Fluorescent Coloration of Polyurethane Sports Fabric and Its Fastness Properties

In order to develop high fastness fluorescence color on polyurethane fabrics used for sports, three fluorescent dyes having alkyl substituents were investigated. The quantum yield of the dyes was obtained the lowest value for Fluoro Yellow B (0.421) and higher ones for Fluoro Yellow A (0.782) and C (0.830). However, with regard to the fluorescence intensity on fabrics, Fluoro Yellow B showed stronger value than other two dyes. Durability of the dyeing against five organic solvents was appeared in the order of hexane, ethanol, benzene, acetone, and chloroform. Fastness to washing and rubbing was excellent for the three dyes showing ratings 4-5. Fastness to dry heating which had been worried about with regard to sublimation was good exhibiting ratings at least 4. Practically acceptable result was achieved in terms of light fastness which was one of the biggest drawback of fluorescence, showing ratings 3 for Fluoro Yellow B and 3-4 for Fluoro Yellow C except for rating 1 for Fluoro Yellow A.
