Abstract

With the increase of technological developments, technological products have become a necessity in every second of our lives. Because of this need, wearable technologies have emerged by combining technology with textile products. Wearable technologies are used in different fields such as healthcare, military applications and entertainment by means of their convenience. Another concept developed from the term of wearable technology is the concept of electronic textiles. In the production of electronic textiles, electronic components are included in textile products or these components are directly produced in textile forms by making the textile products conductive. Different materials such as conductive yarns, conductive fabrics, conductive coatings and conductive adhesives can be utilized to obtain conductive textile structures. Among these conductive materials, conductive yarns are one of the most preferred conductive textile products, either for the purpose of forming a texture or surface, or for use in connection paths. In this study, the criteria which are effective in the purchase of conductive yarn have been determined firstly. These criteria are; metal ratio, conductivity, flexibility, biocompatibility, mechanical strength, washability, usability in the machine for production and price criteria. Then, it was requested from 10 experts, who purchases conductive yarn in their company, to score the determined criteria according to the importance level in the yarn purchasing process. Collected data were evaluated using DEMATEL method which is one of the multi criteria decision making methods. As a result of the evaluations, when the criteria weights are sorted according to importance level; usability in the machine for production is the most important criterion in the system with 17% criterion weight. This criterion is followed by conductivity (16.86%), biocompatibility (13.66%), metal ratio (11.60%), mechanical strength (11.54%), price (10.77%) and flexibility (10%, 69) criteria, respectively. The least important criterion is the washability criterion with a weight of 7.8%. When the network structure and interplay of criteria are examined, usability in the machine for production criterion is the most influencing criterion whereas this criterion is influenced by no criterion. It was concluded that while the washability criterion had no effect on any criterion, it was affected by all criteria.
