Micronaire, maturity and fineness measurements via continuous compression air flow permeability measurements |
摘要 |
Instruments for measuring the gas flow permeability of a fiber sample, particularly a cotton fiber sample; and apparatus and methods employing multiple volumetric compressions to acquire data products for determining "micronaire," "maturity" and "fineness" of the fiber sample. A gas flow permeability testing instrument includes sensors in a gas flow stream enabling the determination of fiber mass delivered to a testing chamber, and a computer outputting a control signal to terminate delivery of fibers to the testing chamber when a predetermined mass set point is reached. A multiple compression fiber gas flow permeability testing device includes a testing chamber into which a fiber sample of known mass is delivered. A movable chamber wall is driven in a substantially continuous manner so as to compress the fiber sample, while a gas flow system determines permeability. A data processing device acquires permeability and chamber wall position (testing chamber volume) data at a sampling rate while the wall is moving.
