In order to investigate the linear and quadratic effects of drafting conditions i.e., twist, draft ratio, and roller gauge on the physical properties of several roving i.e., drafting force, tensile strength, elongation, and evenness, statistical methods such as 33 factorial design and multiple linear regression analysis have been used. The draft ratio was the main factor influencing the physical properties of roving. All the drafting conditions influenced the physical properties in a linear manner for all the specimens, but in a quadratic manner, showed partially different results and a carded roving was less significant than other combed roving. Among the physical properties, the elongation was not influenced by the drafting conditions in two-factor interaction. In the multiple linear regression analysis, the twist gave a negative effect on the evenness, but positive on others. The draft ratio and roller gauge gave a positive effect on the evenness, but negative on others.
