Investigation of Dyeing Properties of Pine Wood Samples with Allium Cepa That Pretreated by Willow Extract

Abstract

– In this work, willow (1 kg) pieces were allowed for 21 days at room temperature and 27 numbers of pine wood samples were mordanted for 12 h in willow extract. These mordanted samples were dyed with dyestuff obtained from dried onion shell by boiling in deiyonized water, at pH=4, 7 and 8 using premordantation, together-mordantation and last-mordantation methods. The solutions of CuSO4·5H2O, AIK(SO4)2·12H2O and FeSO4·7H2O were used as mordanting agents. Dyeing conditions and other characteristics were determined. In generally, with high fastness authentic colours were obtained
