<p>Carboxylated cellulosic fibers, comprising cellulosic fibers covalently coupled to a carboxylating agent through an ester bond, wherein the carboxylating agent provides a carboxyl group to the fibers, and wherein the carboxylating agent is a polycarboxylic acid having one carboxyl group separated from a second carboxyl group by either two or three atoms, wherein the carboxylated fibers have a water retention value greater than or equal to the water retention value of the fibers from which the carboxylated fibers are formed. Methods for producing the fibers and for producing fibrous products that incorporate the fibers are also disclosed.</p> |
