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. For most bleached spots, which will have either white, yellow, or orange hues, the redyeing sequence generally begins with dilute primary blue dye. However, if the bleached spot were to have a blue or green hue, the sequence would preferably begin with dilute primary red dye. On the other hand, if the bleached spot were to have a purple or lavender hue, the sequence would preferably begin with dilute primary yellow. Based on the color of the spot, the bleached area is then sprayed with the appropriate dilute primary color dye, which is then vacuum extracted without rinsing. The spray and extract process is repeated until either the desired color is obtained or the slightest tinge away from the color to be matched is observed. For each primary color dye, it is best to under-dye the area rather than over-dye it for the first application of a particular primary color dye. As the spot changes color, the remaining two primary colors are employed in an order as though the redyeing process were just beginning.

Abstract translation: 现场染色尼龙地毯的新方法不需要色彩理论，也不需要使用色轮。 该新方法与现有技术的方法不同，主要是由于在该过程中任何给定时刻聚焦于斑点的色调，并且以由斑点的颜色确定的序列应用初级染料颜色的事实。 该方法已被证明可用于纯色和多色尼龙地毯。 对于斑点染色（灰白色）地毯也是有效的。 该方法也可用于通过简单漂白染色区域和再染色漂白区域来修复地毯的染色区域。 在再染色过程之前，待处理的区域进行几次冲洗和提取步骤。 然后施用漂白中和剂，使其保留在待处理的区域上约5分钟，然后在不进一步漂洗的情况下提取。 对于大多数白色，黄色或橙色色调的漂白斑点，再染色序列通常以稀释的初级蓝色染料开始。 然而，如果漂白斑点具有蓝色或绿色色调，则该序列优选以稀释的初级红色染料开始。 另一方面，如果漂白斑点具有紫色或薰衣草色调，则该序列优选以稀释的初级黄色开始。 基于斑点的颜色，然后用适当的稀释原色染料喷洒漂白区域，然后将其真空抽提而不冲洗。 重复喷雾和提取过程直到获得所需的颜色，或者观察到与待匹配的颜色稍微相距的色调。 对于每种原色染料，最好对该区域进行染色，而不是过度染色以便首次应用特定的原色染料。 随着现场改变颜色，剩下的两种原色就按顺序使用，好像重新打印的过程刚开始。
