As the fashion industry accelerates towards a more sustainable future, Celys is helping it break new ground. In a world where carbon emissions, waste, and plastic pollution define the environmental cost of fashion, Celys™ stands apart, designed to deliver high-performance functionality with no compromise on end-of-life impact.
A Game-Changer in Responsible Fibre Innovation
Celys™ is an engineered, certified compostable polyester fibre. It combines the technical performance apparel brands rely on—durability, moisture management, and versatility— with true circular design. Unlike traditional synthetics, Celys™ returns to the earth at the end of its life, without leaving persistent microplastics or contributing to landfill overflow. It is a new generation of material: compostable, responsible, and uncompromising.
Engineered for Performance, Designed for the Planet
Celys™ is built for brands that would not sacrifice performance for sustainability—or vice versa. Key benefits include:
Unique Performances of Celys™ Fibres
- Cotton Touch: The unique molecular structure of Celys polyester creates a cotton-like texture and is softer than standard PET.
- Low Pilling: The special chemical structure of Celys polyester offers a natural solution to the anti-pilling concerns associated with regular PET fibres.
- Low-Temp Dye: Unlike regular PET fibre, Celys fibre can be dyed at 100°C, either with cationic dyes or medium and low-energy dispersed dyes.
- Natural Wicking & Breathability: The hydrophilic groups in the Celys fibre structure absorb water instantly. The moisture regain is about four times that of regular PET fibre.
- Quick Dry: Celys exhibits good quick-dry performance, enhanced by its many natural channels that facilitate faster vaporisation.
Whether worn next to the skin or layered in technical garments, Celys™ delivers a premium experience with a radically lower environmental impact.
