Filament dispersing unit applied in fiber production process

The utility model discloses a filament dispersing unit applied in a fiber production process, which is characterized in that the filament bundle dispersing unit is added along the trend of a filament bundle between a fiber axis lathe and a cut-off machine, a pair of locating guide rods are vertically arranged at a position of an filament bundle inlet in the filament bundle dispersing unit, multi-stage arc filament dispersing rollers are sequentially arranged from the filament bundle inlet to a filament bundle outlet, and the radians of the multi-stage arc filament dispersing rollers are arranged in a way that the radian of the first stage arc filament dispersing roller is minimum, the radians of following arc filament dispersing rollers increase gradually and the last stage arc filament dispersing roller at a position of the filament bundle outlet is maximum; and the adjacent arc filament dispersing rollers are arranged above and below the filament bundle in a staggering mode. The filament dispersing unit sat
