Powdered fabric dye
From time to time, a dye lot will come in of a base color of Fiber Reactive dye dust (which we use to blend other colors) this is certainly difficult to dissolve and can even keep undissolved dark "freckles" regarding material. Dharma Trading company denies dye it doesn't pass our "solubility test", but colors will surely differ, especially the "mixing" reds like Fuchsia and Light Red, and mixes with red inside. For solid color dyeing, specifically much more pastel colors, this could be specifically irritating. Alternatively, tie-dyers and painters might never notice. It is not a consistent issue, it is one thing every person ought to know how to deal with, and that can occur every so often no matter where you get your dye.
Dharma recommends these dye dissolving treatment:
Constantly add fluid to dust, perhaps not dust to liquid. Smash the dust with a sturdy spoon while incorporating the fluid really gradually. This is certainly called "pasting" the dye. (We recommend this technique also for non-problematic colors, in addition.) If it is a well-dissolved slurry, it could after that be put into the dye bath or even the remaining water can be included in case it is for wrap dye. For difficult to break down colors, usage Urea liquid instead of plain water to paste-up the dye. (break down some Urea in heated water, after that allow it cool to warm) In addition several falls of Calsolene Oil will (breaks area stress). Except for Jet Black, #250, Fiber Reactive dye powders should always be mixed in lukewarm water (like a baby bottle), perhaps not hot or cold. **If you are worried about the "freckle" issue, we suggest further straining it after its mixed and blended with even more water, through something like slim bits of silk(5 or 8mm Habotai is very effective) or fine plastic stockings put in a funnel or strainer. Experienced dyers will tell you it's really worth this bit of time and energy to make sure a freckle no-cost dye task!**
Dyebaths - with difficult to reduce colors, include the pre-dissolved dye to your bath, and combine really, BEFORE incorporating the sodium. Salt lowers solubility, if you do occur to have little particles of undissolved dye, they stay a much better chance of going into option without sodium.
