Study on the Characterization of Cotton Fiber Length Distribution

Advanced Materials Research, 2013
In order to characterize cotton fiber length distribution, the probability density function with parameters were used to describe the fiber length frequency histograms. In this paper, four cotton fiber samples (bale, carded sliver, combed sliver and finisher sliver) were selected, and the fiber histograms by weight were measured by USTER AFIS Pro. Two-

Generating Fiber Length Distribution from the Fibrogram

Textile Research Journal, 1996
Theoretical fibrograms were generated from fiber length distributions, and new fiber length distributions were then generated from these theoretical fibrograms for two, three, four, five, and six significant digits using differential and algorithm methods.

Are fiber strength measurements affected by cotton fiber length distribution?

2002
Two experiments were performed to investigate the effect of variations in fiber length distribution on strength measured by different instruments. In these experiments, we assumed that cutting the fibers along their length would not have any effect on the strength measurements.

Modelling of the glass fiber length and the glass fiber length distribution in the compounding of short glass fiber-reinforced thermoplastics

AIP Conference Proceedings, 2014
The use of short glass fiber-reinforced thermoplastics for the production of highly stressed parts in the plastics processing industry has experienced an enormous boom in the last few years. The reasons for this are primarily the improvements to the stiffness and strength properties brought about by fiber reinforcement.

Strength of short fiber reinforced polymers: Effect of fiber length distribution

Polymer Composites, 2008
AbstractIn this study, the prediction of mechanical strength of short fiber reinforced plastics (SFRPs) is made possible by obtaining a Fiber Length Distribution (FLD) efficiency factor, ηFLD, from the formerly known twofold discrete strengthening equation of Kelly–Tyson.

Rheology of natural fibers thermoplastic compounds: Flow length and fiber distribution

Journal of Applied Polymer Science, 2013
ABSTRACTThe presented study investigates the flow length and the corresponding fiber content distribution in the injection‐moulded natural fiber reinforced thermoplastics and its relation to fiber type and processing parameters such as injection pressure, temperature, injection rate and mould tempering by increasing die temperature.

Characterizing wood fiber and particle length with a mixture distribution and a segmented distribution

Holzforschung, 2007
Abstract The length data from 12 samples of wood fibers and particles were described using lognormal and Weibull distributions. While both distributions fitted the middle range of the data well, the lognormal distribution provided a closer fit for short fibers and particles and the Weibull distribution was more appropriate for long ones.

Fiber length distribution and sheet properties

2010
Although fiber length is one of the most often measured property of paper raw materials, the pure effect of it on paper properties is not usually clear. The reason for that is the difficulty to vary only the fiber length while other properties such as fiber width are kept unchanged.

Probabilistic Assessment of Irregularity in Random Fiber Arrays—Effect of Fiber Length Distribution on “Variance-Length Curve”

Textile Research Journal, 1976
The exact distribution and moments are derived for the length (mass) aggregate of fibers to be found within an interval L of a random fiber array as a direct function of the constituent fiber length distribution and the interval size L. The moments immediately facilitate computation of irregularity in terms of the coefficient of variation or the ...

Fiber Length Distribution in Cotton Processing: A Finite Mixture Distribution Model

Textile Research Journal, 2008
This paper introduces a new approach to modeling and parameterizing cotton fiber length distribution. The approach uses finite mixture models to derive a parametric expression of the fiber length probability density function. The model was applied to a multitude of empirical length distributions and proved to adequately parameterize the complex ...
