Hello. I am working on textile (cotton and polyester) and studying the effect of plasma/UV laser treatment on both fabrics.
I am using dye techniques to study the possibility of carboxylic groups formed on the surface after the plasma treatment.
The colour of dyed samples after drying and scanning (using normal scanner) is transferred to Image J software to be analysed and compare the difference in colour shade from one sample to other sample as a function of time. However, I can not under stand how Image J is working, is it measuring the colour concentration or the light reflection? and what units can be used for this?
