Laundry processes include washing (usually with water containing detergents or other chemicals), agitation, rinsing, drying, pressing (ironing), and folding. The washing will often be done at a temperature above room temperature to increase the activities of any chemicals used and the solubility of stains, and high temperatures kill micro-organisms that may be present on the fabric. Many professional laundry services are present in the market which offers at different price range.
Various chemicals may be used to increase the solvent power of water, such as the compounds in soaproot or yucca-root used by Native American tribes, or the ash lye (usually sodium hydroxide or potassium hydroxide) once widely used for soaking laundry in Europe. Soap, a compound made from lye and fat, is an ancient and common laundry aid. Modern washing machines typically use synthetic powdered or liquid laundry detergent in place of more traditional soap.
Cleaning or dry cleaning
Dry cleaning refers to any process which uses a chemical solvent other than water. The solvent used is typically tetrachloroethylene(perchloroethylene), which the industry calls “perc”. It is used to clean delicate fabrics that cannot withstand the rough and tumble of a washing machine and clothes dryer; it can also obviate labor-intensive hand washing.
