| Popis: | An electrically conductive textile conducts an electrical current or supplies an electric field to a device. They are usually part of a smart textile system, a textile-based system that exhibits a reaction either to changes in its surroundings/environment or to an external signal/input. Smart textile systems are also known as smart or intelligent textile/garment. Wearing apparel manufacturing companies are proposing smart garments manufactured from smart textiles for outdoor wear, sportswear, lifestyle, and urban life but conductive textiles have not yet reached mass-market consumers as initially forecasted; the endconsumer is not confident to invest in a costly garment with yet unclear cleaning requirements and a potential loss of functional properties after domestic laundry. This thesis studies the influence of domestic washing and abrasion on conductive fabrics and the effects on their surface electric resistance. In addition, it will also be observed the surface change after the abrasion in order to link any physical surface modification with the experimental findings. The specimens to be analysed are conductive warp knitted structure and a non-woven conductive structure combined with a conventional knitted structure forming a 2D conductive composite by lamination; a conductive TPU film laminated with a conventional textile knitted structure and an electronic circuit printed conductive ink and transferred by heat press onto a conventional knit structure; all six 2D conductive specimens have the same conventional ground fabric: a warp knit structure of polyamide and elastane. The conductive 2D materials will be exposed to washing and abrasion tests and their linear surface resistance will be measured at the initial stage of the experiment and compared with their conductive properties during and after the completion of the experimental tests. The work aims to contribute to a better understanding of the effects of domestic laundry and abrasion on the surface resistance of conductive textiles |
