Hi want2sleep (and kll4),
For some reason I missed your question so I apologize for not replying earlier.
Any latex (Dunlop or Talalay made from synthetic or natural rubber or a blend of both) would be equally 100% latex. Latex is just a rubber particle suspended in water and can be either natural or synthetic. This of course would be different from 100% natural latex which means that there is only natural rubber used in the formulation and that it doesn’t contain any synthetic rubber in the mix. The only way to know the type and blend of any latex layers you are purchasing would be by asking your supplier for the type and blend of the latex because you can’t tell the blend of latex based on how it looks. If they are a knowledgeable, reliable, and reputable supplier (such as Sleep On Latex) then they will provide you with accurate information about the latex they sell.
There is more about the different types and blends of latex in post #6 here.
While it’s not a material that I’m particularly knowledgeable about … you can see some comments about Alpaca in post #2 here and the other sources of information it links to. How it specifically compares to wool would depend to some degree on the fineness of the Alpaca fiber and the fineness of the breed of wool you are comparing it to but it’s generally softer and finer than most wool breeds and is certainly a high quality material although it’s also more costly than wool. It would be suitable for any of the applications you mentioned.
