“Regressional” Observations of HVI Fiber Properties, Yarn Quality, and Processing Performance of Medium Staple Cotton

Abstract

Fiber data (USDA) representing six cotton crops (1984–1989) were analyzed using regression and correlation analyses. These data consist of two high volume instrument systems (MCI and SpinLab) fiber properties and corresponding properties measured by traditional systems (the Suter-Webb array method, the Peyer Almeter, the Shirley FMT, the Shirley trash analyzer, and the Pressley strength tester). Different testing systems were compared using bivariate and multivariate analyses, and empirical equations for predicting fiber maturity and short fiber content suggested. The reliability of the results shown in this study is driven by the fact that the data examined involve a wide range of varieties and properties and a large number of observations.
