- Abstract
Nowadays dry cleaning is used for all types of garments. The most common dry cleaning solvent at present is perchloroethylene (perc). There are several health risks associated with perc. The use of perc is already strictly regulated and more strict regulations are expected. In search of other environment friendly solution carbon dioxide is a viable alternative for pert. Carbon dioxide (CO2)is non-toxic, inflammable and ecologically sound. Liquid and supercritical CO2 can be used. The use of supercritical CO2 offers several new possibilities, which makes the use of CO2 more attractive. CO2 is non-toxic, non-polluting medium which eliminates zoning restrictions, flammability risks and harmful threats to individuals and the environment. CO2 cleans virtually every type of fabric and provides longer garment life, brighter colours and is entirely odour free. The capital requirement of the CO2the long run, these machines will save money by eliminating the disposal and regulatory costs associated with perc. The overall costs of liquid CO2 dry cleaning are lower than those of perc dry cleaning.
