Abstract
This invention relates to an improved process for providing fibrous polyamide materials and wool materials with stain resistance and superior lightfastness that are more durable against alkaline washing. This is accomplished by treating the materials with an aqueous solution comprising a combination of a partially sulfonated novolak resin, methacrylic polymer and a soluble aluminum compound or a combination of a partially sulfonated novolak resin and a soluble aluminum compound. This invention additionally relates to polyamide and wool materials as treated by the aqueous solution for imparting stain resistance and superior lightfastness.
