摘要：
A nonwoven fabric having a weight per unit area of 5 g/m.sup.2 to 500 g/m.sup.2 composed of a polyallyene sulfide fiber having a mean fiber diameter of 0.1 .mu.m to 8.0 .mu.m is provided. The nonwoven fabric of extra fine polyallylene sulfide fibers has superior heat resistance, wet heat resistance, resistance to chemicals and fire retardant properties, suitable for various filter applications.
