I googled ‘frankenfabrics’, not sure this is a matter of being ‘eco-friendly’.
It’s the general degradation we see in everything. The recycled paper products were just examples in addition to the plague of weirdo fabrics.
I have 100% cotton rag rugs [made in India] that I have used and washed for 20+ years. Real cotton, tight weave, just a couple bucks when I bought them. Still perfectly fine even after many washes.
Today? The ‘same’ rugs are made out of weird fabrics that appear to be from all the unsold or discarded junk clothing. Wash on gentle and they don’t get clean. Wash on a regular cycle and they self-destruct.
