Solvay launches first partially bio-based textile yarn

International chemical and fibres group Solvay is globally launching Bio Amni, the first partially bio-based polyamide textile yarn developed by the company.

The yarn is a polyamide 5.6, which is produced entirely at the company’s textile industrial unit in Brazil.

The development of Bio Amni follows the growing global trend in demand for more sustainable textile products, especially bio-based materials, the firm says.

Solvay’s research and innovation teams worked on the creation of the product for two years.

“Sustainability is one of the main drivers of the global textile market,” says Antônio Leite, global vice president of polyamides and fibres at Solvay. “Solutions and products must add value to the entire consumer chain – from its base to end consumers of textiles – and have less of an impact on the environment. Solvay’s Bio Amni is part of a portfolio evolution to offer customers the most innovative products on the market.”

Solvay says the textile sector currently faces three main challenges in relation to the environment and sustainability: resources, the production process, and disposal. The firm already has developed sustainable alternatives in the production process, using cleaner energy sources, closed water circuits, and zero effluent emissions at its industrial unit in Brazil, as well as more biodegradable products to support more sustainable disposal.

With the launch of Bio Amni, sustainable textiles will now account for 30% of Solvay’s global polyamide portfolio, a figure which the group expects to reach 50% in the next three years.

The launch follows that of Amni Virus-Bac Off, a functional polyamide that inhibits contamination between textiles and users, preventing the fabric transmitting viruses, including coronaviruses, and bacteria; and Amni Soul Eco, said to be the world’s first biodegradable polyamide textile yarn, which facilitates the decomposition of textile articles in about three years after disposal in controlled landfills.
