천연염료로서 복숭아나무 전정가지의 이용성

Abstract

This study was carried out to investigate the utilization of pruned branch of a peach treeas natural dyeing material. The dyestuff was extracted from pruned branch of a peach tree.we examined the dyeing ability on silk and cotten fabrics. The surface color of silk fabricsdiffered depending on mordants. E values in treatments of mordants ranged from 11.63 to30.86 as compared to non-treatment. Dyeing properties of cotten fabrics were improved witha treatment of sulfate of iron as compared with of non-treatment. The values a increasedwhen the slaked lime and sodium hydroxide were used as mordants, while the values bincreased when copper sulfate, alum and apple vinegar were used. We investigated thesurface colors of silk and cotten fabrics after washing three times. In general, the surfacecolors of silk and cotten fabrics between the treatments of all mordants and non-treatmentwere diminished by the washing. We also investigated the surface colors of silk and cottenfabrics when those were washed and treated by the light after soaking those into various pHsolutions. The surface colors of silk and cotten fabrics were considerably preserved by thewashing, the light and pH concentration. In conclusion, our results suggest that the dyestuffsfrom pruning branch of a peach tree would be useful as a natural dyeing material using theoptimized conditions for silk and cotten dyeing.
