FIELD: artificial fibers.
SUBSTANCE: process comprises treating fibers at least partially cleaned with the aid of biocyde-effective amount of biocyde composition selected from group consisting of didecyldimethylammonium chloride, didecyldimethylammonium bromide, water-soluble copper salts, and mixtures thereof. When dried, fiber exhibits improved biostability and can be improved (refined) without considerable consumption of power and without considerable loss in fiber length and formation of small pieces. Fiber can be employed in manufacture of fibrolite slabs, panels, and the like.
EFFECT: increased biological stability.
