Preparation of composite ink of reactive dyes/colloidal microspheres and its application

以一氯均三嗪活性染料和聚(苯乙烯-甲基丙烯酸)(P(St-MAA))纳米微球制备活性染料/纳米微球复合型墨水,喷印在真丝织物上构建光子晶体生色结构。应用扫描电子显微镜、紫外-可见近红外光光度计、3D视频显微镜和旋转流变仪研究复合型墨水中P(St-MAA)纳米微球浓度、活性染料浓度、墨水表面张力和黏度对真丝织物上光子晶体结构及其生色效果的影响。研究结果表明:调节P(St-MAA)微球质量分数为15. 0%,一氯均三嗪活性染料墨水体积分数为5. 0%,控制墨水表面张力介于53～65 mN/m,黏度不超过3. 70 mPa·s时,复合型墨水可以在真丝织物喷印构建颜色鲜艳的光子晶体结构色图案。

The reactive dye/nanosphere composite ink was prepared with monochlorotriazine reactive dyes and poly （styrene-methacrylic acid） （P（St-MAA） ） nanospheres as the main materials, and the base color and structural color of photonic crystals on silk were synchronously fabricated by jet printing. The scanning electron microscope, ultraviolet-visible spectrophotometer, 3D video microscope and rotary rheometer were applied to study the influences of concentration of P （St-MAA） nanospheres, concentration of reactive dyes, ink surface tension and viscosity on the photonic crystal structure and the related structural color on silk fabrics. The results showed that, the reactive dye/ nanosphere composite ink could be used to fabricate brilliant structural colors of photonic crystal structure on silk fabrics by jet printing under the following condition conditions： mass fraction of P（St-MAA） nanospheres 15.0% , mass fraction of monochlorotriazine reactive dye 5.0% , surface tension of ink 53-65 mN/m and viscosity no more than 3.70 mPa ·s.
