Dye Classes and Color Harmonies Class, June 2014

A lot of folks have been interested in dye classes lately, and I'm happy to announce that I have two on the calendar for this summer - plus, a color harmonies class as well!

On June 6-7, 2014 I'll be offering a cellulose dyeing class at the Hoosier Hills Fiber Festival in Franklin, Indiana.   In this class we'll be dyeing plant fibers [cotton, rayon, linen, tencel, bamboo] using cold water dyes.

The following weekend, June 14, 2014, I'll be teaching dyeing at White Violet Center at St. Mary of the Woods [just west of Terre Haute, Indiana].   In this class we'll be dyeing animal/protein fibers [wool, alpaca, llama, silk, soy silk, etc.] with acid dyes.  As a prelude to this class, I'll be teaching a Color Harmonies class in the morning with the dye class in the afternoon.   

Here are the full descriptions of the classes and links where you can register.  

1.  DYE CLASS: Fibers to Dye For, Cellulose Fibers [Plant Fibers]
2 part class: June 6, Friday 1-4 and June 7, Saturday 9-12
 
Hoosier Hills Fiberarts Festival
June 6-7, 2014

Johnson County Fairgrounds. Franklin, Indiana.
Yarn, roving, spindles, etc. [www.hoosierhillsfiberfestival.com]
Register at link above.

Learn how to dye plant fibers in rainbow skeins in your very own colors!  No previous experience needed!  This workshop will give step by step instructions on how to hand paint your own beautiful skeins of cotton, rayon, tencel, linen and other plant fibers using fiber reactive dyes.  Students may dye up to one full pound of yarn or fiber.  This is a two part class beginning the afternoon of Day 1 (with an overnight break so the skeins can batch) and finishing during the morning of Day 2.   Day 1:  Go over types of cellulose fibers and types of dyes, and safety procedures.  Mix the soda solution and dyes and paint skeins.  Skeins will batch overnight.   Day 2:  Rinse your skeins and go over how different types of fibers behave, common problems, resources and even a bit of color theory if time permits.  Students are welcome to bring up to one pound of yarn or fiber or a pre-wound warp to class.  Make sure it's cellulose/plant fiber.  


[Note:  This class is not for animal fibers.  These dyes do not work on wool, alpaca, angora, nylon, soy silk or animal fibers.]

2.  CLASS:  Color Harmonies
3.  CLASS:  Dyeing on Protein Fibers with Acid Dyes
June 14, 2014
White Violet Center, St. Mary of the Woods College. Terre Haute, Indiana.
Register for classes at www.whiteviolet.org.

Morning:   Color Harmonies: Color is one of the most magic aspects of art.  This class will help you take the mystery out of deciding which colors go together and how.   Topics will include basic color theory, using color tools, wheels and books, classic color combinations, etc.   Expect to laugh a lot as you practice putting colors together and using your new skills.  

Bring with you:  Photos or things with color combinations that you really like, photos or things with color combinations that you really don’t like.   Feel free to bring whatever color tools, books, swatches, yarn, etc you already have that you’d like to practice working with.

Afternoon:  Dyeing on Protein Fibers with Acid Dyes:
Explore the use of acid dyes to turn your 
stash of ‘boring’ protein yarns and fibers into designer yarns and fibers that you won’t be able to wait to knit, weave or spin up.  You will learn how to put several colors onto a skein to make variegated yarns as well as learn to do immersion [single color] dyeing.  We will dye with acid dyes [very safe and mild!] on wool, mohair, alpaca, soy silk, nylon or silk  fibers.   Students may bring white or natural yarns or bring colored yarns to overdye.   Overdying is a wonderful way to put pizzazz in a project.

[Note:  This class is not for plant fibers.  These dyes do not work on cotton, tencel, bamboo, rayon, linen or other plant fibers.]

Sun Dyeing

ANNUAL HOT WEATHER REPOST:

It's been hot here.

Blistering heat.  High humidity.   No fun for people or critters, but perfect weather for sun dyeing.  It's easy and a fun summer activity for kids.

Sun dyeing is for fibers that need heat to set.   Protein fibers:  Silk, wool, mohair, angora, alpaca, soy silk,  nylon.

Yeah, I know that nylon isn't protein, but it dyes like protein.  




This is what you need:

  • glass jar 
  • 4 colors of dye:   You can use kool-aid/drink mixes, food coloring, cake coloring, or acid dye.   Remember, this is America.  You can use how many ever colors of dye that you want.  You can combine different types of dye.   You can even use kool-aid with sugar if you want, but I don't recommend it because it makes things very, very sticky.   Use the drink mix packs without sugar.
  • Acid of some kind:  citric acid [not necessary if you use drink mixes - they have citric acid in them already.], vinegar, etc.
  • fibers or yarns that will fit into your glass jar, divided into three piles. 

