Abstract

See full text

The present invention provides a heat-resistant nonwoven fabric wherein the nonwoven fabric is formed from a poly(phenylene sulfide) fiber, and 30% by weight or more of the poly(phenylene sulfide) fiber has a crystallinity of 25 to 50%. Moreover, the properties of the heat-resistant nonwoven fabric can be further improved by making the nonwoven fabric have a multilayer structure in which layers composed of a poly(phenylene sulfide) filamentary fiber and layers composed of a poly(phenylene sulfide) fine fiber are stacked and integrated.
