Fig. 28 Neutralisation chamber
Neutralization Compartment
This compartment neutralizes the fabric pH by automatic acid dosing system.
This compartment is equipped with pH monitoring probe to measure actual pH
of liquor and control amount of acid dosing linearly by adjusting strokes of acid
dosing pump. The liquor is continuously circulated by circulation pump to achieve
pH consistency.
2.5.7 Vertical Drying Range
It consists of stacks of large diameter drying cylinders arranged in vertical manner
to dry the fabric. Drying range are equipped with automatic moisture controller
to maintain required moisture content in the fabric being processed by controlling
temperature of drying cylinders precisely with the help of proportionate control valve
(Fig. 29).
2.5.8 Fabric Delivery
The fabric delivery serves to wind fabric onto a batch after processing. During
continuous operation, the fabric delivery with chute allows fabric changes to take
place without stopping the machine, and thus delivers the optimum production result
(Fig. 30).
