The invention relates to a process for textile cleaning and disinfection by means of plasma and plasma lock for inactivating viruses, bacteria and spores and also for purifying air in the conventional sense, such as to remove dust, pollen, odours or the like. The object of the invention is to develop a process for cleaning and disinfection of textiles and air to remove viruses, bacteria, spores and also for cleaning to remove dust, pollen, odours etc., in which the use of water and diverse cleaning agents and also disinfectants is not necessary, or can be significantly reduced. In the lock, living creatures must be able to be detained - likewise, individual items, textiles etc. must be able to be treated. In this case, airborne aerosols (droplets, particles, dust) and also aerosols or microbes adhering to the clothing or the body or the product must be able to be treated. The basic principle should also be generally applicable to rooms (e.g. waiting rooms) or animal housing and also under clean room conditions. According to the invention, cleaning of, e.g., odour-polluted clothing and also the sterilization of textiles proceeds on the basis of plasma processes. In this case, the following process steps are used: a) plasma generation, b) ozone generation and activation, c) sterilization, d) oxidation and destruction of gaseous components, e) separation of microbes and aerosols and f) destruction thereof.
