Özet
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 force and elongation, tear strength and light transmittance were compared according to the fabric structure, coating recipes, foam density and the foam coating layer viscosity statistically. And also, air permeability, aged under artificial light and weathering tests were evaluated. 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 acquired at coating recipe 4. As a result, the minimum light transmittance value was 1.04 and the maximum light transmittance value was 1.12 by using coating recipe 4, respectively. Air permeability values of PU foam coated fabrics were in the range of 0-2 mm/s, whereas air permeability value of untreated polyester fabric was measured as 17.36 l/m2/s. Maximum air permeability was obtained in coating recipe 4. The higher air permeability values also gave better barrier to air penetration. The air permeability of coated fabrics were very low due to pore size. The coating material covered the pores of the untreated fabric and restricted air permeability. The color fastness to artificial light of the PU foam coated fabric samples were very good. The fading degree of PU foam coated curtain fabrics was 6. The weathering exposure time of the blue wool scale fabric and PU foam coated fabric samples corresponded to 100 hours. The color fastness to artificial weathering of PU foam coated fabrics in the three coating layers were obtained above 6. Consequently, the low filler content, soft binder ratio and foam density had a positive effect on the mechanical, air permeability, color fastness to artificial light, color fastness to artificial weathering and light transmittance properties of foam coated fabrics.
