Hi pvankeuklom,
While I’m certainly not as knowledgeable about bedding as I am about mattress materials (that’s a specialty in and of itself) there are several members here who are and visit from time to time.
In the meantime though post #7 here will give you some good resources and information about the different types of fibers and fabrics that are generally available and the pros and cons of each. When you are buying bedding and sheets it’s just as important IMO to look at the actual materials in the product and untangle some of the conflicting information as it is with mattresses.
Sometimes"thread count" in sheets can be just as misleading as “coil count” in mattresses because it’s only one piece of a larger puzzle and I think it’s probably just as common to see inaccurate information about bedding as it is with mattresses.
Hope this helps
Phoenix
