    Cotton fiber strength is an important quality characteristic that is directly related to the manufacturing of quality consumer goods. Currently, two types of instruments have been implemented to assess cotton fiber strength, namely, the automation oriented HVI and the laboratory based Stelometer. Each of them has unique merits and correlation between the two strength readings was reported to be relatively low. In this study, both HVI and Stelometer strength readings were corrected by respective micronaire values in both quotient (strength/micronaire) and product (strength*micronaire) forms, and the modified strength readings were found to have a much improved relationship. Also, the relationship might suggest a way to determine the suitable samples in creating the NIR model for predicting the cotton strength effectively.
