Sifat Tahan Luntur dan Intensitas Warna Kain Sutera Dengan Pewarna Alam Gambir (Uncaria gambir Roxb) Pada Kondisi Pencelupan dan Jenis Fiksator Yang Berbeda

Abstract

Tannins are complex compounds in plant tissues when treated with certain metal ions to form a specific color so it can be used as a dye in textile products . The color strenght of the fabric produced is determined by the condition and temperature at the time of dyeing . The purpose of the research is to determine the effect condition of dyeing and the selection of the desired fixer produce variations in color , colour strenght values and good fastness. Dyeing is done in the heat (60-70{º}C) and at room temperature (27-30{º}C) , with fixer Al2(SO4)3 ( alum ) , CaCO3 (lime) and FeSO4 (lotus) The results showed that the direction is quite varied colors on silk ranging from yellow , golden yellow , brownish red , brown , moss green to blackish green . The optimum conditions obtained in heat dyeing (60-70{º}C) , the fixer CaCO3 which produce of colour strenght is higher ( the value of K/S ) of 19.174 and fastness to washing 40°C , light the sun and rubbing is good to excellent ( 4-5 )
