Abstract

In the field of functional textile research, heat-generating fibres to maintain body temperature without unsustainable energy input are of interest. Here, we propose a photoinduced heat-generating viscose fibre fabricated by adding zirconium carbide (ZrC) to the viscose solution. Viscose nonwoven fabrics comprising ZrC-doped viscose fibres were irradiated by infrared (IR) light to measure their surface temperatures, thereby determining their light-to-heat conversion effects. The results show that the surface temperature of the viscose fabric doped with 4% ZrC was increased by almost 40 °C, as verified by ultraviolet–visible–near-IR (NIR) spectroscopy, indicating that the ZrC-doped viscose fibre was significantly increased in photon absorption in the visible-light and NIR regions. The cross-sectional morphology of the viscose fibre was observed using a scanning electron microscope. In addition, thermogravimetric analysis was used to determine the thermal decomposition behaviour of the doped viscose fibres. Moreover, it is noticed that the ZrC-doped viscose fibre has lower moisture regain, potentially increasing the wet strength of the viscose fibre.
