Abstract
A suspended sand dragging fiber and a preparation method thereof, the method including: dispersing nanoparticles into a first solvent, adding a coating agent and a flexibilizer to the first solvent, and stirring and aging to obtain a surface treatment agent; adding a surfactant to a second solvent, adding alkyl polyether siloxane to the second solvent after the surfactant is dissolved in the second solvent, and stirring to obtain a finishing agent; transferring the surface treatment agent to a sizing trough of a sizing machine, sizing polyester fibers using the sizing machine, and drying and curing to obtain surface-modified fibers, and diluting the finishing agent to obtain a finishing agent solution, and treating the surface-modified fibers with the finishing agent solution to obtain the suspended sand dragging fiber.
