It is provided that a braid which has high dimensional stability even in long-term high temperature storage and which fluctuates little in physical properties with the lapse of time. And it is provided that fishing lines, nets, ropes, and protective covers, and bulletproof materials using the same. A braid comprising a polyethylene fiber or polyethylene tape which has an intrinsic viscosity [] of not less than 5.0 dL/g and not more than 30 dL/g and contains not less than 90% of ethylene as a repeating unit thereof, wherein a thermal shrinkage percentage is not less than 0.45% and not more than 8% under an environment of 80 C. for 240 hours.

An electrical transmission line cable suited for a variety of applications, including as a fishing line in a video fishing system. The electrical transmission line cable has a first conductor and a second conductor forming an electrical transmission line; a jacket containing the first conductor and the second conductor; and a transmission line primary dielectric element separating the first conductor and the second conductor, wherein the primary dielectric element is at least one of textile yarns, fiber yarns, or monofilaments. The electrical transmission line may be in a balanced configuration or an unbalanced configuration.

A yarn which contains a composite yarn composed of a core part containing a short fiber and a sheath part containing a synthetic fiber filament yarn, the core part and the sheath part being integrated via fluff of the short fiber getting between or entangled with the long fibers, the specific gravity of the yarn being adjustable in the range of 1.0 or more, a fishing line containing the yarn, and a method for producing the fishing line. The present invention provides an ideal fishing line which has a strong core-sheath structure, does not allow separation or detachment of the core part and the sheath part, is easy to handle, and also is excellent in strength, weatherability, and water resistance.
