I am interested to know the generic name of chemical that can be used for such purpose. Also interested to know what function such chemical perform? Do they work similarly like Anti-Back staining or in other way.
Is it possible to use just dispersing agents stable at higher temperature to remove the unfixed Disperse dyestuff from cotton?

So many points in your question, by the way please kindly find the following references, Hope they can help you in these regards:
1- https://www.sciencedirect.com/topics/chemistry/disperse-dyeing
2- The influence of pH adjusted with different acids on the dyeability of polyester fabric ( article which is attached )
3- Clearing of dyed poly(lactic acid) fabrics under acidic and alkaline conditions ( it is attached too),
4- https://patents.google.com/patent/US4286961A/en
Reducon-ACD (Conc) is a reduction clearing agent available in powder form. Reducon-ACD (Conc) removes unfixed disperse dyes in acidic medium from polyester and its blends with polyacrylonitrile. It is applied in cooling dyebath of acidic medium. It is water soluble thus make easy dosing process.
