Title EVALUATION OF DIRT-REPELLENT PROPERTY OF NEW MEMBRANE MATERIALS BY USING TITANIUM DIOXIDE PHOTOCATALYST -Evaluation of stain of membrane materials for membrane structures (Part.5)-

Summary Surfaces of coated fabrics (Class A and Class C membrane materials) were treated with titanium dioxide having photocatalytic effect to enhance their dirt-repellent property.
Evaluation of the dirt-repellent property was conducted by outdoor exposure tests.
The test results showed that the coated fabrics top-coated with titanium dioxide had collected almost no dirt.
The fabrics were by far superior in dirt-repellent property than ordinary coated fabrics without titanium dioxide treatment.
An accelerated dirt process test method for coated materials with a top-coat of titanium dioxide was also studied which has made possible a faster dirt-repellent property evaluation.
