INTRODUCTION Nowadays, biological pathogens from hospitals are considered as great issues for human health. In order to protect the patients against these bacteria, new protective mechanisms are particularly needed 1. Masks and protective clothing usually made of coal particles or plastics but have disadvantages considering their inability to eliminate the pathogens and inefficiency to exchange body evaporations along 1,2. Applications of nanofibers in elimination of pollution are drastically emerging. Having extremely high surface to volume ratio, nanofibers are able to carry out highly efficient chemical reactions to eliminate microbial pathogens. So the nanofibers filters are capable of neutralizing biological pathogens with no reduction in air and water vapour permeability 2,3. A layer of electrospined nanofibers have too many pores while the dimensions of the cavities are in the nano range. Containing such nano sized holes; nanofibers have very good resistance against passage of harmful environmental bacteria. Furthermore, nanofibers are capable of performing chemical reactions in order to destroy pathogens 3. N,N-Dichloropolystyrene sulfonamide nanofibers can create and release active chlorine (HOCl) into environment. Hypochlorite acid (HOCl) hydrolyzes the peptide chain and causes loss of cell membrane of bacteria 4. After penetration
