iDye Poly - Polyester Textile Dye - Jacquard

Jacquard iDye Poly: finally, dye polyester

Dyeing polyester? For a long time the answer was: impossible, at least without a dye house and special techniques.
Then came iDye Poly from the USA.
With this hot water dye, polyester and nylon can also get a new colour, simply in a cooking pot.
In costume departments, iDye Poly has long been indispensable: for polyester costumes, synthetic wigs, buttons, Worbla and even sneaker soles.
24 strong shades, including three neon colours, Magenta, Berry, Navy, Teal and Aqua.

At a glance

• Hot water textile dye for polyester and nylon in a dissolvable pouch, 14 g
• With one sachet of Color Intensifier (colour booster) in every pack
• 24 shades, intermixable
• Dyes at approx. 95 °C in the pot or in the washing machine
• Also for synthetic wigs, buttons, Worbla and sneaker soles

How much dye do I need?

• In the pot: According to the manufacturer, 1 pack is enough for 1 to 1.3 kg of fabric. For strong colours we recommend 400 to 500 g of fabric per pack.
• In the washing machine: 3 packs for 500 g of fabric, and one more pack for every additional 500 g. For 1.5 kg of fabric that makes 5 packs. With less dye the colour will only turn out weak.
For large quantities there is iDye Poly Pro 450 g.

What can I dye with iDye Poly?

• Polyester and nylon (polyamide): costumes, lining fabrics, yarns, sewing thread
• Synthetic wigs
• Buttons and other plastic parts, including Worbla
• Rubber sneaker soles: iDye Poly is recommended by well-known sneaker artists. For this you also need acetone for pre-treatment.
• Blended fabrics: together with iDye Natural in one bath

Dyeing hot? Don't worry about the care label

The hotter and the longer you dye, the more intense the colour becomes. Leave the fabric in the dye bath for at least half an hour.
Many labels say “wash at max. 30 °C only”. But cotton, linen, polyester and nylon can easily take a boil wash. The cotton of your jeans was bleached and washed hot several times before it became a garment. And cotton is ironed on the hottest setting.
What makes clothes shrink is above all high spin speeds and the tumble dryer, not the hot wash.
Polyester even needs really high temperatures of approx. 95 °C so that the dye can penetrate the fibre.

And the seams stay white? Not with iDye

You know the problem: the garment shines in a new colour, but the seams, the label and the zip have stayed the old colour. The reason: they are usually made of polyester.
The solution: add iDye Natural and iDye Poly together to the same dye bath. This way your garment is dyed through and through, including seams, labels and buttons. Or you combine two different shades and get exciting two-tone effects.

When does it not work?

• Down: Please never dye garments with down filling with iDye Poly. The high temperature makes the down stick together.
• Coated fabrics: Some polyester fabrics are impregnated or treated with UV protection, for example curtains, parasols, garden cushions, jackets and rucksacks. These fabrics hardly take up any dye. Unfortunately you often only notice this after dyeing. So do a test first.
• Too little heat: Weak dyeing in the washing machine is usually due to too little dye or too low a temperature.

Pot or washing machine?

iDye Poly is actually made for dyeing in the pot, but also works in the washing machine. Whenever you can dye the garment in the pot, we recommend the pot: the result is stronger and you need less dye. It is best to use the washing machine only for items that are too big for the pot.
The usual parts of a washing machine made of painted metal, PVC and rubber are not stained by iDye Poly. Still, pour the dissolved dye slowly and carefully into the detergent drawer.

Jacquard iDye Poly - Instructions for use

iDye Poly is an easy-to-use soluble dye powder for fabrics made of 100% polyester and nylon. Dyes up to 1-1.3 kg of dry fabric.
Please use in well-ventilated rooms - iDye Poly is not odourless.
Not all synthetic fibres are made in the same way. The dyeing result depends on the type of fabric, the temperature of the dye bath and the duration of dyeing. Please always test first.
The dye liquor can be safely disposed of in the sewer, the drain or a septic tank.

Which iDye is the right one?

• iDye for Natural Fabrics for 100% natural fibres
• iDye Poly for 100% polyester & nylon
• for blended fabrics of natural and synthetic fibres, combine similar colours from the iDye for Natural Fabrics and iDye Poly colour palette.

