The gentle action and novel liquor
delivery system of this advanced machine, which also features
an advanced automated process control system, enables dyeing
and rinsing to be performed continuously and more efficiently.
The combination of machine design and process control allows
the whole process from loading to unloading to be performed
without stopping the fabric or draining and filling the bath.
The new system allows for continuous rinsing to be performed
more efficiently and in a shorter time, than wasteful 'drop
and fill' rinsing. By never stopping the fabric during the
process, quality is also improved as the fabric or draining
and filling the bath. The new system allows for continuous
rinsing to be performed more efficiently and in a shorter
time, than wasteful 'drop and fill' rinsing. By never stopping
the fabric during the process, quality is also improved as
the fabric environment can be constantly controlled. In order
to significant water and energy savings, the new machine has
enabled companies to increase productivity and improve product
quality. The benefits of investing in the new, cleaner technology
include:
Total cost savings give a payback of 1.6
year.Water use reduced by 55% and steam consumption by 46%.Shorter
processing time leading to 26% increase in capacity.Improved
process control.
Advanced Dyeing Technology : The advanced
jet dyer uses a unique twin nozzle system to deliver dye and
rinse liquors to the fabric in an extended intensive zone.
Fabric travels through the machine in a relaxed and open manner,
thus allowing improved colour penetration during dyeing and
greater water penetration during rinsing.
The process used is continuous. Draining
and filling can be avoided because the water is used more
efficiently. During rinsing, fresh water is introduced to
the fabric by the twin nozzle system. The large diameter nozzle
system ensures that the fabric is more easily penetrated.
Having a second nozzle doubles the rinsewater penetration.
To avoid recontamination of both the fabric and the dye bath,
the rinsewater, after travelling through the system, is diverted
away from the fabric by a novel liquor bypass. This contaminated
water is collected in a drain trough from where its discharge
into the local sewerage system can be controlled at an optimum
rate, under an existing consent.
