Degradable Recycled Poly-poly Core Spun Thread
CICLO® Recycled Staple Spun Polyester Fiber & CICLO® Recycled Polyester Filament
This is a degradable recycled polyester core-spun sewing thread, made from degradable recycled staple spun polyester fiber and 100% degradable recycled polyester filament—both produced via mechanical way from PET plastic bottle flakes. It uses CICLO®-compliant additives, which create biodegradable "weak links in molecular chains" within the polymer matrix. This helps reduce the accumulation of synthetic fibers in landfills and oceans, as it can be decomposed by microorganisms under specific environments.
Performance Advantages
Utilizes patented technology to reduce landfilled plastic waste and marine plastic pollution, and is non-toxic to marine organisms.
Exhibits properties similar to natural fibers, maintaining fiber integrity with no loss in durability or performance, ensuring sewn products retain good appearance throughout their entire lifecycle.
The ultra-high strength from the recycled polyester filament core means that, compared to staple fiber threads, core-spun threads of the same thickness offer higher strength, making products more durable and better suited for high-speed sewing.
Biodegradation requires long-term exposure to moisture and environments with abundant microorganisms. It does not degrade during use and care, ensuring stability in application.
Its performance is comparable to virgin polyester threads, with lower production energy consumption,ensuring application effectiveness while better aligning with sustainability principles.
