Project Title: “DEVELOPMENT OF FIRE RETARDANT JUTE FABRIC”
(JTM R&D PROJECT NO.:- 10)
1.0 Objectives:
·
Identification and development of suitable methods of producing
fire retardant jute based fabrics either by blending jute with
fire retardant fibres and/or by imparting suitable fire retardant
chemical finishes;
·
Optimisation of suitable chemical formulations for production of
non-durable and durable (wash-fast) flame retardant finish of jute
based fabrics;
·
Determination of the flame retardancy and other thermal
characteristics of blended and/or chemically finished
fire-retardant jute fabrics, for end use performance as per
existing National & International standards;
·
Standardization of cost viable fire retardant formulations for
imparting semi-durable and durable fire retardant finishes to
jute-based fabrics:
·
Training of manpower (students, industry personnel and
researchers) in this field;
·
Bulk
trial and technology transfer in industry to develop usable
products from such fire-retardant finished jute fabrics and their
required testing methods and standardisation.
2.0
Deliverables:
·
Development of newer technology/ formulation for non-durable (leachable),
semi- durable and durable fire retardant finishes(two such
formulations for each type) for jute based materials
·
At
least two formulations of durable fire retardant finish on jute
based materials with the functional properties targeted as
follows:
|
Test parameters |
Target parameters
as per terms of reference of JTM-R&D-JMDC Project No. 10 |
|
LOI value |
40-45 |
|
Char-length (cm) |
Between 1-2 cm
|
|
Flame spread time |
Maximum flame
spread time be 100 seconds for burning 2 cm |
|
Burning time |
Preferably no
burning or burning of 1-2cm should take at least 60 seconds
or more. |
|
Afterglow time |
Preferably no
afterglow or afterglow below 5 seconds . |
·
Bulk trial, dissemination and transfer of technology for the
processes and technology developed (in one or two units) and
publications of research papers/technical manuals and manpower
training and demonstration of testing methods for
fire-retardant
finished jute products.
3.0 Achievements so far:
Following are the different fire-retardant formulation that have
been tried
· Borax-boric
acid
· Urea
and Ortho-Phosphoric Acid,
· Tetra
sodium Pyrophosphate,
· Sodium
Per-borate etc.
· Following
are some improved fire retardant formulations using Nitrogen
and Phosphorous Compounds in combination (to get N-P
Synergy),
· Urea plus Di ammonium Phosphate (DAP),
· Thio-urea plus DAP and
· Dicyandiamide plus DAP
· For development of some wash fast system of eco-friendly
fire-retardant treatment, i R&D trial have been done with
· Phosphorylation of polyols (PVA/PEG etc) and their subsequent
application on jute fabric.
· Another one new improved fire retardant formulations using
Nitrogen-Sulfur based fire retardants in combination (to get N-S
Synergy), using
· Ammonium sulfamate/ sulfamic acid with urea or other nitrogen
compound has been initiated
· FTIR study is in progress for the all the formulations optimized
in the 1st and 2nd year of the projects to
understand the nature of chemical reactions of FR-chemicals with
jute.
·
A bulk scale trial was arranged on 28th and 29th
May 2011 in order to evaluate/ try out the laboratory recipes /
findings in actual mill conditions and subsequently to rectify /
optimise
for achieving the targeted Finish.
