Influence of Surfactants on the Dye Transfer Inhibition Reaction of Orange II with Rice Hull Peroxidase

Abstract

An influence of surfactants and the prepared model detergent on the transfer inhibition of Orange II was investigated by measuring the decoloration rate constants and the dye transfer to nylon fabric using peroxidase derived from rice hulls (RPO) . When SDS and Brij-35 (cmc×1.5) were added to the decoloration system, the decoloration rate constant was lower than that of RPO single system. However, it is possible to inhibit the dye transfer in RPO-surfactant system at 20°C. At 60°C, the dye transfer to the nylon fabric was greatly affected by the presence of surfactants, there was no transfer of Orange II to nylon fabric. Moreover, the fabric was examined about dye transfer in the presence of RPO and the prepared model detergent, the system completely inhibited the dye transfer to the fabric. RPO-surfactant system is efficiently reacted to the dye transfer at 20 or 60°C.
