There are so many techniques for special dyeing effects. Here are the useful methods. We will see more about other method in my next blogpost.  

• Tie Dye
• Shibori
• Ombre  
• Dip Dye
• Shaded
• Hand Paint
• Resist
• Batik
• ice dyeing 
• spray dyeing 

Among these, I think ice dyeing is a very interesting one. I searched and found that there are so many posts, articles, and videos as well, but these all are done on cotton using cold brand reactive dyes.
That procedure is very easy, as the cotton or silk can be dyed without heating or steaming.
When we use acid dyes, it becomes a bit difficult process, as acid dyes require steaming to fix the dyes on fiber.
So let's start the process.
Soak the scarves for at least 15 minutes using acidic acid (or vinegar). Let the PH be around 5, adjusted with acidic acid. Use 3-4 tablespoonfuls of common salt.

Arrange some ice cubes. Squeeze the scarf and make it semi-dry. Let it be a bit moist. If the scarf is very dry, it creates a problem in the migration and penetration of dyes. Basically, water is the main medium of dyeing here, we are selecting ice as the medium. The amount of ice required is as per the depth of the shade. if we require dark shade, then we should use more ice. Put a semi-dry scarf into a small pot, making some rough folds. Please don't use excess ice, calculate the amount of ice that will be absorbed by scarf only. Excess ice could ruine the pattern. At the end of process there should not be any water, let the melted ice water be take by the scarf only.

First, put the ice covering each and every part of the scarves. Do not leave any part uncovering the scarf. Remember to make random folds and pleats; this folding technique makes scarfs beautiful after dyeing. Here you can apply tie-dye and shibori folding techniques also.

Put the acid dyes powder randomly. If you want to have some particular color on any part of the scarf, spread only that color on that area. If colors are mixed together, some different colors will appear. for example, if you put red and blue in the same place, then violet or purple will be seen after dyeing. Here I have used red, blue, green, and yellow colors.

This process is automatic. When the ice starts melting, dyes also start spreading. No human effort is required. The powder dyestuffs work amazingly. I said it automatically because ice, along with color, goes inside the fiber. We can't let it stop and divert to some other part. I also did it for the first time; that's why I was also curious to see the color-mixing effect.

Result after 24 hour

I have left it for 24 hours. When I did, it took 24 hours to melt. I did it in winter. Maybe it melts fast in the summertime. But leaving at 24  is the best idea, even in summer. Dyes penetrate perfectly if we extend time. The next morning when I take it out from the pot, it looks as shown below.

Doing Steaming is difficult at home. Printed or painted textile steaming, also known as ager done by ager machine, is used in textile processing factories. Here I am going to do it by a domestic method. The basic purpose of stemming is to send saturated steam to the fabric. The domestic pot, as explained below, would be sufficient for fixing the dyes in fiber. It has to be placed in a steaming vessel so that no condensed water falls on the fabric.
