ABSTRACT:
This invention relates to a new process and group of products that are useful in preventing nylon and wool fibers, including carpeting and upholstery, from being permanently stained. Fibers can be permanently stained by food colors contained in foods spilled on the fiber. This new group of sulfonated phenol-formaldehyde or naphthol-formaldehyde and anionic surfactant compounds not only block the stain from the fiber but also minimizes any yellowing or discoloration of the treated fibers during the application and during the subsequent exposure to sunlight or commonly used lightfastness testing equipment.
