INTRODUCTION

THEORY

• Jackfruit is the name of a type of tree, as well as fruit. Jackfruit tree belonging to the Moraceae tribe; scientific name is Artocarpus heterophyllus. Jackfruit grows well in tropical climates .

• Trunk jackfruit contain tannins. Tannins are a natural dye pigment dye brown. Tannins also called acid soil (C4H10O9) and a group of plant compounds that are acidic, aromatic, and gives a sense of rough. Form a dark blue or black solution with ferric solution, the alkaline absorbing solution (react) with oxygen (Pudjatmoko, 2004).

Destination

• 1. Knowing the potential of the dye in wood of jackfruit

• 2. Determine the ability of the dye absorption by the wood of Jackfruit

Conclusion

•From experiments have been conducted to get conclusion:

•1. Wood of jack fruit can be used as natural dyes .

• 2. . Time mordanting affect resistant decolouring of cloth

• 3. cotton cloth give better fastness compared with the Semi- silk fabrics.
