I use 100% cotton flannel pads. Easy to make if you have basic sewing skills, though I got mine from Glad Rags years ago, I think. I don't have personal experience on the herpes issue, but it sounds like cotton pads would work well for you in general.
I bled a LOT the first few days after birth though, so no normal pads would have helped. I used the giant hospital "diaper" pads for the first week or so. You might want to google ultra absorbent cotton pads and/or how to make them if contact with synthetic fibers is really problematic for you.
