Super Environmental U-Flow Fabric Dyeing Machine
QRD SUPER ENVIRONMENTAL U-FLOW DYEING MACHINEQRD series uniform flow dyeing machine is an energy-saving and environment-friendly dyeing machine. Besides saving energy and optimiazing the dyeing techniques, this model of dyeing machine keeps the basic principle of overflow dyeing machine. It has a low bath ratio of 1:3. Compared with the traditional dyeing machine, total water, electricity and steam consumption is greatly reduced. According the cost of production is reduced and impact on environment is minimized.Innovative Technology
The dynamic movement of the treatment bath is obtained by means of a developed system, that creates a transverse flow to the direction of the fabric advancement. This innovative device, permits a rapid and homogeneous mixing of chemical and dye products.
The moved bath also guarantees other essential parameters:
The uniformity of the treatment bath in every space inside of the machine.
The perfect repeatability of the treatment.
A greater interaction of the bath/fabric, benefiting at the end the relaxation of its textilestructure. It will be possible to treat delicate and sensitive fibers without any particular problem.
Higher water efficiency, with reduction of some washing phases.Possibility to carry out treatments of open-width knitted fabrics.QRD series uniform flow dyeing machine has the dye liquor uinformli deliverying system. It enables a perfect bath distribution, with an identical delivery per nozzle. This system removes all delivery differences between nozzles resulting from preferential paths, to either inhomogeneous distributions or a decrease in the delivery according to the distance from the feeding point.QRD series uniform flow dyeing machine ensures fabric softness, smmothness, no pilling or abrsions and increases the fabric conveyance speed. The nozzle flow can be adjusted by the computer controller according to different.
The machine bottom area extremely reduces the bath ratio and makes enough room for dye liquor flowing.
The feeding system of both dyestuff and higher dilution chemicals allows for the fast measuring.Additional Preparation Tank
QRD series uniform flow dyeing machine which has one more addtional preparation tank than normal dyeing machines. Customers can choose double feeding machines if needed. Dyeing liquor can transfer among preparation tank, Chemical tank and main tank. The preparation tank and chemical tank have the same function of measuring, and hence it solves tank volume issues to dissolute salt and sulphates. In actual use, the preparation tank has onter functions:
When the dyeing process almost finishes, water can come into the preparation tank and be heated to the set temperature under the control of the computer system water will be injected into the main tank in the washing process.
Water from steam trap or cooling water can be recycled by the preparation tank.
The chemicals from the chemicals tank can be injected into the preparation tank first, and the chemicals tank keeps on working.
When the feeding programme works, chemicals go to the main tank from the preparation tank.
If the main tanks needs to be repaired during the runing process, inject the cooling dyeing liquor to the preparation tank. It can reduce the impact of dyeing liquor on the environment.
