When wool meets polylactic acid (PLA), traditional worsted fabrics are undergoing a material revolution. At the 2026 China International Textile Fabrics & Accessories (Autumn/Winter) Expo, Jiangsu Sunshine Group, together with Anhui Fengyuan Bio-tech, Huamao Textile, and Wuxi Aike Plush Technology, launched a PLA industry chain collaborative development center, marking the shift of wool-bio-based fiber blending from laboratory to mass production. This technology, appraised as internationally advanced, is reshaping the supply logic of premium fabrics.
Event Background
The expo, held from August 25 to 27 at the National Exhibition and Convention Center (Shanghai), featured Sunshine Group's four themed series: Form, Frontier, Fidelity, and Flourish, covering urban commute, light outdoor, sustainability, and health care. The Fidelity series focuses on blends of wool with bio-based and biodegradable fibers, while the Flourish series highlights bio-based antibacterial fabrics. Notably, the full range of PLA/wool blended fabrics has achieved mass production, indicating that bio-based fabrics are no longer niche concept products but mature categories with stable supply capabilities.
Sunshine Group's collaboration with Fengyuan Bio-tech, Huamao Textile, and Aike Plush covers the entire chain from fiber raw materials, spinning, weaving, to finishing. Fengyuan is a major supplier of PLA raw materials, Huamao has large-scale spinning capabilities, and Aike specializes in plush fabric processing. This cross-sector collaboration solved technical challenges in fiber blending ratios, dyeing, and finishing, allowing fabrics to maintain wool's natural texture while gaining soft hand-feel and natural antibacterial properties.
Industry Impact
The scale-up of PLA/wool blended fabrics has practical implications for both buyers and mills. For brand sourcing teams, the biodegradable nature helps meet environmental regulations in markets like the EU, while natural antibacterial and anti-mite properties can replace some chemical finishes, reducing environmental pressure. For mills, PLA fibers require lower dyeing temperatures, saving energy when blended with wool, but attention must be paid to PLA's lower heat resistance, requiring adjustments in ironing and setting processes. Mills that master these techniques will gain an edge in green orders.
On the first day of the expo, Sunshine Group's booth attracted numerous domestic and international brand sourcing managers and designers. Clients focused on shrinkage control, color difference standards, and care performance—challenging aspects of blended fabrics compared to pure wool. Senior officials from the China National Textile and Apparel Council, including President Sun Ruizhe, visited the booth, affirming Sunshine's dual-drive strategy of technology and green development. This high-level attention reflects the rising strategic position of bio-based materials in textiles.
From a technical maturity perspective, the compatibility of PLA and wool has been resolved, but cost remains a key barrier to widespread adoption. Currently, PLA raw material prices are higher than conventional polyester, making blended fabrics premium-priced. However, as Fengyuan and other producers expand capacity, PLA costs are expected to decline, enhancing price competitiveness. For buyers, this is a window to build differentiated bio-based product lines.
