We have a bigger selection than ever before! Go back in history, dye something the way they did back in the day. Natural Dyes are usually used with a mordant
to make them "stick" to the fabric (check out the related products at
the bottom of the page), and generally give more muted tones on plant
fibers like cotton and rayon, but are brilliant on wools and silks.
Don't assume that they are better for the environment - it depends -
read about it first. Here is an article we wrote comparing Natural with Synthetic dyes.
**We are now buying our Cochineal (the little dried bugs) directly
from a 5 family farming co-op in Peru who grows the Nopal cacti and
harvests the little critters, so it is fresher, stronger, and less
expensive than ever before! Organic too, as they use absolutely no
chemicals.
This book by Jenny Dean, Wild Color: Revised and Updated
(#BWCRU), will provide you with all the basic info you need to get
started using natural dyes. It's one of the very best on the subject.
Have a look!
How To Use Natural Dyes
Used a simple recipe to get these great colors with our natural dyes so you can have a reference for the colors they will give.
Keep
in mind there are many recipes and mordants that will yield a wide
range of colors and shades from each dye material, so consult a natural
dye book for more on this. We carry Wild Color: Revised and Updated Edition.
Indigo is in a class by itself, so a different recipe is used, also available on our website.
For the deepest colors, use a ratio of 1 to 1 dyestuff to fabric, or 2
oz dye to 2 oz fabric, but you can still get good colors using much
less dye. We used about 3-4 tablespoons per yard of fabric. Cochineal is
an exception as it is very concentrated, so use only about a 20% ratio.
The dyebaths can be re-used to get lighter shades. Experimentation is
the best way to determine the right amount of dye for the type of fabric
you are using and the color. We found the silk
and velvet absorbed the colors the deepest. Some cottons will yield
different and deeper shades using Tara Powder (a form of tannic acid) as
a mordant with soda ash as an assist.
Yellows can be overdyed with indigo to get shades of green, and reds overdyed with indigo will give purples.
The Method:
- Prewash your fabric with synthrapol, rinse well.
- To mordant the fabric (or fiber or yarn) simmer together with 1.75 tsp Alum
and 1 tsp Cream of Tartar per pound of fabric for 1 hour. Allow
the fabric to cool in the solution. Squeeze out excess water from
material. Rinse and discard solution. (all the alum will be absorbed by
the fabric)You can allow the fabric to dry if you want to stockpile some
pre-mordanted material, but you want to use it in about a month as over
time the alum can degrade the fabric.
- Measure and simmer your dyestuff for an hour using enough water so
your fabric can move freely, allow to cool.You may need to chop up
larger roots, such as when you use madder. Roots also like to be soaked
overnight for some of the darkest shades.This is best done before you
mordant or at the same time.
- Strain out any roots, shavings, etc.
- Add wet fabric and simmer for an hour, allow to cool in dyebath for
maximum color absorption. Be sure to stir periodically for even dyeing,
turning fabric frequently while simmering. You can save and re-use the
dyebath for lighter shades.
- Give the fabric a final gentle wash with synthrapol and rinse.
How To Dye With Natural Indigo
For 1 lb. of fiber or fabric you will need the following:
Important: Before starting any dye project you should always do a
test run on scrap fabric first. Dyeing with Indigo is a process with
many variables, and as with any new process, common sense dictates that
you always TEST FIRST if you have something specific in mind. If you are
more flexible, you will be enthralled with the range of beautiful
traditional blues you can get. You can also overdye Indigo dyed fabrics
with other natural dyes to get other colors. If you have a chemistry
student in the family, and they know how to handle chemicals safely, the
chemistry of getting to the blue cloth makes for a very interesting
project.
Pour powdered indigo into 1/4 cup hot water. Stir until dissolved.
Pour dissolved indigo into a large pot of water. In a separate jar,
dissolve the Soda Ash in some warm water. Add the Soda Ash solution to
the Indigo and stir. This increases the PH of the dyebath to prepare for
"reducing" the dye and making it soluble in water. Add half (1/4 oz) of
the Color Remover and stir gently. Heat to between 120°F and
130°F continuing to stir gently. The liquid should appear yellow or
yellow-green and may even have a bit of a â€scummy†appearance
– somewhat like a witch’s cauldron; this is okay. Let the
mixture stand for 20 minutes. If the water appears blue, too much oxygen
has entered the dye bath and you will have to add more Color
Remover into the bath and stir GENTLY to reduce the indigo. To get the
best tones from the indigo, you should avoid letting too much oxygen get
into the pot as it causes the dye to precipitate out of solution. This
means you must work much more slowly and gently than with other colors.
You may find it helpful to tie a line of thread to one corner of your
fabric before immersing it in the dye as this will make it easy to fish
your fabric out of the pot without stirring excess air into the dye
bath.
After the dye has steeped for 20 minutes you may then add your
fabric. The wet, pre-washed fabric can be compressed into a ball,
lowered into the dye bath and then allowed to expand. Again, stir
GENTLY. The first fabrics will only need to be immersed for a few
minutes to absorb the maximum color while fabrics added later may need
to stay in for 5 to 10 minutes. When the fabric is removed from the dye
pot, it should first look yellow-green and then turn blue after it comes
into contact with the oxygen in the air. This is where the dye is
"oxidizing" again, and becoming once more insoluble in water, which is
what makes it stay "trapped" in the fibers of the fabric. You can also
re-do the dyeing more than once - successive "dippings" and oxidizing
yields deeper and deeper blues, and is the best way to get dark color.
If instead you try to get a dark blue by one but much longer and more
concentrated dyebath, like you might with other dyes, most of it will
just wash out or rub off. When you have reached your desired depth of
shade, you need to wash out the chemicals and excess Indigo. As with all
dyes, wash out the fabric in Hot water and Synthrapol or Professional Textile Detergent
to get out the all of excess dye. This is a very important process, or
the dye will "crock" or rub off on you and you will look like you are
trying out for the "Blue Man Group". One thing that helps to have less
dye come off and less fading in the future, is after one brief rinse, to
put the fabric in a hot soak with Dye Fixative or Retayne for 1/2 hour (1 oz fixative per lb. of fabric). This causes more of the Indigo to stick to the fabric. Then do the Synthrapol wash and you are good to go. The fabric will fade less with successive washings also.
To get the best, most even dyeing results it will be easier to work
outdoors and with another person. When the fabric is removed from the
dye bath, you can hang it, or a fun thing is to take the cloth and
stretch it tautly from all four corners (like when folding a sheet) at a
vertical angle so the excess dye can run over the surface of the
fabric. Tilt the fabric back and forth so that the dye runs in all
directions over the fabric; this step is not a requirement but without
it the dye may strike unevenly and the result can look like a cloudy sky
with lighter and darker areas of blue. After a few minutes of exposure
to the air and the desired blue hue has been achieved, the excess dye
can then be rinsed off. If your color has turned out unevenly you can
repeat the dye process to help even out the color. Fabrics that are tied
or clamped as in Tie-dye or Shibori look fantastic when dyed with
Indigo.
