HVI Measurements of Short Fiber Content

H. H. Ramey, Jr.


A Short Fiber (SF) content measurement developed by Zellweger Uster for High Volume Instrument (HVI) systems is being evaluated. The software program was installed in 10 HVI lines in the USDA-AMS Quality Assurance unit and SF was measured on all checklot samples, beginning September 19, 1997. For 83,547 samples processed through December 16, 1997, the reproducibility within plus or minus 1.0 was 77.0 percent. The SF measurement is highly correlated with other length measurements. There are differences in results levels among the 10 lines being used. Means of bringing all lines to a common results level is being addressed.
