The usage of synthetic dye in food and textile industries has generally shown some threatens to the environment and also human. Since then, natural dye has been introduced as an alternative and recently, research in extracting dye from natural fruit is being done in a large scale. In this research experiment, pitaya’s waste was selected as a source for natural dye. However, since pitaya was has high viscosity as one of the properties, it has difficulty to fast on the cloth in textile industries. The ratio of pitaya waste and water is also not known to ensure maximum adsorption on the cloth. In order to tackle this problem, this research will be carried out by using mordant named aluminium sulphate to pretreat the fibres before the dyeing process to ensure the dye fasts on the fibre effectively. Experiments will be conducted to determine the adsorption level by using spectrophotometer and calculations for maximum adsorption will also be done using adsorption isotherm. This experiment was carried out by chemical mechanism. Chemical mechanism refers to solvent extraction using water to extract the dye from the fruit’s peel, the usage of mordant on fabric and also the different concentration of the dye due to the ratio of pitaya waste and water.
