染料浓度在线监测是提升纺织品染色工艺水平的重要手段。根据染料浓度实时检测原理及光纤技术原理,设计开发出了一套染料溶液浓度检测光纤传感系统。在实验的基础上对该光纤传感系统在活性染料溶液浓度检测中的应用进行了系统的研究。结果表明:该系统可准确检测单一活性染料浓度,染色过程中光纤传感系统可实时灵敏地监测染浴中染料浓度的变化。
Dye concentration online monitoring is to improve the level of textile dyeing technology an important means. According to the principle of real-time dye concentration detection and optical fiber technology, a set of dye solution concentration detection optical fiber sensing system was designed and developed. Based on the experiment, the application of the optical fiber sensing system in the concentration detection of reactive dye solution was systematically studied. The results show that the system can accurately detect the concentration of single reactive dyes, and the optical fiber sensing system can sensitively monitor the changes of dye concentration in the dyebath during dyeing.
