Abstract

A method and apparatus for pattern dyeing of textile substrates in which the dyeing is done in two stages. In the first stage, a dye is uniformly applied in a manner that allows the dye to fix on contact. The uniformly dyed substrate is then moved under a series of spaced arrays, each array being associated with a separate color and being comprised of a plurality of individually controlled liquid dye applicators. Liquid dye of a given color is selectively applied through one or more dye applicators as the substrate passes under the array associated with that color. The applied dye remains unfixed until the substrate passes under all the arrays and the patterning is complete, whereupon all dye applied by the dye applicators is fixed by steaming or other appropriate application of energy to the substrate.

Claims3

Dependent claims

A process for dyeing a textile substrate in a multi-colored pattern, said process comprising the steps of

a. applying uniformly a hot dye to said substrate in a manner that allows said dye to fix immediately upon contact with said substrate, thereby creating a uniformly dyed substrate on which said dye is fixed;
b. moving said uniformly dyed substrate past a series of spaced arrays, each array being associated with a liquid patterning dye of a specific color, and each array being comprised of a plurality of individually controlled liquid patterning dye applicators directed towards the path of said moving substrate;
c. patterning said uniformly dyed substrate by selectively actuating said liquid patterning dye applicators in at least one of said arrays to apply said liquid patterning dye, in pattern configuration and in a manner that does not fix said applied patterning dye upon contact, to said uniformly dyed substrate as said substrate passes said one array;
d. repeating said patterning step as necessary to apply liquid patterning dye from as many arrays as is necessary to produce the desired pattern on said uniformly dyed substrate;
and
applying energy to said patterned substrate to fix said liquid patterning dye.
