If the traditional washing method is used, not only can't clean and maintain the clothing, but also will destroy the clothing fibers, dirty clothing. In addition, during the baling and handling process, there is a risk of dust and microorganisms. Therefore, when cleaning clean clothes, pharmaceutical enterprises need to use certified professional and technical personnel in accordance with the standards and requirements of standardized cleaning and purification, such as: How much water temperature should be cleaned, how many times should be cleaned and rinsed, what kind of water should be selected during cleaning, what proportion of detergent should be added, how to do the test, the test standard and so on. Incorrect cleaning will lead to the serious attenuation of the anti-static and dust-free performance of the purification suit, and destroy the cleanliness of the dust-free workshop, thus affecting the quality of the product. For the cleaning of clean clothes, Special attention should be paid to the following:

 

1: When cleaning, special professional cleaning and drying equipment must be used, rather than industrial washing machines; Clean clothes can be cleaned by stainless steel channel type dust-free special washing machine and clothes dryer, and the air used for drying is filtered by the filter of clean air.

 

2: The cleaning agent used for cleaning clean clothes should be non-ionic surfactant, PH value is neutral, in order to ensure the performance and service life of the purification clothes; Do not mix with other clothes when washing. Use hand washing or soft washing machine.

 

3: The cleaning environment must be cleaned in the purification room in line with its cleanliness. After the completion of cleaning, the drying, packaging and inspection should be carried out in the clean room environment of at least the same grade or even higher than the use environment.

 

4: Generally speaking, the cleaning process of clean clothes uses treated sand filter water and pure water, and the rinsing process uses deionized water with a resistivity of at least 10 megohm/cm; The cleaning water for clean clothes in dust-free purification workshop must be ultra-pure water, rather than ordinary industrial water.

 

Of course, if you can ensure that the particles on the washed clothes are at a low enough level, you can ensure a low level of microbes on the other side (microbes are mostly attached to the particles, in the form of particles).
