Application of Pigment Dye and Resist Printing Paste from Flour of Wild Taro (<i>Colocasia esculenta</i> (L.) Schott) for Printing of Silk Fabric

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 pigment as dyestuffs. The optimal ratio of colour resistant materials from flour of giant taro were compose of 19% wild taro corm, 30% water, 34% sodium chloride, 13% calcium hydroxide, and 3% vegetable oil. The fixation of printing by using hot air at 110 °C for 3 minutes can resist dyestuffs and also easy to remove the flour of giant taro. The pattern at resist printing area of fabrics shows sharpness and whiteness. The colour fastness results were ranging between fair to good level.
