Abstract
The invention relates to a method for preparing a spinning fiber raw material by polyester waste spinning microwave heating decoloration aggregates. The method comprises the following process flows: the spinning fiber raw material is prepared by adopting a microwave heating decolorant for gasification and decoloration and a method of crushing granules, so that waste polyester spinning is recycled. The method has simple process, easy operation, no pollution and low energy consumption; can form industrialized mass production.
Description
Technical Field
The invention discloses a method for preparing a spinning fiber raw material by polyester waste spinning microwave heating decoloration aggregates.
Background
As is well known, the waste terylene fabrics are generally buried or burnt with garbage except a small amount of the waste terylene fabrics are directly utilized, which wastes resources and pollutes the environment.
Disclosure of Invention
In order to overcome the defects, the factory adopts a microwave heating decolorant for gasification and decoloration, and uses a method of crushing granules to prepare a spinning fiber raw material, so that waste terylene spinning is recycled.
The specific embodiments are as follows
The technical scheme of the method for preparing the spinning fiber raw material by heating and decoloring the waste terylene fabrics by the microwave is described in detail as follows, but the embodiment should not be construed as limiting the invention.
Example one
Heating the waste terylene spinning decoloring solution to 160 ℃ by microwave, gasifying the waste terylene spinning decoloring solution, and inputting the gasified waste terylene spinning decoloring solution into a sealed metal decoloring tank for waste terylene spinning.
Example two
On the basis of the first embodiment, the decolored liquid and the material are naturally settled and separated, and the gas is pumped into a condenser for cooling and then flows back to the decolored liquid heater for recycling.
EXAMPLE III
On the basis of the second embodiment, the toner pigment in the decoloring solution is precipitated, then the decoloring solution is recycled, and the precipitated toner pigment is dried and then used as a black master batch.
Example four
On the basis of the examples 1 to 3, the decolorized fabric was agglomerated and then crushed into particles of 2mm in size.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
Those skilled in the art will appreciate that the details of the present invention not described in detail herein are well within the skill of those in the art.
