Discussion on the Changes of Fiber Length Distribution in Stretch-breaking Process

摘要

In this study the changes of fiber length distribution in stretch-breaking process are investigated. Based on the deduced probabilistic properties of the integral function, the mean length, length irregularity and short fiber content after the process can be obtained in terms of the probability density function of fiber length before the process and the distance between rollers. It can be concluded that an increase in the stretch-breaking gauge increases the fiber mean length and length irregularity in the stretch-breaking process. Compared with the fibers before the process, the mean length of the treated fibers becomes shorter, and the short fiber content increases correspondingly, but the length irregularity decreases, which is significantly helpful for the yarn forming process.
