Development of color resistant material from flour of gaint taro (Colocasia gigantean Hook.f.) for resist printing and dyeing
MetadataShow full item record
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 reactive, pigment and natural dyes as dyestuffs. Five formulas of printing pastes were applied to light cotton, thick cotton and silk fabrics by the use three techniques nauely Silk screen (White resist and colour resist methods),stencil and batik. The optimal ratio of colour resistant materials from flour of wild taro were compose of 20 grams flour of wild taro, 32-36 ml. water, 30-34 ml. sodium chloride, 10-13 ml. calcium hydroxide, and 1-4% vegetable oil. The viscosities of printing paste from five recipes were shown in the rage between 559.9-671.9 Centipoise. All five recipes 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 washing, water and perspiration on cotton and silk fabric results were ranging between poor to fair level when using reactive and natural dyes as dyestuff. However, the fastness property of pigment dye shows medium to good level. The colour fastness to rubbing is shown to be in range of 4 to 4-5 for all recipes. The ratings of colour fastness to light in terms of colour change are fair to good (4 to >6).
