Abstract
A polyamide fibrous substrate having deposited on it an amount of a composition effective to impart stain-resistance comprising a water-soluble or water-dispersible alpha-olefin/maleic anhydride polymer or a mixture of said polymers, and processes for preparing the substrates. The maleic anhydride polymer is used either in hydrolyzed form or in the form resulting from reacting it with a lower alkyl alcohol so as to form an alpha-olefin/maleic acid monalkyl ester polymer.
