of nonwoven fibre mats with use of
Super Absorbent Polymers (SAP) so
as to support horticulture cultivation.
Identification of various fibre substrates
and their structure suitable for fibre mats
has been done. Procurement and study
of super absorbent polymers suitable for
the horticulture is under progress.
5. Establishing correlation on UV
Stability of Technical Textiles under
different exposure conditions
Keeping the material for testing as
constant, a correlation would be arrived at
for degrading the sample to same level of
strength loss under different conditions of
exposure using different exposure media
viz., xenon, UV-A or UV-B.
Identification of technical textile samples
for evaluation of weathering and Study
of the microelements of the fabrics with
respect to its characteristic UV stability and
other chemical degradation is ongoing.
6. Application of Supercritical Fluid
(SCF) for Dyeing
The present project envisages application
of supercritical fluids as reaction medium
and as a solvent medium in textile chemical
processing for dyeing. Carbon dioxide is
the most investigated and would be used
as supercritical fluid as a dyeing media. It is
a naturally occurring fluid that is chemically
inert, physiologically compatible, and
relatively inexpensive and is readily
available for industrial consumption.
Dissolution behaviour of many different
classes of dyes has been studied. The
supercritical dyed samples are being
evaluated vis-à-vis conventional dyed fabric.
7. Dyeing of Polypropylene using
Nanotechnology
The proposed project aims to produce
dyeable polypropylene that can be made
using nanoclay infusion technique. The
dye sites created in polypropylene were
the prospective areas where nanoclay
is located. The polypropylene pellets
and nanoclays have been identified
and procured. Modified polypropylene
+ nanoclay pellets are prepared and the
process is been optimized. Dyeing of
various modified polypropylene in film
form has been completed. Spinning of
fibres from modified PP + nanoclay is
being carried out.
8. Evaluating compatibility & establishing
methodology for simultaneous
functional finishes for textile
Various anti-microbial, anti-fungal and antiviral
treatments have been formulated for
different natural and regenerated fibres.
However, each has their limitation in the
form of their compatibility with each other
and their durability throughout the life of the
garment. The project envisages to develop
a combination of such finishes of permanent
nature in situ in the textile fibre. Thus
developed fibre would find applications in
healthcare textiles, home furnishing, shoe
lining fabrics and innerwear.
Different auxiliaries for application as anti
microbial, anti fungal and anti viral finishes
have been identified and procured. The
substrate for application of finishes
has been studied and cotton and nylon
have been identified for application.
Application of antibacterial and anti
fungal application on cotton and polyester
as well as combination application of
these two finishes simultaneously has
been completed and are being tested for
their efficacy.
9. Design of processing sequence
suitable for embroidered fabrics
incorporating embellishments
A clear processing guideline is not
available to the processors for handling
