Rit DyeMore Synthetic Fiber Dye Product Guide

With Rit DyeMore Synthetic Fiber Dye you can now dye polyester, nylon, acrylic, rayon, and poly/cotton blends. It comes in a variety of colors that you can mix to get an infinite amount of colors.

The All-Purpose Rit Dye also works on rayon and nylon, along with cotton, linen, silk, and wool. Read our article on fabric dye for more information about the dyes we carry. Browse all Rit dyes here.

Fabrics with different fiber contents will not dye the same. We tried dyeing 23 different samples of fabric to see how each takes the dye, including polyester, polyester blends, nylon, acrylic, rayon, and vinyl.

See the video and written instructions below, and don’t miss our detailed assessment of how each type of fabric dyed at the end of this article.

How to Use Rit DyeMore Synthetic Dye

Dry clean only and fabrics that can’t withstand heat shouldn’t be dyed, but if you want to try, test out a small piece first. Some non-fabric plastic items may be able to be dyed, like buttons, beads, and legos. For heat sensitive items, turn the stove off before or a couple minutes after adding the plastic object to the dye bath and keep an eye out if it starts to melt.

Synthetic fibers need lots of heat when dyed, so the stovetop method is the best.

Pre-wash the fabric to remove any finishes with warm, soapy water so the dye will absorb better.

Wear gloves whenever handling the dye and cover any surfaces that need protection before starting.

Fill a pot with enough water so the material can move freely. Heat the water until it’s simmering or almost boiling.

Shake the dye well and add it to the water.

One bottle will dye up to 2 pounds of dry fabric. To get dark or saturated colors, double the amount of dye, especially with polyester. This is a small amount of fabric (twenty-three 4″ x 4″ samples of fabric), but we’re using a full bottle to get a saturated color.

Add a squirt of dishwashing soap and stir well. This helps the fabric to dye evenly.

You can test out the color by dipping a piece of paper towel in the dye bath. Add more dye or more water if needed.

Put the fabric in the dye bath. The material should already be wet.

Stir continuously for about 30 minutes with the water on a low simmer, about 180° F. Make sure the dye is getting to all parts of the fabric so it won’t be splotchy. Polyester should remain in the dye bath for at least 30 minutes, but other materials may come out sooner. Some nylon fabrics dye very quickly and darkly.

Some polyester could need closer to an hour. It’s a little tricky because the polyester may look dark enough when taken out of the dye but might not retain the color when rinsed. If this happens, the fabric can be dyed again for a longer period of time.

When your fabric reaches your desired color or after at least 30 minutes for polyester fabric, remove from the dye bath. Keep in mind, fabric looks darker when wet.

Rinse in a stainless steel sink with warm water, then cooler water, until it runs clear. Wash in warm, soapy water, rinse, and air dry.

The Results

The fabrics ended up dyeing a range of colors from lilac to almost black. These differences are mainly due to the different fiber contents. Here are our observations.

100% Polyester

The gabardine dyed nicely to a light to medium purple, as did the chiffon.

The mirror organza dyed lighter, but it’s also the most sheer of the polyester fabric. The surface remained highly reflective and shiny.

The satin, also a medium purple, retained its beautiful shine.

The velvet dyed the darkest of the 100% polyester fabric. The pile remained soft with a nice luster.

The Minky dyed a medium purple and also kept its soft feel. This Minky has a raised dot pattern that started to disappear due to the high temperatures.

The fleece and felt dyed a light purple. If we had left them in the dye past 30 minutes, they may have retained the color better. Before they were rinsed, they appeared more of a medium purple, but some of the color washed out because it takes longer for these fabric to fully absorb the color. They were the thickest fabrics.

Polyester Blends

This particular broadcloth is 80% poly and 20% cotton. Notice how it dyed lighter than the poplin, which is 65% polyester and 35% cotton. The higher the polyester percentage in poly/cotton blends, the lighter it will dye. The broadcloth and poplin dyed evenly, but not completely solidly. There are slight variations in the fibers.

The polyester spandex is 84% polyester and 16% spandex. It dyed a medium color.

This faux fur is 70% acrylic and 30% polyester. It dyed a saturated medium purple, but in a slightly warmer tone. The fur is dry clean only, so it did shrink and become a little misshapen in the hot water. It also lost some of its softness. Other faux furs will likely dye differently.

