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 modifying PET obtained by chemical depolymerization of polyester waste textiles, purification and polymerization and an extrusion-grade PA6 material to form an alloy extrusion novel material in Central Plastic Union New Material Technology (Hubei) Co., Ltd. The method comprises the following steps: performing depolymerization on the polyester waste textiles byusing glycerin residues heated to 260-280 DEG C, performing filtration, performing decolorization, performing purification, performing polymerization to form the PET, adding auxiliary agents such as acompatibilizer, adding a certain proportion of the extrusion-grade PA6 material, performing uniform mixing, and performing extrusion granulation to obtain the PET and PA6 extrusion special alloy novel material.

Description

technical field [0001] The invention discloses a method of using polyester waste textiles to chemically depolymerize, purify, polymerize into PET, and modify it with PA6 extrusion material to form a new material for alloy extrusion. [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, not only completely eliminate this backward processing mode fundamentally, solve secondary pollution thoroughly. The PET and extrusion-grade PA6 materials obtained by chemical depolymerization, purification and polymerization of polyester waste spinning are m...
