文摘

4-Amino-double(octadecyldimethyl ammonium chloride)-1,2,4-triazole (ADAC-TZ), a gemini cationic auxiliary with a heterocyclic triazole structure, was designed and synthesized by the method described here and characterized for use in the cold pad batch dyeing of cotton knits. The results show that, for ADAC-TZ, the critical micelle concentration (CMC) is 4.0×10-4 mol/l, the Krafft point is 29.8 °C, the foam height is only 169 mm/5 min, and the solubilization for toluene is 6.67 ml/g, which means that ADAC-TZ exhibits excellent low-foaming, water solubility and solubilization properties. The present research also demonstrates that ADAC-TZ pretreatment can increase the K/S value, dye fixation, and color fastness to washing and rubbing of cotton knits dyed through BES reactive dye cold pad batch dyeing used in combination with the alkaline agent QF-4.
