Zinc borate (ZnB) has been used as a fame retardant, a smoke suppressant, and an antitracking agent in several applications. It may show synergistic efects with antimony oxide and metal hydroxides in fre retardant systems. In this work, the efect of ZnB on the fame retardancy of PET (poly(ethylene terephthalate)) woven fabrics was investigated. In order to provide the homogenous application of ZnB to the fabrics, the particle size of ZnB powders was reduced from 9 �m to submicron scale by wet-milling with zirconia balls followed by high shear fuid processing. ZnB dispersion was mixed with low-formaldehyde melamine resin based cross-linking agent and it was applied to PET fabrics by pad dry cure method.
