Textile Industrial information of dyeing with turmeric

• here, I m going to explain about, how to dyeing with turmeric, Natural dyes has been used in most of the ancient civilization
such as India, Egypt, etc. In India, the use of natural dyes for dyeing, painting and printing.
mostly natural dyes are used for dyeing, printing and painting
in India. they are extensively used as cosmetics for woman.
some examples are heena/ mehadi for decorating the palms
and soles young maidens.
• ‘surma’ to enhance the effect of eye lashes. Natural dye is also used in food and confectionary.
ex; saffron, turmeric, kashmiri chilli, and ratanjyot. Because of the wide use, these dyes have become a part
and parcel of Indian life.
• the use of natural dyes for textile dyeing almost disappeared, due to wide range of synthetic colours available, with good fastness properties at low to moderate cost.

Turmeric dyeing with turmeric

A natural dye is extracted from turmeric and used to dye
cotton at different conditions.
Then the fastness properties of the dyeing with different
dyeing techniques are compared. the dye is found good saturation
and rubbing fastness, but poor washing and light fastness properties
on cotton,
Applied without any mordant. when dyeing is implemented with
mordants, washing fastness and light fastness properties show improved
while rubbing fastness exhibits deterioration.

Mordanting of natural dyeing:

There are two kinds of natural dyes: substantive and adjective.
SUBSTANTIVE dyes need no mordants to help them adhere to
the fiber.
ADJECTIVE dyes do. the mordants join with the fiber and the dye
to set the colour permanently. it enters deeply into the fiber and when
the dye is added, they combine to form a color.

Chemicals used in turmeric dyeing
Turmeric dye, Harda, Behera, Banana pseudo stem sap,
potassium permanganate (KMnO4)

Dyeing with turmeric (methods)

first off all, Natural turmeric were washed with water and dried.
then crushed into coarse powder form for extraction. in order
to determine the optimum extraction conditions.
1. A set of sample of crushed turmeric powder, dissolved in
distilled water with a liquor ratio 20:1 and subjected to stirring
at room temperature  for 10 minutes.
2. A set of samples soaked in water and then subjected to stirring
at boil for 30 minutes.
Dyeing were carried out at 60 degree c, with 20:1 liquor to goods ratio
for 60 minutes.

Cotton dyeing with termeric

(Mordanting)

here, 4 mordants are used such as, Harda, Banana pseudo stem sap,
potassium parmanganate ( KMnO4).
mordanting carried out through three way
1. pre-mordanting
2. simultaneous mordanting and dyeing
3. post mordanting

pre-mordanting with Harda

Cotton dyeing with turmeric

The fabric was treated with a mordant concentration of 5%, 6%,

7%, 8%, 9%, and 10% on weight of fabric at 60C for 30 minutes
the material to liquor ratio use for mordanting was 1:20.
after the mordant material was dyed at 80C for 60 minutes.

pre-mordanting with Behera, Banana pseudo stem sap and potassium

permanganate

carried out in a similar manner as Harda

Simultaneous mordanting and dyeing with Harda

The fabric was treated with a mordant concentration of  5% to
10% on weight of fabric at the same dyeing bath at 80C for 60
minutes. the material to liquor ratio  for dyeing will be 1:20.

Simultaneous mordanting and dyeing with Behera,Banana pseudo stem

sap and potassium permanganate

carried out in a similar manner as Harda…….

post-mordanting with harda

The dyed fabric was treated with mordant at 60C at concentration
5%…to…10% for 60 minutes with M:L 1:20.

Post-mordanting with Behera, Banana pseudo stem sap and

potassium permanganate

Carried out in a similar manner as harda

4.           crock meter                                                              Rubbing fastness

Testing and Analysis of cotton dyeing with turmeric

1. K/S value of dyed sample with CCM
2. washing fastness recommended in ISO 3 methods
3. Rubbing fastness : recommended in ISO 105.
4. Light fastness ( ISO 105-A02:1993)
5. COD.

Limitation of natural dyeing :

1. Lesser availability.
2. Poor colour yield.
3. Complexity of dyeing process.
4. Non reproducibility of shade.
