How do i achieve black denim to thieve black RIT fluid dye ? i hold tried twice & it's not getting any dark?
Black is rugged for even the most experienced dyer to do with all the right tools. I own been dying fabrics for something like 5 years and I use cold water dyes (not Rit) and still can't get a moral deep black. The problem is typically getting the dye to set into the fabric.
Water must be boiling hot!! Do you have an old canner? put the Rit dye contained by it on the cook top and turn on the heat. Get the pot boiling then put the black denim surrounded by and cook it about 15 minutes at simmer temperature. turn sour heat and let cool. fish out the denim and rinse surrounded by washer with vinegar in the hose.
Denim is not all navy blue or black. basically the weft threads are blue or black or whatever color. The warp threads are white. This makes it knotty to keep the dark colors contained by the fabric. Denim is woven on a 3-harness set up. Plain weave fabrics are woven on a 2-harness set up and fancy things approaching jacquard are 4- to 8-harness.
more info than you asked, but I was just reading how to warp loom to weave denim.
Answers: You will get better results if you use fiber reactive dye, instead of Rit. I recommend Dylon Permanent 12 Black, which you can find in a sewing store such as Joann's; use one packet for every half-pound of textile. If you have four pounds of black denim, then you will call for eight packets of Dylon Permanent dye. You can also do very in good health with Procion MX black mixtures.
In general, it is not difficult to grasp a good black with fiber reactive dye, if you use satisfactory dye. You must use two to four times as much dye when dyeing black as any other color, because it is such a dark color. You cannot dye polyester blends or any fabric that have been treated to be stain-resistant or permanent press. You must follow a pious recipe, using soda ash or another high pH chemical to set the dye. In the case of Dylon Permanent, dye, the high-pH chemical is already included contained by the dye mixture¡ªjust follow the instructions on the back of the dye packet¡ªbut other dyes such as Dylon Cold dye require added soda ash.
Rit dye tends to produce white colors, so it is difficult to get a good black using Rit dye. It also fade quickly in the laundry. You will catch much better results if you use a fiber reactive dye such as Dylon Permanent or Procion MX.
To use Rit dye, you must boil the fabric in the dye, and use several boxes of dye if you want a shade black. Even then, Rit dye is less unwavering than a fiber reactive dye, and must be hand-washed separately in cool water. Rit dye is not a totally good choice for dyeing cotton because it fades so at the double.
