Summary: | Disclosed is a process for producing bulky polytetrafluoroethylene fiber with function of catalytically decomposing dioxin, including the steps of mixing bulky polytetrafluoroethylene powder and catalyst powder capable of decomposing dioxin, and then mixing liquid lubricant and thereafter preparing the fiber by processes as follows: extrusion, rolling, longitudinally drawing, sintering stereotype and splitting. The material can be widely used in the treatment of high-temperature tail dedusting and decomposition of emissions. Compared with the previous techniques, the advantages of the present invention are simple process, low cost, no pollution and the like. |
