Abstract:

In order to further explore the fiber fistribution and simulate the fiber arrangement in the sliver, the assumption that fibers left ends were uniformly distributed along the sliver axis in previous researchs is required to verify by any experiment method.Yarn properties is depended upon fiber arrangmnt in the yarn. In previous researches, it was generally assumed that the fibers arrangement in the sliver was random, and the fiber left ends were uniformly distributed along the sliver axis. In this work, an experiment method was used to analyze actual distribution of fiber left ends in the sliver and verify the hypothesis. It can be seen from the results that the hypothesis that fiber left ends arrangement in the sliver were uniformly distributed is reasonable. In addition, the result also indicate that the geometrical natures such as fiber length and linear density have no significant effect on the distribution of fiber left heads in the sliver, as well as the fiber type and the length of carded sliver segment, which provides the basis for predicting sliver properties.

Key words: sliver, fiber arrangement, number of left end, uniform distribution
