Dry cleaning

Dry cleaning

The dry cleaning process begins with identifying the stain. The garment is then placed in the dry cleaning machine, where the cleaning product (perchlorethylene) acts as a solvent. This product, being volatile, helps the garment to come out already dry, without any alteration of colors or textures. Dry cleaning machines appeared in Spain in the 1940s and since then it has been developed in two clear senses, make them a closed circuit that does not produce emissions to the environment and improve the quality of the solvent medium to improve the quality of the wash. Currently a dry cleaning machine consists of two or three tanks, a wash drum, a still, filters, drying chamber, water separator, soap pumps, waste water recovery systems, and a computer that controls everything.
There are various cleaning systems, but we can assert that currently the most widely used system is the two-phase washing system with continuous distillation, namely: First bath, prewash This first bath is the one that receives the highest load of dirt since it is the first one that wets the clothes dissolving all the fats, oils, and environmental pollution, after the minutes of washing this bath is sent to the distiller where it is heated and when it reaches above 125º it becomes steam and it passes through a coil that it cools it, to end up in a separator that separates the water from the clean and pure peru. Centrifugation The laundry is centrifuged at high speed until the solvent is almost completely extracted. Second washing bath This second bath of clean solvent will be reinforced by the addition of soaps that can fulfill different functions with greater or lesser success, such as, reinforcing the washing, bleaching, antistatic, bactericidal, deodorant, anti-lint, softeners, waterproofing, fire retardants, depending on the type of textile we are treating. This second loaded bath, after cleaning, will become the first bath of the next laundry machine, so the last bath is always made with totally clean liquid and the first is always loaded with soap, thus increasing its power of cleaning. Centrifugation The laundry is centrifuged at high speed until the solvent is almost completely extracted. Drying and deodorizing The clothes are dried at medium temperatures of 50-55º maximum until they are completely dry free of solvent. The duration of drying is controlled by an automatic system that determines the duration of this phase in proportion to the quantity and type of garments introduced into the machine. Then deodorization is carried out to eliminate the small particles of solvent that may remain on the clothes when drying is finished. Opening the machine After a short safety time, the door is released and can be opened to remove the clean clothes.The stains that remain after this process have very little chance of being removed, but if the fabric allows it, a normal procedure is attempted. new manual spotting and a second dry cleaning, then the garments are ironed and bagged for delivery. Check which is the cleaning system of your dry cleaner, look at the solvent deposits, they are next to the floor in dry cleaning machines, if the solvent in more than one deposit is not clean and transparent, your dry cleaner does not use the cleaning system. continuous distillation, let us at least trust that the service is really ... economical, since it is not of quality Source: http://www.guia.tintorerias.com Copyright © 2013 Guía de Tintorerias y Lavanderias
