A non-thermoplastic crosslinked fibrous element comprising a blend of a non-thermoplastic, water-soluble hydroxyl polymer, a fast wetting surfactant comprising a sulfosuccinate surfactant comprising a C4-C7 aliphatic chain, and a non-hydroxyl polymer selected from the group consisting of:
- polyacrylamide and its derivatives;
- polyacrylic acid, polymethacrylic acid and their esters;
- polyethyleneimine;
- copolymers made from mixtures of the aforementioned polymers;
- and mixtures thereof, wherein the non-thermoplastic crosslinked fibrous element is produced from an aqueous solution comprising the non-thermoplastic, water-soluble hydroxyl polymer, the fast wetting surfactant, a crosslinking agent, and the non-hydroxyl polymer and wherein the non-hydroxyl polymer exhibits a weight average molecular weight of greater than 1,400,000 g/mol and a polydispersity of greater than 1.10 to 1.40, and wherein the non-hydroxyl polymer is present in the blend at a concentration greater than its entanglement concentration (Ce) and wherein the non-thermoplastic crosslinked fibrous element is cured at a curing temperature of from about 110° C. to about 215° C.
