First in the world! Scale Production of Spandex with Bio based BDO

  • 2022-10-05

The forum will discuss the cutting-edge technologies and product applications of bio based materials, such as PLA, FDCA, PHA, bio PBS and other bio based plastics and bio based fibers, focusing on the modification, processing and downstream applications of polylactic acid (fibers, film bags, catering utensils, packaging materials, etc.). Welcome to scan the code and register for the exhibition.

On September 28, Leica, a global leader in the development of innovative fiber and technology solutions for the textile and clothing industry, announced that it had cooperated with Qore ® Sign an agreement to become the world's first large-scale use of a new generation of 1,4-butanediol (BDO) QIRA ® As the main raw material for the commercial production of bio based polyurethane fiber. Through this cooperation, LYCRA ® (Leica ®) 70% of the fiber will come from renewable raw materials every year. Compared with the equivalent products made from fossil fuel raw materials, this change is expected to transform LYCRA ® (Leica ®) The carbon footprint of fiber can be reduced by up to 44%, while maintaining the same level as that of traditional LYCRA ® (Leica ®) High quality performance parameters of the same fiber.



QIRA ® It will be produced in Cargill Biotechnology Park and the corn refinery in Eddiver, Iowa. The plant is currently under construction and will be put into operation in 2024. First use of QIRA ® Made of renewable LYCRA ® (Leica ®) The fiber will be produced in Leica's Tuas factory in Singapore in 2024. Leica is currently engaged with brands and retail customers who expect to use bio based apparel solutions.

"As part of our sustainable development goals, we are committed to providing products that support the circular economy, while helping our clothing and personal care customers reduce their carbon footprint," said Julien Born, CEO of Leica ® Cooperation, we have resonance in the vision of innovative and sustainable solutions. Their expertise in fermentation process technology and understanding of chemical value chain make them a bio based LYCRA to help develop commercial scale ® (Leica ®) The ideal partner for fiber. "

"We are proud to work with Leica to bring this sustainable material solution to the market. This cooperation shows that QIRA ® It directly replaces the traditional BDO, thus significantly improving the sustainable image of fiber, "Qore ® Jon Veldhouse, CEO, said, "QIRA ® It is an innovative platform for chemicals that can be used in a variety of cross industry applications. "

By QIRA ® Made of the first generation renewable LYCRA ® (Leica ®) The fiber will use corn grown by Iowa farmers as raw material, which will significantly reduce carbon dioxide emissions. In addition to replacing the limited resources with renewable resources every year, another advantage for factories, brands and retailers is that there is no change in fiber performance, and there is no need to redesign fabrics, clothing patterns or processes. In 2014, LYCRA ® (Leica ®) The brand launched the world's first bio based spandex, demonstrating the same performance. Leica's technology of manufacturing renewable elastic fibers from bio based BDO has been patented.

About Qore ® LLC

Qore ® Jointly established by Cargill and HELM, it will help leading brands replace fossil based chemicals with bio based intermediates. The core of the joint venture is to produce the next generation of bio based 1,4-butanediol (BDO) QIRA ®。 QIRA ® It is made biologically through the fermentation of plant sugar, which can reduce greenhouse gas emissions by up to 93% when replacing the chemical intermediates made from traditional fossil sources that are widely used today. Biobased QIRA ® It is used in the same way as its chemical counterpart, but has significantly better environmental performance. (Source: Jururu Information)

From October 20 to 21, 2022, the Forum on the Technology and Application of Biobased Materials jointly sponsored by the Biodegradable Materials Research Institute and TK Biobased Materials will be held in Suzhou. The Forum will lay out the whole industrial chain of bio based materials, invite experts from authoritative institutions and leading enterprises in the industry, share and learn together, and promote the healthy and rapid development of China's bio based industry.
