Do i assume by this chart that even tho my dye solution volume is increasing due to a higher DOS, that this isn't necessarily true for the soda ash and salt. From this chart, I assume, I cap out at 4% and that any DOS higher than 4% my needs for soda ash and salt would remain the same as 4%, no more?

So for DOS of 5.1, 6.0, 8.0%  all used 90g/L of salt and 15 g/L of soda ash.  Is that what you were asking?

Exactly what i was asking - why don't the soda ash and salt increase as they do with the under 5's?

What does salt in the process? i can't remember.

I started with the pure for chenille today - any ideas for successfully dyeing solids? when it dries i'll post pictures -it's been the biggest PItheA to date -

These dyes are very soluble in water and might stay  dancing around in the water forever; adding the salt reduces their solubility and forces them towards the fiber where they can bind.  90g/l in the maximum effect, adding more won't do anything. 

I used to used 100L dye bath, that was 9000g of salt.  Do you know how big a pile of salt that is???  And then it all goes down the drain.

Is this rayon chenille?  What did it do besides shrink up and get hard?  Those effects will go away when it is dry.

Yep, rayon - shrinky dink for sure - i'm afraid it's not too even - but will tell for sure when i chip them. Initially i wasn't going to do the chenille, because in my history with chenille, i have never successfully dyed solids - it would be huge if i could get it down. just wondered if you follow any other process other than the one we are doing for the other fibers.

If the skeins you dyed are not level, let's go back to Boring Beige and tweek the process for chenille.  Does it need more water, more agitation. Adding he salt in portions can help too.  But one step at a time.

First is it level or not?
