藍染是古老且世界性之天然染色技法，使用藍靛染料（天然染料）為染材。天然染料相較於合成染料，天然染料有較佳之環境親和性，也無環境及健康等負面問題。臺灣藍染歷史悠久，荷蘭人從17 世紀中葉導入木藍開始，歷經3 個世紀多的歷史演化變遷，直至21 世初的現在，臺灣藍染已存在臺灣將近400 年。臺灣藍染是由製靛工序、建藍工序及染色工序所建構而成。以現代科學的眼光定義製靛工序及建藍工序，它們即是「生物技術」，但此古老生物技術的效率不彰。本研究以環境永續發展及人類健康為前提，建構臺灣藍染製靛及建藍工序量化作業程序，以提升製備效率，如此不僅有利於人類生存環境之永續發展，也將有機會提升客家文化的應用價值及藍染相關產業的推進。

Indigo dyeing is an ancient and worldwide natural dyeing technique that uses indigo dye (natural dye) as a dye material. Compared with synthetic dyes, natural dyes have better environmental affinity and no negative environmental and health issues. Taiwan’s indigo dyeing has a long history, and the Dutch introduced Indigofera tinctoria in the mid-17th century. After more than three centuries of historical evolution, Taiwan’s indigo dyeing has existed in Taiwan for nearly 400 years until the beginning of the 21st century. Taiwan’s indigo dyeing is constructed by indigo production process, indigo reduction process and dyeing process. Indigo production process and indigo reduction process are defined from the perspective of modern science, they are “biotechnology”, but the efficiency of this ancient biotechnology is not good. This study is based on the premise of environmental sustainability and human health, and constructs the quantitative operation procedures of indigo production process and indigo reduction process of Taiwan’s indigo dyeing to improve the preparation efficiency. This is not only conducive to the sustainable development of the human living environment, but also create opportunities to enhance the application value of Hakka culture and promote the development of indigo dyeing–related industries.
