I can see why it maybe would. -too many focused and cancelled bands in the spectrum from the stringent repeating physical structure.
In general the more random the texture, structure and thickness a material is the less modal/phasing exaggerations are created, reflected or absorbed - so natural materials which tend to have faults and variations tend to be superior, however this is "in general". and depending on the wavelengths relationships to the Kevlar weave sizes
-I guess it could produce something more interesting and superior too.
Im sure companies are trying various versions.
