Model: Color Soft HTHP - Soft Flow Fabric Dyeing Machine

Knitted fabric is almost always dyed in batch process. The commonly heard
term is a soft-flow machine, which indicates the gentle treatment that the
fabric gets in such a process. This gentle treatment is essential to minimize
fabric distortion. Evenness of dyeing exhaustion and fixation are primarily
determined by the control of dyeing conditions (liquor ratio, temperature
/gradient, dosing curve, process parameters).These features should be controlled
automatically. We utilize control systems from reputed suppliers in this field
to achieve a high degree of automation and central. Another parameter, which
determines evenness and exhaustion, is the speed of the fabric. The higher the
speed, the more even dyeing and quicker the exhaustion.

The fabric is propelled by the lifter reel (winch) which should be driven by
a frequency controlled motor to control the speed. The liquor is circulated by
means of a pump driven by a frequency controlled motor in order to control
liquor flow. Measurement of actual fabric speed and synchronization with winch
speed and liquor flow is of absolutes importance for low tension, no slippage
and ultra gentle fabric transport. Fabric speed to be maintained is determined
weight per unit length of fabric and type of dyestuff. The movement of every
fabric rope should be monitored and compared to the monitored and compared to
the minimum set point. This provision enables even dyeing, low tension in
fabric, detects tangles before they are firmed.

The nozzle design and liquor flow is very critical in ensuring low tension on
the fabric and absence of abrasion. This assumes more importance when dyeing
delicate fabrics.
