Question 1: About the issue of using dry cleaning or water washing for clothes
Choosing dry cleaning or water washing is not about which method is more upscale, but about selecting the washing method that is more suitable based on the fabric, stains, and decorations of the clothes. In fact, in formal laundries that meet national standards, the cost of water washing is not lower than dry cleaning. In laundries in our country, water washing accounts for about 50% of the total washing business, while in developed countries in Europe and America it can exceed 60%.
Simply put: clothes suitable for dry cleaning mainly include suits, formal dresses, silk fabrics, wool, cashmere, fur, etc. Clothes suitable for water washing mainly include ordinary shirts, down jackets, artificial leather, fine cotton fabrics, clothes with elastic bands, synthetic fibers (polyester, nylon, etc.), and clothes with special decorations.
Question 2: About the issue of tetrachloroethylene as a dry cleaning solvent
Dry cleaning is a washing method that uses organic solvents (tetrachloroethylene, hydrocarbon solvents, etc.) to clean clothes and remove oil stains or dirt in a dry-to-dry process. The advantage of dry cleaning is that it is effective in removing oily stains on clothes, maintains shape well, does not fade, and can also sterilize and prevent moth damage.
Tetrachloroethylene is the most commonly used dry cleaning agent internationally. Due to its good stain removal performance and safety, currently more than 80% of dry cleaning machines worldwide (including developed countries in Europe and America) use tetrachloroethylene as the cleaning agent. The claim that tetrachloroethylene has been banned as a dry cleaning agent in the United States for many years is unfounded.
Tetrachloroethylene is an organic solvent with certain toxicity and strong volatility. Standard laundries use fully enclosed dry cleaning machines to wash clothes, which involve processes such as distillation, drying, and recovery. Afterwards, clothes are also ironed and shaped at high temperatures, so there will be no tetrachloroethylene residue on the cleaned clothes. Just like in paper making, leather production, grain, vegetables, etc., certain amounts of toxic substances are involved during production, planting, and processing, the key is whether the final product meets all quality standards.
Question 3: About the use of detergents (washing powder, soap) and brushing clothes
The washing and dyeing industry strictly prohibits the use of unqualified detergents. Washing powders, soaps, detergents, auxiliaries, and stain removers produced by formal manufacturers are routine supplies in washing and dyeing enterprises and can be used. Laundry technicians should use detergents, auxiliaries, and stain removers reasonably according to the contamination of the clothes.
Brushing is a common washing operation in the washing and dyeing industry, but it should be strictly performed according to the "three flat and one even" method (i.e., flat washing board, flat clothes laying, flat brush movement, and even force) to ensure stain removal without damaging the fabric structure.
Question 4: About the cost of washing and the issue of "excessive profits"
The laundry industry is a fully competitive industry and does not have so-called profits exceeding ten times the cost.
The washing cost of a standard laundry shop, besides rent, personnel fees, and various insurances, as well as washing solvents and chemical auxiliary materials, more importantly includes equipment purchase, maintenance, and professional renovation costs of the laundry shop.
To regulate industry charging standards, the Washing and Dyeing Professional Committee conducts regular annual laundry price surveys, publicly discloses the charging range and national average price for clothes, so consumers understand the consumption. Laundry shops must clearly display laundry prices in the store and advocate bargaining and value-preserving washing for high-end clothes (luxury goods).
