The Study of Punica Granatum Absorption Behavior on Wool Fibers by Using Spectrophotometric Data

Abstract

In This work, the absorption behavior of Punica granatum or Anar as Iranian natural dye on wool fibers was studied by using spectrophotometer data of dye solution. Initially, wool yarn were scoured and mordanted with Alum. Then wool yarn was dyed with anaar as an Iranian natural dyes. In next stage, the wastewater of dye bath was reused for wool dyeing. For spectrophotometry study, the absorbance spectral of dye solution was measured by spectrophotometer. Then, the absorbance values of dye solution were used to determine dye concentrations in the wastewater of dyebath and absorption by wool fibers. The result indicated that the exhaustion and shade of dye solution changed by variation in Alum concentration. The hue of wastewater differs from initial dyebath.
