HKRITA and Epson develop silk-like regenerated fiber from cotton

The Hong Kong Research Institute of Textiles and Apparel ("HKRITA") and Seiko Epson Corporation ("Epson"; TSE: 6724) have succeeded in developing new regenerated cellulose fiber with a silk-like sheen from waste cotton fabric through a new production process.

A movement toward using fibers recycled from discarded clothing has been gaining momentum, driven by a growing recognition of waste clothing as a global environmental issue. In Europe in particular, a move is under way to use more regenerated fiber and reduce textile waste.

To address societal issues surrounding textile waste, HKRITA and Epson have been conducting research and development on regenerated fibers since signing a joint development agreement in January 2024. As a result of this collaboration, the partners have successfully developed regenerated cellulose fiber using a new production process that transforms discarded cotton fabric into regenerated fiber.

This new process was made possible by integrating Epson's proprietary Dry Fiber Technology for defibrating textiles with HKRITA's fiber-dissolving technology. The process involves (1) defibrating discarded cotton fabric into a powder-like state, (2) dissolving the cotton in a solvent, and (3) extruding it through a nozzle into a coagulation bath, where it solidifies and is spun into fiber.

The regenerated cellulose fiber produced through this process is expected to have both a smooth, silky sheen and the strength of cotton. This fiber is expected to be used in high-end materials such as scarves, neckties, and suit linings. Moreover, since the short fibers that occur during the regenerated fiber production process can also be used rather than discarded, as was usually the case, this regeneration process can help to increase the total clothing recycling rate.

"As an applied research center, HKRITA is dedicated to solving real-world problems and enhancing current practices and products," said HKRITA CEO Jake Koh. "We are thrilled to collaborate with Epson to recycle fibers and repurpose them into high-quality yarns. This cross-industrial collaboration is not only reimagining materials but also redefining the future of sustainable production."

Epson Executive Officer Satoshi Hosono, who serves as the deputy general administrative manager of the Global Environmental Strategy Promotion Office and as the deputy general administrative manager of the Technology Development Division, said, "We are extremely pleased with the results that this joint development project has yielded. The selective application of this new wet process and our previously developed dry process should enable fiber to be regenerated from all waste cotton fabrics while reducing environmental impact."

Information about the work under this joint development project was exhibited at HKRITA's Booth 2415 at Textiles Recycling Expo 2025, held in Brussels, Belgium, from June 4, 2025.

Looking ahead, HKRITA and Epson will continue to combine their advanced technologies to accelerate the adoption of regenerated fibers, contributing to global efforts to solve the challenge of clothing recycling.

Sustainable, lightweight, and sound absorbing: Polyester-based front trunk solution for BEVs

As car manufacturers look to further reduce their carbon footprint, Autoneum has developed an innovative front trunk solution for battery electric vehicles (BEVs), made entirely from polyester-based textile. The Ultra-Silent Frunk offers significant weight reduction, improved acoustic and thermal insulation, and uses up to 70 percent recycled material, supporting sustainable and efficient vehicle design. Autoneum, global technology leader in acoustic and thermal management for vehicles, has already received orders for the new frunk from three major OEMs in Asia and Europe to be built in three BEV models. Series production for two BEVs has been underway in China and Germany since last year.

Modern testing methods for raw cotton

The 38th International Cotton Conference Bremen will take place from 25 to 27 March 2026 at the Bremen Parliament. This conference has traditionally stood for in-depth expertise and international exchange. The program will focus on technical innovations, market trends, and regulatory frameworks across the entire value chain – from agriculture to the circular economy. With high-profile speakers, the conference is regarded as the key meeting point for the global cotton industry. Today’s focus: Cotton quality and testing methods.

Rieter responds to higher raw material prices

Global political and economic developments have been leading to rising raw material and energy costs for some time. The textile machinery industry is also affected by this trend. Rieter machines and components consist to a large extent of steel, copper, aluminum and electronics. These materials in particular have seen higher demand and higher prices in recent months.
