Impact of the Fabrication Parameters on the Performance of Embroidered E-clothes

Abstract

THE Two research types of was conductive conducted threads to apply (A1& the embroidering A2) were used. technique Microstructure of fabricating properties e-textiles. of conductive yarns were characterized by energy dispersive X-ray (EDX) and scanning electron microscopy (SEM). Embroidery process was done by computerized embroidery machine. The effects of embroidery parameters such as different stitch type, stitch length and number of embroidered conductive threads on embroidered lines resistance were compared. The best result of conductivity and coating uniformity was obtained when using the type (A1) of coated yarn in straight stitch type with 3 lines of thread with 5 mm stitch length. Due to its low value of resistance (R) 0.83 Ω, while the highest value was 10.66 Ω in the type (A2) conductive yarn in zigzag stitch type with 1 line of thread with 7 mm. stitch length. The A1 yarn type embroidered on a prototype T-shirt to be a connector between the temperature sensor and screen. This embedded system based on conductive thread could find possible application in medical applications: continuous and long-term monitoring of patients in a hospital environment.