This is what you do:
  • Sprinkle some dye in the bottom of the jar.  Don't be OCD about it, just sprinkle.  Be generous.
  • Put a third of your fiber in the jar.  
  • Sprinkle some dye over it.   
  • Put another third of the fiber in the jar.   
  • Way over on one side, sprinkle another color of dye.  
  • On the opposite side, sprinkle another color.   
  • Put the last third of your fiber in and sprinkle another color of dye on top.  
  • Sprinkle with citric acid or dump some vinegar in.
  • Fill the jar with hot water out of the tap.   Fill it until all of the fiber is covered. 
  • Let sit in sun for a day or so.  I covered mine with loose tops to keep the bugs out and the ducks from drinking it.   Eew.
  • You'll notice that the water will become clear around the yarn - that tells you that the dye has attached to the yarn out of the water.   That's good!
  • Rinse well and hang to dry. 
In the pic above, I used 6 skeins of nylon ribbon in each gallon jar.    In the left jar I used forest, burnt orange, navy, leaf and yellow dyes.   In the right jar I used violet, fuchsia, turquoise and bright red dyes.   I let them cook for a day and a half before I rinsed them.


The green ones got a little dark.  I dumped quite a bunch of the forest dye in the bottom.  

That's how it goes.  You're never quite sure how things will turn out.   Remember -- that's the fun of it!




The fuchsia and purple ones turned out like this.

Every skein is different.   I love them!



Now.....what to do with them....hmmmm.

Dye Studio - Dyeing with Acid Dyes

So you're ready to play with acid dyes on protein fibers!  Good for you!   If you want all the same color on your skein, then you need to follow the dye manufacturer's instructions. See yesterday's post for a list of places to get acid dyes.  If you want to paint different colors on your skeins, then here are some instructions.

This is what you need:
Bottom of steam pan with rack
  • Gloves:  thin ones to dye with AND heavy ones to handle very hot fiber with.
  • Apron and dye clothes.
  • Bucket big enough to hold your fiber loosely in water.
  • Fibers:  protein fibers like wool, etc.
  • Acid dyes:  One Shot, Jacquard, Kool-Aid, etc.
  • Acid:  vinegar or citric acid
  • Trash bag to cover your table.
  • Squirt bottles or brushes to put the dye on with.
  • Large pot with lid to boil water in.
  • Rack that fits inside the pot to hold the fibers out of the water while they're steaming.
  • Plenty of old towels or rags.
As I mentioned in the last post, the basic steps for hand painting with acid dyes is this:
1.  Wet out your fibers in hot water with acid in it.
2.  Mix up your dyes into dye solutions
3.  Paint your skeins with the dye
4.  Heat the skeins
5.  Cool the skeins
6.  Rinse and dry. 

But you want more details, right?   I'll take it step by step.

1.  Wet out your fibers in hot water with acid in it.

How much water?   Enough to cover your fiber well.
How hot?   This is going to be heat set - start the heat now.   Use hot water.
How much acid?   1 Tablespoon of citric acid or 2 Tablespoons vinegar per gallon is plenty.   It only has to be a little acid.

Put the acid in the hot water and then the fiber.   Let it sit for 15 minutes or so while you get everything else ready.

2.  Mix up your dyes into dye solutions.    It's a good idea to start heating your steam water now.   By the time you're done with the dyeing, the water will be boiling and ready to go.

How strong should the dye solutions be?   That depends on how dark/bright you want your colors to be.

1% dye solution gives bright/dark colors.
.5% gives nice medium shades. 
0.1% solution gives good pastels. 

Remember:  There are no RULES.   Make things as dark or light as you want!

3.  Paint your skeins with the dye.

When you're done with the top, squeeze the dye through the skein by pressing and squeezing a section at a time along the skein, then flip it over and paint the other side.

Squeeze the dye through one last time.

NOTE:   Gravity will pull the dye through the skein and it will puddle on the bottom.   You'll get darker colors wherever it puddles.    If you can't deal with that, then grab a dry towel and soak up the puddle of dye.

4.  Heat the skeins.
I use 2 large veg pans and a stove rack to steam on.

Gently lift the skein onto the steamer rack.    REMEMBER:  Dye wicks quickly and easily through protein fibers.  The more you move the skein, the more the colors will move.   Magical and beautiful things might happen.   If you don't want color movement, then move things as little as possible.

Put the rack over the steam, cover and let steam for 20-30 minutes.   If you're only doing one skein, then you can get by with 15 minutes.   If you're doing a bunch of skeins, it might take 50 minutes.    Don't skimp on the steam time.

