Heat-resistant nonwoven fabrics

TLDR
In this article, a method for making a heat resistant nonwoven fabric is provided, in which a formaldehyde-free binder composition containing a carboxy group, or carboxyl anhydride, or salts of a car boxy group is used.
Abstract
A method for making a heat resistant nonwoven fabric is provided. A formaldehyde-free binder composition containing a carboxy group, or a carboxylic anhydride, or salts of a carboxy group; and a β-hydroxyalkyl amide contacts a nonwoven fabric containing heat-resistant fibers, and heating the binder composition is effected.
