The Use Of Near Infrared Reflectance For Evaluating Cotton Fineness And Maturity, Vicki A. Lancaster, Steven M. Buco, Joseph G. Montalvo Jr.

Conference on Applied Statistics in Agriculture

The U.S. Department of Agriculture has proposed to develop Ii new high speed, high volume technique to assess cotton quality. This goal has led us to investigate the feasibility of near infrared reflectance spectroscopy as a technique for evaluating cotton fiber perimeter size and wall thickness, two of the physical characteristics used in the evaluation of cotton fineness and maturity.

In order to isolate the effects of perimeter size and wall thickness, nineteen cotton samples were selected on the basis of their having a nonsignificant correlation between these 2 measurements. The reflectance spectra from 1100 to 2500 nanometers was recorded …
