Biodegradable polyester fabric and preparation methods thereof

A biodegradable polyester fabric and preparation methods thereof are disclosed. A biodegradable additive is added to PET (Polyethylene Terephthalate) to allow rapid biodegradation of a textile material in soil, achieving the advantages of environment protection and the like. In addition, different raw materials can be selected for the PET. When recyclable PET bottles, PET packages or polyester fabrics are selected, the waste PET bottles, PET packages or polyester fabrics can be recycled and reused to prepare a biodegradable type of product, which not only reduces economic cost but also achieves multiple advantages such as environmental protection. For the biodegradable polyester fabric, a dye additive can also be added while adding the biodegradable additive to prepare a dye-doped biodegradable polyester fabric, thereby preventing the production of dye wastewater to achieve the purpose of environment protection and moreover, to reduce the preparation cost, with a new biodegradable polyester fabric obtained.
