ABSTRACT:
A stain-resist for polyamide textiles comprises blends of maleic anhydride/alpha-olefin polymers with sulfonated phenol-formaldehyde condensation products. The stain-resist blends are water-soluble at low pH, even in the absence of surfactant, and are strongly substantive and more resistant to yellowing than the condensation products.
