ABSTRACT Apparatus is described for fibrillating a woven fabric comprising warp and weft tapes of polypropylene, such as is currently used as a primary carpet backing, by repeated needling of the fabric. The apparatus includes a needle board on parts of which needles of generally rounded cross-section, preferably circular cross-section, are mounted to a density, preferably of the order of 120 needles per square centimetre with the tips of all the needles in substantially the same plane. During the reciprocation of the needle board to fibrillate the warp and weft in the woven fabric, the fabric is maintained in a planar configuration by a support which accommodates the tips of those needles which penetrate the fabric without damage to the needles.
