How They Produce Natural Indigo
Pure Blue Japan used a traditional dyeing technique from Tokushima Prefecture called “Awa Shoai Dyeing”. As most denim is dyed with synthetic indigo , Pure Blue Japan decided to use natural indigo to make their jeans more unique and one-of-a-kind. The characteristic of Pure Blue Japan’s natural indigo-dyed denim is the deep indigo colour that cannot be expressed with synthetic indigo, and the unique color fading that sets it apart from other denim.
In general, yarns used for weaving denim fabric are called “rope dyeing” and the core of the yarn is not dyed, leaving the middle of the yarn white. However, natural indigo dyeing, the yarn is dyed slowly by craftsmen using a technique called kase-zom (hank-eye) penetrating the indigo to the core of the yearn. For this reason , Pure Blue Japan’s natural indigo-dyed jeans do not show high contrast whiskers fades, but instead show a truly unique fading.
