Abstract: New and useful low viscosity polymeric colorant formulations are provided comprising extremely low amounts of viscosity modifiers that drastically reduce the overall viscosity of the resultant colorant formulation as compared with the viscosity of the colorants themselves. In such a manner, the resultant formulation facilitates the utilization of such polymeric colorants within certain coloring processes and methods requiring low viscosity formulations while simultaneously permitting substantial retention of the same high color strength characteristics of the unmodified colorants. Such an unexpected result thus permits production and utilization of a low viscosity formulation that does not sacrifice colorability to an appreciable degree for target substrates or media. The inventive formulations thus comprise any number of polymeric colorants, (i.e.

Abstract: A new method for spot dying nylon carpet requires no color theory nor use of a color wheel. The new method is distinguished from prior art methods primarily by the fact that the focus in on the hue of the spot at any given moment during the process, and that primary dye colors are applied in a sequence determined by the color of the spot. The method has been shown to work on both solid-color and multi-color nylon carpets. It is also effective for spot dyeing light-color (off-white) carpets. The method can also be employed to repair stained areas of a carpet by simply bleaching the stained area and redyeing the bleached area. Prior to the redyeing process, the area to be treated is subjected to several rinse and extract steps. A bleach neutralizer is then applied, allowed to remain on the area to be treated for about 5 minutes, then extracted without further rinsing.

Abstract: A process for dying materials containing natural or synthetic polyamides is disclosed. The process includes immersing the materials to be dyed in a dye bath containing an acid dye.
