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 testinginstrument includes sensors in a gas flow stream enabling the determination of fibermass delivered to a testing chamber, and a computer outputting a control signal toterminate delivery of fibers to the testing chamber when a predetermined mass set pointis reached. A multiple compression fiber gas flow permeability testing device includes atesting chamber into which a fiber sample of known mass is delivered. A movablechamber wall is driven in a substantially continuous manner so as to compress the fibersample, while a gas flow system determines permeability. A data processing deviceacquires permeability and chamber wall position (testing chamber volume) data at asampling rate while the wall is moving.
