英文阅读：“干洗”是怎么来的
如今我们都知道一些高级时装要干洗才能保证它们始终光鲜亮丽，可你知道干洗是怎么来的吗?干洗剂又都是些什么东西呢?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(溶剂)-- 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(挥发性的) 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.
