Howa has been conducting research with the aim of “manufacturing that is friendly to people and the environment.” We don’t use chlorine agents but developed a dyeing technology for jeans “Eco Bleach” which uses the reducing power of sugar (Patent No. 3232010), “Air Wash” which uses ozone (Patent No. 2010650, International patent acquisition in seven countries), etc. ahead of the world and is highly evaluated as a company which has eco-friendly processing technology for the environment.
Better production is possible by integrating analog processing which developed Stone WASH for the first time in the world, production utilizing the newest technology (laser, ozone wash, etc.) and detailed work by hand which was made in Japan.
