Abstract
A method and apparatus for the space dyeing of yarn while the yarn is in the form of a loosely gathered package, such as a conventional yarn skein, and which includes injecting an atomized spray of dye and air at a plurality of spaced apart locations in the package, and such that the dye contacts only a portion of the yarn. The resulting yarn is characterized by essentially random and relatively short colorband lengths, which avoid the formation of unsightly streaks or "chevrons" on the face of a fabric formed from the yarn.
Claims9
A method for space dyeing yarn to produce a multi-color pattern and which is characterized by essentially random and relatively short colorband lengths, and comprising the steps of
- dyeing all portions of a loosely gathered package of yarn with a base color, then
- penetrating the loosely gathered package at spaced apart locations with a plurality of elongate nozzles having a plurality of apertures along their length, and then
- injecting an atomized mixture of dye and gas from each of the apertured nozzles, with dyes of different colors being injected from different ones of the nozzles, whereby a random, multi-color dye pattern is produced on the yarn, and including separately supplying the dye and gas under substantially equal pressures to each of the nozzles at a point located immediately adjacent one end of each nozzle, to thereby assure that both the dye and gas will be injected from the nozzles and without an initial non-atomized squirt of dye being emitted therefrom.
