Problems solved by technology

However, due to the extremely difficult recycling of polyester-cotton blended fabrics, there has been no domestic enterprise to carry out such work for a long time, and the only application at present can only be used as fillers, etc. Therefore, the recycling and reuse of polyester-cotton blended fabrics has not been well resolved. solve

Abstract

The invention relates to a device for separating cotton-polyester blended fabrics and repolymerizing polyester, which is characterized by comprising a feeding mechanism, an alcoholysis reaction mechanism, a continuous separation mechanism, a pre-polycondensation mechanism and a final-polycondensation mechanism, wherein the alcoholysis reaction mechanism comprises an alcoholysis reactor connected with a discharge hole of the feeding mechanism; a No.1 separation device of the continuous separation mechanism is connected with a discharge hole of the alcoholysis reactor; the bottom of the No.1 separation device is respectively connected with an oligomer receiving groove and a glycol washing groove; a discharge hole of the glycol washing groove is connected with a No.2 separation device; the bottom of the No.2 separation device is respectively connected with a glycol receiving groove and a cotton fiber receiving groove; the pre-polycondensation mechanism comprises an oligomer output pipeline connected with the oligomer receiving groove; the output end of the oligomer output pipeline is connected with a pre-polycondensation reactor; the final-polycondensation mechanism comprises a prepolymer output pipeline connected with the pre-polycondensation reactor; the output end of the prepolymer output pipeline is connected with a final-polycondensation reactor; a discharge hole of the final-polycondensation reactor is connected with a final-polycondensation product output pipeline; and a band extruder is arranged at the tail end of the final-polycondensation product output pipeline.

Description

technical field [0001] The invention relates to a polyester-cotton blended fabric separation and polyester repolymerization device, in particular to a device for separating polyester components and cotton fiber components in waste polyester-cotton blended fabrics and repolymerizing the separated polyester components. Background technique [0002] China is a big textile country. The annual demand for textile raw materials is more than 35 million tons. Due to the shortage of resources, a large amount of textiles and raw materials need to be imported every year. However, the utilization rate of recycled raw materials in my country is extremely low. It is estimated that the amount of waste textiles is nearly 20 million tons every year, most of which cannot be effectively recycled, resulting in a huge amount of waste textiles, which not only pollutes the environment, takes up a lot of storage space, but also causes a great waste of resources. Today, when resource conservation and...
