Abstract
This work is focused on characterization of spinning process of PLA fibres. PLA polymer with high melting point was modified by two hydrolytic additives in amounts (0 and 1 wt. %). Fully drawn (FDY) PLA fibres were prepared by melt spinning technique in the company Chemosvit Fibrochem a. s. (Svit, Slovakia). Preparation of PLA fibres was done by two different processes of continuous and discontinuous type. Different drawing ratios, take-up speeds and spin finishes for optimal fibre properties were used. Physical and mechanical properties of prepared FDY fibres, such as elongation and tenacity were measured. Prepared PLA fibres with different hydrolytic additives were process able in manufacturing process and this material could be used for various textile and composite applications.
