To use kumazasa’s natural components for Japanese paper
(Challenge of the Sasawashi Development Team)
Their goal is to make use of kumazasa’s natural antibacterial and odor resistant affects to our modern life. We could make “original kumazasa extract” that contains full of natural components by extracting essence from kumazasa grass. But the difficult part is making the product and keeping it’s excellent affects alive in the “original kumazasa extract.”
If we keep it to be natural without chemical treatment, the only way left is to apply original extract directly. But with this way, you will lose the ingredients during the use or by washing the material. Then, the great idea comes out, which is to strain flakes of kumazasa fiber into Japanese paper. Experimental stage proved that the essence of kumazasa’s ingredients stays alive and the functions continue constantly.
Usually, kumazasa after extracted from the plant, decrease its affects considerably because the chlorophylls will be decomposed in a short time period. However, with collaborative study with Dr. Mitsuo Kimura, Ph.d. of technology, the team developed a reformed kumazasa, which is not decomposed by sunbeam, and succeeded to blend it in a Japanese paper. (patent application is underway)
