How to remove heavy areas of rust from my rusted fabric?

Question of the Day: How to remove heavy areas of rust from my rusted fabric?

You neutralize the rusted fabric with baking soda water first and then if there are chunks left behind, ok I leave mine because I like the look, you can put a baking soda paste on the fabric to help break it down. Keep in mind that sometime...s the rust chunks simply do not go away but it's worth a try.

Rubbing in with a toothbrush also helps, I have done this but gotta admit I have one piece of fabric that was super chunky and decided to work with it instead of trying to get rid of the rusted areas.

Indigo Dyeing

Dye Materials Needed

1 ounce Indigo extract or Indigo chunks
1 cup Soda Ash or Lye (I HIGLY recommend using Soda Ash NOT Lye~!)
2 Tablespoons Thiourea dioxide or Thiox
Water

Equipment needed:

Respirator – you only get one set of lungs! Wear a respirator when handling dye powders, mordants, and dye assists~!
Gloves – wear heavy duty kitchen or dyeing gloves when handling the indigo ingredients (See safety Instructions Below)
Stock Pot 18 quarts or bigger, can be Stainless Steel or Enamel the indigo vat will react with aluminum so I don’t recommend using aluminum pots for creating the vat.
Scale for weighing dyes and chemicals – again studio dedicated!
Measuring spoons, measuring cups, wisk for stirring
Jar – wide mouth pint jar for making indigo paste
Spoon, studio dedicated, for stirring the vat
Tongs for retrieving your fabrics, fibers, etc.
Lingerie bag for small items you wish to find in the vat again the bag makes them easier to retrieve
Water for your vat, rinsing, and for oxidizing
Vinegar – helps to restore the pH balance of wool and silk fibers/fabrics
pH papers/strips for testing the pH of your vat.
Heat source
Clothesline for hanging fabrics onto to help fabric oxidize faster.




Natural Indigo Chemical Reduction Mini-Vat Instructions:

1. READ Safety Instructions before Beginning the Indigo Vat!

2. Fill your vat container with water you don’t need to heat the vat at this point. ALLOW TO SIT OVERNIGHT, doing this allows the oxygen to dissipate from the vat.

3. Place 1 ounce Natural Indigo powder (if you are working with hard chunk indigo it will have to be ground down first) into a suitable container.

4. Add just enough hot water until you get a paste – preferably lump free (I use a dedicated wide mouth pint jar for this solution.

5. Add soda ash or lye to the vat water - NEVER add water to your soda ash or lye ALWAYS add the soda ash or lye to the water!!!

6. Slowly add the indigo paste to the vat solution

7. Stir to dissolve NOTE this may take quite a bit of stirring, heating the vat at this point also helps with dissolving the paste faster.

8. Next add thiox to the vat solution stir very little so as to avoid adding Oxygen to the vat.

9. DO NOT BOIL YOUR VAT as this will cause bubble formation and will introduce Oxygen into the vat.

10. REMOVE HEAT after 30 minutes

11. Cover vat and allow to sit until reduction is complete.

12. Reduction is complete when your vat turns a yellow to yellowish pea green color.

13. If your vat is still blue after 24 hours then you have too much Oxygen in your vat add thiox to the vat in small increments, a few grains of thiox at a time, to further reduce the vat.

14. If you reduce the vat too far then gently stir the vat with one or two swirls of the spoon and allow to sit for 30 minutes.

15. You will need to test the pH of the vat to see if the pH is correct

16. pH should be 10.0 – 11.5
· cottons 11.0-11.5
· wool and silk 10.5-11.0 preferably closer to 10.5

17. Adjust pH by adding small amounts, half teaspoon at a time, of soda ash to your vat, even is you created a lye vat do NOT add more lye to the vat at this point.

Rust Dyeing

Rust Dyeing by Kimberly Baxter Packwood © 2001

Rust dyeing is a surface design method that adds dimension to your fabrics and fibers. I use the technique predominately on cotton or silk fabrics. Natural fibers take the rust colors better than synthetic fibers.

You can rust dye onto commercially dyed and/or printed fabrics. However, fabrics dyed using synthetic dyes, or those dyed with natural dyes take rust dyeing best as they usually do not have anti-stain coatings on them.

When applying rusty objects to naturally dyed fabrics the colors will change. Iron, i.e. rust, is a modifier and is used as a mordant with natural dyes.

Modifiers change the existing color via shifts in the pH levels. An example would be hibiscus or cochineal, each yield a red color, when you add iron they shift from red to purple. A minute amount causes this color change.

You can place rusty objects next to wet fabric and acquire rust patterning over time. However, vinegar will speed up the rusting process, it aids in breaking the rust particles free from the object that is rusting.

Rusting occurs normally due to oxidation, i.e. contact with the air. Be patient. Rust dyeing with water takes about a week. Using vinegar produces color in less time usually twenty-four hours.

I use straight vinegar and all sorts of rusty objects to acquire my rust dyed patterns. Old nails and wire work well for this technique. Wire can be used for bound resist techniques, especially when wrapping the fabric around a rusty pipe. Or you can simply lay the wire in a loose pattern on the fabric and rust it in that manner.

Pole wrapping and bound resist techniques work well with rust dyeing. Simply wrap your vinegar-saturated fabric around a rusty pole, being careful not to tear the fabric, scrunch and otherwise manipulate the fabric to created patterning.

You can sprinkle iron mordant or iron shavings onto your fabric for other patterning. Iron mordant is preferable to shavings. Shavings are often sharp things that can cut you or the fabric. Metal shavings may be coated in machinery oil which would put unwanted stains onto the fabric.

If you like your rusty pieces and want to push the rust dyeing technique further, rinse the fabric and neutralize it in salt water, rinse it again and then rust the fabric once more. This will help prevent the fabric from rotting through.

Natural rust is an iron oxide. It comes in about ten or more natural colors depending on what it is in the neighboring the iron ore. Wear gloves and a mask when working with it.

You can mix a small amount natural rust with water, I generally use one teaspoon rust to one cup liquid, or with soy milk to paint fabric. Stir well. Let it sit for 24 hours to ensure that all of the color will dissolve. Then apply the rust solution to the fabric. Use a old brush you can dedicate to this kind of project. Natural bristle brushes work best with this technique allowing the liquid to wick up the bristles and not leave a mess on your fabric. Cure the fabric dry for 24 hours. Rinse and neutralize your fabric in a saltwater solution.

When using the rust technique if you want the process to stop you need to neutralize it with a salt-water solution. Dissolve about 1/4 cup salt into four gallons of hot water. I do this in a five-gallon bucket. Soak your fabric in the salt water about fifteen minutes. Wash the fabric using a non-phosphorous soap or a mild color free shampoo.

I teach workshops on rust dyeing, several workshops on natural dyeing and several for clay/pigment dyeing
