  • Biodegradable: 100% compostable.
  • Lightweight: Specific weight less than for natural fibres.
  • Tenacity: Comparable to synthetic yarns.
  • Comfort: More hygroscopic than synthetic fibres and faster drying than natural fibres.
  • Wearability: Elastic recovery greater than 90% after 5% extension.
  • UV Resistance: Excellent; UV radiation is dissipated.
  • Safety: Low flammability (LOI > 26%); does not emit toxic fumes.
  • Bacteriostatic effect: released silver ions exert their antimicrobial action.
