Abstract (en)

[origin: EP4123071A1] In order to provide a conductive composite textured yarn excellent in electrical continuity and wearing durability thereof, there is provided a conductive composite textured yarn including a conductive yarn a and a non-conductive yarn b that are combined by entanglement, wherein the conductive yarn a is a non-crimped yarn and the non-conductive yarn b is a crimped yarn, the conductive composite textured yarn satisfying all following characteristics: crimp rate (%) of conductive composite textured yarn: 10 to 55, and degree of entanglement (entangled parts/m) of conductive composite textured yarn: 20 to 150.
