Recycled Fiber Bleaching Overview, 2002 Fall Technical Conference
This POWER POINT presentation is an overview on Recycled Fiber Bleaching and lowering Quality Grades, by stretching the furnish.
With its primary focus on
furnish and final quailty, a closer examination of both the Oxidative and Reductive processes of bleaching utilizes these key factors:
- Chemistry
- Conditons
- Sequence
- Stages
Dependiing on furnish and the final quailty, ultimately, determines each of these key factors and their appropriate involement in the bleaching process.
You will then understand how, with today’s available bleaching processes, the furnish can be stretched to lower quailty grades.
