Sažetak

The treatment causes only minor decrease in fibre, i.e. yarn strength, while breaking elongation increases significantly, almost up to 150 % in comparison to the untreated sample. Organic solvents, i.e. plasticizer solutions in the organic solvents mixture influence fibre properties in a very favorable way, i.e. they can enable better dyeing, better moisture absorption, easier treatment in further phases of textile products manufacture and generally better usability. X-ray structural analysis was used to examine the influence of the treatment of polyester fibres in the form of filament yarn, fineness 75/26 dtex, with solutions 0.3, 0.6 and 0.9 % hydroquinone and -naphtole in the solvent mixture which contained chlorophorm and methanol (solubility parameter 11.7) on changing of crystalline degree and crystallite size. It was found that treated fibres showed sharper reflexion on diffractograms than untreated ones, i.e. they showed higher crystalline degree but smaller crystallite size.
