ABSTRACT:
The present invention is directed to a hydroentangled nonwoven fabric with improved flame retardant properties and the making thereof, whereby the nonwoven fabric is differentially entangled to collapse upon itself and self-extinguish upon burning. The self-extinguishing fabric further exhibits favorable tactile and ductile softness while obtaining sufficient physical strength.
