  The fisrt thing you need to do is rrduce swelling from surfactants. SLES, SLS and AOS tend to swell the fibre and let the dyes leach. Addition of CAPB and other amphoterics will reduce this (I assumed you’re talking about liquid detergents, but maybe I’m wrong). You can also add PVP or similar polymers which help you reduce dye transfer (not leaching but transfer to another cloth). A UV filter will help you with color fading due to UV radiation.
