The TYPE-O CAP Transforms into a Sculptural Cap Using Steam

The TYPE-O CAP by A-POC ABLE ISSEY MIYAKE begins as a flat woven textile that transforms into a three-dimensional cap through the application of heat and steam. The fabric uses heat-reactive yarns that shrink in controlled areas when steamed, allowing pre-programmed weave structures to activate and reshape the material. This process replaces traditional cutting and stitching, instead embedding the final form directly into the textile itself.
The transformation is achieved through a system called Steam Stretch, developed in collaboration with Nature Architects, where data-driven jacquard weaving determines how each section of yarn responds to heat. Once activated, the fabric contracts in specific zones while remaining stable in others, producing pleats and volume that rise from the flat surface into a sculptural form. The result is a cap that is stored flat, then expanded into its final shape through material behaviour rather than assembly.

Trend Themes
-
Programmable Textiles — Material architectures that change shape in response to stimuli present new possibilities for garments that undergo programmed post-production transformation.
-
Flat-to-form Manufacturing — Manufacturing that encodes final geometry into planar textiles reduces assembly complexity and enables compact shipping and on-demand activation.
-
Data-driven Jacquard Weaving — Weave-level control driven by digital patterns allows precise localized material behaviour and complex three-dimensional outcomes without cutting or sewing.
Industry Implications
-
Apparel and Fashion — Designs that ship flat and achieve tailored volume through heat activation offer reductions in inventory and returns.
-
Headwear and Accessories — Caps and accessories that self-form from flat components enable novel retail presentations and significantly smaller logistics footprints.
-
Medical Textiles — Heat-reactive fabrics that change geometry at activation temperatures can provide conforming supports or deployable protective elements with minimal assembly.
