The many OH groups bind water, leading to swelling of the fabric and leading to wrinkling, which is minimized when these materials are treated with tetrachloroethylene and other dry cleaning solvents. Structure of cellulose, the main constituent of cotton.

This system ensures that only small amounts of PCE fumes are released at the end of the cycle. The majority of modern enclosed machines also incorporate a computer-controlled drying sensor, which automatically senses when all detectable traces of PCE have been removed. In enclosed machines, solvent recovered during the drying process is returned condensed and distilled, so it can be reused to clean further loads or safely disposed of. Much stricter controls on solvent emissions have ensured that all dry cleaning machines in the Western world are now fully enclosed, and no solvent fumes are vented to the atmosphere. This not only contributed to environmental contamination but also much potentially reusable PCE was lost to the atmosphere.

Machines of this era were described as vented their drying exhausts were expelled to the atmosphere, the same as many modern tumble-dryer exhausts. At this time, dry cleaning was carried out in two different machines-one for the cleaning process, and the second to remove the solvent from the garments.

A drop shop receives garments from customers, sends them to a large plant, and then has the cleaned garment returned to the shop for collection by the customer. Infrastructure ĭry cleaning businesses, from the perspective of the customer, are either plants or drop shops. Because it is stable, tetrachloroethylene is readily recycled. It has excellent cleaning power and is nonflammable and compatible with most garments. Shift to tetrachloroethylene īy the mid-1930s, the dry cleaning industry had adopted tetrachloroethylene (perchloroethylene), or PCE for short, as the solvent. These solvents were much less flammable than petroleum solvents and had improved cleaning power. After World War I, dry cleaners began using chlorinated solvents. The use of highly flammable petroleum solvents caused many fires and explosions, resulting in government regulation of dry cleaners. įlammability concerns led William Joseph Stoddard, a dry cleaner from Atlanta, to develop Stoddard solvent (white spirit) as a slightly less flammable alternative to gasoline-based solvents. He opened the first dry-cleaners in Paris in 1845. Jennings referred to his method as “dry scouring”.įrench dye-works operator Jean Baptiste Jolly developed his own method using kerosene and gasoline to clean fabrics. 6.5 Other solvents: niche, emerging, etc.ĭry cleaning originated with American entrepreneur Thomas L.She made the children clean up their own rooms.
