Abstract

In this experiment, tomato is extracted to obtain the natural colorant of its own which the polyester fabric was dyed with under the condition of pH value 6.5 by adding various mordant individually. The K/S value, relative dye-take-up rate and dyeing fastness are discussed in this article. The results show that, the higher the pH value of the lycopene extract, the greater the absorbance value. And, the largest absorbance value can be obtained when the acetone is used among the extraction solvents tested. Finally, the polyester-fabric samples dyed with the mordant ferrous sulfate can have the highest relative dye-take-up rate, and also have good rubbing fastness grade 4 and washing fastness 5.

摘要

本實驗以番茄為天然色素之萃取材，在pH6.5條件下，添加不同媒染劑對聚酯織物染色，並探討其表觀濃度(K/S值)、相對上色率及染色堅牢度等。結果顯示，番茄紅素萃取液之pH值調得越高，吸光度值越大；當萃取溶劑為丙酮時，吸光度值為最大；硫酸亞鐵之媒染聚酯織物相對上色率為最高，耐摩擦堅牢度均達4級以上，耐水洗堅牢度均達5級。
