It also increases the processing cost of PTFE fiber. If it is mass-produced, first, the equipment cost invested by the processing manufacturer will be twice that of conventional processing PTFE equipment.
Instead, the processing steps will be increased by half. In short, the cost of processing the fiber mentioned in this patent will be doubled, and there is no market competitiveness.

Abstract
The invention discloses a polytetrafluoroethylene superfine fiber processing device and a use method thereof, the device comprises 2-4 air swelling shafts, a stainless steel tank, counter-pressing film licker-ins, stainless steel counter-pressing rollers and a degreasing box, the air swelling shafts are arranged side by side; the stainless steel groove is of a rectangular groove body structure, and the air swelling shafts and the counter-pressing film licker-ins are arranged on the two sides of the stainless steel groove respectively. The counter-pressing film licker-in and the stainless steel counter-pressing rollers are arranged in pairs; the degreasing box is arranged on the side surfaces of the stainless steel counter-pressing rollers; according to the use method, the film belt is arranged on the air swelling shafts, polytetrafluoroethylene emulsion is arranged in the stainless steel groove, the film belt penetrates through the opposite-pressing film licker-ins and the stainless steel opposite-pressing rollers after penetrating through the stainless steel groove, finally enters the degreasing box to be degreased, and then sintering and drafting are conducted. Secondary drafting is performed to obtain a polytetrafluoroethylene drafting belt, mechanical splitting and fiber splitting are performed to obtain fiber bundles, and curling, shaping and cutting procedures are performed to obtain the polytetrafluoroethylene superfine fibers.
Description
technical field [0001] The invention relates to the technical field of polytetrafluoroethylene fiber processing, in particular to a processing device for polytetrafluoroethylene ultrafine fibers and a method for using the same. Background technique [0002] PTFE has excellent physical and chemical properties, temperature resistance -190°C-260°C, has excellent chemical corrosion resistance, and is insoluble in any other chemical solvents except for its own fluoride and molten alkali metal. In recent years, with the development of industry, the emission of industrial waste gas has caused serious air pollution, the control of air smog has been strengthened, and the requirements for control of waste gas emission have increased. Coupled with the increasing number of waste incineration stations. The demand for polytetrafluoroethylene fibers is increasing, and the quality requirements for fibers are also increasing. [0003] The PTFE material has the property of being in a non-li...
