Roica debuts at Functional Fabric Fair Portland with 14 partner mills

Asahi Kasei's premium stretch fibre brand Roica will make its debut at Functional Fabric Fair Portland on 27-28 October 2026, presenting fabric developments from six European and eight Asian textile partners at stand 256 in the Oregon Convention Center. The showcase anchors the Japanese multinational's fibre portfolio to a partner network spanning Italy, Hong Kong and Taiwan, and signals where stretch fabric development capacity is concentrated for performance and athleisure programmes.

The European contingent comprises Borgini Jersey, Brugnoli, Cifra, Penn Solutions, Sitip and Tiba Tricot. Their developments target premium athleisure fabrics combining refined aesthetics with a luxurious handle, engineered knitted constructions designed to improve ergonomic comfort, seamless garment technologies, and technical fabrics for cycling and other performance applications. The collection also includes three-dimensional mesh structures suitable for apparel, accessories and bags, extending engineered stretch fabrics beyond conventional clothing applications.

The Asian group brings eight manufacturers to the stand: Derun Industrial and Sun Hing Textiles from Hong Kong, plus Wing Yue Textile and Taiwan-based Everest Textile, Minlan, Ray Fabrics, Tex Tile and Wu Luen. Their developments address the convergence of outdoor performance, urban mobility and everyday comfort.

Applications include:

• Lightweight knitted and woven fabrics
• Recycled material solutions
• Advanced four-way stretch constructions
• Engineered textiles for durability, flexibility and freedom of movement
• Soft circular knitted fabrics, stretch mesh and lace constructions
• Lightweight materials for innerwear and next-to-skin use

The partners' target segments span outdoor clothing, cycling apparel, commuting garments, urban sportswear and modern athleisure. Buyers can also visit individual partner stands: Brugnoli at 773A, Everest Textile at 328, Minlan at 1041, Ray Fabrics at 128, Tex Tile at 777 and Wu Luen at 783.

Which certified fibres are on show?

Two Roica fibres carry third-party credentials that sourcing teams can trace. Roica EF uses pre-consumer recycled yarn waste as part of its raw material input and holds Oeko-Tex Standard 100, Class I certification — the strictest product class, applicable to articles for babies and toddlers. The fibre is designed to deliver consistent stretch performance while supporting more resource-efficient material production.

Roica V550 takes a different compliance angle: the stretch fibre is developed with degradable characteristics. Unlike conventional elastane, which generally resists degradation, V550 is designed to break down gradually under appropriate conditions, although the company states complete degradation has not been verified. The fibre has achieved Cradle to Cradle Certified Material Health Gold Level. Sourcing teams should treat the degradability claim as design intent, not a verified end-of-life outcome.

Two functional fibres round out the display. Roica CF incorporates odour-neutralising functionality directly into the yarn, targeting compounds associated with perspiration and foot odour including ammonia, acetic acid and isovaleric acid. The technology aims to retain effectiveness through repeated laundering without relying on conventional textile finishing treatments — a distinction that affects wet-processing steps in the supply chain. Roica SF, a heat-activated fibre, targets dimensional stability and clean-cut edges: it helps suppress laddering and curling in knitted fabrics, reduces yarn slippage in lightweight wovens, and improves recovery so garments hold their shape in use.

What does the showcase signal for sourcing?

Asahi Kasei developed Roica and introduced it in 1971; the brand now serves apparel manufacturers worldwide across stretch recovery, garment stability, odour management and alternative material inputs. The company positions the Portland debut under the brand message 'Stretch Your Future', framing cross-supply-chain collaboration as the driver of new developments in comfort, fit, functionality and material innovation.

Functional Fabric Fair Portland gathers technical textile manufacturers, fibre producers and apparel brands around emerging materials for the performance and outdoor sectors. For Roica, the event demonstrates the breadth of its international partnerships and the role of specialised stretch fibres in increasingly sophisticated fabric constructions.

The underlying demand signal is category blurring: distinctions between activewear, outdoor clothing and everyday apparel continue to narrow, and fabric developers are engineering single constructions to serve multiple end uses. Asahi Kasei says continued collaboration with European and Asian manufacturers will expand application of its stretch technologies while supporting product development aligned with changing consumer expectations and industry requirements.

For sourcing and product teams attending Portland, the practical decision is whether to qualify Roica-based developments from this partner network now — with the Oeko-Tex and Cradle to Cradle credentials already documented — or wait for verified degradation data on V550 before committing to end-of-life claims in product marketing.
