High-strength poly( l-lactide) fibres by a dry-spinning/hot-drawing process
High-strength poly( l-lactide) (PLLA) fibres (tenacity 2.1 GPa, Young's modulus 16 GPa) have been produced by dry spinning and subsequently hot drawing of PLLA ( M ̄ v = 9 × 10 5 ) from solutions in chloroform/toluene mixtures near the θ conditions where PLLA adopts an interrupted helical confo...

m, of the as-spun filaments, and was affected by the solvent composition, PLLA concentration in the spinning solution and preparation conditions. PLLA can exhibit an α-β crystal transition upon hot drawing. The theoretical strength of PLLA should amount to about 8 GPa as deduced from the diameter dependence of the tensile strength. |
