  • Recently, problems related to the natural dyeing have been addressed. Severer problems have been posed by the elution at metallic ions and dyestuff tram dyed fabrics. In order to prevent the elution tram the dyed fabrics, it is needed to improve the fastness. Especially, it is the most important measure to improve the fastness to perspiration in terms at human body safety. In this study, we employed chitosan pretreatment method bet ore the dyeing process, anticipating that the pretreatment might improve the fastness. We used Al, Sn, and Cu as mordants and investigated the fastness to light and perspiration of the chitosan treated and dyed fabric specimens. By the chitosan pretreatment, the fastness to perspiration improved, while the fastness to light did not.

  • The purpose of this study was to identify the utility value with material of natural dyeing and to examine the dyeability and antibiosis of fabrics dyed with Solanum nigrum extract. The results obtained are as follows. First, the color tone of dyed fabrics was tinged with from yellow series to green series, in the chrominance the fabric dyed with Fe mordant was showed the highest value. Second, colorfastness to dyeing showed difference as to mordants, but colorfastness to dyeing except for sunlight colorfastness showed the good colorfastness result on the whole. Third, in the test results of antibiosis, the dyed both cotton and silk fabrics showed the very excellent antibiosis effect for bacteria but showed the insignificant effect for fungus.
