Silk Fabric Painted with Natural Dye from <i>Acacia catechu</i> Willd - By Using Flour of Wild Taro (<i>Colocasia esculenta</i> (L.) Schott) as Resist Printing Paste

Abstract

The purpose of this research was to study the white resist printing with colour resistant material from flour of wild taro (Colocasia Esculenta (L.) Schott) and using acacia catechu willd. as natural dye by batik technique. The optimal ratio of colour resistant materials from flour of wild taro were compose of 20% flour of wild taro corm, 36% water, 30% sodium chloride, 10% calcium hydroxide, and 4% vegetable oil. The fixation of painted samples by using hot air at 120 °C for 3 minutes can resist dyestuffs and also easy to remove the flour of wild taro. The pattern at resist printing area of fabrics shows sharpness and whiteness. The colour fastness to light and rubbing results were ranging between fair to good level. However, poor level was obtained from colour fastness to washing, water, and perspiration.
