This research investigates how woven textile form can emerge through the activation of intrinsic material behaviour, focusing on Swedish wool as an active and responsive bio-based material. While existing approaches to woven textile forms often rely on multilayer constructions, digital control, or synthetic responsive materials, this study proposes a material-driven alternative in which form arises through the interaction between fibre properties, yarn construction, and textile structure. Adopting a practice- based experimental methodology, the research examines how torsional energy introduced through high-twist yarns can be stored, regulated, and released within woven systems. Experiments are structured across three interconnected levels—material, yarn, and textile—combining parameter- driven testing with behaviour-driven observation. Results demonstrate that variations in twist level, ply structure, weave binding, and structural configuration influence the distribution and release of energy, producing self-forming behaviours such as crinkling, spiraling, pleating, and volumetric transformation. The findings reposition textile form as an emergent, material-driven process rather than a predetermined outcome. By demonstrating how natural fibres can act as active agents in form generation, the study contributes to design research through an integrated material–structure framework. It also highlights the potential of Swedish wool as a locally available yet underutilised resource, supporting more sustainable and materially engaged design practices.
