摘要

In this study, our objective is to investigate the role of fiber denier in a drafting process by measuring drafting force and sliver irregularity for different fiber fineness values and break drafting ratios. The test materials are 100% polyester fibers with 0.8, 1.0, and 1.2 denier fineness values, manufactured in the same way to control the other fiber properties. The break drafting ratios, the other main factor in this experiment, are 1.07, 1.15, 1.20, 1.31, 1.47, 1.57, and 1.76. Although both main factors are significant, fiber fineness interacts with break drafting ratio to affect drafting force and sliver irregularity. The drafting force increases as the break draft ratio increases up to a maximum, after which it begins to drop, indicating a curvilinear relationship. The interaction of fiber fineness and break drafting ratio shows that each of the fineness values reacts differently, and the maximum drafting force occurs at a different break draft ratio for each fiber fineness. In addition, sliver irregularity has a linear relationship with drafting ratio that significantly interacts with fiber fineness.
