I learned tonight that, if I pack things efficiently, I can do a full dye batch and one undyed batch of rope in 7.5 hours. Seems pretty good and likely not reducible given the amount of time various steps take, like vat soaking.
I also tested processing the undyed batch in the washer rather than the pressure cooker. One wash ws about 50% as effective in softening the final batch so it is good for concurrent processing but will likely require at least two cycles to get the same sort of softness in the final rope. Cost/energy use is probably a wash.
Note that I had an equivalent length of rope in the cooker that I dryer with the machine washed batch to control some of the variables. Which is how I'm roughly determining the dial softness difference.
I now have an additional 3x30ft lengths of fuchsia and 3x15ft and 1x50ft lengths of natural rope. With tassels!
