Determining operating variables that impact internal fiber bonding using Wedge statistical analysis methods

In this study, Wedge statistical analysis tools were used to collect, collate, clean up, plot, and analyze several years of operational data from a commercial paper machine. The z-direction tensile (ZDT) Scott Bond tests chosen as representative fiber bond strength. After analyzing thousands parameters, the ones with most significant impact upon ZDT involved starch application method, penetration, amount applied. was found be significantly impacted by formation refining. Final calendering web has also shown an on internal bonding.
