- absolute micron retention
( See Micronic Filter Cloth )
In both types of dutch weave the sum derived from multiplying the number of weft wires
in a given measurement by their diameter, results, in theory, in a specification with no
open space. Because the wires are driven together during the weaving process, the aperture
size cannot be calculated in the normal manner.
There are two methods by which the aperture size can be determined: bubble point
testing and glass bead testing.
