HCI research has demonstrated that textiles have interactive potential, with the ability to transform or self-shape, whether through material, structure, or the addition of non textile elements. Many materials for developing interactive or animated textiles – textiles which change during use – are fossil fuel-based, require electricity for activation, or are only available in small quantities. In this pictorial we present our exploration of high-twist linen yarn as an actuator material in woven textiles. Through experimental design research, we have defined key parameters affecting use of the material, and identified combinations of material and structure producing contrasting textile movement. The resulting woven textiles may be activated by spraying with water, or in high humidity, and the actuation is repeatable after drying, offering multiple modes of interaction. We offer proposals for HCI applications for the animated linen yarn, alongside a guide to facilitate producing and designing animated woven linen textiles.
