Introduction and objective:
The appropriate selection of the type, composition and finish of textile materials under specific conditions of temperature and humidity influences the possibility of their microbial colonization. The aim of the study is to test the survivability of microorganisms on textile materials in different microclimate conditions.

Material and methods:
To test the survivability of bacteria (Staphylococcus aureus, Escherichia coli, Bacillus subtilis, and Streptomyces albus), virus (bacteriophage PhiX174), and fungi (Cladosporium cladosporioides, Aspergillus versicolor, and Penicillium melinii), five man-made (viscose) and synthetic (polyester, polypropylene, polyacrylonitrile, polyamide) fabrics made of homogeneous fibres (100% the same fibres), as well as five fabrics made of mixed fibres (i.e. polyester with addition of viscose, carbon, aramid, and anti-static fibres) kept in low (60%) humidity and at room (~24 °C) and elevated (~40 °C) temperature of the air were used.

Results:
The study showed different microbial survivability patterns. In the case of bacteria and bacteriophage, fibre admixtures added to synthetic materials usually reduced their survivability. In the case of fungi, synthetic, mainly polyester, as well as doped polyacrylonitrile and polyamide materials, supported the survivability of their conidia.

Conclusions:
Under specific microclimatic conditions, the textile material can be selected in a way that limits the survivability of harmful microorganisms, which may be deposited on it. And vice versa, by changing the microclimatic conditions when wearing clothes made of a specific fabric, one can ensure that the presence of microorganisms will be eliminated or at least their survivability will be significantly reduced.
