Dyeing Process

Many different dyeing processes exist. In batch processes, a predetermined quantity of fiber or length of yarn or fabric is dyed. In continuous methods, very long lengths of yarn or fabric are dyed. In skein dyeing, yarns are wrapped around poles and vat dyed. In package dyeing, yarn is wound onto perforated tubes through which dye is pumped. In beam dyeing, yarn or fabric is wrapped around a large perforated beam through which dye is pumped. In beck and jet dyeing, fabric is loosely twisted into a long loop and circulated around reels and guide rollers into and out of the dyebath. Jig dyeing is a batch process in which the fabric is under tension during dyeing as it passes through the dyebath and winds onto one roller, reverses direction, and passes back through the dyebath and onto the other roller. In continuous dyeing, the dye is padded onto the fabric, excess dye is removed by rollers, and steam heat sets the dye.
