Atmospheric and HT Jigger Dyeing Machines
topic
Jigger dyeing machines process fabric in open width on two reversing rolls through a shallow trough at very low liquor ratios of 1.5 to 3 litres per kilogram, with HT jigger machines operating under sealed pressure at up to 130 degrees Celsius for polyester dyeing in open-width format, providing the low liquor ratio and open-width processing combination that jet machines cannot achieve for crease-sensitive heavy wovens requiring minimum water consumption.
Role
Provides open-width exhaust dyeing at the lowest liquor ratios of any exhaust machine for heavy woven fabrics where rope form processing is unacceptable and fabric weight makes jet machine transport impractical, with jigger dyeing being the primary method for heavy upholstery fabrics, canvas, and industrial fabrics requiring open-width processing with minimum water, dye, and chemical consumption per kilogram of fabric dyed.
