Abstract

A method of treating fabrics comprises contacting the fabrics with an aqueous liquor having a pH less than about 7.5, such as between about 5.0 and about 7.0, the liquor containing a cationic fabric softener and lanolin. The liquor is formed by adding to water a composition containing the cationic fabric softener and the lanolin, the concentration of these components in the liquor preferably being from 50 ppm to 500 ppm. The lanolin may be replaced by a lanolin-like material such as derivatives thereof or one or more of the active constituents of lanolin either extracted therefrom or derived from other sources. Preferred ratios of cationic softener to lanolin are 20:1 to 1:20 by weight. A a liquor to flabric ratio of less than 25:1 is preferred. The method generally leads to a deposition of cationic softener and lanolin of less than 0.5% by weight of the fabric.
