| Abstract | ||||
| Wool yarns are dyed with natural colouring matter extracted from Cochineal, Turmeric and Madder and mordanted with different mordants using exhaustion method. Many measurements of the mordanted dyed wool samples after exposure to air & light for different periods of time in one year in urban area (Helwan city) has been carried out. These measurements are change of colour, physical properties (tensile strength, tenacity and elongation) of the mordanted dyed wool samples. Also, the air pollution in Helwan city was studied, through determination of the suspended and deposited particulate matter and sulpher dioxide concentrations. | ||||
