If you want to change the colour of your curtains or simply brighten them up, you can do so with fabric dye. As these are usually bulky and heavy, you will need a lot of colour. Here are some tips to avoid disappointment and achieve good results.
1. Not all curtains can be dyed
It is possible that some curtains contain polyester and, if so, this cannot be dyed. The same also applies to the yarn used to make the fabric, which itself contains polyester.
It should also be noted that treatment with water-repellent substances during production can also negatively affect the end result.
2. Always follow the washing instructions
Every garment you buy has a label with washing instructions; this also applies to curtains. Consult this label to find out how many degrees they can be washed at and what the fabric composition is. Always pay attention to the presence of polyester, if the curtains are made of this material 100% of it will not dye. If, on the other hand, only a percentage is present, we still advise against dyeing because the result will still be unsatisfactory.
3. Washing instructions are not present
Handmade or custom-made curtains usually do not carry labels and washing instructions. If you have no idea of the composition of the fabric, test only a small part of it first and evaluate whether it is appropriate to proceed with dyeing.
4. Rehearse
Don't risk spending tens or hundreds of euros for nothing, start by buying a sachet of dye and test it to make sure the result is assured.
Look for a small portion of fabric to cut, usually near the top hem or seams. If there are excess seams, use those too, so you can test the dye on the yarn.
Put some dye powder in a glass and add hot water, let it dissolve well. Immerse the piece of fabric in the solution and wait about half an hour. Then rinse well and observe how the fabric has reacted. If the result is satisfactory, you can proceed to buy the colour of your choice to dye your curtains.
5. Experiment with different colours
Fabrics such as cotton, silk and nylon all react differently when dyed. The important thing is always to consider the base from which you start. Using a soft yellow on a black fabric is different than dyeing a yellow fabric black.
That is why we always recommend trying out different colours. Try darker and lighter shades, or create combinations between different colours.
You can fill several glasses with different colours and combinations. You don't need to use a lot of colour, one sachet will suffice for 10 different servings.
Have fun and experiment, but be sure to try it out on old fabrics or clothes first.
6. The water temperature is too low
The ideal temperature for dyeing fabrics is 90°C. Curtains can usually be washed at a maximum of 30-40°C and often tend to shrink even at these temperatures. It is difficult to achieve good results by dyeing at low temperatures because the colour does not adhere well to the fabric fibres and is therefore too soft.
7. Let the fabric soak for longer
If you dye at low temperatures, keep an eye on the intensity of the colour on the fabric by pulling it out of the dye bath or observing through the washing machine's porthole if the water is the same colour as the fabric.
If you see that the fabric remains light-coloured and struggles to dye, you can leave it in the water for longer, even overnight if necessary. The dye will only be perfect when the colour of the fabric no longer changes. If you dye in the washing machine, you can stop it halfway through the wash and leave it in
soaking, ensuring that the water in the basket covers the entire load and that it is turned over from time to time.
