6. RU FABRIC LIFTING SYSTEM
 Rotated U fabric lifting system.
 Minimizes slippage b/w fabric lifter
reel to produce a good fabric surface
finish.
 Lifter reel provides all the lifting
power needed to ensure the fabric in
running at approximately the same
speed as the fabric.
 In addition, the guide roller enables
the fabric to be transported into the
nozzles in the most orderly manner.

7. DELICATE JET NOZZLE
 Designed for the most gentle
fabric treatment and optimum
dyestuff fabric interchange.
 The nozzle provides better liquid
penetration into the fabric
material where the fabric is
completely immerse in liquid.
 This allow the fabric to float
through the nozzle tube in a very
relaxed condition and the
reduced pilling effect.

8. 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.

9. CONTD…
 As a result, the actual water pressure on the fabric is approximately ¼ for
the same given speed on a single flow nozzle.
 Achieved by the fabric coming into contact with the liquor at the two
different 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.

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

11. UPPER TANGLING RELEASED DEVICE
 When there is upper tangling the
device will immediately stop the
circulation pump and lifter reel will
reverse its direction until the fabric
tangling is released.
 With this automation device in most
circumstances the machine operator
can solve the tangling problem
without having to open the service
door or to manually operate any
control botton.

12. LIQUID SEPARATING AND FABRIC PLAITING DEVICE
 The SEPLA system consists of a
fabric conplaiter which enables the
dye liquid be separated from the
fabric and returned to the circulation
system.
 It improves the bath turnover rate
and leads to an even color shade.
 Since, only a minimal dye liquid will
enter the storage chamber, it will
help to avoid the fabric pilling and
also increase the batch capacity.

13. 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.

14. LIQUOR BY-PASS SYSTEM
 Automatic surplus liquor by-pass.
 Channel the liquid away from the
box.
 Prevent affecting the orderly
storage of the fabric.

15. 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.
