The agreement will see Selenis use its large-scale polymerisation and specialty polyester capabilities to support the broader commercialisation of this material.
Texnascis, the Selenis brand dedicated to sustainable and high-performance fibre development, will play a central role in the partnership.
The company launched Texnascis in September last year to advance recycling and circular practices within the textile industry.
Selenis strategy and integration director Eduardo Santos said: “At Selenis, we see strong potential in technologies that combine material innovation with commercial viability. Kintra has developed a differentiated fibre-grade PBS engineered for fibre production and premium textile performance. We are proud to bring this solution to scale through our manufacturing capabilities.”
The collaboration aims to supply the textile market with fibres that are both bio-based and biodegradable, addressing the need for alternatives to conventional petroleum-based synthetics.
According to industry data, more than 90 million metric tonnes of synthetic fibres derived from petroleum are produced each year, highlighting the scale of potential impact from scalable bio-based solutions.
Kintra Fibers has developed its proprietary PBS to be compatible with existing PET resin and fibre extrusion technologies, providing manufacturers a transition path to more sustainable options.
The technology is available in formats including FDY, ATY and DTY, supporting a range of knit and woven textile applications.
Kintra Fibers CEO and co-founder Billy McCall said: “Selecting the right industrial manufacturing partner to scale our technology was a top priority. Selenis brings the polymerization infrastructure, technical rigor and production control needed to manufacture our resin at the quality and volume the market demands. This partnership creates a clear path to market.”
Through this partnership, apparel brands and mills gain access to fibres that combine environmental attributes with compatibility for high-volume production.
Selenis and Kintra aim to facilitate wider adoption of sustainable materials across the global textile sector.
