VOYAGE OF SOFT FLOW DYEING MACHINE

Modern Soft Airflow Dyeing Machine

Heat of Softflow dyeing Machine

RU FABRIC LIFTING SYSTEM Rotated U fabric lifting system. Minimizes slippage b/w fabric lifter

reel to produce a good fabric surfacefinish.

Lifter reel provides all the liftingpower needed to ensure the fabric inrunning at approximately the samespeed as the fabric.

In addition, the guide roller enablesthe fabric to be transported into thenozzles in the most orderly manner.

DELICATE JET NOZZLE

Designed for the most gentlefabric treatment and optimumdyestuff fabric interchange.

The nozzle provides better liquidpenetration into the fabricmaterial where the fabric iscompletely immerse in liquid.

This allow the fabric to floatthrough the nozzle tube in a veryrelaxed condition and thereduced pilling effect.

TWINFLOW CONCEPT

World wide patented fabric transport and storage system. TSF enhance the fabric transport efficiency at lower water pressure…? To achieve this water flow rate is equally distributed b/w the two

overflow outlets.

CONTD…

As a result, the actual water pressure on the fabric is approximately ¼ forthe same given speed on a single flow nozzle.

Achieved by the fabric coming into contact with the liquor at the twodifferent point along its path assisting in the fabric movement.

The natural deceleration of the fabric after its exit from the first overflow is eliminated as the fabric reaches the second flow.

This is the reason how the higher fabric transport rate can be achieved through lower water pressure.

This leads to significant reduction in the mechanical abrasion.

CONTD…

100% increase in fabric to liquor exchange. Safer dyeing condition & reduced dyeing time. Low liquor dyeing without compromise with fabric quality.

UPPER TANGLING RELEASED DEVICE

When there is upper tangling thedevice will immediately stop thecirculation pump and lifter reel willreverse its direction until the fabrictangling is released.

With this automation device in mostcircumstances the machine operatorcan solve the tangling problemwithout having to open the servicedoor or to manually operate anycontrol botton.

LIQUID SEPARATING AND FABRIC PLAITING DEVICE

The SEPLA system consists of afabric conplaiter which enables thedye liquid be separated from thefabric and returned to the circulationsystem.

It improves the bath turnover rateand leads to an even color shade.

Since, only a minimal dye liquid willenter the storage chamber, it willhelp to avoid the fabric pilling andalso increase the batch capacity.

ELBOW PLAITING SYSTEM

Correct storage of fabric is one of the most important element in reducing tension and creasing of the fabric.

Ensuring smooth, tangle free operation throughout the dye cycle. Unique plaiting system has been developed and patented. Perfect storage of the fabric utilizing entire width of the box. Eliminates blind spot.

LIQUOR BY-PASS SYSTEM

Automatic surplus liquor by-pass. Channel the liquid away from the

box. Prevent affecting the orderly

storage of the fabric.

SPEED SYSTEM

The fabric speed in fabric lifting system and fabric plaiting speed are synchronized to ensure and orderly fabric plaiting across the full width of the storage chamber to maximize the batch capacity while reducing the chance of fabric tangling.

Frequency controlled winch drive

Special blower for fabric drive

Service temperatur 140°C

Reduction of proces time by 25%.

SPECIAL FEATURES1 Safe fabric trans­port, optimum displacement

and little crease formation are ensured by the aerodynamic drive.

2 By means of the active fabric run con­trol a slip regulation is possible, facilitating the exact monitoring of fabric speed and the best possible fabric handling.

3 The unique rinsing method by spraying fresh water allows short processing times with best rinsing effect.

CONTD…5 Optimized fabric smooth plaiterensures an excellent displace­mentof the fabric.

6 Combined PTFE slide bottomconsists of foil and sliding rods forthe best careful treatment of fabricsurface and a smooth transport inthe storage chamber.
