Embodiment 1

[0056] This embodiment provides a kind of antibacterial color masterbatch, by weight percentage, is made up of following raw materials: antibacterial powder is 15%, colorant is 20%, antioxidant is 0.2%, dispersant is 2%, polyester Powder is 62.8%.

[0057] Specifically, the antibacterial powder is composed of the following raw materials in terms of weight percentage: 70% of bisamino-modified silver-loaded lanthanum phosphate antibacterial agent, and 30% of antibacterial metal oxide.

[0058] Specifically, the antibacterial metal oxide is TiO 2 A mixture of nanometer powder and ZnO nanometer powder according to the weight ratio of 1:2.

[0059] Specifically, the polyester powder is composed of the following raw materials in terms of weight percentage: PET powder is 70%, and PBT powder is 30%.

[0060] Specifically, the coloring agent is a red pigment, a bis(p-chlorophenyl)-1,4-diketopyrrolopyrrole red pigment of the diketopyrrolopyrrole type with the brand name Pigment Red 25...

Embodiment 2

[0077] This embodiment provides an antibacterial color masterbatch, the antibacterial color masterbatch is basically the same as Example 1, the only difference is that the antibacterial metal oxide is different. In this embodiment, the antibacterial metal oxide is TiO 2 Nano powder.

Abstract

The invention provides an antibacterial color master batch and a preparation method of stock solution colored PET antibacterial functional fiber. The invention is prepared from the following raw materials: antibacterial powder, a coloring agent, an antioxidant, a dispersing agent and polyester powder, wherein the antibacterial powder is prepared from the following raw materials: a diamino modifiedsilver-loaded lanthanum phosphate antibacterial agent and an antibacterial metal oxide; the antibacterial metal oxide is TiO2 nano-powder, ZnO nano-powder or a mixture of the TiO2 nano-powder and theZnO nano-powder. The antibacterial powder in the antibacterial color master batch is novel inorganic antibacterial nano-powder; silver ions are reduced into nano-silver elementary substances and loaded on rare earth (lanthanum phosphate nano-powder), and the novel inorganic antibacterial agent is prepared. According to the antibacterial agent, the antibacterial activity of a rare earth compound and the synergistic antibacterial effect of rare earth and elemental silver are utilized, and the excellent antibacterial and antifungal effects are achieved.

Description

technical field [0001] The invention belongs to the field of antibacterial modification of polymer materials, and relates to PET antibacterial functional fibers, in particular to an antibacterial color masterbatch and a preparation method of dope-colored PET antibacterial functional fibers. Background technique [0002] PET fiber, the domestic trade name is polyester. my country is the world's largest producer and user of polyester, but there are problems such as single product and low technical content. High performance, differentiation and functionalization are the future development direction of PET fiber. Textiles are indispensable supplies in people's daily life, and their hygienic performance has also received more and more attention. The widespread existence of bacteria and other microorganisms makes textiles very easy to become a breeding ground for bacteria and fungi during the process of consumption, storage, and transportation, which in turn affects people's hea...
