摘要：

The response of a sliver to steady-state drafting over a wide range of draft ratios and the response of a sliver to a tensile-like separation test are shown to be divided into two regions of behavior. At low drafts or strains, associated with a tensile force buildup, the principal mode of sliver deformation is by fiber extension producing a Poisson-like consolidation of the sliver cross section. At higher drafts or strains, the principal mode of sliver deformation is by sliding of the fibers relative to one another. The response of a sliver to low drafts or strains corresponds to the behavior of a continuous, extensible material. Fiber uncrimping extension is found to be a major variable controlling sliver behavior and the shape of the drafting force vs draft curve in the low draft range. © 1969, SAGE Publications.
