Potential New Instrument to Measure Fiber Length and Diameter

C.K. Bragg and C.L. Simpson


 
ABSTRACT

A prototype instrument for measuring the distribution of cotton fiber length and diameter has been developed. The instrument includes a mechanism for opening and separating cotton so that fibers and trash particles can be passed individually by means of an air stream through an accelerating nozzle containing sensitive electro-optical sensors. The "signature" of each fiber is analyzed as it passes through the nozzle and is subjected to extremely high speed, on-line data analysis to accumulate, tabulate, and characterize the distribution of fiber length and diameter. Currently, the system collects data on 10,000 individual fibers in approximately 60 seconds and is being evaluated in terms of repeatability of measurements and reliability of operation. Future evaluations involving relationships to other fiber properties and spinning quality are discussed.
