Abstract

One of the important requirements before using a dyed fabrics, to ensure the quality of the materials, is the color fastness testing.. There are many objectives of Textile testing methods which are: testing results aid the development of new products or new processes, ensures the right product is shipped to the consumer or customer and that the product meets the customer specifications, to ensure product quality, and to conduct research and developmenThis study compares between the standard test method (AATCC - ISO) for color fastness to washing and crocking for Cotton/ Bamboo blended fabrics dyed with different categories of reactive dyes. The standard test methods for color fastness of washing and rubbing were both taken into consideration in order to preserve the difference in results according to the normal test technique processes. From the results of color fastness properties for laundering using two standard test methods ( ISO & AATCC ) , it can be observed that according to some difference between the procedures steps of both standard ,such as : number of still balls , amount of detergent , temperature and time of washing , some minimal difference were appeared in the results of C.f. to washing ; not exceed than 0.5 degree. Concerning results of C.f.to Crocking of dyed samples showed also little difference that depend on the amount of reactive dye which remain on the surface of Cotton/ Bamboo blended fabric after fixing and washing the samples . Also according to the reactivity of functional group and different dye concentration.
