Nonwoven of synthetic polymer with binder comprising salt of inorganic acid

摘要

Provided are non-woven of synthetic polymer, in particular 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 non-woven of synthetic polymer, in particular to spunbond polyester continuous filaments, is cured to form a water-insoluble polymer binder which exhibits good adhesion and thermodimensional stability.
