Product & Application
Due to its unique chemical structure, CELYS™ polyester has a great combination of attributes that outperform normal PET fibres, and is versatile for all textile applications.

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.
The unique molecular structure of CELYS™ polyester creates a cottony touch, and is softer than normal PET.
The special chemical structure of CELYS™ polyester leads to a lower tensile strength than normal PET fibre. This creates a natural solution to the anti-pilling concerns for normal PET fibre.
Unlike normal PET fibre, CELYS™ fibre can be dyed at 100°C, either through cationic dyes, or medium and low energy disperse dyes.
As a polyester fibre, CELYS™ maintains good quick-dry performance, and it is even enhanced by the many natural channels with faster vaporisation.
The hydrophilic groups in the CELYS™ fibre structure make it absorb water instantly. The moisture regain is about 4 times that of normal PET fibre.
There are many naturally formed channels inside CELYS™ polyester fibre, which can quickly carry away moisture from your skin for great breathability.
