季铵盐莲茎秆在棉织物练染中吸附活性染料的研究

摘要

Lotus stalk was modified with cationic etherifying agent, its structure was characterized by infrared spectral. The influence factors of modified lotus stalk about reactive blue M-2GE adsorption were investigated. The best optimal modification process is as follows: lotus stalk 4 g, cationic etherifying agent 50 g, water 200 g, pH=9, and reaction temperature 85 ℃ for 5 h. The optimal of modified lotus stalk absorbing reactive blue M-2GE is: bath ratio 1︰50, pH=5, and adsorption temperature of 80 ℃ for 40 min. The adsorption process meets the soaping conditions of one bath scouring and dyeing process. Lotus stalk modified with quaternary ammonium salt shows self cleaning property in reactive dyeing residual liquid.%为了配制练染一浴环保型精练剂，合成了阳离子醚化剂改性莲茎秆，并对其结构进行红外光谱表征，探讨了季铵盐莲茎秆对活性蓝M-2GE吸附的影响因素。结果表明季铵盐莲茎秆制备的最佳条件为：莲茎秆4 g、阳离子醚化剂50 g、水200 g、pH=9、反应温度85℃、反应时间5 h。季铵盐莲茎秆吸附活性蓝M-2GE的最佳条件为：浴比1︰50、pH=5、吸附温度80℃、吸附时间40 min，该吸附条件满足练染一浴工艺皂洗条件。季铵盐莲茎秆对活性染料染色残液具有自清洁功能。
