What does the term “percale” mean?
Though many people assume that “percale” means a polyester-cotton blend, this is untrue. A percale can be made of 100% cotton, 100% polyester, or any combination in between. Percale fabric begins its life as two sets of undid, interwoven threads, known as a “greycloth” that will later have its color and pattern “sprayed” on. The “thread count” of a percale fabric is found by counting the threads going in both directions inside one square inch of the fabric.