For best results:

• Read the complete instructions before you begin.
• For the best results and maximum colour intensity, dye on the stove.
• Keep the items to be dyed in constant motion to obtain an even dyeing result.
Please note: use less dye powder for lighter shades.
Polyester is difficult to dye and needs great heat to achieve a good colour; we therefore recommend dyeing on the stove only for polyester.
Please note: the instructions apply to the most intense dyeing. For lighter shades, dissolve the contents of the sachet in a container of hot water. To get the desired shade, add the right amount of dissolved dye powder to the dye bath. Please note: the longer the items stay in the dye bath, the darker the shade.

Dyeing on the stove, 100% polyester and nylon:

Important: the utensils and pots used for dyeing should not be used for food.
1. Fill a stainless steel or enamel pot with enough water so that the items can move freely in it. Set to high heat (93 ºC).
2. Add the soluble dye powder iDye Poly and the colour booster iDye Color Intensifier to the water and stir until the powder has dissolved.
3. Add the damp garments or fabrics and bring the bath to the boil. Keep the dye bath at a high temperature. Stir constantly for 30 minutes to 1 hour to obtain an even dyeing result.
4. Wash the garment with a mild detergent and let it dry.

Dyeing on the stove, blended fabrics of natural and synthetic fibres:

1. Fill a stainless steel or enamel pot with enough water so that the items can move freely in it. Set to high heat.
2. Choose the iDye Poly colour that comes closest to the iDye for Natural Fabrics colour you are using. Add both sachets to the dye bath. Add the Color Intensifier and stir until the powder has dissolved.
3. Add the damp garments/fabrics and bring the bath to the boil.
4. Add 250 g salt (non-iodised)/dyeing salt for cotton, linen and viscose, or 75 ml white vinegar for silk. Do not pour directly onto the fabric.
5. Let the dye bath simmer gently and stir frequently for 30 minutes to 1 hour. This gives you an even dyeing.
6. Let the fabric cool slowly, wash it with mild detergent and let it dry.

Dyeing in the washing machine

1. Dissolve the iDye Poly dye sachet in hot water and add the colour booster iDye Color Intensifier to it
2. Fill the washing machine with the materials to be dyed and choose the longest and hottest wash programme (95 ºC) without pre-wash.
3. Let the machine run for at least 10 minutes so that the water can heat up.
4. Now pour the dye liquor into the detergent drawer.
5. The clothes should now dye for at least 1 hour.
6. Afterwards wash the garment with a mild detergent and let it dry.

iDye FAQs and troubleshooting

Can I dye viscose with iDye? And what do I do for nylon?
• Yes, iDye Natural is fantastic for dyeing viscose (which is really synthetic cotton). Nylon has to be dyed with iDye Poly.

Is the dye non-toxic?
• When used correctly according to the instructions, dyeing is safe. However, some shades are labelled, for example because of possible skin allergies. You will find the exact information for your shade in the description under “Hazard information” as soon as you select the shade. Always wear gloves when dyeing.

Which containers can I use?
• Do not use a pot that you want to cook in. Stainless steel or enamel pots are best. Aluminium pots are not recommended, but will work in an emergency.

Can I also use a Teflon pot?
• Yes.

What is the soluble powder in the sachet made of?
• It is PVAL (polyvinyl alcohol).

Is the dye bath harmless to septic tanks?
• Yes.

What is the safest and most ecological way to dispose of the dye bath?
• Dispose of the dye bath in accordance with local regulations.

How much fabric can one sachet dye?
• One sachet dyes up to 1.3 kg for dark shades (in the pot). You can also dye larger quantities of fabric with it, but the shade will then get lighter and lighter.

Should I use 2 sachets for darker shades?
• It depends on how much fabric you want to dye and how much water you use. You get darker shades with more heat, less water or more dye.

Will the garments shrink? Why do I have to use hot water?
• Many dyes are a mixture of several colours. Each colour reacts at a different temperature. 82 °C (180 °F) is the optimal dyeing temperature for iDye Natural / iDye Poly requires 95 °C. You therefore need hot water to achieve the best possible colour. If your fabric cannot tolerate high temperatures, use a cold water textile dye such as Jacquard Procion MX.

