The invention discloses an antibacterial and deodorizing polyester master batch, a preparation method thereof, and polyester fibers. The polyester master batch contains 50-80 parts of polyester, 5-10 parts of water-soluble polyester, 5-20 parts of silver-loaded porous material, 1-5 parts of dispersant, 0.5-1 part of antioxidant, and 0.5- part of coupling agent 1.5 parts; the viscosity ratio of polyester to water-soluble polyester is 5‑20:1; preparation method: firstly, a high temperature kneader is used to melt and knead polyester, silver-carrying porous material, dispersant, antioxidant and coupling agent to obtain polyester Melt; then add the water-soluble polyester into the polyester melt to extrude and granulate, and use the strong shearing action of the extruder to make the water-soluble polyester and the polyester melt evenly mixed and then extruded. The polyester fiber made of the polyester masterbatch, wherein the water-soluble polyester flows to the outer layer of the fiber and can be eluted by hot water, so that the silver-carrying porous material has a microporous structure that is connected to the outside world, deodorizing and antibacterial substances. It is easier to come into contact with bacterial odor, and the antibacterial and deodorizing function is improved. |
