Abstract
Abstract This invention relates to a new composition and process that affords "total stain protection" finishing of polyamide products, i.e., carpet. This composition of non-ionic fluorocarbon and sulfomethylated phenolformaldehyde condensates provides protection against oil and waterborne soils and in addition, protects the treated substrate against food colors by means of a one-step application.
