Multi-layered absorbent articles and process for their production.

摘要

A layered article with high fluid retention properties comprising A) at least one layer of a non-woven web having from 5% to 100% hydrophilic fibers and from 95% to 0% other fibers; and B) at least one layer of backing material integrally attached to the non-woven web; wherein the hydrophilic fibers are formed from (a) a copolymer having 25 mole % to 75 mole % of an alpha, beta-unsaturated monomer bearing at least one pendant carboxylic acid or carboxylate salt group, and 75 mole % to 25 mole % of a copolymerizable comonomer, wherein from about 20% to 80% of the pendant groups are carboxylic acid groups and from about 80% to 20% of the pendant groups are carboxylate groups and (b) a cross-linking monomer selected from heterocyclic carbonate compounds and compounds having at least two free hydroxyl groups.
