Chip spinning method of photocatalyst chemical fibers

The invention provides a chip spinning method of photocatalyst chemical fibers. The fibers are prepared from, by weight, 80-90 parts of PET chips, 10-20 parts of nanometer titanium dioxide particles,1-2 parts of a dispersion agent, 0.3-0.4 part of an antioxidant, 0.5-1 part of a stabilizer, 0.5-2 parts of a bactericide and 0.5-1 part of an antibacterial agent. The method successively comprises the steps of material preparation, mixing, cooling and pelletizing, secondary mixing and secondary pelletizing and mixing, melting and spinning, and finally, the polyester fibers with photocatalytic performance are obtained; the photocatalyst chemical fibers are simple in spinning steps, reasonable in material utilization and suitable for convenient spinning of factories, new functions are additionally added for traditional chemical fibers, and the current situation is changed that the spinning market is too single; the chemical fibers are good in stability and long in service life, and the chipspinning method allows sp
