This paper investigated optimum process conditions of coating yarn for awning fabric. For this purpose, thesimulation for processability and yarn quality using SPSS statistics package was carried out, and PP/TPO and PET/PVC coatingyarns specimens were made with variation of extruder temperature and feed speed of core yarn on the yarn coating machinefor examining simulation result. It was revealed that optimum coating conditions of PP/TPO 1000d coating yarn were extrudertemperature 150℃, and core yarn feed speed 400~500m/min. Mechanical property and thermal shrinkage of PP/TPO coatingyarn made at this conditions were best and core evenness rates of these coating yarns by yarn compression tester were alsosuperior, which was certified by SEM photograph. In addition, these experimental results were coincided with simulationresults. It was found that, in PET/PVC coating yarn, yarn physical properties between 1500d and 1200d coated yarns werenot shown any difference, and core evenness rates of these coating yarns were superior. It revealed and concluded that thesesimulated coating conditions are applicable to production field.
