based on the total fibers, of synthetic fibers and the remainder of cellulose fibers with an oil-in-water emulsion of an oiling composition consisting substantially of (a) an oiling agent composed of mineral oil, a synthetic lubricating oil or a mixture thereof and having a viscosity of 8 to 100 cps as measured at 100.degree. F., (b) 0.5 to 35 % by weight, based on the total oiling composition, of an amphoteric surface active agent or a surface active agent having in the molecule both cationic active and non-ionic active groups and (c) 0.3 to 5.0 % by weight, based on the total oiling composition, of a benzene-carboxylic acid ester having a solubility parameter of from 8 to 12.6, under such a pH condition that said surface active agent is allowed to exert a cationic activity, for a time sufficient for the emulsion to be rendered transparent, the oiling composition being present in an amount of 0.5 to 35% by weight based on the fibrous substrate on the dry basis; dehydrating the thus oil-impregnated fibrous substrate; and then drying the fibrous substrate.
