Abstract
Opuntia Ficus has been an epiphyte plant since it was introduced in Cheju island as an ornamental plant two hundred years ago. And now it is grown as many as it is designated to local souvenir No.35. The fruit of this plant contains red-purple sap, which is due to be used in coloring clothes.This study aims at confirmation of use possibility as eco-friendly dyeing stuffs on extract from opuntia ficus fruits and contributing to the practical use of natural dyeing. Thus this study was investigated the dyeability of extract from opuntia ficus fruits on the silk fabric. Antioxidants were used ascorbic acid, L-cysteine, prophyl gallete. After dyeing, K/S and dye fastness were measured. The results were as follows; Maximum absorption band of extract from opuntia ficus fruits was 534.5nm. The appropriate dyeing condition was bath ratio 50:1, dyeing temperature 30℃, dyeing concentration 50%, dyeing time 50min, pH 3, concentration of all antioxidants 3%. Addition of antioxidants brought increase of K/S value. And K/S value and dye fastness had the greatest value when ascorbic acid was added
