Safety belts are the life saving product for the persons working on high rise buildings, factories etc. The objective of this research work is to investigate the effect of various constructional variables on the properties and performance of safety belts. The samples were prepared using different denier of polyester filament yarn. Box-Behnken design of experiments with 3 factors and 3 levels has been used for the sample plan, the statistical analysis and the optimization. The results showed that the number of warp yarn is the most influencing parameter for strength and elongation of safety belts followed by the weft density and warp denier respectively.
