untwistable
Resistant to coiling
Untwistable describes something that cannot be twisted or untwisted—either because the material resists twisting or because once twisted, it cannot be reversed.
The word appears in technical contexts describing cables, cords, or fibers: an untwistable steel cable.
It can also describe figurative tangles: The plot became so convoluted it was untwistable.
