How does bleach hurt linen?

1. Selection of washing materials: generally use washing powder, bleach, softener, neutralizer and emulsifier (of course, the washing liquid is better, there is no residue, which prolongs the service life of hotel linen, and hotel linen is not easy to turn gray and yellow).

2. Conventional washing methods: Washing powder, bleaching agent (bleaching agent, hydrogen peroxide), softener (towel) and neutralizer (neutralizing the alkalinity of washing powder and bleaching) are much better than cold water washing. If there is a lot of oil, add emulsifier, and a small amount is enough.

3. Washing temperature: Generally speaking, the washing temperature of hotel linen should reach about 60-70 degrees. If the temperature is low, the washing effect can not be achieved, and the effects of decontamination, sterilization and bleaching can not be achieved.

4. Washing method: It is mainly composed of mechanical force, water temperature and washing time, reaching the washing standard. In addition to cleaning the residual stains on hotel linen, it also has the function of sterilization and disinfection. Because the sheets used by others have no strict washing procedures, it is easy to infect germs, so hotel linen that comes into direct contact with the skin must be disinfected at high temperature.

Service life of hotel linen: Strictly speaking, hotel linen has a service life. Cotton sheets and pillowcases, washing times 130~ 150 times; Blending (35% cotton), washing times 180~220 times; Towels, washing times 100~ 1 10 times; Table cloth, washing times 120~ 130 times.

Within the specified range of washing times, whether it is high temperature or low temperature, it will reach this number, that is to say, it will not damage the hotel linen, but the highest temperature should be controlled at about 70-75 degrees, so that the temperature can meet the requirements of washing and disinfection (some washing materials are ineffective at low temperature) and achieve the washing effect.

Because the temperature of cold water washing is not enough, some stains are not easy to clean, and the washing time can only be prolonged. At the same time, washing depends on mechanical force, and mechanical friction will also damage hotel linen, so it is not recommended to wash with cold water.
