【Abstract】 A novel fabric finishing agent containing ATO ultrafine conductive powder is prepared and used for anti static treatment on PET fabric. The technology of the dispersability and stability of ATO ultrafine conductive powder in water have been studied, and the influence of those parameters such as the types of dispersants and the adding amount?pH value and methods of dispersion on the preparation of ATO slurry has also been discussed. Monodispersed ATO slurry can be made by using BN dispersant. While using KH560, keeping pH=9, milling 40?h, the effect of dispersion is the best. The surface resistance of PET fabric treated by the novel finishing agent could be decreased from order of 10 12 ?Ω to 10 10 ?Ω, and the value changed little after being washed 50 times.更多还原
