Problems solved by technology

[0003] As we all know, except for a very small amount of existing waste textiles that are used by people using physical methods, they can neither be reused nor directly reprocessed after recycling, and can only be used as landfills or incinerated.
Not only waste land resources but also cause secondary pollution

Abstract

The invention discloses a method for processing PET / PA ferrous alloy color masterbatch by chemically depolymerizing waste polyester textiles. The method comprises the following steps: depolymerizing waste polyester textiles with glycerol residues which have been heated to 260-280 DEG C, and completely filtering out dreg in a solution; adding black carbon black, a compatibilizer and the like, uniformly mixing the above substances with raw materials of different models including PA6, PA66 and PA1010; and performing extrusion and granulation to the special ferrous alloy color masterbatch for PET, PA6, PA66 and PA1010.

Description

technical field [0001] The invention discloses a method for chemically depolymerizing polyester waste textiles and processing PET / PA black alloy masterbatch. [0002] technical background [0003] As we all know, except for a very small amount of existing waste textiles that are used by people using physical methods, they can neither be reused nor directly reprocessed after recycling, and can only be landfilled or incinerated. Not only wasting land resources but also causing secondary pollution. Contents of the invention [0004] The purpose of the present invention is in order to overcome the defective of above-mentioned background technology, fundamentally completely eliminates this backward treatment mode, completely solves the second pollution. [0005] In order to achieve the above object, the technical solution of the present invention is as follows: [0006] The invention discloses a method for our factory to process PET / PA black alloy color masterbatch by chemical...
