Introduction
NTNP Overflow Dyeing Machine is mainly used for bleaching and dyeing various natural fiber fabric with weight in 50~1000g/square meter under normal temperature normal pressure, as well as some blended fabric, such as rayon, acrylic, polyester etc. For each slot of frivolous fabric inside can handle two cloths at the same time.

 

Working theory
The end-to-end ring-form cloth will be raised by the Cloth-lifting Wheel in the front cylinder and then be soaked into the double-stream sprayer and brought to the back cylinder through the Cloth Conducting Tube and Cloth Placing Tube and at last it will be placed orderly at the end of the cloth groove. Then under the effect of the weight of the cloth itself and the suction of the cycling pump, the cloth will slip to the front of the cloth groove and then the cycling of the whole dyeing process will be realized.

Advantages 
1.The machines is higher versatility, when light and thin materials processed no adjustment is need to smooth fabric running.
2.It process shorten time, total processing time as 5 hour(dark shape);
3. Lower liquor ratio, liquor ratio of 1:4~5 and smooth fabric running are maintained of capacity of within 70~100%;
4. Reduction of electrical power consumption, reduction of water consumption, steam electricity, saving on effluent treatment.

 

Technical features
1.Textile hoisting system:

Drive type textile hoisting system can reduce sliding problem between textile and hoisting rollers, and improve hoisting strength of hoisting roller, ensure that roller and textile synchronously operate, with the help of guide roller, textile come into the nozzles in the most orderly way.

2.Nozzle:
Provide the most soft textile treatment and optimal exchange conditions between dye liquor and textile, this nozzle provide stronger seepage force and more efficient fabric delivery capacity, textile is full surrounded by dye liquor in the nozzle, so textile in the nozzle is under slack condition to avoid fluffiness.

3.Textile kink self-unwrapping device:
once the textile on front end of nozzle kink, this device will stop the circulating pump immediately, at the same time lifting the rotary drum rotate in opposite direction, until the textile return to normal operation, then automatic operate in positive direction, this device doesn't need manual open the door or press the button to correct kink problem.

4.Fabric speed system:
Textile hoisting system and plaiting system operate synchronously, ensure textile take full advantage of fabric, to achieve max. Fabric load capacity and decrease textile kink.

5.Liquor separation and collecting system:
Liquor separation and collecting system ensures max. Loading textile capacity, reduce water consumption and max. Circulation rate of each tank. Liquor separation system also has one built-in fabric shake, drain the superfluous dye liquor to dye liquor place before textile accumulate in the fabric storage tank, then circulate, the circulation rate will be increased and get more uniform dye efficiency.

6.Washing system:
The liquor separated from textile will be collected and guide to overflow gullet and drain, it won't be re absorbed by textile, foul and foam float on the liquid level will be drained through collecting pipe, so that the washing water efficiency is high, save water supply volume and strengthen textile dyeing quality.

7.Drive model:
Hoisting system equipped with stepless speed change, frequency converting control reduction gear motor drive.
