Abstract :In foam coating, the main factors are the foam density of the coating material and the compatibility among foam structure, the coating material and the fabric surface. In this study, the results of breaking strength, breaking elongation, tear strength and light transmittance testing were compared according to the fabric structure, coating recipes, foam density and the coat layer viscosity statistically. The high yarn density of warp threads per unit length in polyester woven fabric leads to an increase in tensile strength. The best results in tensile strength and elongation at break experiments were obtained at coating recipe 4. As a result, the minimum light transmittance value was 1.0347 and the maximum light transmittance value was 1.12 by using coating recipe 4, respectively. Consequently, the low filler content, soft binder ratio and foam density had a positive effect on the mechanical and light transmittance properties of foam coated fabrics.
