Abstract: A method for separating and recycling a waste polyester-cotton textile by a hydrothermal reaction catalyzed by an organic acid, comprising the following steps: dividing a waste polyester-cotton textile into fragments and dispersing in an aqueous solution system of the organic acid catalyst to obtain a mixed system; in a high-pressure reactor, heating the mixed system to 110˜180° C. so that cotton fibers in the waste polyester-cotton textile undergo a degradation reaction for 0.5˜3 h to obtain a mixture; and filtering the mixture by a sieve, washing to obtain a polyester fiber aggregate, and then filtering the remaining portion by a filtration membrane in vacuum so as to obtain cotton fiber fragments after washing. Embodiments of the present disclosure may provide advantages for the separation, recycling and reuse of waste polyester-cotton textiles. For example, the catalyst used during processing is derived from nature and is biodegradable.
