Cotton and wool fabrics were mordant-dyed with C.I. direct red 28 (congo red) and copper (II) sulfate. The deodorization abilities of the mordant-dyed samples for ethanethiol were examined using gas detector tubes. The cotton and the wool samples indicated the deodorizing abilities of the following order, respectively: pre-mordant < post-mordant < only copper salt treatment, and pre-mordant < only copper salt treatment < post-mordant. The deodorization rate constants were obtained from the slopes of the lines for the semi-logarithmic plots of the ethanethiol concentration against time. Two rate constants were obtained from the slopes of both the cotton and wool samples for the initial and the following second phases of the deodorization process. The deodorization rates for the mordant-dyed cotton fabrics were of the fast–slow type, while for the wool fabrics they were of the slow–fast type. The deodorization behavior of the mordant-dyed fabrics depended on the type of constituting fiber material for the fabrics. [ABSTRACT FROM AUTHOR] |
