Eastman launches “the next generation” of polyester fibres
05/08/2016
Avra Performance Fibers is a family of performance fibres enabled by a proprietary spinning technology. The first product is a ribbon-shaped synthetic fibre with “a combination of shape and size never before seen”. Eastman also said the project is backed by a company with “a 96-year history of manufacturing excellence”.
Eastman vice-president Tim Dell said at the time of the launch: “The apparel industry has known for decades that finer fibres create fabrics with softer hand and enhanced performance. There is a limit, however, to how fine you can go and still knit or weave on conventional equipment.”
He explained that Avra’s ultra-thin polyester fibres are extruded and held together by a proprietary removable polymer, enabling knitting or weaving. Once the fabric is made, the removable polymer washes away in hot water, resulting in ribbon-like fibres that are smaller than standard polyester fibres. “The result is a distinctly silky fabric that keeps wearers drier and more comfortable than ever before,” Mr Dell said.
Performance benefits include high levels of moisture management and a chemical-free ‘cool to the touch’ sensation. Fabrics made with Avra dry up to 50% faster than conventional polyester fabrics and offer good drape and softness.
Avra fibers are made in the US in collaboration with Unifi. This joint effort has enabled a physical plant expansion at Unifi and provided additional jobs to the region. “Innovation in the Americas is more important today than ever before,” said Mark McNeill, vice-president of technology and business development at Unifi. “Combining the technology and quality-driven expertise of Eastman and Unifi will help provide the industry with the next level of performance-enhancing fibres.”
