Fabric containing a conductive yarn and apparatus for making the same

Abstract

A fabric and an apparatus for making the same are disclosed. A conductive yarn has a non-conductive core thread and a fine metal thread wound around the surface of the non-conductive core thread. The fine metal thread is guided by an apparatus to wind around the surface of the non-conductive core thread in a spiral form. The apparatus has a base station, an axle on the base station, and a spool set on the axle for twisting the fine metal thread. The core thread passes through the center of the axle, and the axle is driven by a power to drive the spool to rotate, thuds winding the fine metal thread around the surface of the non-conductive core thread so as to form an elastic and flexible conductive yarn.

AI Technical Summary

Benefits of technology

[0019]According to the above description and embodiments, the conductive yarn and the apparatus for making the same of the present invention have the advantages as following:

[0020]1. The apparatus for making a conductive yarn of the present invention exerts an upward pull on the non-conductive core thread for winding the fine metal thread around the non-conductive core thread to form the conductive yarn of the present invention. The conductive yarn of the present is not easy to be broken and is soft and flexible.

[0021]2. When the fine metal thread wound around the core thread in the spiral form is conducted with electricity to generate heat, the conductive yarn of the present invention has well elasticity for thermal expansion and contraction.

[0023]4. Compared with conventional heaters, the power consumption of the conductive yarn of the present invention is reduced by more than 45%.

Problems solved by technology

In addition, hot air moves upward so people could not feel warm immediately, which result in taking larger amount of electricity and time to raise the temperature of the air in the space to a certain degree.

Moreover, the air in the space is dry, accompanying with thundering noises, due to blowing and flowing of hot air.
