Abstract

The invention relates to the technical field of fibers, in particular to a multi-stage drafting device for polyphenylene sulfide fibers. Its technical scheme: a multi-stage drafting device for polyphenylene sulfide fiber, comprising several sets of drafting mechanisms, a drafting hot plate is arranged between adjacent drafting mechanisms, and the drafting mechanism includes a mounting frame, and the mounting frame is rotatably connected There are a first drafting wheel and a second drafting wheel, a rotating driving mechanism is installed on the mounting frame, and the output shaft of the rotating driving mechanism is connected with the rotating shaft of the first drafting wheel; the mounting frame of one of the drafting mechanisms is also installed with The output shaft of the reciprocating driving mechanism is connected with a cam mechanism, and the other end of the cam mechanism is hinged with the rotating shaft of the second drafting wheel. The invention provides a polyphenylene sulfide fiber multi-stage drafting device that can keep the shape of the fiber bundle in the drafting process, and solves the problem that the fiber bundle is extruded into a flat shape or is crushed during the drafting process .

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a multistage drafting device for polyphenylene sulfide fibers. Background technique [0002] Polyphenylene sulfide fiber is a special fiber with excellent chemical resistance, high temperature resistance, good flame retardancy, insulation, etc. It is widely used in high temperature flue gas filtration in thermal power plants, steel plants, cement plants, etc. . Generally, the production of polyphenylene sulfide fiber adopts the melt spinning method, that is, the polyphenylene sulfide resin is melt-spun, and then drawn, crimped, and cut. At present, the drafting of polyphenylene sulfide fibers mainly adopts three or four drafting methods. [0003] The invention patent with the patent application number CN201911363997.6 discloses a production method for preparing high-performance polyphenylene sulfide fibers by one-step drawing, including: spinning: adding PPS resin to spinning eq...
