Nanoparticle-embedded heat-generating cloth and method for fabricating threads thereof

Abstract

A nanoparticle-embedded heat-generating cloth comprises a fabric including a plurality of threads each having a plurality of spaces, and a plurality of heat-generating nanoparticles filling with the spaces and enclosed by the threads. The fabric generated by the present invention can be fabricated into various heat-generating clothing for users to wear. Since the heat-generating nanoparticles fill with the spaces and are enclosed by the threads, the drop amount of the heat-generating nanoparticles can be decreased to the minimum, or even no heat-generating nanoparticle drop is generated during washing of the clothing. In other words, the heat-generating clothing of the present invention can have prolonged lifetime.

What is claimed is: 
     
         1 . A nanoparticle-embedded heat-generating cloth, comprising:
 a fabric including a plurality of threads, wherein each of the plurality of threads includes a plurality of spaces; and   a plurality of heat-generating nanoparticles filling with the plurality of spaces and enclosed by the plurality of threads.   
     
     
         2 . The nanoparticle-embedded heat-generating cloth according to  claim 1 , wherein the heat-generating nanoparticles are made of a material selected from a group consisting of tourmaline, zinc oxide, titanium oxide and magnesium oxide. 
     
     
         3 . A method for fabricating threads of a nanoparticle-embedded heat-generating cloth, comprising steps of:
 letting a plurality of particles collide mutually to form a plurality of heat-generating nanoparticles; and   heating and melting a yarn material at a temperature of 200-240° C., and fully fusing the melted yarn material with the plurality of heat-generating nanoparticles to form a plurality of threads through a spinning process.
