Abstract
This invention relates to a dual crosslinkable polymer/crosslinking system particularly suited for use in preparing high quality nonwoven products. The polymeric binders incorporate at least two different but reactive functionalities, i.e., hydroxy and carboxyl, and which are capable of reacting with two other multifunctional reactants, i.e., polyaldehydes and aziridines, each of which reacts with at least one of the functionalities present in the polymer. This selection of reactive functionality coupled with the selection of crosslinking agents permits ambient temperature cure.
