Abstract

Dirt appearance on coated fabrics of membrane structures is usually evaluated after subjecting them to outdoor exposure tests for more than one year. Evaluation of dirt-repellent property was carried out by means of colour difference (Delta E) before and after the test using colorimeter. However, there is a problem that the evaluation process takes too long. In order to evaluate the dirt-repellent property of PVC-coated fabrics more quickly, an apparatus for accelerating the dirt process was developed and a series of tests was performed for several dirt-repellent property specimens. The results of colour difference measurements obtained from the accelerated test had sown good correlation with those of the outdoor exposure test.
