利用废弃涤棉混纺纤维回收涤纶
Recycling polyester from waste polyester-cotton blends
摘要
Abstract
The separation process of waste polyester-cotton fiber blends with dilute acid was studied to recycle polyester. The effect of hydrochloric acid concentration, reaction time, reaction temperature and solid-liquid ratio on the separation and recovery of polyester was studied through orthogonal experiment. The results showed that the impact factors order were: reaction time > mass fraction > reaction temperature > ratio of solid to liquid. The optimal conditions were: 10% of hydrochloric acid concentration, 40 g/L of liquid, 95 ℃ and 90 min. The polyester fibers were hydrolyzed into fibrous and cotton fiber were hydrolyzed into small powders after reaction so that the polyester was got.关键词
