PILE PRODUCT AND METHOD OF MAKING THE SAME ABSTRACT OF THE DISCLOSURE A pile product defined by a plurality of fibers which may extend from a base, the fibers being formed of a poly- meric material of at least 90% by weight ethylene vinyl acetate copolymer (EVA). The pile product is formed by molding the heat softened copolymer in a mold defined by a plurality of small cross section, elongated cavities having a relatively large aspect ratio. Upon completion of the molding operation, the fibers are cooled and withdrawn from the mold cavities substantially without breakage or elonga- tion of the fibers to provide an improved pile product. The withdrawn pile product may be further treated to effect cross linking of the polymeric material for further improved characteristics of the final product.
