For this purpose, suitable TPEE for yarn coating was selected by measuring thermal and rheological properties and the yarn coating process conditions were investigated by changing variables such as extrusion temperature, die and nipple dimensions, take-up speed, and core yarn denier. TPEE coated yarns with a diameter of 0.3 and 0.4 mm were prepared, respectively. Tensile properties and cross-section uniformity revealed by a scanning electron microscopy (SEM) of the TPEE coated yarn were analyzed. Among several candidates, TPEE having a melt index of 35 and melting temperature of 153℃ was the most suitable for replacing PVC, and the optimum coating conditions for the TPEE coating yarn were a head temperature of 170℃ and core yarn denier of 420 denier. The selected TPEE coated yarns have enough tensile strength and uniformity to replace present PVC coated yarns, certified by SEM photograph.
