This machine has been specially designed to wet out the fabric for two phase steaming. Two phase printing is usually used for woven cloths printed with reactive or vat dyes.
After printing and drying, the cloth passes through a chemical mangle and then into a steaming chamber for fixation.
The machine is complete with chemical pad mangle with two horizontal rollers particularly suitable for two phase liquor application.
One chrome plated roller contacts the printed side of the fabric whereas a viscouselastic rubber roller works on the reserve side of fabric. Special pneumatic pistons ensure a regular and uniform squeezing. A double liquor trough allows applying the chemical by nipping or dipping under the rubber roller. Alternatively the liquor can be applied on the printed side using the chrome plated roller. A doctor blade is installed to keep the chrome plated roller always clean.
Perfect dyestuff fixation can be obtained with steam uniformly distributed at a constant temperature in the steaming chamber.
For reactive dye fixation process requires about 15 second at 130ºC using silicate or carbonate in the pad mangle. Chemical are put on the printed side of the fabric by the chrome plated roller of the mangle.
For vat discharge fixation process require 30 seconds at a temperature of 130ºC.
