Organic zinc antibacterial master batch for spinning, and preparation method thereof

The invention discloses an organic zinc antibacterial master batch for spinning, and a preparation method thereof. The organic zinc antibacterial master batch comprises the following raw material components in parts by weight: 70-92 parts of fiber-grade PBT powder, 5-30 parts of an organic zinc antibacterial agent S16, 0.5-2.5 parts of zinc stearate, 0.1-0.5 part of trimethyl phosphate, 0.1-0.5 part of an antioxidant 1222 and a proper amount of ethylene glycol. According to the invention, the preparation method of the organic zinc antibacterial master batch for spinning is simple, the antibacterial rate is high, the antibacterial effect is lasting, the safety is good, and the thermal stability and spinnability are good when the organic zinc antibacterial master batch is used for preparingantibacterial fibers; and by using the organic zinc antibacterial master batch for spinning, the prepared antibacterial fiber can keep the natural color of the fiber, and the subsequent dyeing treatment is facilitated. 本发明公开了
