Abstract
The present invention is directed to a durable and imaged flame-retardant nonwoven fabric that can be used for flame-retardant apparel and other related applications. The fabric is formed by providing a precursor web consisting of a blend of melamine fibers and aramid fibers. The precursor web is hydroentangled on a three-dimensional image transfer device for formation of the fabric. The resultant fabric provides desirable air permeability and Thermal Protective Properties.
