ABSTRACT OF THE DISCLOSURE The disclosure describes an improvement in a process for producing a product having a dyed fibrous surface and being formed by supplying a polymer intermediate a backing material and a movable, heatable drawing surface, heating the polymer to render the polymer molten, separating the backing material from the drawing surface to provide a fiber-forming region in which fibers are formed from the molten polymer and adhere to the surface of the backing material, and introducing a cooling fluid into the fiber- forming region to stabilize the fibers as their viscosity increases following formation, the improvement comprising: (a) applying at least one vaporizable dye to at least one member of the group consisting of the polymer, the backing material and the drawing surface; (b) in the case where the dye is applied to the backing material, contacting the dye and the polymer prior to heating the polymer to render it molten; and (c) rendering the polymer in contact with the dye molten by heating to a temperature of at least the melting point of the polymer, whereby color is imparted to the polymer prior to stabilization of the fibers.
