The evaluation of bougainvillea dye source on textile and paper material

Abstract The natural dyes extracted from bougainvillea plant part are applied on cotton as textile material and card sheet as paper material. In this research the fastness properties of bougainvillea dye were determined. Then lab grade mordants such as Potash alum, CuSO4, and SnCl2 were used during dying of this cotton as textile material and card sheet. To find out the quality and effect of this dye ‘and mordants on the textile material and card sheet as paper material, the fastness properties of this given dye is evaluated for the selected textile material and paper material. This properties for Cotton as textile material and card sheet as paper material were evaluated by using standard methods. The colour strength of the dye content obtained through bougainvillea flower part is also determined. Some impotent factors such as extraction and filtration method, extraction time and medium, Pretreatment of fabric material, concentration of mordant and dye solution, etc. are involved in this textile material and paper material dying research work. The given fastness properties for this textile material and paper material are based on the type of mordent used. The suitable mordent and dye combination was determined by fastness properties and strength of the bougainvillea dye on the textile and paper substrates.
