What is humidification and why it plays key role in cotton industry?
• Humidification simply means water vapour present in the air.
• Cotton having hygroscopic property.
• Humidification region has directly impact on the weight of the textile.

PHYSICAL PROPERTIES OF COTTON
• HYGROSCOPIC NATURE:- Absorb moisture from surrounding environment
• ELASTIC PLASTIC NATURE:- Crystalline polymer system
• Tenacity:- Strength of cotton fibres

TYPES OF HUMIDITY
• SPECIFIC HUMIDITY SH=mH2O÷mnet
• RELATIVE HUMIDITY
RH=PH2O÷P*H2O
Example: - A sample of air at 10 degree centigrade can hold less moisture than the same sample of air at 20 degree centigrade.

TEMPERATURES FOR HUMIDIFICATION PLANT
• DRY BULB TEMPERATURE(Tdb)
• WET BULB TEMPERATURE(Twb)
• DEW POINT TEMPERATURE(Tdp)i. If dew point temperature is closer to the dry air temperature-the
relative humidity is high.ii. If dew point temperature is well below the dry air temperature-
the relative humidity is low.

TYPES OF AIR COMPRESSORS
SCREW COMPRESSOR
Pros: Noise restrictions Low maintenance cost Few moving parts
Cons : Short life Chance of air leakage Limited presser developed
![Page 12: Major training report power point](https://reader036.vdocuments.us/reader036/viewer/2022062523/587239cc1a28ab102f8b5f0d/html5/thumbnails/12.jpg)
RECIPROCATING COMPRESSOR
Pros:Comparatively cheap
Easy to maintained
Available to high presser
Cons: Very humming
High outlet temperature
Many moving parts
![Page 13: Major training report power point](https://reader036.vdocuments.us/reader036/viewer/2022062523/587239cc1a28ab102f8b5f0d/html5/thumbnails/13.jpg)
ROTARY CENTRIFUGAL COMPRESSOR
Pros Actually very quite High efficiencies High presser can achieve
Cons Relatively high cost Compressed air is very hot Complicated monitoring
