It looks very similar to "fuzzy" lines like Maffioli (swiftcord) or Robline. These are dyneema rope usually with a tracer made of something else to fuzz it up. Swiftcord has cordura, Salsa line has Spun polyester, newswift has polypro. They are single braids but the weave of the rope is very different. If your product is similar to one of these, shipped to you by mistake, it will be tough to make a whoopie sling from it.
I found this link, and it appears he is not having the same problem, of course his buries are extremely short.
