A Kyoto chemical manufacturer has created "wood leather" that reproduces the texture of genuine leather, using Japanese cedar, cypress and other woods as the main raw materials, Norikazu Chiba reported for Mainichi Japan.
Photo Insert: The developer, San Nopco Ltd. based in Kyoto's Higashiyama Ward, expects wood leather to be widely used as an "ethical plant-based leather" that does not use animal skin and is environmentally and animal welfare-friendly.
The product is soft despite being mainly made of wood, and has a scent and deodorizing effect unique to wood.
The developer, San Nopco Ltd. based in Kyoto's Higashiyama Ward, expects wood leather to be widely used as an "ethical plant-based leather" that does not use animal skin and is environmentally and animal welfare-friendly.
According to the company, wood leather is made from 55% wood chips and the rest includes a plant-derived polyurethane resin developed independently, resulting in over 80% plant-based ingredients.
It is manufactured by mixing finely powdered wood chips with resin and other materials, and then spreading it evenly over special paper. Generally, wood is strong and hard in large quantities, making it difficult to utilize by softening it.
San Nopco is a subsidiary of Sanyo Chemical Industries, a major firm, and has a unique interface control technology that maintains the uniformity of the formulation.
By taking advantage of this strength, the company has developed wood leather that looks and feels like genuine leather while maintaining flexibility.
The development of the novel leather was triggered by in-house initiatives to find a way to utilize scrap wood generated in the process of manufacturing construction materials.
The company began research in November 2021, and repeated trial production, including adjusting the resin, to improve its practicality. In-house tests confirmed that wood leather is as resistant to abrasion as synthetic leather and has excellent moisture release and absorption.
