Predicting conducting yarn failure in woven electronic textiles

Endurance behavior of conductive yarns

Various companies are industrializing ‘photonic’ textiles for medical and architectural applications. Here we report reliability testing of photonic textiles based on woven textiles with integrated copper-based conductive yarns used to drive attached LEDs. These textiles were subjected to cyclic mechanical stress tests and the cycle life was analyzed in terms of fatigue. Results show that failu...

Investigation of the Tearing Performance of Fabrics with Various Constructions, Woven from Different Yarn Spinning Systems

Woven Electronic Textiles: An Enabling Technology for Health-care Monitoring in Clothing

In this work we present a technology to integrate electronic devices into textiles at the yarn level. This enables the fabrication of electronic textiles that remain bendable and are therefore suitable for sensor integration into clothing (e.g. to measure physiological signals). This technology is applied to integrate digital silicon based temperature sensors into a textile band which is then c...

Two Robust Fuzzy Regression Models and Their Applications in Predicting Imperfections of Cotton Yarn

Influence of the Dry Woven Fabrics Meso-structure on Fabric/fabric Contact Behaviour

The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...
