Abstract
A process for making multi-colored fabrics from a single dye formula is described. The process involves providing a substrate including synthetic fibers, with the substrate having defined regions where the synthetic fibers have differing levels of fiber orientation, and dyeing the substrate with a dye bath containing at least one dye from at least two of the categories of a) high contrast dyes, 2) medium contrast dyes and c) low contrast dyes, to thereby produce a multi-colored substrate from a single dye formula. The substrates are characterized by having a base of a first color and patterned regions of a different color, with the regions of different colors corresponding to regions of different levels of fiber orientation.

A method of making a multi-color textile substrate using a single dye formula comprising the steps of:
- providing a substrate containing synthetic fibers, wherein the substrate has base regions where the synthetic fibers have a first fiber orientation and patterned regions where the synthetic fibers are less oriented than the fibers in the base regions,
- performing a number of individual dyeings using individual dyes on said fabrics to produce a plurality of dyed fabrics;
- categorizing said dyed fabrics according to whether the base regions and patterned regions exhibit high contrast, medium contrast, or low contrast;
- then
- dyeing the substrate with a single dye formula containing at least one dye from at least two of the categories of a) high contrast dyes, b) medium contrast dyes, and c) low contrast dyes, to thereby produce a multi-colored fabric.
A multi-colored substrate comprising:
- a substrate containing synthetic fibers, wherein said substrate comprises base regions where the synthetic fibers have a first fiber orientation and patterned regions where the synthetic fibers are less oriented than the fibers in the base regions, wherein the patterned regions are of a different color from said base regions, wherein the color in the base regions contains the same dyes as the color in the patterned regions, and wherein the patterned regions contain a greater concentration of at least one dye than the base regions and substantially the same concentration of at least one dye as the base regions.
