CELYS™ is a brand-new polyester of designed chemical construction through a proprietary polymerisation process.

PET is widely used as fibres in the textile industry because of its excellent physical and chemical characteristics. However, it is well known as a non-biodegradable material.

In our effort for developing CELYS™ fibres, we set “biodegradable” as one of our must-be targets. Our idea was simple and straightforward, that was, easy-breaking ester linkage would result in fast degradation.

After many trials and errors, we successfully introduced easy-breaking ester linkages into the polyester backbones during the polymerisation, which greatly facilitated the cleavage of the ester linkages when exposed to the right environment.

As a result, our CELYS™ fibres fully biodegraded within 180 days in an industrial compost.
