We are working on “adhesive making”, which is the manufacturing process of Japanese umbrellas.
Natural materials such as tapioca powder, kakishibu,and water are used as the adhesive, and Japanese paper is attached to the bamboo bones.
Kakishibu has antiseptic, insect repellent, and adhesive strengthening effects.
In addition, the amount of water is changed according to the season to make it an adhesive suitable for making Japanese umbrellas.
Although it takes time to mix, it has higher adhesive strength than commercially available adhesives and can adhere firmly.
