 “干洗”是怎么來的

如今我們都知道一些高級時裝要干洗才能保證它們始終光鮮亮麗，可你知道干洗是怎么來的嗎？干洗劑又都是些什么東西呢？
Like many inventions, dry cleaning came about by accident. In 1855, Jean Baptiste Jolly, a French dye-works owner, noticed that his table cloth became cleaner after his maid accidentally overturned a kerosene lamp on it. Operating through his dye-works company, Jolly offered a new service and called it "dry cleaning."
Early dry cleaners used a variety of solvents（溶劑）-- including gasoline and kerosene -- to clean clothes and fabrics. In the United States, the dry-cleaning industry is fairly new and has developed only during the past 75 years. Since World War II ended, the volatile（揮發性的） synthetic（合成的） solvents carbon tetrachloride（四氯化物）and trichlorethylene（三氯乙烯） gave way to a product known as perchlorethylene (perc四氯乙烯), which became the overwhelming solvent choice for the industry. It was not only safer and faster, but did a much better job of cleaning, required less massive equipment, less floor space, and could be installed in retail locations offering excellent quality one-hour service.
As a result of this innovation, the majority of clothes today are cleaned by perc. A proliferation of cleaning franchises and dry-cleaning businesses offering fast service from convenient, clean, and attractive locations evolved to change the industry into what we see today.
