Title
Standard Test Method for Resistance to Airflow as an Indication of Average Fiber Diameter of Wool Top, Card Silver, and Scoured Wool
ASTM International
Publication Date:
Mar 1, 2005
Scope:
This test method covers the estimation of the average fiber diameter
of wool fibers by use of the
Port-Ar and the WIRA Fiber Fineness Meter instrument, which operate on
the air-flow principle.
Other air-flow instruments have not been tested with this method. The
method is directly applicable
to non-medullated, carded wool and wool top.
This test method is applicable to grease wool and scoured wool after
the samples of such materials
have been prepared as directed in Test Method D 2130.
NOTE 1 - The use of the Micronaire instrument for measuring the
fineness of cotton fibers is
covered in Test Method D 1448.
The assignment of grade for wool and mohair is covered in
Specifications D 3991 and D 3992.
Keywords:
- air-flow
