"Some confusion here. 7D and 8D refer to the fibres, NOT to the fabric weight. Microfibre fabric using 7D fibres can be quite strong. But air-textured fibres are stronger. Supplex = Taslan; both use air-textured fibres. I LIKE IT."
No confusion. These folks actually know what they are talking about. When some one here says 7D, they mean, SevenD, but every one knows what they mean(well almost everyone). The same goes for the 8D, these are references to specific milled fabrics, not threads. Maybe you would have to spend more time on the forum to catch all these inside references.
