Put the pretreated clothes into a dry cleaning machine, wash them with dry cleaning solvent, and spin (dry) them for post-treatment. The main purpose is to remove the residual dry cleaning solvent and iron and shape it.
Extended data:
Dry cleaning originated in Paris, France at the beginning of 19 century. Legend has it that a Frenchman named Jean-Jolly owns a dyeing and weaving factory in Paris. One day, a worker in the factory accidentally knocked over an oil lamp on the table, which made the tablecloth on the table wet.
After the tablecloth dried, Jolly was surprised to find that the place on the dirty tablecloth that had been wetted by lamp oil was obviously cleaner than other places, so he went back to find out the lamp oil, which turned out to be something called terpene.
Therefore, Jolly came to the conclusion that this substance has a cleaning function, and that some solvents can be used to remove some oil stains that cannot be washed with water in the anhydrous washing process, and then it can be developed and applied in its factory.
