NOVELTY - Preparing anti-chemical functional fiber, comprises: (i) preparing polytetrafluoroethylene slurry; (ii) adding adhesive into polytetrafluoroethylene slurry to improve the viscosity of the slurry, and using a viscometer to test whether the viscosity satisfies the requirements; (iii) pouring the prepared slurry into a slurry groove, and starting a coating device; (iv) soaking the fiber at uniform speed and pulling out the slurry groove to uniformly adhere slurry on fiber surface layer; (v) drying the soaked fiber in an oven, simultaneoulsy and continuously rotating the fiber around a rotating roller to ensure uniform coating of the slurry; (vi) introducing the dried fiber into the roller through the rotating roller, cutting the fiber after satisfying the required quality, changing the roller, and continuously introducing fiber; and (vii) preparing the fiber. USE - The method is useful for preparing anti-chemical functional fiber. ADVANTAGE - The anti-chemical functional fiber has excellent performance, good ventilation property, increased fiber tensile strength, and strong resistance to chemical, acid, alkali and water stain. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an anti-chemical functional fiber, prepared by the above-mentioned method.
