“…In Liu’s study, a knitted heating fabric was developed through combining silver plating compound yarns with staple fiber spun yarns [ 228 ]. However, metallic textiles usually have large friction force and weak cohesive force, which may lead to slippage or separation in the spinning process [ 240 ]. Also, the low elastic recovery rate and low bending resistance of fine metallic fibers may even result in breaking and falling off from the fabric.…”
