Dry cleaning
is any cleaning process for clothing and textiles using an organic solvent
other than water generally known as dry cleaning fluid, and typically this
is tetrachloroethylene
-
Dry cleaning
is necessary for cleaning items which would otherwise be damaged by water
and soap or detergent and it may also be sought if washing by hand.
- The dry cleaning
process is a process for removing dirt, stain, soil, etc. on textile
products with organic solvents and detergents.
Process
- Dry cleaning is any
cleaning process for clothing and textiles using an organic solvent
other than water. Dry cleaning is necessary for cleaning items which
would otherwise be damaged by water and detergent.
- During the
dry-cleaning process, garments are immersed in a type of liquid that
causes the fabric to become wet but does not saturate or damage the
fibers of the cloth. During this process, the fibers remain in their
original state without water saturation, which reduces or eliminates
damage to dyes and fibers.
- The Perc Dry Cleaning
process shows: Perc and a small amount of detergent are added to the
materials and then agitated, Materials are spun to recover excess perc,
Materials are tumble dried in heated air, Cool air is used to remove any
residual solvent within the drum and to reduce the temperature of the
materials.
Technology
-
The Dry Cleaning Project is an
excellent illustration of industrial ecology because, although it
started out dealing with the issue of environmental and worker exposures
to perchloroethylene (perc), we now have new technologies that are
coming forward and we've even changed the people that are participating
in the process.
-
Densified Fluid Cleaning (DFC) is
a dry source, liquid mode cleaning technology. It is based on
application of densified gases at elevated pressures and low
temperatures. When used together with microwave downstream plasma
treatments, DFC enables the damagefree removal of heavy post etch
residues, containing Al, Ti or Cu, not readily affected by other wafer
cleaning methods.
-
The CO2 Cleaning Process is a
carbon dioxide-based garment cleaning process that has been developed
for use by commercial and retail dry cleaners.
Report
-
The new regulations and
dry-cleaning processes have prompted a new crop of dry-cleaning
start-ups that provide a more environmentally-friendly approach to
dry-cleaning. The trend for U.S. consumers to spend less on dry-cleaning
because of environmental concerns and changes in workplace dress will
continue to impact the dry-cleaning industry.
-
Pakistan the seventh most populous
country in the world. This growth rate has increased the demand for
various products and services, and one of the services is the proposed
business. People in big cities are now inclined to use more
sophisticated measures to cleaning their clothes. These people range
from middle class to upper class.
-
The drycleaning industry is very
fragmented. The International Fabricare Institute reports that
approximately 30,000 dry-cleaning businesses currently operate in the
U.S. today, employing 200,000 people.
