摘要
Mordant-dyed cotton and wool fabrics were prepared with direct and basic dyes, and copper(II) sulfate. The deodorization rates for ethanethiol by the mordant-dyed samples were measured by gas detection tube method and gas chromatography of flame photometric detection. The deodorization processes had two phases. For mordant-dyed cotton samples, the deodorization rates of the initial phase were fast, and of the successive second phase were low (fast-slow type). To the contrary, the mordant-dyed wool samples indicated slow-fast type of the deodorization rates. Comparison of the deodorization behaviors of the cotton and wool sample fabrics revealed the large difference in the state of copper ions adsorbed by the fabrics.
