Abstract

Provided are spunbond polyester mats using an improved curable composition. The 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 used as a binder in the mat is cured to form a water-insoluble binder which exhibits good adhesion and thermodimensional stability.
