The “traditional” resist (what prevents indigo color to stay on fabric so you get white pattern) material called papp that is used in the region is a mix of gummy arabicum and copper sulfate and some other things ( that are usually the secret recipe that you can not know). As copper sulfate is poisoness when you wash it out directly to the draining system, and Zeugf\u00e4berei does not have special draining system to separate the poisoness waste water, Janina came up with papp that does not contain copper sulfate. <\/p>\n\n\n\n

She made many research and experiments. Inspired by Bousen-Nori from Katazome technique in Japan<\/a>, she uses Rice flour and Rice bran as a base. The Japanese recipes are basically just this two with water… but she went on to make more fine adjustment to suit to the k\u00fcpe here. She adds also coconut oil, tapioka powder, gummi arabicum, eisen sulfate (this is not poisoness in small quantity) and kalk. <\/p>\n\n\n\n

Rice bran (called Nuka) is a typical material in Japan as rice farming is very common and it is a by-product that are almost waste. Japanese use it to pickle vegetables, to wash pans, to soften bamboo shoots…<\/p>\n\n\n\n

But in Europe, it is not a common material and it is not easy to obtain. Janina also tried other types of bran, like wheat bran, oat bran… but it does not work the same way. Then she found out that rice bran are sold in Europe as horse food! so now they buy this horse food bran, grained it extra fine, let it go through a strainer to get the perfect Nuka powder.<\/p>\n\n\n\n

The papp\/resist needs to match with the k\u00fcpe you are using. This recipe may not work for other types of k\u00fcpe. Janina said, when she was experimenting, she had an idea to add eisen sulfate in the papp as the k\u00fcpe also contains it. This improved the resistance of the papp in the k\u00fcpe much better (meaning it kept the fabric white where you applied). But if you have other mixture in your k\u00fcpe it may not work the same way.<\/p>\n\n\n\n

It looks like the recipe of the Papp\/Resist travels and develops as the time goes. The Japanese got their recipe from Chine around 8th century, which originally was a mix of soy powder and kalk. The advantage of this mix is that it does not come out so easily and keep the pattern very white. But overtime in Japan it changed to rice bran and rice flour resist. They do not know exactly when and why the change happened… but one thing I can say from experimenting is that the mix of soy powder and kalk does not come out easily after dying when you want to wash them out. So, maybe it was a practicality. In China, they still use soy + Kalk as resist for indigo dye print process<\/a> and they scrape the resist off after it is washed and dried. There are also technique to use wax as resist, called Batik and is still practiced widely<\/a> in regions<\/a> of Asia.<\/p>\n\n\n\n

The Rice Bran (Reiskleie) sold here is not very fine. We use spice grinder to grind down to finer powder. We usually grind 5-6 times of 1.5minute cycle to make fine powder out of hourse food Reiskleie. The finer the powder is, the better for printing.<\/p>\n\n\n\n
