The development of an innovative pH-sensor based on colour changing textiles

Abstract
Colour changing textiles or so called chameleon textiles can be used in a whole range of applications since a colour change is an easy, non-disturbing signal which can act as a first signal or warning sign. This paper focuses on pH-sensitive or halochromic textile materials. Standard pH-indicator dyes were incorporated into different textile materials. Firstly, conventional textiles such as cotton and nylon were studied. Secondly, electrospun nano-nonwovens were investigated in which the dyes were added at the start of the production process. The results of the broad screening process showed the feasibility of dyeing cotton and nylon with pH-indicator dyes. In addition to this, electrospinning of polymer solutions with pH-indicator dyes was also achievable. The results prove the possibility of incorporating pH-indicator dyes into textiles. Moreover, the halochromic properties were retained in most of the studied textile systems. It was however noticed that the chromism of the dyes depended on the medium due to the dyefibre interactions.
