无甲醛耐晒固色剂QJ—02的研制

Preparation of Formaldehyde-free Light-fast Fixing Agent QJ-02

二乙烯三胺在110℃下与氯化铵反应,其产物在120℃时与双氰胺反应,调节pH值=7.5～8,加入环氧氯丙烷,经醋酸酸化合成了QJ-02无甲醛耐晒固色剂。在应用时加入壳聚糖,使棉染色织物的耐晒牢度得到明显提高。与传统的固色剂相比,干、湿摩擦牢度提高了2级,皂洗牢度提高了0.5～1级,耐晒牢度提高0.5～1级,达到了5级,染色织物的色光没有变化。

Diethylenetriamine was reacted with ammonium chloride at 110℃, the resulting product was treated with dicyandiamide at 120℃, then the pH was adjusted to 7.5-8, epichlorohydrin was added and reacting mixture was acidified with acetic acid, to give formaldehyde-free light-fast Fixing Agent QJ-02. When this agent was used, the light fastness of the dyed cotton fabric was obviously improved by adding chitosan. Compared with the traditional process, dry/wet rubbing fastness was 2 levels higher, soaping fastness was 0.5-1 level higher, light fastness was 0.5-1 level higher and reached 5, no color change was observed.
