abstract


Work is devoted to creation of the biostable, fatfree sizing composition IS-2 for chemical fibers.

The aim is to ensure long-term protective effect of chemical fibers from the mold defeat.

The study of behavior of micromycete growth which belong to different species in medium of Czapek-Dox with 1 % of sizing composition IS-2 as the sole carbon source showed that there are components in the sizing that can serve as nutrient substrate for the development of fungi Aspergillus niger, aureobasidium pullulance, penicillium chrysogenum, Trichoderma viride.

When choosing a fungicide additive in order to give the composition a lubricant's ability to suppress the vital activity of fungi a high stability of the emulsion was revealed during the testing in accordance with GOST 29188.3 by adding quaternary ammonium compounds and esters of p-hydroxybenzoic acid.

It is found that propyl p-hydroxybenzoate in a concentration of 0,2 % provides a high fungal resistance of 10 % to aqueous sizing solution IS-2 according to the results of testing by the method 4 of GOST 9.052.
