How to prevent fading of eco-print fabrics

All dyed fabric will fade eventually, from washing and sun exposure. Eco-printed cotton does fade more quickly than synthetically dyed cotton but there are a few ways you can reduce this to enjoy your fabric for longer.

I find that machine washing eco-printed fabric is fine, although I recommend hand washing for very special items. More important is to use a mild washing detergent. Most washing powders and liquids are too harsh and will quickly strip off the natural plant dyes. I use soap nuts, which can often be bought from health food stores or co-ops. Simply soak the soap nuts in boiling water for a few minutes, then add this liquid to the washing machine.

UV rays in sunlight will also fade dyed fabric over time. After washing eco-printed clothing, dry them in the shade or at least turned inside out. Bring them in as soon as they have dried and store in the dark. Also, try to avoid wearing eco-printed clothing if you will be in direct sun all day.

I have some eco-printed clothing that is still looking quite good after a couple of years of gentle wear. Once they become faded, clothes that have previously been eco-printed also tend to re-dye well. Re-mordant the fabric then dye as usual. Faint traces of the previous print can be seen on the cotton sample below, providing a lovely ghost effect.

Good leaves to use for eco-printing: experiment two

I get asked a lot if the method I described in my ebook will work for non-eucalypts. These samplers are a good example of the results you can get using different types of leaves. Following on from the first experiment I documented, these leaves were left to soak for about 2 months before I used them, and it really made a difference! Some of the leaves printed better than others, but I really enjoyed seeing how so many different types of leaves, some native to Australia and some introduced species, can produce such clear and beautiful prints.

I sandwiched the leaves between two different pieces of cotton, to observe the difference in the prints produced from each side of each leaf:

Green eco-printed leaves

These prints are of the ‘sky-facing side’ of the leaves (where applicable). Most produced a lot of colour, and the leaf outlines and veins are crisp and clear. They are printed onto a yellow woven cotton, which has created beautiful green hues for many of the leaves, in contrast with the bluer prints below.

These prints are of the ‘earth-facing side’ of each leaf, on a white stretch cotton. Some still printed very clearly, especially the maple, oak and blackberry leaves, while others produced only faint outlines.

 

Interview with the Studio Fae Project

I was recently interviewed by the lovely Skye Scott from The Studio Fae Project. Skye is currently teaching herself floristy and she interviewed me about my process and challenges in being a self-taught eco-print artist. I really enjoyed reflecting on my journey so far.

Natural dyeing with avocado seeds

I’ve been experimenting with naturally dyeing solid colours, aided by Rebecca Desnos’ beautiful ebook. I recently tried dyeing soy-mordanted cotton with avocado seeds (avocado stones/pits). When I first put the fabric in the dye bath I didn’t quite believe it would do anything. The dye looked quite pale. But I left it for about 30 hours and it slowly turned this vivid pink! Avocado stone dye- dyeing with avodado seeds/pits on soy mordanted cotton I tried eco-printing over this fabric but didn’t have much success. But I was able to create a beautiful resist effect on some watercolour paper. I covered some iron-mordanted watercolour paper with gum leaves, then laid a piece of my avocado-dyed cotton on top, pressed it between 2 tiles and boiled for an hour. Some of the avocado dye transferred to the paper and the pink turned to purple in reaction with the iron.

Mordanting with blood

I’ve been curious about mordanting with blood ever since I read India Flint’s passing reference to it in Second Skin. I’m not a squeamish person and I have ready access to a cruelty-free form of blood each month with my menstrual cycle, so I thought I would give it a go. I wondered if it would give similar results to other protein mordants, or whether the particular properties of blood would effect the results.

Mordanting fabric with blood

To prepare the fabric, I simply soaked it for about an hour in the water I had soaked my cloth pads in. Then I lay it flat to dry and let it set for about a week before eco-printing.

The mordant definitely worked, although the prints were fairly light. Next time I would try to use more blood and soak the fabric for longer to create a stronger mordant. I might also try a series of ‘dipping and drying’ as is done with soy mordants, and see if this gives more vibrant results.

