ABSTRACT:
A nonwoven textile fabric comprising a needled and drawn batt comprising intermixed acrylic fibers and additional fibers selected from the group consisting of polyester fibers, nylon fibers and mixtures of polyester fibers and nylon fibers, with at least a portion of said additional fibers being fused and the acrylic fibers being essentially unfused. The nonwoven textile fabric is produced by forming a batt comprising the acrylic fibers and the additional fibers, drafting and needling the batt and fusing at least a portion of the additional fibers of the needled and drafted batt while allowing the acrylic fibers to remain substantially unfused. Fusing the additional fibers is preferably accomplished by means of infrared radiation.
