3. What is Air Pollution?
Air pollution is the introduction of
chemicals, particulate, or
biological material that cause
harm or discomfort to humans or
other living organisms, or
damages the natural environment
into the atmosphere.
4. Categories of Air Pollution
Air pollution is categorized by the
emissions
Carbon di oxide
Aerosol fumes and gases
Toxic gases
Smoke and
Dust
5. Air Pollution In Textile Industry:
Textile industry is one of the major source in
the increase of air pollution globally in general
or in developing countries in particular.
The textile industry is plagued by air pollution
problems which must be resolved. In
particular, smoke and odor arising in the
process require abatement.
Air pollution control technology is available
today which will serve the textile industry well.
7. Pollutant Particles : Comes
From:
Oil mist, visible Knitting, lubricating
plume and organic oils, heat processes,
particles. calendaring drying
and curing.
Carbonization of
Acid mist wool and spray
dyeing…
Natural and
Dust and Lint synthetic fibers
spinning.

9. Major Air Pollution In Textile:
The major air pollution problem in the textile
industry occurs during the finishing stages,
where various processes are employed for
coating the fabrics.
Coating materials include lubricating oils,
plasticizers, paints and water repellent
chemicals essentially, organic compounds.
such as: oils, waxes or solvents.
10. In the textile Air pollution problem is also done
by the creation of VOCs (volatile organic
compounds), which take the form of visible
and invisible smoke but above all an
objectionable odor.
11. Necessary steps to Control it:
It controlled by installing any suitable APC
methods, because a variety of APC methods
are available.
Wet ESP (electro static precipitators)
Scrubber,
Dry ESP (electro static precipitators) fiber filter
12. Pollution Control in Spinning mill
by:
Maintaining m/c parts
Maintaining hardness of rubber
cots
Maintaining RH%
Cyclone filters, Cloth filters
13. Pollution Control in Wet
processing unit by:
Electrostatic precipitator
Scrubber
Oxidizer
14. General control:
1. Height of
chimneys:
should not be
less than 30
meters.
