Preparation,structure and properties of new antistatic polyester fiber

Modified copolyester(MCPET)/inorganic conductive nanoparticle composites were prepared by in-situ polymerization using antimony trioxide,cobaltous acetate and sodium acetate as the catalyst,and the corresponding fibers were acquired by melt spinning.The structure and properties of the polyester pellets and fibers were characterized by SEM,DSC,XRD and TG.It was found that after surface modification the conductive nanoparticles were well dispersed in the MCPET matrix.The crystallization rate and crystallinity of the MCPET were enhanced with the addition of the inorganic conductive nanocomposites.When 1% of the conductive nanopaticles were added,the melt spun fiber had a specific resistance of 2.1×108 Ω·g/cm2 and exhibited excellent anti-static property.
