Evaluation of the use of isotester in measuring cotton fiber properties
MetadataShow full item record
Cotton remains one of the most important natural fibers. Color of the cotton fibers and trash associated with it, are primarily of interest in this research. The IsoTester, a gin based classing instrument, was used for measuring cotton color and trash particles. Schaffner Technologies developed the IsoTester based on the long term vision that Gin-based classing will be implemented by 2020. In addition to Rd and + b, cotton color is also defined in terms of CIE L* a* b* and in this research cotton color measured from IsoTester is compared with the measurements obtained from two spectrophotometers - Hunter Lab LabScan XE and Macbeth Optiview. In addition to this, repeatability and reproducibility of IsoTester is measured.
