Biodegradation of cellulose fibres could be successfully decreased with the chemical finishing, where the sol-gel technology is of great importance. In this study, the differences between the active and passive antimicrobial protection are discussed. While the active antimicrobial activity is assured with the application of antimicrobial agents, the passive one is caused by the presence of repellent and easy-care agents which decrease the surface free energy of fibres and crosslink the fibres amorphous regions. This minimizes adhesion of microbes and hinders their penetration into the fibres.

The research work deals with biodegradation of textile fibres and their antimicrobial protection. Conventional and modern antimicrobial agents, their chemical structures and mechanisms of activity are presented. Different microbiological methods for determination of agent’s antimicrobial activity are described. Comparison between antimicrobial efficiency of two agents was presented, i.e. the sol-gel precursor with quaternary ammonium group which forms the bio-barrier on the fibres and silver chloride bounded to the sol-gel matrix which acts by the controlled release mechanism.
