Abstract
The method and product disclosed herein result in a needle-bonded fabric having a tufted fabric visual. This is accomplished by needling an unconsolidated web consisting of layers of two or more different colored fibers with a needle board having a reduced needle density and wherein the needles are arranged in the needle board in a predetermined pattern. The multi-layer web is processed through a fiber locker containing this reduced needle density board at a higher advance rate per stroke than normal production methods so that the space between the needle punches is greatly increased. The web is transported through the fiber locker in a continuous manner and produces the claimed product. One of the layers of the web is a blend of fibers of widely different fiber deniers and color.
