kemtvätten

Kemtvätten, also known as dry cleaning, is a method of cleaning clothes and textiles that uses chemical solvents rather than water. This process is particularly effective for delicate fabrics that could be damaged by traditional water-based washing, such as silk, wool, and rayon. The solvents used in dry cleaning can dissolve oils and greases that water alone cannot, making it a powerful cleaning method for stubborn stains.

The dry cleaning process typically involves immersing the garments in a solvent, such as perchloroethylene (perc), in a specialized machine. The machine agitates the clothes, allowing the solvent to penetrate the fabric and lift dirt and stains. After the cleaning cycle, the solvent is distilled and filtered to be reused, minimizing waste. The garments are then spun to remove excess solvent and finally dried, often in a tumbling process.

While often referred to as "dry" cleaning, a small amount of liquid is used in the process. The term "dry" refers to the absence of water. The solvents used are carefully selected based on the type of fabric and stain to ensure effective cleaning without causing damage. Professional dry cleaners have the expertise and equipment to handle a wide range of textiles and stains, preserving the quality and longevity of garments. However, concerns about the environmental impact and potential health effects of some solvents have led to the development of alternative, more environmentally friendly dry cleaning methods.
