From the Sector

Celanese Corporation, a specialty materials and chemical company, and Under Armour, Inc., a company in athletic apparel and footwear, have collaborated to develop a new fiber for performance stretch fabrics called NEOLAST™. The innovative material will offer the apparel industry a high-performing alternative to elastane – an elastic fiber that gives apparel stretch, commonly called spandex. This new alternative could unlock the potential for end users to recycle performance stretch fabrics, a legacy aspect that has yet to be solved in the pursuit of circular manufacturing with respect to stretch fabrics.

NEOLAST™ fibers feature the powerful stretch, durability, comfort, and improved wicking expected from elite performance fabrics yet are also designed to begin addressing sustainability challenges associated with elastane, including recyclability. The fibers are produced using a proprietary solvent-free melt-extrusion process, eliminating potentially hazardous chemicals typically used to create stretch fabrics made with elastane.

NEOLAST™ fibers will be produced using recyclable elastoester polymers. As end users transition to a more circular economy, Celanese and Under Armour are exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure.

In addition to the sustainability benefits, the new NEOLAST™ fibers deliver increased production precision, allowing spinners to dial power-stretch levels up or down and engineer fibers to meet a broader array of fabric specifications.

Eurotay showcased at Denim Première Visionits vision and products through the AW 23/24 collection inspired by two themes: Nostalgia and #Still Possible.

Nostalgia stands for heritage and advancement, taking inspiration from classic favorites while enhancing new and existing styles. Setting the tone of the line are vintage-looking washes, echoing the 80s and 90s light acid washes as well as used look with bumped edges or fringed hems. Stretch, comfort stretch with very little elastane and even rigid denim feature in this collection providing catering to any need or preference.

The #Still Possible collection is based on the premise that the textile industry is one of the most polluting ones on the planet, thus it aims to shine a light on how a denim garment can still be made whilst reducing the number of resources employed and by being more conscious about the materials chosen. By using EIM and LCA, garment durability, traceability, recyclability as well as material health are guaranteed, for a collection that looks to a brighter and greener future.

Eurotay has been committed from day one to using less water, less energy, less chemicals to reduce its environmental footprint and its carbon emission and meet the goals of EU Green Deal targets. The company is geared towards building a more and more responsible industry by working hard to reach a set of sustainable goals by 2025. Additionally, the company is working on developing Life Cycle Assessment (LCA) and EPD (Environmental Product Declaration) measuring the global warming, water consumption, land occupation, eutrophication and abiotic depletion performances.

• Monforts customer Kipaş has been selected as the sole denim manufacturing partner in the €6.7 million European Union-funded New Cotton Project, involving the brands adidas and H&M, working in a consortium with suppliers, innovators and research institutes.

Kipaş, based in Kahramanmaraş, Turkey, is currently installing its third Monforts Montex stenter along with a third Monfortex compressive shrinkage system in a combined configuration dedicated to denim production.

This follows the successful installation and commissioning of the second Montex and Monfortex lines at the Kahramanmaraş plant in 2018, which Kipaş Vice Chairman of the Board Ahmet Öksüz said had immediately exceeded expectations.

“We performed a very thorough technical investigation based on the latest Industry 4.0 analysis before the purchase, to determine what we needed, and the Monforts technology met all our requirements,” he said, in an interview with Textilegence magazine. “The Monfortex is equipped with a variety of features not found on classical shrinkage machines and the production can be monitored from beginning to end. It also exceeded our expectations in energy cost savings.”

Kipaş subsequently received a special certificate from Monforts in recognition of its exceptional utilisation of the technology to its full potential.

The latest Montex stenter now being installed at Kipaş is a 12-chamber unit with a working width of 2 metres featuring all of the latest automation features. The Monfortex unit, also with a working width of 2 metres, is in a ‘double rubber’ configuration, comprising two compressive shrinkage units and two felt calenders in line. This allows the heat setting of elastane fibres and the residual shrinkage of the denim to be carried out simultaneously, for a significant increase in production speeds.

“Around 90-95% of denim fabric production now contains elastane fibres and the Monforts system has allowed us to simultaneously increase our production and quality in this respect,” Mr Öksüz said.

Regenerated cotton
For the next three years within the New Cotton Project, Kipaş will manufacture denim fabrics based on the cellulose-based fibres of Infinited Fiber Company of Finland, made from post-consumer textile waste that has been collected, sorted and regenerated.

The patented technology of Infinited, which is leading the consortium of 12 companies, turns cellulose-rich textile waste into fibres that look and feel like cotton.

“We are very excited and proud to lead this project which is breaking new ground when it comes to making circularity in the textile industry a reality,” said Infinited co-founder and CEO Petri Alava. “The enthusiasm and commitment with which the entire consortium has come together to work towards a cleaner, more sustainable future for fashion is truly inspiring.”

Take-back programmes
Adidas and H&M will establish take-back programmes to collect the clothing that is produced, to determine the next phase in their lifecycle. Clothing that can no longer be worn will be returned to Infinited, for regeneration into new fibres, further contributing to a circular economy in which textiles never go to waste, but instead are reused, recycled or turned into new garments.

The aim is to prove that circular, sustainable fashion can be achieved today, and to act as an inspiration and stepping stone to further, even bigger circular initiatives by the industry going forward.

The EU has identified the high potential for circularity within the textile industry, while simultaneously highlighting the urgent need for the development of technologies to produce and design sustainable and circular bio-based materials. Making sustainable products commonplace, reducing waste and leading global efforts on circularity are outlined in the European Commission’s Circular Economy Action Plan.

Fashion brands produce nearly twice as many clothes today as they did 20 years ago and demand is expected to continue growing. At the same time, the equivalent of one garbage truck of textiles is landfilled or burned every second. Most of the textile industry’s environmental problems relate to the raw materials used by the industry – cotton, fossil-based fibres such as polyester, and viscose as the most common man-made cellulosic fibre, are all associated with serious environmental concerns.
