Determination of the Effect of Recycling Treatment on Pulp Fiber Properties by Principal Component Analysis

บทคัดย่อ

The effect of recycling treatment on properties of hardwood bleached kraft pulp fibers was determined. Even though the morphological and physical properties of fibers were affected by recycling, there were no significant changes in most of the properties. Therefore, an application of principal
component analysis for determining the effect of recycling treatment was attempted and demonstrated in this research. This application could graphically demonstrate the difference between never-recycled and recycled fibers as well as that between the recycled fibers themselves. Furthermore, the results of the analysis could also usefully reveal the correlation between properties of fibers.
