Global textile machinery and fiber producers are expanding multi-company collaborative networks to accelerate functional fabric innovation for high-growth athleticwear and lifestyle retail segments. At Performance Days Munich, Asahi Kasei’s premium stretch brand Roica united seven European textile mills - including Italian specialists Borgini Jersey, Reda, and Sitip—alongside Japanese knitting leaders Imai Kigyojo and Kawada Knitting. The joint initiative demonstrates advanced applications spanning 3D knits, seamless warp-knit constructions, and 17.5-micron Merino wool stretch blends. With the global activewear market projected to clear $434 billion, retail brands require versatile material architectures that balance stretch recovery, breathability, and structural durability across sportswear, innerwear, and tailored garments.

Functional sustainability meets supply chain demands

In response to tightening European eco-design regulations, the showcase emphasized functional fiber options such as Roica EF, manufactured from pre-consumer recycled waste, and partially degradable ROICA V550 polymers. These developments allow apparel brands to meet circular economy metrics without compromising technical performance.

Coordinating fiber innovation directly with elite European and Asian knitting specialists accelerates the commercialization of technical textiles, giving brand partners fully realized fabric solutions that streamline apparel development, stated a senior textile technology director.

While varying degradation conditions and higher raw material costs present adoption challenges, cross-border yarn alliances provide critical engineering scale for global fashion brands.

Introduced in 1971 by Japan’s Asahi Kasei Group, Roica manufactures premium stretch and elastane fibers for global activewear, intimate, and casual apparel markets. The brand expands market share through sustainable innovations like Roica EF and Roica V550, driving steady international revenue across European and Asian manufacturing hubs.
