Abstract

The invention discloses blended yarn containing polytetrafluoroethylene fiber and a preparation method of the blended yarn. The blended yarn is prepared from, by weight, 5-80% of polytetrafluoroethylene fiber, 20-95% of flame-retardant fiber and 0-5% of conductive fiber. The blended yarn containing polytetrafluoroethylene fiber is prepared by adding a certain proportion of conductive fiber, preprocessing the raw material before spinning, adding an antistatic agent for being still standing for at least 8 hours for antistatic processing, strictly controlling the technological conditions of all the procedures in the processing process, and controlling the temperature and relative humidity of the carding, drawing, roving and spinning procedures. The severe static problem during spinning of polytetrafluoroethylene fiber is effectively solved, and yarn quality is ensured.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a blended yarn containing polytetrafluoroethylene fibers and a preparation method thereof. Background technique [0002] Polytetrafluoroethylene fiber, called fluorine fiber in China, is a synthetic fiber made of polytetrafluoroethylene (see fluororesin) as a raw material, which is cut or fibrillated after spinning or making a film. The fiber strength is 17.7~18.5cN / dtex, and the elongation is 25%~50%. In its molecular structure, the volume of fluorine atoms is larger than that of hydrogen atoms, and the binding force of fluorine-carbon bonds is also strong, which plays a role in protecting the entire carbon-carbon main chain, making PTFE fibers have excellent chemical stability and excellent corrosion resistance. Compared with other synthetic fiber varieties; the surface of the fiber has a waxy feel and a small friction coefficient; the actual use temperature is 120-1...
