Cleanroom: Purity of the air, surfaces and clothing
Cleanrooms are required in far more sectors than many people would initially assume: in the pharmaceutical and medical industries, for biosciences, in the research and production of foodstuffs as well as for the production of semiconductors and in nanotechnology. As the name suggests, these are rooms in which very particular cleanliness rules and hygiene regulations apply. After all, cleanrooms must provide a particularly clean environment to prevent products from being contaminated or research results from being corrupted. This means the concentration of particles in the air and on surfaces must be measured regularly and, in addition, the amount of germs on personnel must also be controlled.
Cleanroom clothing assumes a protective function
The staff who work in cleanrooms present the greatest source of hazards. It is they who bring the outside world into the cleanroom and, in turn, to the products via particles which adhere, for example, to the skin, hair and body as well as via bacteria and germs which live on the body or which are exhaled.
Cleanroom clothing thus performs an important protective function: it acts as a barrier between the person and cleanroom product. The textiles have to satisfy certain specific requirements. Take the material for example: the material must be woven in such a way that it retains particles from the carrier and does not shed fibres into the outside world. This enables a cleanroom suit to function as a buffer.
