Then there is this from Physics for Cavers: "Tests conducted in a study by Smith (1988) indicate that treatment with concentrated fabric softener reduced the strength of a new rope. Frank (1989) showed that certain ropes treated with diluted softener (per manufacturer’s recommendations) were stronger than the same rope without softening, after aging and washing. Frank reported that the likely mechanism at work explaining these results is that the fiber lubricants contained in new rope are lost with age, allowing the fibers to cut one another. Fabric softener replaces some of the lubricants. Excess softening leaves the rope effectively wet, with the corresponding loss in strength."
