Measuring Fiber Fineness by Horizontal Air-Flow

Part 2: Measuring Apparatus and Results of Measurements

抄録

An apparatus to measure fiber-fineness by horizontal air-flow has been devised. Several specimens were measured with this apparatus, and the results have been compared with theory.
The comparison has shown that:
(1) The apparatus can measure the weight-fineness of each single fiber, irrespective of the fiber-length or the kind of raw cotton used.
(2) Using the correction coefficient inherent in the apparatus brings an experimental value into good agreement with theory.
(3) The experimental error is about ±0.1 on micronaire reading for fineness below 4. For fineness above 4, the error is slightly larger.
