本不研究係將利用士林染料在室溫下以二浴冷軋浸吸捲置的方式使純棉、織物上色，並改變還原劑用量、鹼劑用量、染料濃度、壓吸率、捲置時間，以進一步探討其染色後的上色性及強力與染色堅牢度等變化。由實驗結果得知，分子小的染料較分子大的染料上色性來的更好，另一方面，隨著時間增加，染料上色性亦隨之提高。
In this study, the cotton Fabrics were dyied by two process cold pad batch with vat dye. Changing the concentration of reduction agent alkali agent dye ration of pad and batch time to investigate the effect of dye-uptake physical properties light fastnessand and water fastness. We get conclusion that the dye of IK type was get better dye-uptake than other types On the other hand with the time increase the dye-uptake also increase.
