Partial felting processing is one of the processing methods, in which the given patterns are printed on wool cloth by felt-resist paste the main constituent of which is thermo-sensitive polymers before conducting the partial felting process. As a result, the not-printed area becomes felt and the printed area does not become felt so that the material including both felt parts and not-felt parts is produced to provide variations. The partial felting processing has a problem in that the thermo-sensitive polymer to be used is expensive, In the last report, optimization of the felt-resist paste application was performed so that the paste cost was reduced to about one-third compared to the previous method. However, the further cost reduction is necessary for the practical use. Here, optimization of the whole processing method was studied as well as that of the felt-resist paste application, thereby reducing the cost to further approximately 40% compared to the result given by just the optimization of the felt-resist paste application.
