Jet and Soft-Flow Dyeing Machines
topic
Jet dyeing machines circulate fabric in rope form through a high-velocity dye liquor jet that propels the fabric around an oval path at liquor ratios of 4 to 8 litres per kilogram at 98 to 135 degrees Celsius, while soft-flow machines use a low-velocity overflow system that transports delicate fabrics at reduced mechanical tension for processing sensitive woven and knitted fabrics that would be damaged by the mechanical action of conventional jet machines.
Role
Provides the primary dyeing technology for woven and knitted fabric in rope form at moderate liquor ratios with efficient dye liquor circulation that maintains level dye uptake, with soft-flow machines extending jet dyeing capability to delicate fabrics including lightweight knits and crepe weaves where the turbulent jet would cause permanent creasing or surface distortion that the gentler overflow transport prevents.
