摘要

Poly-(lactic acid) (PLA) is a biodegradable polymer from renewable resources produced as potential alternative to the synthetic polymers. One of the alternative applications is a preparation of PLA fibres. The PLA fibres prepared by classical spinning technology do not have good mechanical properties, especially elongation at the break. The prepared PLA fibres are very brittle with bad processability. The modification of the PLA fibres with plasticisers and additives/nanoadditives is one of the perspective ways for improvement of processability of the PLA fibres and increasing of multifunctional properties of these fibres. This work focuses on the preparation of fibres from various types of PLA modified with nucleating agent talc. The effect of content of various PLAs and additives on rheological properties of blends was evaluated. The thermal, mechanical and thermo-mechanical properties of prepared fibres from PLAs and modifiers were monitored.
