Estimating Functional Relationships Between Fiber Properties and the Strength of Open-End Spun Yarns'

Abstract

Using samples from 96 bales of Texas High Plains cotton, multiple regression techniques were used to select the "best" functional expression for the impacts of High-Volume-Instrument-measured fiber properties on the strength of open-end spun yarns. Results indicate that the most important fiber properties are strength, fineness, and length uniformity. Impacts of fiber properties are typically nonlinear. The micronaire value is inversely related to yarn strength and is best expressed as a cubic polynomial.
