Method of calculating eye opening The main specifications of flat-tatatami weaving and Ayatami weaving: 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 plain weaves 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 wire diameter and mesh, similar to the opening of the eye, and these are calculated as below. ■Please contact us for details other than those listed in the table. ■This is the value according to 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 0.11 190 140 85 30 20 20 20 20 20 20 120 120 1650 1650 15000.50000 0 0 15000000000 0 00 00 000 0
