Using RIT dye in the wash, do you need salt or vinegar, or a fixative after?

I am planning to dye 7 1/2 yards of 100% cotton twill in the washer. Do I need any bonding agents during or after the wash?


Also, if the color is not deep enough, can I dye again? (The store is about an hour away, and we're on a schedule, so it would be great to go ahead and see if what we have will work first.)Using RIT dye in the wash, do you need salt or vinegar, or a fixative after?
You always set colors in clothing with a bit of vinegar in your wash. This is from a child of the seventies--love that tiedyed-- and a manager of a Fabric Store.Using RIT dye in the wash, do you need salt or vinegar, or a fixative after?
Read the directions. I believe RIT asks for some salt, but that's been awhile since I've used it. Best to follow the directions!!





If the colour is not deep enough, yes, you can dye over it. Dry a piece of it to see the true colour, since it looks dark when wet. Be sure you read the directions, and use the right amount of dye for the amount of material you have. That will ensure good results.
Yes you can over dye (dye again).





Rit says for best results to add salt to the dye bath:


Always follow manufacturer's care instructions for your fabric as well as RIT Dye package or bottle instructions.


Remove stains on fabric with RIT Super Stain Remover or RIT Color Remover before dyeing to achieve uniform color results.


Choose your colors. You can use one, two, three or as many colors as you like on one garment. However, if you use more than one color, it's usually best to start with the lightest color.


Be sure to use enough dye for the weight or size of the project. For example, for a pound of dry fabric (about 3 yards), use one package of RIT powder or 1/2 bottle of RIT liquid in


3 gallons of water.


Dissolve powder dye thoroughly in 2 cups of very hot water first to avoid dye spotting. Stir dissolved powder dye or well-shaken liquid dye into dye bath until evenly dispersed. Never pour liquid or powder dye directly on fabric.


For the deepest color, use a water temperature of 140潞F/60潞C.


When dyeing 1 pound of dry fabric of dark or bright colors such as Black, Dark Brown, Cocoa Brown, Navy, Purple, Aubergine, Wine, and Dark Green, use double the amount, or 2 packages of RIT powder or 1 bottle of RIT liquid, in 3 gallons of water.


For best color results when dyeing fabrics containing cotton, rayon, ramie, or linen, add 1 cup salt.


The longer the garment is immersed in the dye bath, the deeper the resulting color. Items can remain in the dye bath up to 1 hour as long as the water remains hot. You'll also have to make sure the item receives constant agitation or stirring.


Garments will take dye differently due to their fabric content and weight. For example, we've shown below the varying shades of tangerine when used on different types of fabrics.