Do I have to add salt and/or vinegar?
It is not strictly necessary, but highly recommended for maximum colour intensity.
• Salt is for cellulose-based fibres such as cotton, linen, hemp, etc.
• Vinegar is for protein-based fibres such as silk, wool, feathers, etc.
• No salt is needed when dyeing polyester and polyamide.

What are the salt/vinegar for?
• Salt or vinegar drives the dye into the fabric.

Can different colours be mixed?
• Yes.

What do I do if I want a lighter shade?
• Use less dye! Dissolve the dye powder in a pot beforehand and use only what you need. You can keep the rest and use it later. You can also cut open the dye sachet and spoon out a small pinch of dye powder.
• Dyeing at lower temperatures is another way to achieve paler shades.

Should I use iDye Fixative together with iDye Poly?
• No, that is not necessary. The fixative is only used in combination with iDye Natural. It improves wash fastness.

Can I keep the dye bath and use it again later?
• Yes, that is possible, but not recommended. It is very unlikely that you will get the same result with the second dyeing, especially with an iDye colour that consists of a variety of dyes. Each colour in the mixture dyes with a different intensity, so the ratio of the colours remaining in the dye bath changes after the first dyeing. If you still want to dye, and accept possible uneven colouring, remember that you may need to reheat the dye to dissolve the colour again.

How long does the water-dye mixture keep?
• It keeps indefinitely. However, over time the dye powder will settle and the mixture must be heated to dissolve the dye again.

Can I use iDye with an airbrush?
• In principle, yes. However, it is not recommended. Jacquard has a number of products that are better suited for spraying. The Jacquard CVS dyes or Dye-Na-Flow may be suitable for your airbrush work. We are happy to advise you.

How does tie-dye work with iDye Poly on a polyester shirt?
• Use the sublimation method, or apply the dye and steam the shirt at 100 °C. Alternatively, the shirt can be tied and dipped into the boiling dye bath.

Can I paint on fabric with iDye?
• It is possible, but not recommended. Jacquard's fabric paints or a cold water textile dye are better suited for this work.

If I leave the product unopened, how long does it keep?
• It keeps indefinitely.

The colour bleeds. What did I do wrong?
• Maybe you did nothing wrong at all! Some shades, such as the red Crimson, tend to bleed. To avoid this, use the fixative iDye Fixative. The fixative improves the wash fastness of every colour.

My black dyeing turned olive green. What happened?
• Presumably the dye bath was not hot enough. For a black dyeing, the temperature of the dye bath must be at least 82 °C. The dyeing time may also not have been long enough.

Why is the colour on the fabric not the same as on the packet?
• The picture only shows the approximate shade. Different fibres always give slightly different shades. Depending on the fibre, the difference can also be considerable.

After using iDye Poly, a strong chemical smell remained on my garment. How do I get rid of the smell?
• Wash the garment several times in very hot water with a powerful detergent.

What is the best way to get a very light shade on a 100% polyester dress?
• Use only a small portion of the dye powder from the sachet. To do this, you can either dissolve the dye in a container beforehand and use a small amount of it, or cut open the sachet and take out a little powder.

Why does the navy blue iDye for Natural Fibers look purple when mixed with water?
• Our navy blue shade is a very warm, reddish tone. At lower concentration the dyeing turns slightly purple. At high concentration, however, you get a beautiful warm navy blue. The red component in the colour dyes less than the other components. To achieve the warm navy tone, the dye powder must therefore contain more red. Dissolved in water, the colour therefore looks slightly purple.
• Don't forget that the colour of the dye bath will always differ slightly from the result of your dyeing on the fabric/garment.

I used iDye Color Remover on a pair of store-bought jeans. After 40 minutes on the stove, just below boiling and with constant stirring, the colour of the jeans has not changed!
• Not all colours can be removed. iDye Color Remover removes iDye colours from natural fibres very well. On other fabrics the product will not necessarily work. Do a test first!

I no longer need my stainless steel pots for dyeing. If I wash them thoroughly, can I use them for cooking again?
• No, unfortunately that is not possible. Pots and utensils that have been used for dyeing should no longer be used for food.

