| Outline of Final Research Achievements |
To develop the teaching materials of home economics, we studied two safe and simple dyeing methods.In the studies of the dyeing with onionskin, we made clear that food additives can be used in mordanting instead of chemical reagents. We also studied the dyeing method to effectively use the onionskin. As a result, we had proposed a method that can be dyed with 25% of the standard amount.
In the studies of the dyeing with clay pigment, it was found that the kind of clay pigment, fiber and liquid pH gave greatly influence to dyeing. When the type of the buffer solution was different, the dyeing behavior was different, even in the same pH.