Eco-printing on wool versus cotton

I prefer eco-printing on cotton rather than wool for a few reasons. Cotton clothing is easier to find at op-shops, and in a wider range of styles, than wool. Upcycling clothing that already exists feels like the most ethical way I can do a lot of eco-printing, so it makes sense to go with what is readily available. I also love the wider range of colours and textures that I can get on cotton. Eucalyptus leaves mostly print solid colours on wool, whereas prints on cotton often have extra details like blue dots.

Eco-printing on wool versus cotton
When I was writing my ebook, I wanted to show the difference between wool and cotton eco-prints. I did a range of small samples with the same leaf sandwiched between one piece of wool and one piece of cotton. It was so interesting to see the different colours that came from the exact same leaf on the different types of fabric. All of these photos show the wool on the left and the cotton on the right.

Eco-printing on mordanted wool

Some of the mordant on the cotton did transfer somewhat onto the wool, seen most starkly in the dark borders around the leaves and gumnuts above, so I can’t expect the same results with these leaves on unmordanted wool.

Eco-printed wool and cotton colour comparisons

I was especially excited to get some more insight into which leaves dye best on wool. Lots of the eucalyptus leaves here in the Blue Mountains dye quite pale, especially without any mordant. I noticed that I got beautiful bright oranges from silvery-blue leaves, while the greener leaves dyed pale yellows on the wool. Almost all of my local gumtrees have dark green leaves, so I guess it’s lucky I’m not often wanting to get bright prints on wool!

Bright orange and brown gum leaf eco-prints, from the same leaves on different fabric

Even more interesting, the leaves that dyed orange on wool consistently dyed brown on (iron-mordanted) cotton, while the leaves that dyed pale yellow on wool dyed blue or blue-green on cotton. I know that some green eucalyptus leaves do dye brilliant reds or oranges, but my local ones don’t seem to have the right chemical components for that.

Gum leaf and gumnut eco print experiments

I still have a lot that I want to investigate about different types of gumleaves and what factors influence which colour they dye, but this was certainly a useful experiment and a very good way to get to know more about my local leaves.

Good leaves to use for eco-Printing: experiment one

I’ve been working exclusively with gum leaves for the past few years. I love everything about them- their shape, their smell, the amazing range of colours and textures I can get from them. But I’ve decided to spend time this year experimenting with other types of leaves to eco-print with. I’m curious about how well the method I described in my ebook will work with different leaves.

For this first experiment, I did a leaf walk around Hazelbrook, gathering from a wide range of native and introduced plants. I collected 2 leaves or small branches from each plant, so I could compare the difference between using them fresh and letting them soak for a while.

The leaves were placed on mordanted cotton, wrapped into bundles then boiled for about an hour. Some leaves would do better with lower temperatures, but I was processing eucalyptus bundles at the same time and they definitely need boiling to properly release their colour.

The bundle I did with fresh leaves had a few promising prints, especially the dark blue maple leaves at the top, and some quite nicely outlined grevillea leaves (at least I think that’s what they are, I didn’t take notes as I gathered!). Overall, many of the leaves produced indistinct prints and bled out a lot of colour which turned the fabric quite dark.

I let the extra leaves I had gathered soak in water for a month before repeating this experiment. I got many more clear leaf prints this time. Some of the colours were quite incredible when I first unwrapped the bundle. The two ferns were almost light aqua, a colour that I haven’t seen in an eco-print before. All the colours have dulled a bit since unwrapping. Next time I might try leaving the bundles for at least a few days before unwrapping, to let the colours develop further.

The top left print is from acacia leaves, either black wattle or similar. The bottom right print is a grevillea leaf, and the others I’m not sure about.

Along with more maple leaves, I was delighted to get this clear fern print. I’m excited to try more things with different fern varieties as they have such distinctive shapes. I have a selection of local fern leaves currently soaking, ready for future experiments.

How to Eco-Print on Cotton

Eco-printing on cotton can be a bit more fiddly than eco-printing on wool or silk. Cellulose fibres don’t take up plant dyes as easily as protein fibres do. I have spent about 5 years experimenting with how to best prepare cotton and leaves for eco-printing, and am now able to fairly consistently get bright, clear leaf prints.

Natural dyeing with eucalyptus leaves on cotton

I am delighted to be releasing my ebook, Gum Leaf Alchemy, to share this method with others. The process I have developed works particularly well with eucalyptus leaves, but I have also been getting some good results from experiments with other types of leaves, from both native Australian and introduced plants.
