Implication

Randomized trial investigates mechanical performance and degradation of polyethylene/polylactic acid fibers, highlighting effective compositions.

Key Points

  • The study aims to understand the biodegradation mechanisms and mechanical properties of polyethylene/polylactic acid blend fibers.
  • Fabricated PE/PLA blend fibers (5–50 wt% PLA) via melt spinning.
  • Conducted soil burial degradation testing for 85 days according to ISO 17556:2019.
  • Performed mechanical characterization and degradation kinetics analysis.
  • The optimal 90/10 PE/PLA blend achieved a tensile strength of 64.88 ± 3.1 cN/Tex, higher than pure PE.
  • Fibers with 40 wt% PLA degrade approximately four times faster than pure PE, with weight losses of 12.3% versus 3.2%.
  • Higher PLA contents (≥20 wt%) led to significant phase separation and a reduction in elastic-modulus from 294.3 to 73.28 cN/Tex.
