Abstract：
 The present invention discloses a kind of polyfiber containing structure of Nano carbon tubes which belongs to chemical material preparation technology field.On the forming process of polyfiber containing structure of Nano carbon tubes,at first,weigh carbon nano-tubes,polyfiber and adhensive triacetin mixing,then dispersing by ultrasonic oscillation,adding the composite adhesive into polyfiber,making one end of the carbon nuno-tube felt to or insert the polyfiber through multi procedure such as melting spinning thermal setting etc.and making the other end free outside showing caterpillar shape,the carbon nano-tubes on the each composite fibrils can form nanometer reticular structure mutually and form nanometer filtration channels further.Moreover,the carbon nano-tube possesses effective dasorption capacity ifself and can getter the harmful material between the flue gas fully,also it can be knitted into fiber cloth using for medical mask and preventing SARS.The polyfiber becomes a nanofiltration material of essence significance.
