What is the process of dry cleaning by petrol is thre any machine used?
Drycleaning is a process that cleans the clothes without water. Petrol or perchloroethylene abbreviated "perc" is used.
The steps involved in this process are:
- Garments are placed into a washing chamber of dry-cleaning machine
- The washing chamber contains a drum and shell. The shell holds the solvent petrol while the rotating drum holds the clothes.
- The solvent is passed through a filtration chamber and then fed back. This is called washing cycle
- At the end of the wash cycle, the machine starts a rinse cycle
- After the rinse cycle, the machine begins the extraction process, which recovers dry-cleaning solvent for reuse.
- Then, machine starts the drying cycle followed by aeration cycle.
- Finally, the garments are clean and ready for pressing/finishing.
ANS: Dry cleaning is any cleaning process for clothing and textiles using a chemical solvent other than water. The solvent used is typically tetrachloroethylene (perchloroethylene), abbreviated "perc" in the industry and "dry-cleaning fluid" by the public. It is often used instead of hand washing delicate fabrics, which can be excessively laborious. Modern dry cleaning uses non-water-based solvents to remove soil and stains from clothes. The potential for using petroleum-based solvents in this manner was discovered in the mid-19th century by French dye-works owner Jean Baptiste Jolly, who noticed that his tablecloth became cleaner after his maid spilled kerosene on it. He subsequently developed a service cleaning people's clothes in this manner, which became known as "nettoyage à sec," or "dry cleaning.
