Abstract:
1. A method for identifying a nano textile, comprising: 1) determining by appearance whether a textile is a woven fabric or a non-woven fabric, if the textile is a woven fabric, executing step 2); otherwise, executing step 6); 2) detecting the woven fabric using a scanning electron microscopy, setting a plurality of observation areas or observation points, and performing elemental analysis; 3) if results of the elemental analysis of step 2) show that grains on the surface of the woven fabric do not comprise Ti, Zn, or Ag, deeming the woven fabric not to be a nano textile; if results of the elemental analysis of step 2) show that grains on the surface of the woven fabric comprise Ti, Zn, or Ag, executing step 4); 4) determining a crystal form and an average grain size of a finishing material in the grains by using an X-ray diffractometer; 5) if the average grain size of the finishing material is smaller than 100 nm, deeming the woven fabric to be a nano textile; if the average grain size of the finishing material is equal to or greater than 100 nm, deeming the textile not to be a nano textile; 6) detecting the non-woven fabric and measuring the diameter of fibers of the non-woven fabric using scanning electron microscopy; 7) if the diameter of the fibers is smaller than 100 nm, deeming the non-woven fabric to be a nano textile, then establishing observation points of the fibers, and performing elemental analysis; if the diameter of the fibers is not smaller than 100 nm, deeming the non-woven fabric not to be a nano textile; and 8) if results of the elemental analysis of step 7) show that the fibers contain Ti, Zn, or Ag, deeming the non-woven fabric to be a nano textile fused with a finishing material; otherwise, deeming the non-woven fabric to be a nano textile not fused with a finishing material.
