Wow!! Thank goodness for Snythrapol & Retayne!! I was pre washing some brown & copper batiks to prep for a quilt and the water was a bright orange color!! - the most bleeding that I have encountered in a long time and these were good quality batiks! I am so glad that I decided to treat them before using or I would have had a big dye mess later!!
Used Synthrapol in the first bath and then after rinsing used Retayne - maybe this is over kill but I don't want any 'accidents' later!! They finally rinsed clear - I even cut up a color catcher sheet and put pieces in the final rinses to be sure!
I don't trust the color fastness of any batiks or even regular fabric and I will not take a chance of a project being ruined after all the hard work put into it so I use the chemical setters alot! I find I go through so many of the little bottles - the LQS just sells 4 oz bottles and I am constantly emptying them and running to buy more! I asked at the LQS but they don't have a supplier for larger bottles so I guess I have to find it online.
Has anyone dealt with an online supplier for larger bottles of Retayne & Synthrapol? Info/references appreciated

Thanks!!
