    Hi

    I'm looking for some insight into a problem I am trying to solve.

    So I have a fabric which has been dyed. It is required to be placed in a gas oven at 190C. Unfortunately this is changing the colour of the material making it slightly lighter.
    I am unable to alter the temperature of the oven as it is required to be set this way.
    Previous data shows that using an electric oven did not produce this colour degradation at the same temperature.

    So I am wondering if the CO or NO2 from the gas oven is somehow causing a chemical reaction with the material at this temperature and thus altering the colour?
    As a test I have placed some material in an electric oven at 190C and did not observe any colour alteration.

    Any advice would be great!

    Kind regards

    Anthony

    No idea but are your colours water soluble? Remember water vapour is a product of gas combustion, could it be water being absorbed by your dyes and diluting them?

    Interesting. I'm not sure I can get hold of the data regarding the dyes used, however I could set up some kind of experiment to test whether water absorption dilutes the colour.
