ABSTRACT:
An improved method for manufacturing a relatively thick, needled, non-woven fiber padding eliminates the conventional step of initially making a laminated blanket of garnet formed, thin, oriented fiber layers. Instead, this method initially forms a thick, single layer blanket of loosely piled, randomly oriented fibers, which blanket is simultaneously compressed and tack needled incremently along its entire length to intertwine and mechanically interlock random portions of the fibers. Thereafter, the conventional needling step is applied to complete the padding.
