Analysis of electrical and comfort properties of conductive knitted fabrics based on blending ratio of silver-coated yarns for smart clothing

In this study, the relationship between functionality and comfort of conductive fabrics for smart clothing is investigated by examining changes in mechanical, electrical, properties knitted based on blending ratio yarns. Hence, flat same structure are manufactured using polyester silver-coated polyamide Subsequently, their weight, thickness, tensile strength, strain, bending rigidity, breathability, surface measured, cool touch feeling, resistance, electrical heating performance evaluated. Because strength specific gravity a yarn high, with an increase its ratio, rigidity increase, whereas strain decreases. terms properties, air permeability increases as increases, because pores fabric increased structurally owing to However, water vapor transmission rate remains unchanged. Meanwhile, roughness does not change significantly wale direction; however, it course direction increases. The recoverability from compression decreases, work This implies that can be compressed easily but less likely recover compression. Changes property show hand value altered insertion yarn. improved increasing particular, even only 33% yarns, extremely good obtained, is, low sensitive resistance due stretching, 48°C. Therefore, conventional yarns instead improve wearability when applying clothing.
