The most common method for the fabrication of colorimetric textile sensor based on halochromic dye is conventional dip dyeing. However, dip dyeing has various drawbacks such as significant dye leaching after wet process, high energy consumption, and environment-hazardousness. Comparatively, UV-induced dyeing method is gaining interest for its lowered energy costs, improved wash-fastness and wide applicability. Herein, we developed bromocresol purple dye with photoactive group, and fabricated colorimetric textile sensors based on the dye via LED-UV grafting method. In addition, we investigated color change property after exposure to ammonia as well as wash fastness of textile sensors. The dye and textile sensor showed drastic color difference with high sensitivity to ammonia and superior wash durability. |
