Title: | A comparative study of two automated techniques for measuring fiber length | Authors: | Carvalho, M. Graça Ferreira, Paulo J. Martins, Alexandre A. Figueiredo, M. Margarida |
Keywords: | Eucalyptus globulus; Fiber classification; Fiber diameter; Fiber dimensions; Fiber length; Fineness; Image analysis; Kraft pulps; Measuring instruments; Optical measurement | Issue Date: | Feb-1997 | Publisher: | Tappi Press | Citation: | Tappi Journal. 80:2 (1997) 137-142 | Serial title, monograph or event: | Tappi Journal | Issue: | 2 | Abstract: | Measurements from two automated fiber analyzers—Kajaani FS-200 and Galai CIS-100—are compared.The FS-200 measures fiber length and coarseness via an indirect optical method.The CIS-100 measures fiber length and width by analyzing video images of fibers. Length-weighted average fiber lengths for the FS-200 were 10–20% lower than those for the CIS-100. Reference measurements from microscopic image analysis suggest that while the CIS-100 measures length more accurately than the FS-200, it is not accurate enough to measure the width of the thin eucalypt fibers used in this study. Both instruments showed good agreement between weight-weighted fiber length for the whole pulp and weight-weighted length calculated from fiber fractions classified in a Bauer–McNett device. Application: Compares the performance of two automatic fiber analyzers, the Kajaani FS-200 and the Galai CIS-100. | URI: | https://hdl.handle.net/10316/13396 | ISSN: | 0734-1415 | Rights: | openAccess |
