  • Patent number: 9879138
    Abstract: The present invention provides thermosetting aqueous binder compositions of one or more diprimary diamine, e.g. lysine, or poly(primary amine), e.g. polyethylenimine, and one or more reducing sugar in which the number of equivalents of primary amine relative to the number of equivalents of carbonyl groups in the reducing sugar ranges from 0.4:1 to 2:1, the binders being suitable for use on fiber, nonwoven, woven web and finely divided substrates. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.
