Project Title: “Standardization of Application of Natural Dyes on
Jute based Textile for Eco-friendly Jute Decorative and
Diversified Products”
(JTM R&D Project no. 17)
1.0 Objectives:
-
Identification of suitable natural dyes for dyeing of jute based
products;
-
Standardisation of methodologies of application of natural dyes on
jute substrate to develop newer shades with acceptable fastness;
-
Pre-treatments and post treatments of jute to improve the dye
ability and colour fastness;
-
Compatibility of different pairs of natural dyes to be applied in
mixtures;
-
Training of manpower on developed standard methods for application
of natural dyes on jute materials
-
To popularize use of eco-friendly natural dyes for jute
diversified products.
2.0
Deliverables:
-
Standardisation of the processes for natural dyes from source
origin (10 dyes) and production of different combined shades (90
shades).
-
Process standardisation and production of different combined
shades from purified natural dyes procured from different
companies (2 companies X 10 days X 9 shades each).
-
Bulk scale implementation/ field trial (maximum two) of the
natural dyeing technology developed for Jute based materials, in
jute mills or in small scale / cottage jute dyers and process
houses in association with AJHEEI/IJMA.
-
Dissemination of project outputs and Transfer of Technology for
natural dyeing processes through Manpower or hands-on
training/seminar/workshop/preparation of shade cards and
publications of research papers/technical manuals (one) and
preparation of shade card (100 shades) and cost analysis.
3.0 Achivements so far:
-
Optimization
for extraction of Tesu (Palash flower), Manjistha (Indian
Madder), Red Sandal wood and Jack Fruit Wood, Catechu,
Pomegranate rind and Babool are completed & 63 different shades
are developed..
-
Identified
suitable eco-friendly mordants for jute, like aluminium sulphate,
ferrous sulphate and myrobolan etc. It is observed that a double
mordanting system with 20% Harda followed by 20% Al2(SO4)3
premordanting is best suited for jute to be dyed with natural
dyes.
-
R & D work on
optimization of dyeing process variables has been completed for
seven source natural dyes, e.g., Red sandal wood, Jackfruit
wood, Manjistha and Tesu, Catechu, Pomegranate rind and Babool
for its subsequent application on differently mordanted and
chemically pretreated jute fabrics.
-
Total 126
shades of different colours have been developed for natural dyes
obtained from M/s Alps Industries Ltd & M/s Sir Bio-Tech
Industries Ltd.,.
-
Technical
Booklet and Shade card is under process .
-
Bulk Trial at
Two Different places ( Asim Kar & Industries & Reliance Jute
Mills)
-
Industrial
Liaison work, dissemination and Meetings with AJHEEI
representative were held time to time at IJT.
