摘要


本實驗主要是針對目前合成染料對環境和生態的破壞而以環保的觀點,以中藥材紅花、黃連萃取出天然染料色素對織物進行染色來研究其可行性。研究發現兩種天然染料對羊毛以酸性媒染染法染色最具染色性,且因不同的媒染劑的結合而有不同的色相及堅牢度。由結果得知此兩種天然染料的耐水洗、耐昇華牢度、耐日光牢度均優異,大體而言,此兩種染料從產能上、染色性上、牢度上評估後,具有相當之實用性。

For the reason of an ecological and health point , natural dyes are superior to synthetic dyes and extremely welcome possibility in order to spare fossil resources. The object of this paper is studied to the possibility of extracting colourants from Carthani Flos and Coptidis thizoma. Both colourants showed high affinity to wool and cotton produced yellow to brown colour, and the fastness properties of all the dyed samples were in accord with commercial reguirements.
