Humidity Or Hawa Pani

When I started my career with a spinning mill, I found it interesting, when the shift in-charge would call the in-charge for Hawa Pani ( Humidity )

The lack of right humidity would cause a havoc in spinning. Ends breaking in spinning, simplex running a muck, drawing roller lapping and carding loading etc etc.

Humidity is a major cost center in spinning. A power guzzler and a necessary evil. But again like everything else in Textiles, Humidity and its controls have remained basically unchanged in the last 100 years.

If Hand phones merged a Camera and a FM radio and Internet on a small device, then the message was that it only needs some lateral thinking to get other accessories merged into the basic machine.

There was no reason that the Humidification could have not been localized on the machine itself and not a large separate plant eating away so much of power.

The integrated machine would have a small fan and a water dehumidifier sitting right on the top of it. Thereby ensuring that the fiber gets enough humidity as desired and fully controllable on the user machine.

While for Ring Frames and Simplex could still have a split conditioning wherein the machine frame has a duct running across the machine and enough dehumidifier points.

This also avoids the use of outside air, which normally is a source of blackening of the yarn.

The air change would be managed with suction fans etc.

The investment into humidity plant runs into few hundred thousand dollars and the operational cost is a drain on profitability.
