Battery acid in a 1:1 mix with Distilled water is actually 17.5% by weight (or 9.5 by volume), not 25%.
If you're dyeing at under 110 degrees, you are extremely lucky that it is being absorbed at all. Room temperature is not the temperature of any room you happen to be in. Typically it is a range of 65-75, but I wasn't aware that any of Caswell dyes were recommend for use at room temp. In any case, I'm glad you got your problem resolved.
