Heating apparatus with heating line integrated with a soft matrix

The present invention provides a heating apparatus which can be implemented as various articles for keeping human body warm, preventing from cold weather, insulating cold air, etc., e.g., warming clothes, electric blankets, hot compress pads, and curtains for insulating cold air. According to the invention, the heating apparatus includes a soft matrix, a metal yarn and a power supply. The metal yarn is integrated with the soft matrix to construct a loop pattern by a textile process, and has a first end line and a second end line. The first end line and the second end line of the metal yarn are detachably connected to the power supply. When the first end line and the second end line of the metal yarn both are connected to power supply, the power supply supplies the metal yarn with electric energy such that the metal yarn transfers the supplied electric energy into heat.