100% Nylon

On the glitz sequin fabric, the sequins dyed a lighter purple, while the backing became darker. It took a while for the sequins to dye even though they’re nylon.

The ripstop dyed a dark purple, but the edges curled tightly when hot, so it didn’t dye evenly. The water repellent coating on the back of the ripstop dyed lighter.

The crystal organza dyed a more muted purple and seemed to lose some of its sparkle.

Nylon Blends

The power mesh is 90% nylon and 10% spandex, but unlike the stretch lace, it dyed a nice medium purple.

The dye created an interesting effect on the silver tissue lame. It’s 51% metallic and 49% nylon. The metallic fiber dyed a light purple, while the nylon fibers became a dark purple, giving it a striated look.

The stretch lace is 95% nylon and 5% spandex. It dyed very quickly and became a dark plum purple. If taken out sooner, it may have been lighter and brighter.

100% Acrylic

The Sunbrella canvas outdoor fabric dyed a medium purple that’s quite a bit warmer in color and more saturated than the rest. The faux fur has a lot of acrylic in it and similarly dyed a warm, saturated purple, though darker than the Sunbrella.

100% Rayon

The color of the rayon challis fabric turned out to be a dark purple that’s slightly bluer than others.

100% Polyvinyl Chloride (Vinyl)

We threw in a few vinyls not knowing if they would dye or not because vinyl isn’t listed in the materials Rit DyeMore will dye.

The upholstery vinyl dyed a beautiful dark purple while retaining its gloss.

The oilcloth turned an extremely dark purple that’s almost black.

The clear vinyl appears black, but if held up to the light, you can still see the purple. With both the oilcloth and clear vinyl, if left in the dye a short amount of time, the color may have turned out lighter.

When stored with some other clear vinyl, the dyed sample started to transfer the purple color to the undyed vinyl so be aware that color transfer could happen with vinyl materials.

Of course there are many other fabrics that Rit DyeMore will work on, but we hope this sampling is helpful. As with other dyes, it’s hard to know exactly how the color will turn out because there’s many variables like amount of dye, time in the dye bath, the temperature, and the type of material. Even the fabrics that had the same type of synthetic fibers dyed very differently. We suggest testing small pieces of fabric, if possible, to figure out what combination of variables will produce the results you want.

What is the best dye for bras?
A shopper on Nov 17, 2018
BEST ANSWER: Bras are usually made out of synthetic materials so the Rit DyeMore would work best in most cases.
I have a garment that is 100% polyester and already a medium red with a slight orange cast. I would like to make it a dark burgundy. Would you recommend creating a burgundy color in the Rit dye or go more towards a brownish black?
A shopper on Mar 29, 2018
BEST ANSWER: I'd say start with the burgundy color. If it doesn't seem to be doing what you want, you can always add more black and brown. Or you can re-dye it after it dries. Dyeing is an experiment every time!
Will it work on 100% wool?
A shopper on Jan 25, 2019
BEST ANSWER: Rit All-Purpose Fabric Dye is recommended for wool. We dyed a sample of 100% wool with it in this guide: www.onlinefabricstore.net/makersmill/rit-all-purpose-fabric-dye/
I want to keep same color on my SV boat sail covers. They are large areas. Is it possible being they are sunbrella material?. Suggestions please?
A shopper on Feb 16, 2019
BEST ANSWER: We dyed Sunbrella fabric successfully, however I can't speak to if dyeing it in very hot water damaged the water repellency of the fabric. The high heat is necessary in the dyeing process. It would also be difficult to evenly dye large pieces of fabric.
I have curtains that are currently light yellow, brown and cream-they are a poly/rayon blend. I would like to dye the grey. They are dry clean only. Is this possible? Thanks!
A shopper on Oct 16, 2018
BEST ANSWER: Unfortunately, the gray dye will not cover the pattern, especially dark colors like brown. Since hot water is required, we wouldn't recommend dyeing dry clean only items.
Can you use synthetic dye on canvas shoes??
A shopper on Sep 26, 2018
BEST ANSWER: Yes and the all-purpose Rit dye would also work.
I have a baby blue 50/50 cotton/poly heavy duty sweatshirt that I'd like to dye navy blue. Will Rit All Purpose Dye do the trick or do you recommend (strongly?) using Rit Dyemore Synthetic Fiber Dye?
A shopper on Oct 10, 2017
BEST ANSWER: The poly/cotton would dye somewhat with the All Purpose Rit Dye, but you wouldn't be able to get a dark color like navy. So for your situation, we definitely recommend the Rit DyeMore Synthetic Fiber Dye.
Can this be used on viscose?
A shopper on Sep 4, 2017
BEST ANSWER: Yes, viscose is a rayon fabric. The All-Purpose Rit Dye also works on viscose.
Can I use DyeMore on 100% cotton? It is a white Terry robe.
A shopper on Jul 6, 2019
BEST ANSWER: Yes, it will work on 100% cotton.
Can I dye a black polyester dress to make it navy?
A shopper on Jun 5, 2019
BEST ANSWER: Unfortunately no. Fabric can only be made darker by dye, not lighter. However, if it's not an extremely dark black, you may be able to tint it enough to get a very dark navy.
I have a pure white faux fur. If I put a small amount of dye in the mixture, do I get an off-white colour on my faux fur?
A shopper on Jun 1, 2019
BEST ANSWER: That's right. We suggest using a small amount of the sandstone color. It's hard to say how much because different fabrics absorb the dye at different rates so start with a little and add more until you get the color you want.

