I don't know if it's the right sub-forum but I think it's close.
I'd like to know what is the actual chemical reaction of color fading of clothes under sunlight from initial reactants and the final products. I'd also like to know
where the final products usually go? Do they stay in clothes or leave into the air and if they are bad if inhaled
-
The chromophores generally are still in your clothes, just chemically modified in a way that changes their visible light absorption and reflection properties. There is not one chemical reaction that you can point to, but it is generally the same as what happens when you bleach clothes... except that sunlight is the driver of chemistry. You might do some research on the topic of photobleaching.

Oxidized products, can't really be more specific than that. Photochemistry is complicated.

are the oxidized products usually soluble in the clothes or go away as gaseous form to the air

Usually they stay in the clothes, but are simply less colored than the starting dye or pigment.

Is there any general chemical equation of the bleaching of dye by sunlight?
