Cara mordan kain untuk ecoprint | how to mordanting fabric for ecoprint

Summary

In this tutorial, the process of mordanting fabric for natural dyeing and eco-printing is demonstrated step by step. The video covers essential materials like alum (tawas), soda ash, and water, providing clear instructions for preparing the mordant solution, soaking the fabric, and ensuring even absorption. The fabric is then left to soak for a couple of days before being dried. This easy-to-follow guide is perfect for those looking to explore natural dyeing techniques and create eco-friendly prints.

Takeaways

• 😀 Start by washing the fabric thoroughly to remove any dirt and debris, ensuring it is ready for mordanting.
• 😀 Use alum (tawas) for the mordanting process, with a recommended quantity of 900 grams based on the amount of fabric.
• 😀 Soda ash (soda abu) is another necessary ingredient, and 200 grams should be used for effective mordanting.
• 😀 Prepare 30 liters of water, adjusting the amount based on the fabric quantity to ensure full submersion.
• 😀 First, dissolve the soda ash in water and stir until it is completely dissolved.
• 😀 Then, add the alum and continue stirring to ensure it is well mixed.
• 😀 Submerge the fabric into the solution, ensuring the fabric is fully immersed in the liquid.
• 😀 Stir the fabric periodically while heating to ensure an even application of the mordant.
• 😀 Heat the mixture until it begins to boil, but avoid letting the water fully boil before removing it from the heat.
• 😀 Let the fabric soak in the solution for 1-2 days, then drain and air-dry without rinsing to preserve the mordanting effect.
• 😀 Once dry, the fabric is ready for eco-printing or other natural dyeing processes.

Q & A

What is the purpose of washing the fabric before mordanting it?

Washing the fabric is essential to remove any dirt or residues that may be left on the fabric fibers. This ensures that the mordanting process is more effective, allowing the fabric to absorb the metal ions more thoroughly.

What is the role of alum (tawas) in the mordanting process?

Alum (tawas) is used as a mordant. It helps bind the dye to the fibers of the fabric, improving the color absorption and ensuring that the dye remains on the fabric for a longer time.

Why is soda ash (soda abu) added to the mordanting solution?

Soda ash is added to adjust the pH level of the mordanting solution. This helps in the better absorption of the alum and makes the mordanting process more efficient.

How much water is used in the mordanting process, and why is this amount important?

30 liters of water is used in this process to ensure that the fabric is fully submerged and that the mordanting solution can properly interact with the entire surface area of the fabric.

At what temperature should the fabric be heated during the mordanting process?

The fabric should be heated until the water almost reaches boiling point, but it should not be allowed to boil completely. Heating helps the mordant solution to penetrate the fabric fibers evenly.

Why is it important to stir the fabric in the solution during the mordanting process?

Stirring the fabric ensures that the mordant solution is evenly distributed and absorbed by the fabric, leading to a uniform mordanting result.

How long should the fabric be left to soak in the mordanting solution?

The fabric should be left to soak in the mordanting solution for 1-2 days, allowing sufficient time for the fibers to absorb the mordant thoroughly.

Should the fabric be rinsed after mordanting?

No, the fabric should not be rinsed after mordanting. Instead, it should be directly hung to dry. This ensures that the mordant remains on the fabric, which is necessary for dyeing.

Can the mordanted fabric be used for purposes other than eco-printing and natural dyeing?

Yes, the mordanted fabric can be used for other purposes, but it is particularly suited for eco-printing and natural dyeing because of the way it absorbs dyes and maintains colors.

Why is it recommended to use 900 grams of alum for mordanting this amount of fabric?

The amount of alum used is based on the volume of fabric being treated. 900 grams of alum ensures that the fabric receives an adequate amount of mordant to properly bind the dye to the fibers.
