Structure Development and Mechanical Properties of Biodegradable PBST High-Speed Melt Spun Fibres

摘要：

Biodegradable random copolymer poly(butylene succinate-co-terephthalate) (PBST), with 70 mol％ butylene terephthalate (BT), was melt-spun into fibers with take-up velocity up to 4000 m/min. The structure development and mechanical properties of the as-spun fibers were investigated through WAXD, tensile test and cyclic deformation test. With increasing take-up speed, a steady improvement in tensile strength, elongation at break and elastic property was found. The fibers prepared over the entire takeup speed possessed high crystallinity.
