Method of calculating the opening of eyes Main specifications of flat-tatami weaving and twill-tatami weaving eyes: A A d A： Opening of eyes (mm) d: Wire diameter (mm) ε: Opening rate (%) M: Mesh opening rate: ε d M 25.4 A+d A = = x 100 flat weave and twill weave are determined by the combination of line diameter and mesh. Mesh' refers to the number of wires or openings counted per linear inch (25.4 mm) of wire mesh. The opening rate is also closely related to the line diameter and mesh, similar to the eye opening, and these are calculated as shown below. ■Please contact us for information other than those listed in the table. ■This is the value from the glass bead test. 310 150 110 86 69 12 24 30 40 50 64 110 200 250 0.6 0.38 0.23 0.18 0.14 0.42 0.26 0.14 0.26 0.14 0 0.0 0 0 0 0 0 0 0 0 0.0.0.0.0.0.0.5 0.5 0 0 5 0.0.0 0 0 0 0 0.0.0.0 0 0 0 0 5 0 0.0 5 0 0 5 0 0.0.0
