Abstract
A composition for the treatment of fibrous materials which has the average molecular formula represented by the structure (I), r(nhconr'r'').sub.x (NHCOSO.sub.3.sup.- M.sup.+).sub.Y (I) where R is an organic radical, containing at least 6 carbon atoms; R' is an alkyl or aryl radical which may or may not contain substituents; R" is either hydrogen or an alkyl radical; x and y are each greater than zero and x + y .gtoreq.2; M.sup.+ is a monovalent cation or one equivalent of a polyvalent cation such that there is electrical neutrality in the molecule; and the molecular weight, as represented by the formula (I), is in excess of 500.
