Disclosed is an antibacterial anti-ultraviolet multifunctional chemical fiber: dissolving a soluble metal salt and a high-molecular complexing dispersant into water to prepare an aqueous solution; adding into a polymer monomer; reacting under microwave or hydrothermal action to obtain a polymer monomer containing a multifunctional nano oxide; adding the polymer monomer with a polymer, a catalyst, an initiator, a stabilizer, and the like into a polymerization reaction kettle; and carrying out esterification, polycondensation, or copolymerization to obtain a polymer melt, and carrying out spinning or strip casting and granule cutting to obtain an antibacterial anti-ultraviolet multifunctional chemical fiber yarn or master batch slice. According to the present invention, by generating nano metal oxide in the monomer in situ before the polymerization reaction, small particle sizes and dispersibility of the nano metal oxide are ensured while subsequent spinning and weaving are not influenced; the provided antibacterial anti-ultraviolet multifunctional chemical fiber has efficient and durable antibacterial anti-ultraviolet functions and is free of metal ion precipitation, effectively overcomes the problems in the prior art of precipitation discoloration caused by using silver ions, and functional singleness, and is safe and environment-friendly in use. |
