摘要

In this paper, the effect of uniaxial deformation of PP/organoclay composite fibers in spinning and drawing on their supermolecular structure, thermal and mechanical properties is presented. The commercial organoclays Cloisite C15A and Cloisite C30B, both based on montmorillonite (MMT) were used in experimental work as inorganic fillers. The supermolecular structure of fibers was investigated by DSC analysis and X-ray diffraction (WAXS). The DSC measurements were carried out using conventional method (CM) and constant length method (CLM) in which the fibers with constant length during measurement were assured. The average orientation of fibers has been evaluated by the sonic velocity method. Intercalation of polypropylene in the interlayer galleries of organoclay was evaluated by SAXS method. Tenacity and Young's modulus of composite fibers were evaluated and discussed with regard to their thermal properties and supermolecular structure as well as intercalation and exfoliation of (nano)filler in polymer matrix.%V tomto príspevku je prezentovaný vplyv jednosmernej deformácie PP/organoílových kompozitných vlákien pri zvlákňovaní a dlžení na ich nadmolekulovú štruktúru ako aj termické a mechanické vlastnosti. Ako anorganické plnivá boli v práci použité komerčné typy organoílov Cloisit C15A a Cloisit C30B, obidva na báze montmorilonitu. Nadmolekulová štruktúra bola hodnotená pomocou DCS analýzy a metódy difrakcie X-lúčov. DCS merania boli stanovené konvenčnou metódou (CM) a metódou konštantnej dlžky (CLM), pri ktorej je počas celého merania zaistená konštantná dlžka vzorky vlákna. Priemerná orientácia vlákien bola stanovené metódou rỳchlosti zvuku. Na stanovenie interkalácie polypropylenu v medzivrstvových galériách organoílov bola použitá metóda SAXS. Pevnost' a Youngov modul kompozitných vlákien boli hodnotené v závislosti na termických vlastnostiach a nadmolekulovej štruktúre, ako aj v závislosti na interkalácii a exfoliácii (nano)plnív v polymérnej matrici.
