Objective:
The objective of the research is to study fundamental issues on the relationship between the cotton length distribution of the original sample and the length distribution measured from a tapered beard. A component of the objective is to study the feasibility of including a new length parameter characterizing short fibers in the cotton classification system.

Approach:
Conduct a fundamental study of the fiber length distribution of the tapered beard and revisit the basis theory of fibrograph by use of computer simulation. Use AFIS to compare length distributions of fibers obtained from the rotary sampler with raw cotton. Compare results for the lower half mean length (LHML) parameter obtained from HVI test results with those from AFIS using the same set of cottons. Continue to establish reference cottons as research benchmarks for short fiber content measurement. Study the relationship of short fiber content (SFC) values defined in the U.S. by 0.5 for selecting specimen samples for HVI length testing along with a new method for accurately measuring the fiber length distribution in a completely visible beard.
