Abstract

The PAN spinning solution was chosen as the spiral spinning research object. Laminar flow theory was used to straighten and align macromolecules, and spiral spinning needles were used to control the spiral twisting of straightened PAN macromolecules. The internal spiral arrangement of PAN nanofibers became more compact as the helix number of spinning needles increased. The TEM (transmission electron microscope) was used to photograph the motion trajectory of TiO 2 (titanium dioxide) nanoparticles in nanofibers, which directly confirmed the feasibility of the spiral spinning principle. SEM (Scanning Electronic Microscopy) observations revealed that the appearance of the PAN nanofiber membranes changed to some extent under spiral physical technology. The analysis of the tensile and bursting properties of PAN nanofiber membranes demonstrated that the structure of the nanofibers changed significantly after spiral spinning. The pore structure, electrical resistance, and antibacterial properties of PAN nanofiber membrane all reached optimal values at the optimal helix number of spinning needle.
