Nanometer selenium yarn structure of cavity combined type

The utility model provides a nanometer selenium yarn structure of cavity combined type, including a substrate and at least four nanometer selenium lines body. The substrate can be organic material orinorganic material to the mode of reeling off raw silk from cocoons is made, at its inside well emptying aperture that is the crosswise that is equipped with, at least four nanometer selenium lines body is respectively around setting up around the outside of well emptying aperture to by the substrate with a plurality of nanometer selenium lines of the integrated into one piece mode cladding body,by means of the here, the function that can gather the gas of leaving a blank through well emptying aperture for the article made by nanometer selenium yarn (if: the clothing), has the efficiency thatkeeps warm and breathe freely, effectively control body temperature, simultaneously, the selenium element of the rethread nanometer selenium line body has the function of anti -oxidant, anti free radical and activation cell to
