Method for recycling waste polyester-cotton textiles

The invention discloses a method for recycling waste polyester-cotton textiles. A recycling polymerization system (1) and a byproduct collection and solvent recycling purification system (2) are involved in the method. The waste polyester-cotton textiles are continuously treated, so that polyester and cotton fibers in the waste polyester-cotton textiles are recycled, the waste polyester-cotton textiles are recycled on a large scale, the requirement of people on the increment of textile fibers is met, the dependence degree of industry on petroleum is reduced, energy is saved, emission is reduced, the environment is protected, the sustainable development of textile industry is promoted, and the circular economy of polyester industry is developed.
