Evaluation of HVI Measurements by Gin Points

Clarence D. Rogers and David McAlister, III

ABSTRACT

All fiber quality measurements are important to textile manufacturers. With knowledge of fiber properties/characteristics manufacturers can work to improve technical and economic efficiencies. Improvements can be made if sources of variation in quality characteristics can be identified and action taken to reduce or eliminate variation. Thus achieving more consistency in quality measurements. Textile manufacturers have determined that variation in HVI measurements exist within and between gin locations. With this information they have implemented strategies to purchase cottons more selectively. In fact textile firms have begun to look at gin location as a means for controlling variation in cottons purchased and this leads to less variation, more consistency, in cotton mix laydowns. Knowing this information about textile firms, cotton producers and ginners are working to improve variation in HVI measurements within and between bales of cotton. They are also evaluating differences between gin locations and causes for these differences. Twenty-five gins from the Southeast participated in this study. Results from this study show that there is a difference in HVI measurements between gin locations. This is not an unexpected finding. However, the importance of this work is that it lets each gin see how its HVI measurements stack up against the other twenty-four participating gins.
