Abstract

This application relates to a method for recycling polyester waste, which relates to the field of recycling polyester waste, and aims to solve the existing problem of poor cleaning effect on polyester waste. This application includes the following steps: S1: packing and transporting polyester waste To the cleaning site, first unpack and pulverize the polyester waste; S2: clean the pulverized polyester waste; S3: dry the cleaned polyester waste; the cleaning operation in the step S2 includes the following steps: S2 ‑1: Float washing of crushed polyester waste with flotation solution; S2‑2: Heating and rinsing of flotation washed polyester waste with alkaline water rinsing solution; S2‑3: Rinsing of polyester waste after rinsing Perform an autoclaved wash. The application can well improve the cleaning effect on polyester waste, so that the recycled product of polyester waste has excellent performance.

Description

technical field [0001] The application relates to the field of polyester waste recycling, in particular to a method for recycling polyester waste. Background technique [0002] Polyester is a general term for polymers obtained by polycondensation of polyols and polyacids. It mainly refers to polyethylene terephthalate (PET), and also includes linear thermoplastic resins such as polybutylene terephthalate (PBT) and polyarylate. It is a class of engineering plastics with excellent performance and wide application . However, the use of polyester materials also produces a large amount of polyester waste, and as people's awareness of energy conservation and environmental protection increases, people gradually begin to recycle polyester waste, thereby reducing environmental pollution. [0003] Existing publication number is the Chinese patent of CN101289766, discloses a kind of recycled polyester staple fiber, is to adopt waste polyester bottle, sheet material, the polyester blo...
