Abstract Smart textile is considered to be a new trend that can revolutionize the functionality of clothing. In the present study, the effect of stitch types on the electric conductivity of embroidered woven fabric with conductive yarns is investigated. Two types of yarns were used to make durable, flexible and even washable layer of electric conductive yarns embroidered on the surface of woven fabric. This makes it an important factor that affects the final performance of the product. The first type of yarns was made by continuous filament of stainless steel while the second type is a spun yarn of stainless steel. type of stitches namely running stitch was selected. Therefore, the aim of this work is to optimize the embroidery circuit design, stitch density, yarn type, fabric type and used needle according to the type of conductive yarns to achieve the optimum functional garment performance. For that sixteen trial experimental designs of four factors at two levels (conductive yarn type, stitch density, fabric type and hook type) were applied. Moreover, the samples were highly conductive, it can relate the dc-conductivity to the structure and any treatment or modification that have been done on samples measured before washing, and after five washes. Results show that there is a significant difference of the electrical conductivity values before wash and after 5 washes for cotton samples with p-value = 0.024539, but there is no difference between the electrical conductivity values before wash and after 5 washes for wool samples. Finally determine the effect of different pe pH solutions on electrical conductivity and results show that there is no significant difference for the electrical conductivity values before perspiration and after acidic, neutral and alkaline PH. This means that the embroidered conductive yarns were made from high stainless steel metal. |
