I don't know if this reduces the absorbancy, but they look nice. I had saved up a small load in the 1986, 140, extended, sensitive Cottons cycle with Persil, STPP, and oxywhatever. I had to tumble then with heat for a few minutes to get them ready to iron, especially the heavier linen ones. I was looking at some of the ones with tiny holes developing and realized they were bought in the early 70s; how time flies but you don't notice these things except when you are ironing and the cloth is spread out and you watch it go from wet and wrinkled to dry and smooth and hot.
