<p>A pile product comprising a plurality of relatively long, thin face fibers extending from a base is molded from a crosslinkable polymeric material. During formation of the fibers, crosslinking of the polymeric material is initiated by heat activating a substance incorporated in the polymeric material which promotes crosslinking. Crosslinking imparts hot strength to the pile fibers so that the pile product, while still hot, can be removed from the mold without materially deforming the fibers. Consequently, the time it takes to mold the pile product is significantly reduced, thereby increasing productivity and lowering the cost of the product. Moreover energy is conserved because the mold is not continuously cycled between high and low extremes in temperature.</p> |
