Thats new to me.
All kevlar I have delt with is yellow in color and does not react the same as Aramid to the hot cutting process.
All aramid I have worked with is white like fiberglass.
I was under the impression that aramid was a sort of coktail of kevlar and other synthetics.
Yes Kevlar is the yellow stuff. An aramid fiber is a usually carbon kevlar weave. Black and yellow.
You can get Kevlar now in Blue,Red,Orange.
