Antistatic finishing is normally done with a hygroscopic or ionic chemistry that works well until the air is dry — which is exactly when static is a problem. A conductive network in the fabric behaves differently: it does not depend on humidity. That is the reason to look at graphene here, and it is also where the honest caveats start.

Because it would not mean anything for your fabric. Surface resistivity of a finished textile depends on add-on weight, fibre type, fabric construction, whether the coating forms a continuous network across the yarn crossings, and how it is cured. Two mills applying the same dispersion at the same concentration to different constructions will measure different values.
What we can tell you is what governs the result:
We will not quote one, because it depends on your add-on, construction and cure. What we supply is a characterised graphene dispersion and the guidance that below the percolation threshold you get no network at all. Establish the value in trial.
A conductive network does not depend on humidity the way an ionic antistatic does, which is its main advantage. Wash durability depends on your binder system and must be measured on your fabric.
The dispersion is applied as a coating rather than being spun in, so fibre type matters less than construction and pick-up. Cotton's higher absorbency usually means higher pick-up, which you should account for.
Raman spectrum, BET at 500-700 m2/g and an SEM image, all of which we supply with the sample. Graphite powder does not produce those numbers.
