Patent ID: 8128712

Claim:
A process for protecting the colors of colored textile articles or for providing crease-resistance to textile articles, comprising the step of applying to said articles a composition consisting essentially of at least one anionic polysaccharide with a weight-average molar mass of greater than 250,000 g/mole, the native skeleton of which is a polysaccharide comprising: a main chain comprising identical or different anhydrohexose units, and branches comprising at least one neutral or anionic anhydropentose and/or anhydrohexose unit; wherein the anhydrohexose or anhydropentose units of said anionic polysaccharide are substituted or modified with at least one group, said group comprising an anionic group or a group that is optionally anionized at the working pH of said composition; the degree of substitution or of modification (DSi) of the anhydrohexose or anhydropentose units with said anionic or anionizable group(s) ranging from 0.1 to less than 3; wherein said polysaccharide is anionic.
