Embodiment 1

[0009] A method for preparing PBT raw materials by chemical reduction of polyester household textile waste leftovers according to the present invention, first crushing polyester household textile leftover wastes into 100mm fragments, and melting them with butanediol heated at 220°C.

Embodiment 2

[0011] On the basis of Example 1, the dregs in the dissolved liquid were filtered clean.

Embodiment 3

[0013] On the basis of Example 2, the solution obtained by filtering the dregs is more finely filtered with carbon powder, and the pigment etc. in the solution are filtered out.

Abstract

The invention discloses a chemical reduction method for preparing PBT raw material from Dacron domestic textile fabric leftover materials. After the Dacron domestic textile fabric leftover materials are heated and dissolved by using butanediol, filtration and then decoloration are carried out, BHBT is purified, and a catalyst is added to polymerize PBT.

Description

technical field [0001] The invention discloses a method for preparing PBT raw materials through chemical reduction of polyester home textile scraps in our factory. [0002] technical background [0003] As we all know, the existing polyester household textile scraps can neither be reused nor directly reprocessed except for a very small amount of them being used by people using physical methods. They can only be used as landfills 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 present invention heats and melts the scraps of polyester household textiles with buta...
