The invention relates to a crimped and deformed terylene conductive filament and a manufacturing method and an application thereof. The crimped and deformed terylene conductive filament is obtained byperforming crimping and deforming processing on the terylene conductive filament, and is characterized in that the crimp shrinkage rate is 15-60%, and the crimp stability is 40-90%. The process flowof the deforming processing is as follows: the conductive fiber protofilament is heated and plasticized by a deformation hot box, cooled by a cooling plate, twisted and untwisted by a false twister, shaped, added with a network, oiled, wound, inspected and packaged. The crimped and deformed terylene conductive filament is beneficial to subsequent blending weaving processing or is independently used for weaving, so that a soft and bulky human experience effect can be shown, and the crimped and deformed terylene conductive filament can be widely applied to 1) tranquillization and hypnosis, 2) blood circulation improvement, 3) electrostatic removal, 4) dust removal and filtration, 5) mariculture, 6) freshwater culture, 7) preparation of negative ions containing water/air, 8) electric heating,9) low-pressure conducting wires, and 10) signal transmission.
