Perchlorethylene. Great and terrible
It just so happened historically: all new solvents used in dry cleaning are compared with perchlorethylene. It has the highest cleaning power. PCE is the most studied organic solvent in the chemical industry. You could say a classic.
Once used in mechanical engineering as a parts degreaser, it has shown its effectiveness in cleaning and has served faithfully for a long time. PCE coped with the most difficult contaminants. He is subject to engine oil stains, ink, rust embedded in fabric ... and much more.
Competently organized production (when the entire process of processing clothes - cleaning, drying, wringing - is performed in a confined space) made the use of this solvent absolutely environmentally friendly.
Frankly speaking, ordinary household laundry with powder is much more harmful. However, the aggressive nature of this solvent made chemists look for an alternative. Along with the removal of the stain during the processing of PCE (especially on delicate fabrics), both color breakdown and damage to the tissue itself could occur.
But sooner or later everything ends. With the introduction of the organic solvent SENSENE on the market, the era of PCE has sunk into oblivion. The new solvent has an incredibly high cleaning ability, is delicate to things during processing and, of course, is environmentally friendly. These three factors allowed SENSENE to completely replace the ex-leader, significantly enriching the line of eco-solvents, and KIMS has become rightfully called an eco-cleaner that really cleans.
