These photos were taken on Saturday while I was carrying out some experiments. I thought
this would be a good opportunity to share some of the reasons that I use
natural dyes - or
plant dyes to be specific.
Plant dyes offer a totally different experience to chemical dyes. Firstly, the aromas that come from my dye pots make the process very enjoyable. Madder is my favourite, which
produces a sweet smell when simmering on the stove. A subtle fragrance lingers
on the fabric even once it is dry. It's not noticeable to some people, but I
have a very sensitive sense of smell and I love sniffing my fabrics! The
fragrance is
very delicate and each dye is slightly different.
The next aspect that I really enjoy is the unpredictability of plant dyes.
When the dye washes out of the fabric it can produce quite surprising results.
For example, the logwood in the second photo has a pinky/beetroot tinge but
once the fabric is rinsed and dried, the final colour is a beautiful, muted
purple. Logwood always leaves small dark flecks on the fabric, which no amount
of stirring to dissolve the dye will remedy. These small traces from the
process must be embraced.
Natural colours are never flat or one-dimensional; the dyed fabric seems to
be "alive". I've heard that if you look at a piece of
naturally-dyed fabric under the microscope you will see all the colours of the
rainbow. A piece of fabric that appears purple, will actually be made up of
many colours that produce the over-all effect of purple. Synthetic colours, in
contrast, are totally flat.
Experimentation, which is the most exciting aspect of the design process, is
imperative with natural dyeing as you cannot predict how a colour will take to
a particular type of fabric. I keep a book of swatches and recipes so I'm able
to control my results as best as possible. However, the natural-dyeing process is dependent on so
many factors, including temperature and water pH, that it's very difficult, if
not impossible, to replicate colours with 100% accuracy. Besides, it is the
variation in results that is so intriguing. Chemical dyes were invented to
produce consistent results, but natural dyes offer so much more than this.
Indigo, I believe, offers the most magical dyeing experience. To dye with
indigo, the oxygen needs to be removed from the pot of liquid, which enables
the indigo to dissolve and attach to the fibre. The fabric first turns lime
green and once it has been taken out of the pot it starts oxidising and changes to a deep
blue. The colour change from green to blue never fails to excite me. The first
photo, above, shows indigo that has partially oxidised.
Finally, it's important to emphasise that plant-dyeing is not a quick
process by any means. It takes time to prepare the fabric before it's ready to dye. First the fabric is scoured (cleaned) to remove residues of oil and dirt, then the fabric needs to be mordanted (with the exception of indigo), to enable the dye particles to attach to the fibre.
The fabric goes through several processes before it even comes into contact
with any dye. All in all, the natural dyeing process takes several hours
longer than working with synthetic dyes. However, once you have fallen in love with
the process and the results, then you will realise that it’s worth it!
