Problems solved by technology

[0003] In the prior art, the toner is added after the foam material is poured into the drum dryer to complete the drying process, and the toner is put into the drum from the feeding port half an hour before discharging, and then the drum is started to shake evenly. The toner added by this method has poor adhesion, and a large amount of toner volatilizes during discharging, causing quite serious air pollution and a large waste of toner. At the same time, the amount of toner attached to the foam is reduced, which affects product quality.

Abstract

The invention relates to a toner adding process and aims at providing a novel toner adding process for improving the coloring effect of soaking material, improving the toner utilization rate and avoiding the waste and air pollution caused by toner volatilization. The toner adding process has the advantages that soaking materials without drying treatment and the toner are added into a drum drying machine at the same time, in addition, powdery solid wax is added, and the drum drying machine is started.

Description

technical field [0001] The invention relates to the technical field of melt spinning, in particular to a process method of adding toner to waste polyester regenerated foam in a drum dryer. Background technique [0002] In the production process of melt spinning, because the raw materials are recycled foams processed from recycled waste polyester, the source batch numbers of the foams are complicated, resulting in unstable fiber color and failing to meet product requirements. Color powder is added to improve product color. [0003] In the prior art, the toner is added after the foam material is poured into the drum dryer to complete the drying process, and the toner is put into the drum from the feeding port half an hour before discharging, and then the drum is started to shake evenly. The toner added by this method has poor adhesion, and a large amount of toner volatilizes during discharging, causing quite serious air pollution and a large waste of toner. At the same time, ...