REMEMBER:  Don't let your steamer run dry.   [No fun!  I've done it.   My steamer has the scars to prove it.]

When the steaming is done, turn off the heat.   Lift the lid by opening the side AWAY from you first.    Steam burns are very painful!

One batch cooling while the next steams
5.  Cool the skeins.

Take your fibers out of the rack and let them cool.   Let them cool until you can touch them bare handed.   It'll take longer to cool the center, so spread them out a bit for cooling.

6.  Rinse and dry.



REMEMBER:   You don't want to felt your yarn!  

Fill a bucket with very hot water.  It's fine to use any temp that is warmer than your skeins.   Lay your fibers in the bucket.   If the dye took well, there should be very little bleeding at all, if any.   Let it sit for a minute or so.  Do not agitate!  You don't want felt.

Nylon dries fast!
Dump the bucket and fiber gently into the sink.   Let the water drain off.   Press down on the yarn to get as much water as possible out of the fiber.

Spin out the excess water by putting the yarn in your washing machine and doing a SPIN CYCLE.   NOTE:   Do NOT use a full rinse cycle - that will wet your yarn, then agitate, then spin.   Use only the spin cycle.

OR, you can just roll the yarn in a towel and squeeze hard to get as much water out as you can.

Hang it to dry.


Troubleshooting:

* I followed the directions but all the dye rinsed right out!    

Your yarn wasn't protein.   The dye knows!    And believe me this has happened to all of us!    I just got a batch of yarn that we thought was nylon.    The dye rinsed right out of it.    Surprise!   I tested it with MX dyes and turns out it was a very shiny, clear, rayon.   Oops.   But not a crisis.

*  The dye takes, but a lot of it rinses out!

You need a longer steaming time.   I had a terrible time dyeing alpaca and wensleydale until I doubled the steam time.    Some fibers take their time opening up and taking the dye.   Give them plenty of steam time.

*  The yellows are rinsing out!

It's a weird fact that some fibers don't like certain dye colors.   My issue is yellows.   Yours might be some other color.   Wool generally takes everything just fine.   Alpaca and wensleydale, which is a rare breed wool, don't like my yellows.    I doubled the steam time and that helped a lot.   I still lose some yellow, but I can get it out in a single rinse. 

If you run into other problems, you're welcome to let me know!    Happy dyeing!

Acid Dyes

 Frost Ribbon dyed with acid dyes
As I mentioned yesterday, you use acid dyes to dye protein fibers.

Protein fibers are animal fibers:   wool, mohair, alpaca, angora, dog, llama, camel, buffalo, silk.

Protein fibers require heat and acid to set the dye.    Alkali will break down and damage protein fibers - think 'bad perm'.

Use Acid Dyes to dye protein fibers, soy silk and nylon.    Acid dyes sound scary, but they are very safe.   They are called acid dyes only because it takes a little acid to get the chemistry right so the fibers will take up the dye.   I use citric acid.  You can use vinegar or ammonium sulfate [fertilizer, sometimes available in garden stores.]

Acid dyes are very efficient.  97% of the dye takes up, so if you do things right, it'll only take one rinse to get the rest of the dye out - very important if you're trying not to felt your wool!   Also, acid dyes last for a very long time in liquid form.  You can mix up your dye solution and let it sit.   And sit.  And sit.   For more than a year.  [I know; I've done it.].

Here are some places to get acid dyes: 

My favorite acid dyes are Washfast Acid Dyes from www.prochemical.com.  They have a couple of other types of acid dyes, too and any of them will work beautifully on your fibers.   Just read through the basic instructions and choose the type you like best and go with those dyes.  One Shot dyes are fun, easy and in smaller quantities that are affordable enough that you can get several colors to play with.

You can also find acid dyes at www.dharmatrading.com. They carry Jacquard Dyes, which are lovely, easy to mix up and reasonably priced.  

If you're just starting out and want to really play before you make a big commitment or if you have children at home and don't want to risk a dye accident, then I suggest using Kool-Aid [or other drink mixes].   Kool-Aid is made with food grade acid dyes.   Use the unsweetened kind!

You can also use cake decorating gels.    Here's a challenge:  use the black and see what happens.  [Hint:  you don't get black....]

I rarely do immersion dyeing.   My yarns are hand painted.  The basic process for dye painting protein fibers with acid dyes is this:
1.  Wet out your fibers in hot water with acid in it.
2.  Mix up your dyes into dye solutions
3.  Paint your skeins with the dye
4.  Heat the skeins
5.  Cool the skeins
6.  Rinse and dry. 

More details on this tomorrow, with pics of my set up.

Happy dyeing!
