13. Study on the Optimal Sealing Technological Regime for Making Sport Wears from Waterproof Fabric

The article focuses on the separate and simultaneous influences of sealing technological effects: air temperature, sealing speed, roller pressure and nozzle pressure on resistance to water penetration, ultimate tensile strength, the adhesive strength of seam sealing after washed in processing sportwears made from waterproof fabrics. In this research, we used the analysis of variance method for two-elements case, planning method orthogonal experimental variety of factors, Microsoft Excel 2013 and Design Expert 11.0 software to process and analyse experiment results. The result which is to identify sealing technological elements has important effects on resistance to water penetration, ultimate tensile strength, the adhesive strength of seam sealing after washed. The result of this study is an useful guide in the actual production to improve the quality of links in order to save time and costs in the actual production in sportwear garment enterprises as well as Seam tape supplier in general and at TNG Investment and Trading Join Stock Company in particular.
