spiralomspunna

Spiralomspunna is a term used in textile theory and speculative design to describe a class of yarns in which a secondary filament is spirally wrapped around a core along a continuous helical path. The resulting yarn exhibits a pronounced spiral ply, a raised texture, and altered surface characteristics that influence drape, elasticity, and tactile quality. The concept is often described as a hybrid of core-spun and wrap-spun yarns, achieved by coordinating twist directions to produce a stable, uniform spiral rather than a simple wrap.

Etymology-wise, the name combines spiral, indicating the helical structure, and omspunna, a form derived from the Swedish word spunna meaning to spin, used here to denote “spun around.” In some sources, spiralomspunna is presented as a hypothetical construct within experimental textile discourse rather than a standard industry term.

Production methods are described in speculative terms as requiring simultaneous core-spinning and wrap-spinning processes. A core filament would carry a secondary filament as it rotates under controlled twist; the wrap frequency and direction create a continuous spiral around the core. In practice, achieving this would demand precise tension control and speed synchronization in machinery, or could be assembled in a laboratory setting with modular spooling systems.

Properties of spiralomspunna yarns include added bulk without significant weight, increased surface area, and a gentle, inherent elasticity. The texture is three-dimensional, often producing a shadowed, ribbed appearance when woven or knitted. Color effects may arise from the wrap filament peering through the core, creating subtle variegation.

Applications are explored in design-focused textiles, decorative fabrics, soft robotics skins, filtration media, and sensor-integrated fabrics where a textured, high-surface-area surface offers benefits. Note: spiralomspunna is not a widely standardized term in conventional textile science and remains primarily within speculative or design-oriented contexts.
