Maire has announced its expansion into the sustainable textile sector through its subsidiary Nextchem. The company introduced NX Conser PolyFlex technology, designed to produce polytetramethylene ether glycol (PTMEG), an important material used in making spandex fibers.

The technology was developed by CONSER, a licensing partner of Nextchem. PTMEG is a key raw material used in elastic fibres, which are widely applied in sportswear and technical textiles. Demand for such materials has been rising due to the growth of performance clothing and the increasing use of flexible fibres in protective and industrial applications.

NX Conser PolyFlex allows PTMEG to be produced from both traditional petrochemical sources and bio-based tetrahydrofuran (THF). This gives manufacturers the option to include renewable raw materials in their production processes. As a result, it supports efforts to reduce carbon emissions in the textile industry, which contributes a significant share to global greenhouse gas emissions.

This technology is part of the newly launched NXPand platform, through which Nextchem plans to enter the sustainable textile innovation space. The move reflects the growing demand for low-carbon materials in fibre production, especially as brands focus more on climate goals and circular economy practices
