Not all synthetic fibers are created equal. Results may vary depending on type of fabric, temperature of dye bath and dura- tion. Always test first.
Dye bath is safe to pour down drain/septic systems.

Which iDye?

• for 100% natural fabrics use iDye for Natural Fabrics
• for 100% polyester & nylon use iDye Poly
• for fabric blends that contain both natural and synthetic fibers, combine similar colors of iDye for Natural Fabrics and iDye Poly* 


For best results:

• Read entire instructions before starting.
• For best results, and maximum color intensity, use stove top method.
• Use constant agitation for uniform color.

NOTE: for lighter shades, use less dye.
Polyester is difficult to dye and requires high heat to achieve good color; therefore, we only recommend dyeing polyester with the stove top method.

NOTE: Instructions are for achieving the most vibrant color. For lighter shades, dissolve dye packet in small container with hot water. Add the appropriate amount of dissolved dye to the dye bath to achieve the desired shade. Keep in mind that color will deepen the longer the fabric is in the dye bath.

Stove top method for 100% polyester and nylon:

Note: utensils and pot used for dyeing should not be used for food.
1. Fill a stainless steel or enamel pot with just enough water for the fabric to move freely. Turn heat on high.
2. Add the iDye Poly soluble dye packet and iDye Color Intensifier to water and stir until dissolved.
3. Add pre-wetted garments or fabric and bring to a rolling boil. Maintain temperature and stir frequently for 
1⁄2 to 1 hour. For uniform color, use constant agitation.
4. Wash the garment with a mild detergent and dry.

Stove top method for fabric blends that contain both natural and synthetic fibers:

1. Fill a stainless steel or enamel pot with just enough water for the fabric to move freely. Turn on to high heat.
2. Choose the iDye Poly color closest to the iDye for Natural Fabrics color you are using and add both packets to dye bath. Add Color Intensifier and stir until dissolved.
3. Add pre-wetted garments/fabric and bring to a boil.
4. Add 1 cup/270 g of non-iodized salt for cotton, linen and rayon or 1/3 cup/78 ml. of white vinegar for silk. 
Avoid pouring directly onto fabric.
5. Maintain a rolling boil and stir frequently for 1⁄2 to 1 hour. For uniform color, use constant agitation.
6. Gradually cool the fabric, wash with a mild detergent and dry. 


Dyeing in the washing machine

1. Dissolve the iDye Poly dye sachet in hot water and add iDye Color Intensifier.
2. Load the washing machine with the items to be dyed and set on the longest and hottest washing programme (95°C) without pre wash.
3. Run the machine for at least 10 minutes so that the water can heat up.
4. Now pour the dye liquor in the washing powder compartment.
5. The garments should now dye for at least 1 hour.
6. Finally wash the garments with a mild detergent and leave to dry.

iDye FAQs and Troubleshooting

Can I dye rayon with iDye? How about nylon?
Yes, iDye Natural works great for dyeing rayon (which is essentially synthetic cotton). Nylon must be dyed using iDye Poly.

Is it non toxic?
If used according to the instructions, iDye is safe.

What kind of pots can I use?
Do not use a pot you intend to cook with in the future. Stainless steel or enameled pots work best. Aluminum pots are not recommended, but will work in a pinch.

Will a Teflon pot work?
Yes.

What is the dissolvable packet made of?
PVA (Poly Vinyl Alcohol).

Is the dye bath safe for septic tanks?
Yes.

What is the safest and greenest way to dispose of it?
Dispose according to local and state regulations.

How much fabric will a packet dye?
Up to 3 lbs for deep shades. Much more can be dyed, but the depth of shade will begin to decrease.

For darker colors should I get 2 packets?
It depends on how much fabric you are dyeing and how much water you are using. Darker colors are achieved by using more heat, using less water or using more dye.

I’m worried about shrinkage. Do I have to use hot water? Why?
Yes. Many of the dyes are blends of many colors. Each color strikes at different temperatures with 180°F being optimal. So, to achieve the best and most accurate color possible, hot water is needed. If your fabric cannot withstand high tem- peratures, consider using a cold-water dye like DEKA aktuell or Procion MX.

Do I need to add salt and/or vinegar?
It is not absolutely necessary, but highly recommended for maximum color intensity.
• Salt for cellulose based fibers (cotton, line, hemp, etc.)
• Vinegar for proteins based fiber (silk, wool, feathers, etc.) 


What is the salt/vinegar for?
To drive the dye into the fabric. 


