Invista has developed a new Lycra fibre produced with a renewable bio-based raw material derived from corn.

The fibre will be available globally and for use in a wide variety of apparel fabrics and garments, and offers retailers and manufacturers of stretch fabrics a spandex fibre option that can impact the overall lifecycle analysis of the fabric and garment.

Invista also says it does not anticipate a need to re-engineer fabrics and finishing processes, or garment patterns.

Around 70% by weight of the new Lycra bio-derived spandex fibre comes from a renewable source made from dextrose derived from corn.

The use of a renewable feedstock results in a lower CO2 emissions footprint than spandex produced using traditional raw materials, the company says.

"We are very aware that sustainability topics are becoming increasingly important in the textile and apparel value chain, with growing awareness and building education on the subject at the consumer, brand/retail and mill level," said Invista's apparel global sustainability director, Arnaud Tandonnet.

The production of commercial quantities is planned for the autumn/winter 2015 and spring/summer 2016 collections.
