PREPARE
FABRIC FOR NATURAL DYES(PFND)
You need to prepare your clothes before starting the dyeing
process. Wash the cloth first. However, it should not be dry, it should be
damp. Then prepare your stabilizer or "mordant". This helps the
fabric to absorb the natural color more easily. For berries, you have to use
salt and for any other plant ingredient, you can use vinegar. Here are the
measurements:
·
Salt: dissolve ½ cup salt in 8 cups cold water
·
Vinegar: blend 1-part white vinegar to 4 parts cold water
Leave your wet fabric in a stable solution for one hour.
When done, rinse with cold water. Then, it’s time to dye the fabric.
World the best Process for Natural Dyes.
Before you start, cover the surface of your work area with
newspaper. Also, I use plastic sheeting because I don’t want to dye my
countertops. Be sure to wear gloves so you only color the fabric, not your
hands. Then, prepare your dye.
The
Process
1.
Place the plant material in a large
non-reactive pot (like stainless steel or glass). Remember the dye could stain
some pots and spoons, so use these only for dyeing.
2.
Fill the pot with twice as much
water as plant material.
3.
Simmer for an hour or so, until you
get a nice dark color.
4.
Strain out the plant material and
return the liquid to the pot.
5.
Carefully place the fabric in the
dye bath and bring to a slow boil. Simmer for an hour or so, stirring once in a
while.
6.
Check your fabric. Remember, it will
be lighter when it dries. An hour should produce nice color, but darker hues
can be achieved by allowing to sit longer, even overnight. Turn the pot off
after an hour and allow the fabric to sit in the warm water as long as needed.
7.
When you get the color you want,
take the fabric out and wash it in cold water. Expect the color to run some as the
excess dye is washed out
8.
Dry as usual.
MERITS AND DEMERITS OF NATURAL DYES
ADVANTAGE OF NATURAL DYES: -
Ø Health and safety aspects of natural colors: Although all-natural colors are not 100% safe, they are less toxic than their synthetic parts. Many natural colors like turmeric, asparagus, and saffron are allowed as food additives. Many natural colors have pharmacological effects and potential health benefits.
Ø They are derived from renewable sources.
Ø Natural dyes, there is no eliminated problem as they are
biodegradable.
Ø Virtually no reaction or mild reaction is involved in its
preparation.
Ø They are not sophisticated and compatible with nature.
Ø Many
natural dyes have the advantage that, although their wash resistance rating is
very low, they do not stain the fabrics attached to the laundering process due
to the color-nature of the dye on the fabric. The exception is yellow, which
shows strength for cotton.
Ø Natural dyes are affordable.
LIMITATION OF NATURAL DYES
Ø
The complexity of the textile dyeing process.
Ø
Shadow
reproducibility
Ø In addition to these, there are other technical defects of natural color:
These are: -
Ø
The
number of suitable pigments is limited
Ø
The great difficulty in pigment mixing
Ø
There
are non-Standard.
Ø
Insufficient
degree of fixation. Its mean color fixation is a great problem
Ø
Few
features insufficient visibility with some exceptions
Ø Water pollution by heavy metals and
large amounts of organic matter.
