The invention generally relates to fabric dyeing, such as fabric dyeing using indigo or sulphur dyes. A process is provided which provides a dyed yarn having reduced dye penetration and a white core. The process involves modification of existing sulfur dye ranges to more efficiently and in an environmentally improved method produce dyed fabrics. The modification involves one or more of i) using of a barrier compound to subsequent dye applications; ii) performing a scouring stage without a caustic agent; iii) bypassing scouring and/or scour rising; iv) using sodium bicarbonate to control the pH of dye tanks; v) reducing the dye concentration and increasing the number of dye vats; and vi) adding a sizing stage to the dye range. The invention also is directed to yarns dyed on dye ranges through use of the process, and fabrics formed from the dyed yarns.

A method including obtaining a first dye powder; mixing the first dye powder with a liquid, to form a first dye mixture; disposing the first dye mixture in a container; pressurizing the first container; opening a first valve in fluid communication with the first container, thereby to dispense the first dye mixture into secondary container; and applying the first dye mixture from the secondary container onto a portion of a fabric article, to form a tie-dye pattern on the fabric article.
