<p>A banner or flag is made from a non-densely woven textile panel with two or more types of weave with high and low density zones. At high weight per unit area fabric the panel is less air permeable than at lower weights. The permeability arises from perforations formed by the insertion of rods. The low density mid-zone (20) is separated from higher density zones (22, 24) : The fabric is a woven polyester with an original specific weight of 95-105 g/m2.</p> |
