The invention discloses nano-ceramic composite fine polypropylene fiber and the processing method. The fiber contains nano-ceramic powder with 12-45 of 300, polypropylene with 250-270 of 300, polyethylene wax with 2-18 of 300 by weight. The denier of the fiber monofilament is 0.5-1.5D, the breaking strength is more than 2.5cN / dtex. We can get the fiber by the step of nano-ceramic powder aqueous dispersion, pre-dispersed precursor, composite masterbatch, composite sections, and high-speed spinning. The nano-ceramic powder is made up of ZrO2, or ZrO2 and ZrC, or TiO2 and Ag+. This type of fiber can be made of various type of textiles, such as sports apparel, underwear, bedding, shirt, socks and so on. The textiles with the function of launch biological waves of energy, anti-UV, anti-bacterial, absorption and barrier the near-infrared. So that to make the textiles have the function of anti-bacterial, energy health, insulation sunscreen, regenerative thermal insulation, dry and comfortable and so on.
