High Temperature Overflow Dyeing Machine OH Series
lApplicable to various fabrics
With a specially-designed nozzle structure, it enables the fabrics
in loose and expanded conditions during the dyeing process. It has
an excellent performance in dyeing tight and heavy fabrics and can
eliminate the crease mark problem, which is usually seen in other
lTime and energy saving by using new technologies
1. The nice and efficient configuration which is built with a
vertical heat exchanger enables the condensed water to be drained
instantly and reduces the time duration in the shifting between hot
and cold water. Meanwhile, it can avoid the formation of water
scale, extend the service life of heat exchanger, and reduce time
and energy as well.
2. The integration of automatic stripper and lint collector can
save installation space, economize dye liquid and reduce the manual
stripping time greatly.
3. The Inlet pipe of the main pump has been optimized, the height
of water inlet has been lowered and hence the water consumption has
been reduced significantly.
4. Compared with other designs, U-shape fabric tank and cross
configuration of this new model can increase the loading capacity
by 20%, up to 300kgs per chamber approximately.
5. Unique fabric flowing tube with nozzle can reduce washing time
and water consumption.
The time duration of the whole dyeing process for pure cotton
fabric by using reactive
dyes is analyzed as follows.
Light color : 250mins.
Medium color: 270mins.
Dark color: 390minutes.
Min running liquor ratio (does not include water in the material)
is as low as 1:1.5. The water consumption of the whole dyeing
process for cotton fabric (per KG) by using reactive dyes is
analyzed as follows.
Light Color: 27.2kgs
Medium Color: 37.5kgs
Dark color: 47.4kgs
lGood and stable repeatability
Leading dyeing control system, in combination with dually balancing
flow feeding system as well as constant pressure and flow rate
nozzle control enhance fabrics dyeing to achieve a good dye
uniformity and high repeatability.
lErgonomics Vat Design
The height of machine and operation platform is lowered and size of
the operation platform is resized much smaller than usual, which
makes operation much more convenient. The bottom of the dye vat is
specially designed so as to reduce water storage and liquor ratio
With unique main vat circulation system, the temperature difference
of entire dye vat from top and bottom and evenness of feeding is
controlled at optimum conditions.
Rotating spray is adopted for main vat cleaning and the whole vat
is within the range of cleaning, ensuring more complete cleaning.
l Optional parts
The optional configuration of multi-functional stock tank can
improve working efficiency greatly.
Salt addition tanks are of new filling functions, ensuring quicker
and smoother filling.
The integration of automatic stripper and lint collector can save
installation space, economize dye liquid and shorten the manual