Can the colors be mixed together?
Yes

What if I want a lighter shade?
Use less dye! Dissolve the dye in a jar and use just what you need. The rest you can save and use next time. You can also cut open the dye packet and pour out just a pinch of powder. Dyeing at lower temperatures is another way to achieve paler colors.

Do I use the iDye Fixative with the iDye Poly?
No. The fixative is only used with iDye Natural. It ensures better washfastness.

Can I save the dye bath and reuse it later?
Yes, but it is not recommended. It is unlikely that the second dyeing will produce the same color as the first, especially when using an iDye color that is composed of multiple dyes. This is because each color in the blend strikes at a different rate, which means the ratio of colors left over in the dye bath will change after the first dyeing. If consistent color isn’t a concern, just remember that you may have to reheat the dye to get the dye back into solution.

After it is mixed in the water, how long will it last?
Indefinitely. However, over time, the dye fill fall out of solution. To re-dissolve the dye will require heat.

Can I airbrush with iDye?
Theoretically, yes, but it is not recommended. Jacquard offers a number of products that are more suited for spraying. Consider using Jacquard CVS dyes or Dye-Na-Flow for airbrushing applications. Contact us so we can make a recommendation.

How do I tie dye a polyester shirt using iDye Poly?
Use the sublimation method or apply dye and then steam at > 212°F. Alternatively, the fabric can be tied and then sub- merged in the boiling dye bath.

How can I paint on fabric using iDye?
It is possible, but not recommended. Consider using Jacquard’s fabric paints or a cold water dye for this application.

If left unopened, how long will it last?
Indefinitely.

The color is bleeding. What did I do wrong?
Maybe nothing! Some colors, like crimson, tend to bleed. To stop this, use the iDye Fixative. The fixative works great to increase the washfastness of any color.

My black came out olive green. What happened?
The dye bath was not hot enough. When using black, it is important to achieve at least 180°F. Sometimes, it may also require a longer dye time.

Why did the fabric not turn out the same as the picture on the packet?
The picture is only an approximation. All fibers will yield slightly different colors. Sometime different fibers can yield dra- matically different colors, too!

I recently used some iDye Poly dye on a clothing item and there is a strong chemi- cal smell left on the fabric. Is there anything that I can do to remove the smell from the fabric?
Wash in HOT water several times with a strong detergent.

What would be the best way for me to achieve a very light shade on a 100% polyester dress?
Use just a portion of the dye in the packet. You can either pre-dissolve the dye in a jar and pour off a small amount, or cut open the packet and carefully scoop out a small amount of powder.

Why does the navy blue iDye for Natural Fibers look like purple when mixed in the water?
Our Navy is a very warm/red navy. At lower concentrations, it will dye a purplish color. However, at high concentration, it’s a beautiful warm navy blue. The red component has a lower strike rate than the other components. So it has to have more red to get the warm tones of navy. This makes it look purple in solution. Remember that the color of a dye bath (the color of dye in solution) will always be slightly different than the color it produces on fabric.

I just used the iDye Color Remover on a pair of store-bought jeans. After 40 minutes on the stove (just below boiling and CONSTANT stirring) they are the same color!
Not all dyes are dischargeable. The Color Remover is effective at removing iDye colors from natural fabrics, but it is not guaranteed to work on other dyes. Test first!

I have just finished using stainless steel pots to stovetop dye some fabric. If they are washed thoroughly, can I use them to cook with again?

No. Pots or utensils used for dyeing should NOT be used for food. 

What do you suggest for ensuring that iDye colors do not leach into washing machine interior plastic hulls?
Either pre-dissolve the packets before adding the dye to the washing machine, or run several washes after the dye job, using HOT water and bleach. 

Will iDye for Natural Fabrics work in a front loading washing machine?
Yes, you can watch a video on how to do it here: https://vimeo.com/jacquardproducts/idye

Can I use iDye Poly in the washing machine?
No, iDye Poly requires very high temperatures. It should only be used on the stovetop.

I dyed a cotton garment using iDye for Natural Fabrics but all the threads remained white. What happened?
The threads used to stitch commercial garments are often made of polyester, which will be untouched by iDye for Natural Fabrics. To color the threads at the same time as the garment, mix the same colors iDye Natural and iDye Poly in the dye bath and use the stovetop method.

I dyed a synthetic garment with iDye Poly and even the buttons took the color. What happened?

iDye Poly will color just about anything synthetic, including plastic buttons.
