Fabric strength (whichever kind of "strength" we're discussing) is also affected by the weave, coating if any, thread count, and probably other factors, too.


Sure ... but I am not asking exact numbers in thousand different conditions I am not scientist and I will not pretending I am wink
Just some general answer like for e.g. In usual conditions Nylon is 2x stronger then Polyester or is about 15% stronger than Polyester