Hi I want to dye some net baby pink , Iv tried Dylon in washing machine , it did not work , will your product work please ?

A shopper on Mar 16, 2019

I have a dress that is “gunmetal grey” (70% rayon, 19% polyester, and 11% nylon) and I would like to dye it navy blue. Possible?
A shopper on Feb 17, 2019
BEST ANSWER: Possibly, but it will probably be a more muted navy because of the existing gray color, especially if it's a dark gray.
I have an old wedding dress from 2004 that is 100% polyester it is off-white I need a bright pink color should I buy a darker pink since it seems to come out lighter on polyester?
A shopper on Oct 26, 2018
BEST ANSWER: There's only one color of pink available so the darkness of the pink depends on how much dye you use along with kind of material it is. For polyester, yes, use more dye and keep it in the dye bath for a longer time.
100% polyester?
A shopper on Jul 26, 2018
BEST ANSWER: DyeMore will work on 100% polyester.
I have a dress that’s a grey metallic material and it’s faded, can I dye this another color?
A shopper on Jun 21, 2018
BEST ANSWER: It's hard to say how this specific fabric will dye. Do you know what the content is other then metallic? The metallic lame we tried did dye to a certain extent though not as dark as the nylon percentage of the fabric.

You would probably be able to dye the dress, but the color may be a little muted since it's starting out gray. The other thing to take into consideration is how the fabric will react to very hot water. Though synthetic materials don't generally shrink like natural fibers, it's possible the heat could damage the fabric.

So basically, if you're not going to wear the dress in its current state, you might as well go for it, but there is a risk that it won't turn out well!
I have a 100% polyester dress thats cranberry in color can it be dyed a true red?
A shopper on Jun 10, 2018
BEST ANSWER: The existing color would have to be removed or reduced first. Rit makes a color remover, but unfortunately it only works on natural fibers. So cranberry to true red would not work.
can the stainless pot be used for cooking food safely after dying fabric in it?
A shopper on Nov 1, 2019
BEST ANSWER: Yes! Just wash it clean after with soap, water, and a little bit of bleach.
I have a true yellow 65poly 35 rayon garment I'm trying to get goldenrod, and I currently have the all purpose tangerine. Do you think it will tint my yellow enough for a goldenrod color since it isnt completely poly?
A shopper on Oct 27, 2019
BEST ANSWER: It is definitely worth the shot, just don't make the dye bath really saturated to begin with.
Why can’t you dye dry clean only rayon?
A shopper on Oct 18, 2019
BEST ANSWER: It will shrink.
Will this work on 95% cotton, 5% spandex?
A shopper on Oct 16, 2019

BEST ANSWER: Yes, although the Rit All-Purpose Dye may be the better choice for paper coffee filters.

I have burgundy colored uniforms for my nursing job, we changed to navy blue, can I dye the burgundy uniforms to navy blue?
A shopper on Sep 4, 2019
BEST ANSWER: Unfortunately not if they are made from synthetic fibers. If they're cotton, Rit Color Remover would remove the burgundy, then you could dye navy, but it doesn't work on polyester.
