Abstract

Cellulosic textile fibres are biodegradable. The result of biodeterioration of cellulosic fibres is a reduction of the polymerization degree and thus a textile strength loss. The risk for microbiogenous decay of such textiles is linked to humidity and therefore to the corresponding range of application. Cellulosic clothing and furnishings may suffer from humid storage conditions. Awnings, covers and tarpaulins need protection by technical antimicrobials, when moisture is present. Biodegradable geotextiles can be used for plantations on steep slopes against erosion. Microbiological tests can be divided into in-use-conditions, close to the practice tests (e.g. soil burial test, saturated atmosphere test) and in-vitro tests (tests on agar). Some results of soil burial tests, fungus resistance tests and bacteria resistance tests are presented.
