Abstract
Provided are spunbond polyester mats using an improved curable composition. Such curable composition comprises the reaction product of an aldehyde or ketone and an amine salt of an inorganic acid. The composition when applied to spunbond polyester continuous filaments is cured to form a water-insoluble polymer binder which exhibits good adhesion and thermodimensional stability.
