Fashion's Interest In Alternative Fabrics Keeps Growing

Eco-friendly materials straddle the cutting edge of style and science.

Over the next 12 months, brands are expected to announce partnerships with businesses that have figured out ways to make leather without cows, silk without worms, fur without animals and fabrics from recycled waste.

Already this year, Salvatore Ferragamo has been selling scarves made of orange fibres while Stella McCartney produced two outfits made with the spider-inspired silk.

"They have not completely perfected it but it is a silk; it is literally a silk but it is a slightly different texture than the silk we normally use," said Claire Bergkamp, head of sustainability and ethical trade at the Stella McCartney brand.

As with any new technology at an early stage of development, initial production of such fabrics continues to be limited and the finished products costly. Bolt, for example, introduced a lottery in March to sell its first spider-inspired silk neckties, at $314 (U.S.) each.

After studying spiders' DNA and their webs, Bolt Threads' engineers developed similar proteins that are injected into yeast and sugar and then subjected to a proprietary fermentation process. The Japanese company Spiber has an agreement with the North Face, the American activewear company (in 2016, they developed a Moon Parka prototype) and AMSilk, a German company, has partnered with Adidas on products that they will not identify, but say are expected to go on sale next year.

Adidas is producing sneakers made with plastics recovered from beaches and oceanfront communities, part of a product line developed through its partnership with the activist anti-plastic group Parley for the Oceans. (McCartney, an Adidas collaborator, provided some of the designs.)

Recycled fruit waste is another promising substance for the creation of alternative fabrics. The Italian company Orange Fiber provided the material for Ferragamo's capsule scarf collection. Ananas Anam, based at the Royal College of Art in London, uses pineapple leaf fibres to create a nonwoven leatherlike material called Piñatex and brands such as Edun, the sustainable fashion label owned by LVMH Moët Hennessy Louis Vuitton, are creating items from it.

Mycelium, the rootlike fibre of mushrooms, is being processed as a leather substitute by MycoWorks, a San Francisco startup. But some specialists say the material, which looks like suede, needs to be tested for durability.

In addition to bio-fabricated materials, the Stella McCartney brand and its founding partner, the luxury group Kering, are investing in ways to recycle fashion items and use fewer resources, such as water. McCartney's Falabella Go bags are made of recycled polyester and Econyl, a nylon produced from recycled fishing nets, carpets and other such waste, manufactured by the Italian company Aquafil.

In recent years, several venture capital firms have supported the development of alternative fabrics, especially when biofuels, including corn and algae, failed to live up to their initial promise. One of the latest and most high-profile investors is the Russian entrepreneur Miroslava Duma, founder of the fashion and lifestyle website Buro 24/7.

In May, Duma introduced Fashion Tech Lab, a venture that funds and develops new technologies in sustainable fashion. It has US$ 50 million in funding and the advisory services of Carmen Busquets, the e-commerce investor, and Diane von Furstenberg. Orange Fiber and Vitro Labs, a company that is developing lab-grown variations of fur and leather from stem cells, were among the organisation's initial beneficiaries.

Suzanne Lee, who has almost 20 years of experience in fashion technology, said, "It feels like there has not been as much innovation in terms of new materials as in the past five years, with sustainability being the main driver." She is now chief creative officer at Modern Meadow, a New Jersey-based company that specialises in laboratory-grown bio-fabricated leather materials.

Lee said that, just as shortages after the Second World War drove the development of fossil fuel-based materials such as Lycra and polyester, the prospect of limits on natural fibres and leather are pushing the fashion industry to find alternatives.

Modern Meadow has developed a yeast that, when mixed with sugar, produces a collagen that then is purified, processed and tanned to create material with a look and feel similar to that of leather.

The company said that it was planning to unveil its first commercial product next year and that it had partnered with one major luxury player, which it declined to reveal now.

However, reflecting its luxury ambitions, the company has retained the advisory services of three fashion veterans: Mimma Viglezio, formerly the executive vice president of global communications at Gucci Group; François Kress, who left the chief executive position at Carolina Herrera in January; and Anna Bakst, formerly group president of shoes and accessories at Michael Kors.

Similarly, some of fashion's historic houses are pioneering in the field. Chanel, known for putting a healthy dose of pressure on suppliers to create new yarns and fabrics every season, has been working with paper yarns and is researching the use of 3D printing for ready-to-wear clothing. The house, in what it said was a first, presented suits at its fall 2015 couture show that were made of material produced by a 3D printer from sintered, or compressed, powder & then embellished with embroidery and braid by Lesage, one of Chanel's métiers d'art houses.

"Karl Lagerfeld says we should do things that are unimaginable," said Hubert Barrère, the creative director at Lesage. "Creativity is about being in tune with your time."
