| Research Abstract |
Effect of oxidizing bleaching agent on the degradation and decoloring of fabric dyed with metalyzed dye in bleaching process was investigate.The trouble is cause by accelelating of decomposition rate of bleaching agentin aqueous solution.The cause of that was cleared that a metal in the fabric ,especially a copper,catalyzes the bleaching agent. In this study it was cleared that EDTANa -Mg,tannic acid and amino acid surfactant derived from amino acid had a remarkable resisting effect of the degradation and decoloring of dyed fabric in bleaching agent. Pretreating with tannic acid , adding EDTANa-Mg or amino aid surfactant to bleaching solution prevented this trouble.And also decomposition rate of bleaching agent was depressed by these materials. It was assumed that a metal chelated with the dye in the fabric was not pulled out by these materials.
the effect of that was due to an interaction betweeen the metal and these materials, respectively. Based on the spectroscopic measurements, EDTANa-Mg,tannic acid and amino acid is complexes with a copper in the dyed fabric, respectively. Anionic acid surfactant,such as amino acid surfactant,is widely used as detergent in home laundry.It can be applied to bleach the dyed fabric in order to protect the trouble in bleaching process.I think,, threfore, amino acid surfactant is the best materials for practical use.
