| This study was conducted to investigate the physical and optical properties of polypropylene and polyester thermal curtains, in which tensile strength, heat reservance and light transmission of two different materials were measured. The results from this study are as follows. 1. The tensile weight of different materials were ranged from 3.4kg to 13.4kg, according to the thickness of materials, but that no difference in the tensile strength was appeared between the two materials. The Elongation of polypropylene materials and the tensile weight and strength of polyester materials were greater than any other materials. 2. The light transmittances of two materials were ranged from 50.3% to 81.7 %, light transmittances in polypropylene were higher by 20-30%,than those in polyester. 3. The heat reservances of two materials were ranged from 18.2% to 41.2%, in which polypropylene showed better performance than polyester. 4. From the results of the test, the polypropylene thermal material was better in elongation, heat reservances and light transmittances, but polyester thermal material was better in tensile strength and light isolation than the other material. |
