Breeding for improved yarn quality: Modifying fiber length distribution

Industrial Crops and Products, 2013
Abstract For the last two decades, cotton breeders have used HVI (High Volume Instrument) as their primary and often sole source of fiber quality data when making plant selections. Fiber data generated by Advanced Fiber Information System technology is also now available to plant breeders, and provides additional information on length characteristics

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.

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 ...

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-

Fiber length distribution effects on the fracture of short‐fiber composites

Polymer Composites, 1990
AbstractThe effect of fiber geometry on the fracture behavior of short glass fiber‐reinforced nylons was examined. In particular a comparison was made between conventional short‐fiber composites (with feedstock made by an extrusion process) and the newer pultruded feedstock materials which have longer fiber length distributions but larger fiber ...

Influence of Fiber Length Distribution on Strength Efficiency of Fibers in Yarn

Textile Research Journal, 2002
The tensile and tear strengths and hence the durability of a cotton fabric are greatly influenced by the length and strength of cotton fibers in addition to the fabric structure. This is so because fiber length to a large extent determines yam strength, which ultimately contributes to fabric strength.

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 ...

Reconstruction of the cotton fiber length distribution from a High Volume Instrument® fibrogram

Textile research journal, 2022
Cotton fiber length is one of the most critical parameters of fiber quality for ring-spun and air-jet-spun yarns. Currently, two of the most common instruments for testing cotton fiber length are the USTER High Volume Instrument (HVI) and the USTER ...

The Effect of Fibers’ Length Distribution and Concentration on Rheological and Mechanical Properties of Glass Fiber–Reinforced Polypropylene Composite

Journal of Industrial Textiles, 2021
This article aims to investigate the effect of dispersion and uniformity of fiber length distribution on the rheological and mechanical behavior of polypropylene reinforced with short glass fiber.

Length distributions of hemoglobin S fibers

Journal of Molecular Biology, 1990
Electron microscopy of sickle cell hemoglobin fibers fixed at different times during gelation shows an exponential distribution of fiber lengths, with many short fibers and few long ones. The distribution does not change significantly with time as polymerization progresses.
