| Abstract: | Antibacterial zeolite was subjected to ultrafine grinding and surface modification to produce antibacterial masterbatch for PET fiber. The zeolite particles with average size 1 μm can be produced from 13X zeolite by the technology of combining jet mill and sand mill or gravitational sedimentation. The antibacterial zeolite with compound metallic ion superior to AGZ-330 made in Japan in bacteriostasis ( D value) can be obtained by ion exchange process in liquid phase . The surface modification and covering treatment were conducted for zeolite by using silane coupler and dispersing agent. The dispersion of zeolite ultrafine particles in PET matrix was evaluated by SEM. The DF value of antibacterial masterbatch was 0. 187 MPa · cm2/g. PET fiber added with 5% antibacterial masterbatch yielded smooth spinning process. |
