FIELD: polymer fibers.
SUBSTANCE: invention relates to fabrication of fibrous articles, in particular fibrous structures from polyesters. These structures are obtained from polyester fiber prepared in presence of catalyst, which comprises (A) mixture consisting of (i) component in the form of Ti compound formed from one or several compounds selected from titanium alkoxides described by presented below general formula (I) and products of reaction between those alkoxides and carboxylic acids described by general formula (II) or their anhydrides and (ii) component in the form of P compound consisting of compound having general formula (III) and/or (B) product obtained by reaction between component in the form of Ti compound formed from one or several compounds selected from titanium alkoxides described by general formula (IV) and product of reaction between those alkoxides and carboxylic acids described by general formula (II) or their anhydrides, and component in the form of P compound consisting of compound having general formula (V).
EFFECT: improved color tones and moldability.
