As environmental concerns intensify (and in the face of rising energy prices), the need for innovative approaches to reduce our reliance on energy-intensive heating systems becomes increasingly critical. Electrically heated clothing presents itself as a promising alternative solution to keep ourselves warm during the winter months, both indoors and outdoors. These garments could offer an efficient and practical way to provide individuals with the means to stay comfortably warm while simultaneously minimizing energy usage in domestic settings. By reducing reliance on centralized heating systems and focusing on targeted warmth, heated clothing has the potential to significantly decrease energy consumption, mitigate the strain of high energy costs, and contribute to a greener and more sustainable future.

The integration of conductive yarns into the fabric structure of heated garments, known as smart textile knitting, offers exciting possibilities for enhanced comfort and performance compared to traditional electric heating garments (EHGs). However, as this field is relatively new, research is needed to provide future designers with the necessary knowledge and techniques to effectively handle these materials. Conducting research in smart textile knitting will enable designers to optimize yarn selection, stitch patterns, resistance control, and fabric structure. Through this, stable electrical conductivity and high durability of the garments could be ensured. This research will contribute to unlocking the full potential of conductive yarns in weft-knitting, potentially leading to the creation of innovative designs that prioritize both functionality and comfort in heated clothing.

While heated clothing used outdoors may not directly contribute to sustainability, it could provide valuable additional comfort with low energy consumption. Smart textile heated garments could specifically hold significant benefits for individuals with specific health conditions, such as nerve issues like Raynaud’s disease. This is a condition characterized by reduced blood flow to extremities, leading to cold and numb fingers or toes. Smart textile heated garments could provide targeted warmth to these vulnerable areas, helping to alleviate symptoms and improve comfort for individuals with such conditions.

The research conducted on smart textile knitting, despite focusing on silver-coated compound yarns, can be extrapolated to other types of conductive yarns, such as carbon-based yarns. Therefore, the gained knowledge can be adapted by designers while enabling the development of heated garments that utilise alternative materials.
