Patent abstract
Provided are nonwoven polymeric fiber webs using an improved curable composition. Such curable composition comprises a reaction product of an amine and a reactant in the form of an amino-amide intermediate. To the amino-amide is added an aldehyde or ketone to form the curable binder composition. The composition when applied to the polymeric fibers is cured to form a water-insoluble polymer binder which exhibits good adhesion and thermo-dimensional stability.
