摘要
织物光致变色是指在某一波长光线照射下,着色织物的颜色发生变化,而光线消失后又可逆地恢复了原来的颜色。其中,螺噁嗪类化合物是一类稳定性和抗疲劳性优良的光致变色材料。试验制备了具有光致变色性能的螺噁嗪材料N-甲基-3,3-二甲基-9'-二氯均三嗪基螺[2H-吲哚-2,3'-(3H)萘并(2,1-b)(1,4)噁嗪],并用红外光谱对其结构进行表征。采用该螺噁嗪材料对棉织物进行超声染色,探讨染色工艺条件对光致变色性能的影响,确定的优化工艺条件为:染液质量浓度0.8 g/L,染色温度50℃,染色时间20 min,焙烘温度100℃,焙烘时间15 min。
A reversible change of color of photochromic fabric occurs upon exposure to light. Spirooxazine material,N-methyl-3,3- dimethyl-9 ＇-dichloro-s-triazine group spiro [2 H-indole-2 ＇-[3 H] naphtho [2,1-b][1,4] oxazine],a kind of photochromic dye with good stability and durability,is prepared and characterized by FTIR,and then is applied to cotton dyeing under ultrasound condition. The dyeing conditions are optimized according to K /S value and photochromic properties of cotton dyeings,and the optimum dyeing process is dyeing at 50 ℃ for 20 min with 0. 8 g /L of the spirooxazine dyes,and curing at 100 ℃ for 15min.
