Comparison between washing and dry cleaning: The washing methods of clothes are mainly divided into washing and dry cleaning. Whether clothes are washed or dry-cleaned, we should follow the following principles: under the premise of ensuring that fibers and colors have no influence, wash away the dirt on the surface of fabrics. Therefore, the laundry staff must be clear that not all clothes can be dry-cleaned and not all clothes can be washed. Then some clothes can be dry-cleaned and washed. Choose according to the characteristics of dry cleaning and water washing.
Advantages of washing: Compared with dry cleaning, the advantages of washing mainly include three aspects: First, the cost of washing is low. Water washing takes water as the main raw material, and some detergents are added in the washing process, while dry cleaning uses and consumes dry cleaning agents such as tetrachloroethylene and petroleum solvent. In contrast, a ton of water is several yuan, and a kilogram of dry cleaning agent is several yuan. Second, the cleaning power of water washing is high. The wetting effect of water itself is not as good as that of dry cleaning agent, but it has strong solubility and can be dissolved in various detergents with surfactants as the main component. In the washing process, it plays the role of wetting, emulsifying and foaming, and has good decontamination ability. But the dry cleaning agent can only be dissolved in a small amount of surfactant. Third, washing is the most environmentally friendly. Nowadays, green laundry is advocated, and water washing, a recognized ecological washing, is the most environmentally friendly compared with dry cleaning. Compared with the old dry-cleaning machine, some pollution indexes of both the oil-contaminated dry-cleaning machine and the fully-enclosed tetrachloroethylene dry-cleaning machine are reduced, because both oil-contaminated and tetrachloroethylene are organic solvents, which have an impact on the environment and human body.
Features of dry cleaning: The advantage of dry cleaning is that you can wash some clothes that can't be washed. Mainly reflected in dry cleaning clothes, do not shrink, do not fade, do not bubble, do not deform. For some clothing made of protein fiber and viscose fiber, it will shrink seriously when washed, resulting in a smaller appearance after washing. The color of clothes is mostly dyed with some water-soluble dyes at high temperature. So it's easy to fade when washing. Dry cleaning agent is insoluble in water and is not easy to shrink and fade in dry cleaning of clothes. Some coats have molded rubber linings. If washed with water, rubber contains some water-soluble resin, which will lead to degumming and foaming of clothes after washing.
