Synthrapol is a detergent used in fibers before dyeing them. It is also used to wash out fiber reactive dyes after they've been dyed.

How long do you leave a shirt in the dye to tie dye?
You should wait at least 24 hours. Then you should wash with Synthrapol SP detergent to stop the colors from running.
Do you rinse your tie dye shirt before you wash it?
After you tie-dye a shirt you need to wash out the loose dye that didn't fix to the shirt. Hopefully you used "reactive type" dyes which are permanent on cotton if used correctly. Here is how to wash out the loose dye: 1. Leave the shirt tied up! 2. Let it sit for a while if you have time to. If you let dyed shirts sit for a few hours it is much easier and cleaner to wash out the loose dye. 3. Wear gloves when you touch the dyed shirt because it's messy! 4. When you are ready to wash the loose dye out, take the tied up shirt to your sink. Leave it tied up and put it in the sink and turn on the cold running water. Let the water flow onto the shirt. A lot of loose dye will start to flow out from the shirt in the cold running water, this is normal. The cold flowing water will wash away the dye and keep the colors from running together and keep the white areas white. 5. Leave the shirt tied up and rinse and rinse until you kind of get sick of rinsing! 6. Finish washing out the loose dye by filling your washing machine with warm water. Add laundry soap (or special synthrapol detergent you can buy from the dye seller) and get the water sudsy. Untie the shirt and throw it in the soapy water. If you've rinsed out several shirts you can put them all in the washer together now. Wash the shirts in the washing machine as many times as you need to until when you look in a rinse cycle the water is clear and no more dye is coming out of the fabric. When you get to this point, you're done.
When you make tie dye shirts how do you put different colors on it?
For example, the typical spiral pattern of tie-dye t-shirts starts out with a 100% cotton t-shirt. Soak it in a solution of water and soda ash (available at dye companies such as Dharma Trading Co) fwhile you prepare the rest of your tools and dyes. Supplies: A bucket for soaking the T-shirts soda ash procion dyes in the basic colors-red, blue, yellow, black--others if you want specific color themes a couple of large buckets or tubs for rinsing--or a washing machine synthropol--from the same source as your dyes--a sort of detergent used to remove extra dye from the rinsing RIT dyes will do the job, but not as well and not as long-lived. Mix the dyes according to the directions you receive with them. Procion cold water dyes are the best, as RIT dyes will wash out and fade fairly quickly. Place your dyes in squirt bottles (like clear ketchup/mustard bottles, cylinder-shaped with a narrow tube out the top.) remove the t-shirt form the soak, and wring it out to as barely damp as you can. Moist cotton will absorb the dyes better than dry. lay the t-shirt flat on a table covered with a plastic cover. A split open garbage bag will work. Pinch a bit of the shirt in the center and begin to twist it, keeping it flat, until it's all coiled up in a spiral circular flat shape. Tie a string or place a big rubber band around the outside edge--like around the tread of a tire, not across the spiral folds. Wearing rubber gloves is a good ides during the dying procedure, as you will turn colors--and they won't wash out for a long time! Once it's tight and flat, take your first color bottle and carefully squirt the dye across it in a centered diagonal stripe, not too much. Make stripes across the coil with all your colors and let it sit a few minutes. Oddly, if you squirt the dye in line with the coils, you'll get stripes when you undo the coil. Untie the string, or remove the rubber band and rinse thoroughly in a large bucket or tub of water, then another of clean water until the color is all washed out--ideally, use a washing machine with some Synthrapol in the wash to keep the released dyes from reattaching to your cotton. When all rinsed, dry in a drier, or on the line. Be sure to wash your washing machine out after, doing as load of old towels or other items you don't care about the colors, with a little bleach will clean out any remaining dye.
