Comprehensive Investigation of NIR Technique in Cotton Fiber Quality Assessment

Near infrared spectroscopy, with an extension to UV and visible region, has been considerably applied for the qualitative and quantitative measurements of key color and physical characteristics in cotton fibers. However, the results have been inconsistent, mostly due to the use of different spectral regions. This work examined and compared the NIR model performances built from various regions for the prediction of cotton color (Rd and +b), physical properties (micronaire, strength, and length indexes), and trash content.  On the basis of results, improvement in reference determination and consideration of other spectroscopic approach were suggested.