How do I prevent iDye colours from staining the rubber parts in the washing machine?
• You can either dissolve the dye powder sachet before putting the dye into the washing machine, or run a hot wash programme with bleach several times after dyeing.

Does iDye for Natural Fabrics also work in front-loading washing machines?
• Yes. Watch this video: https://vimeo.com/jacquardproducts/idye

Can I use iDye Poly in the washing machine?
• Yes, iDye Poly also works in the washing machine. The colour is less intense there than on the stove, and you need more dye (see description). Choose the hottest programme (95 °C).

I dyed a cotton garment with iDye for Natural Fabrics, but all the seams stayed white. What happened?
• The seams on store-bought clothing are often made of polyester. Polyester cannot be dyed with iDye for Natural Fabrics. To dye the seams together with the garment, mix the same colours of iDye Natural and iDye Poly in the dye bath and follow the stove method.

I dyed a synthetic garment with iDye Poly and the buttons were dyed too. Why is that?
• iDye Poly dyes everything made of synthetics, including plastic buttons.

Produkt hat überzeugt

Hab in der Maschine gefärbt und die Farbe hat keine Spuren hinterlassen. Ich hätte mir die Farbe an meiner Jacke etwas intensiverer vorgestellt, hatte türkis bestellt und es ist ein schönes hellblau geworden. Die Lieferung war sehr schnell und die Anleitung gut. Ich würde es wieder machen und hier bestellen. Auch meine Befürchtung wegen der hohen Temperatur war unbegründet.

Polyester färben

Super schnelle Lieferung und tolles Produkt. Es hat alles zu meiner Zufriedenheit geklappt.

Perfekt

Ich habe meinen Pullover mit der iDye Poly - Polyester Textilfarbe 457 Crimson gefärbt.
Der Pullover hat die Farbe sehr gut angenommen. Leider ist bei dem Ton die nachfolgende Wäsche rot geworden.
Daraufhin habe ich mich an der Firma gewandt, wo mir auch sofort geholfen wurde.
DANKE DAFÜR 👍
Habe dann 2x die Waschmaschine mit bleiche laufen lassen ( zur Sicherheit ) und danach 1x mit Waschpulver ( benutze sonst nur flüssig Waschmittel ) und es hat geklappt.
Fazit.....einen wunderschönen Pulli und eine Waschmaschine die blitzsauber ist.
Würde immer wieder bei ihnen kaufen. LG.

Tolles Produkt

Ich wollte einen weißen Pullover aus 100% Polyester in schwarz umfärben und musste zu meinem Entsetzen feststellen, dass man Polyester eigentlich gar nicht färben kann.
Durch Zufall stieß ich bei meinen diesbezüglichen Recherchen auf diese Seite und las von ihrem tollen Produkt (iDye Poly) - übrigens das derzeit einzige auf dem deutschen Markt - mit dem es trotzdem gelingen sollte.
Ich las mir die genauen Beschreibungen und guten Rezensionen dazu durch, sah mir das Video an und stellte außerdem per E-Mail noch Fragen, die sehr freundlich und zügig beantwortet wurden.
Daraufhin wurde bestellt und die Lieferung kam wirklich schnell und liebevoll verpackt an, zusammen mit einer genauen Gebrauchsanweisung auf deutsch.
Nun habe ich einen schwarzen Pullover und bin sehr zufrieden. :-)
Es hat wunderbar funktioniert. Ich habe im Kochtopf genau nach Anweisung in der Küche auf dem Herd und bei geöffnetem Fenster gefärbt. Der Geruch war überhaupt nicht extrem und wirklich gut händelbar.
Alles in allem bin ich sehr zufrieden und kann das Produkt *iDye Poly* wie auch die Firma PATIN-A nur empfehlen!

Durchweg positiv

Ich hatte Textilfarbe bestellt. Preislich lag die Farbe weit unter dem Normalpreis, den ich auf anderen Shops für diesen Hersteller gefunden habe. Das Produkt selbst hielt was es versprach. Der Händler war top. Der Versand ging auch sehr schnell. Also alles bestens und nach meiner Erfahrung ohne Einschränkung zu empfehlen.
