Method of calculating eye opening The main specifications of flat-tatami weaving and twill tatami weaving are open: A A d A： Eye opening (mm) d: Line diameter (mm) ε: Opening rate (%) M: Mesh opening rate: εd M 25.4 A+d A == × 100 flat weaving and twillings are determined by the combination of wire 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 eye openings, and these are calculated as below. ■Please contact us for details other than those listed in the table. ■This is the value of 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 0.42 0.26 0.18 0.14 0.14 0.14 0.14 0.14 0.11 190 85 30 20 20 20 32 165 32 50 508 150 150 0 0 0.150 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0.15
