You will get results without Soda Ash, but Soda Ash makes Procion over 100% percent brighter. That means more than twice as vivid, which is a big deal. The Soda Ash raises the pH of the dye bath and acts as a sort of chemical sandpaper that gives some tooth so that the dye can latch on and hold permanently. HIGHLY recommended.

Lumiere, Neopaque, Airbrush and Jacquard Professional Screen ink all stick very well to leather with nice flexibility and no cracking. Textile works to an extent, but is not as good as the others in terms of adhesion. On absorbent leather, Dye-Na-Flow is really excellent, especially on suede.

Pearl Ex is completely inert, neither water nor oil based. It can be added to paints of all kinds, resins, wax, polymer clay, concrete, glue and just about any other medium you can think of. Pearl Ex itself has no binder, so it only sticks, if you apply it with some kind of “glue” to hold it onto the surface.

In general, the answer is yes. Iron at the appropriate temp for the fabric you painted on. However, Lumiere, Neopaque, and the JSI professional screen inks all self-cure in 72hrs. and a heat set is unnecessary. If Airfix is added to Textile, Airbrush, Dye-Na-Flow or Versatex, it too will set by itself in 72hrs. All paint treated with Airfix should be used within 3 hrs. of mixing.

No, you cannot. Dye colors mix perfectly and transparently. If you dye a blue shirt yellow it will be green. Removing color on natural fabrics is fairly easy with our Color Remover or even bleach (can damage fabric). Color on nylon can be removed, but removing color from polyester is extremely difficult. For natural fabric, pink to red transitions are easy as are blues to green. Black to red or purple to yellow type of transitions must begin by removing the original color. Dyeing darker is always easier than lighter.

If you would like to be able to see the dyes better while working with them, add a colorant that will not stain the fabric you are working on. We recommend PearlEx or iDye Poly. You may also use food coloring, a small amount of paint or dry pigment.

No, you can use the iDye Poly with other types of dyes, but you must adhere to the Poly temperature. You can mix Procion, Acid Dye, or iDye Natural in the same pot for a mix blend garment and dye all threads simultaneously. The poly does not react with the other dyes, so it will dye the poly portion and the natural dye will dye the natural portion. Soda Ash and vinegar do not affect iDye Poly’s performance. You can choose the same color for poly and natural, or you can choose similar or disparate colors of your choice. iDye Poly will dye the poly portions and the natural dye will dye the natural portions.

The water in the washing machine does not reach boiling, so it is not hot enough for iDye Poly. In the machine it will stain any plastic portions of the washer (and can be transferred to polyester clothing at a later date) and while the dye looks like it works, it will rub off on other clothing and wash away next washing.

Procion is a fiber reactive dye that chemically bonds to cotton and can be used in cold water. It is among the most lightfast and washfast of dyes. iDye natural needs heat, 180 degrees for best results. It is a direct dye which is fast and gives very even color, but it is only stuck in the fiber so it is more likely to both fade and wash out. Procion can be used for Ice dyeing and in squeeze bottles for tie dye. iDye natural will turn out very pale in these colder applications.

Dyes are usually very specific to the fabric. Acid dyes (Silk Colors) for protein fibers (silk, wool, nylon), Procion for cotton, and iDye covers all natural (iDye Natural) and synthetics (iDye Poly) pet, nylon, so it is the most widely applicable, but also the Natural iDye is the least permanent of any of these dyes (fastest working shortest lasting).
