羊毛繊維の酸化染料染色における細胞膜複合体の役割

抄録

The effect of a modification of cell membrane complex (CMC) on the color developed by oxidation dye reaction of three precursors with a coupler was investigated. From the results of dyeing in the presence of ascorbic acid and ethylenediaminetetraacetic acid (EDTA), it was found that the dye uptake of the wool samples modified with 98-99% formic acid decreased apparently compared to that of unmodified wool sample. The decreased extent of their uptake was dependent on the extent of modification of CMC. However, if unmodified and CMC-modified wool samples were dyed with the preformed dyeing system, the dye uptake of all the modified samples ware approximately same as that of unmodified sample. Also, it was found that the mechanically pulverized cortex cells seem to be inactive to dyeing with both oxidative dyeing system and preformed dyeing system. Consequently, it is assumed that not only the CMC regions play an important role as accumulation regions of the finished dye, but also any components of the intercellular material take strongly part in color formation on the wool fibers as catalyst.
