Have a Refined Textile Station with a Simple Tailor Augment next to it. When crafting Thread, its yield bonus never applies even though it is specifically listed. The yield does change when crafting Cloth.
Have not tried other refined products except Twine, which also does not have increased yield.
Same here.

Seeing the same -- no bonus yield when making Thread with Excellent Tailor Augment showing active on the station.
