Sažetak
In the early stages of the development of dry-cleaning methods, environment protection was an issue of no concern. By the end of the 19th century, soap products were introduced into gasoline solvents in order to improve the bath conductivity and reduce electrostatic charge in the cleaned textiles and the associated risk of fire. The cleaning efficiency was also improved. In the 20th century halogenated inflammable solvents were introduced. All but perchlorethylene were withdrawn and banned on account of their high toxicity. The 1960s witnessed the beginnings of a growing environmental awareness, while the 1990s most decidedly made environment protection a crucial focus of interest. Only new non-toxic solvents remained in use, while the use of PER was highly restricted. Its weight must not exceed 2% of the weight of the cleaned textiles.
