In a former life (1980s), I used to import the cheapest knitted cotton gloves from China and sold them to my Swiss customers. The manufacturer washed them after manufacture (the yarn was bleached before it came into his factory). I did Contaminometer tests on each batch we received and the ionics were surprisingly low (forget the figure but I think it was less than 1 µg/cm² eq. NaCl). The price was so low that customers could afford to throw them away whenever they became visibly contaminated or snagged (their main disadvantage as they shed fibres when this happened). These were very popular and I think I must have sold tens of thousands of pairs with many repeat orders. Can't remember why I stopped - think it may have been because the manufacturer upped his minimum order to a million pairs or something like that! However, I must point out that ESD is not an issue with cotton as the fibre is naturally hygroscopic and charges will leak away in no time, even in a dry atmosphere, from moisture absorbed from the underlying skin. In a few cases, customers used them as an under-glove with ESD-proofed plastic gloves on top for improved comfort.
