Normal Temperature Softflow Dyeing Machine
Wuxi Sunsky Machinery Co.,Ltd [China] 
Normal Temperature Overflow Dyeing Machine UH Series:
l Applicable 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 dyeing machines.
l Time 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.
l Eco-friendly
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
l Good 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.
l Ergonomics 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 effectively
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 stripping time.
