• Application of Supercritical Fluid (SCF) for Dyeing.
Increasing consideration of ecologic consequences of industrial processes as well as legislation enforcing the avoidance of environmental problems have caused a reorientation of thinking and promoted research for replacement of conventional technologies. During the last three decades, supercritical fluids, which are characterized by exceptional physical-chemical properties, have been used in extraction processes. 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
• Development of pet/ nanoclay nanocomposite for barrier packaging.
Packaging of any product is always an integral part of product and serves various purposes. Keeping the contents clean, fresh, and safe for the intended shelf life is a primary function of any packaging. Packaging of food products, medicines and agrochemicals that have poor shelf life are required to be insulated from external environment. The incorporation of nanoclay in polymeric matrix is known to improve the barrier resistance, thermal resistance and puncture resistance of polymeric matrix. Hence it is envisaged to experiment with the development of PET/ Nanoclay nanocomposite for packaging and explore the suitability of their application.
• 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. Therefore, the optimized nanoclay particle size, particle size distribution, and the uniform dispersion of nanoclay inside the polypropylene matrix are very critical for the dyeing properties of the dyeable polypropylene nanocomposite
• Evaluating compatibility & establishing methodology for simultaneous functional finishes for textile.
Various anti-microbial, anti-fungal and anti-viral 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 rayon fibre. Thus developed fibre would find applications in healthcare textiles, home furnishing, shoe lining fabrics and innerwear
• Development of reflective Agrotextiles for Sun management.
Many crops are also extremely light sensitive. Sunlight management is the process of manipulating the sunlight quality and quantity to which plants are exposed. A new generation of agrotextiles can be developed to address this problem. They would allow the grower to choose both the duration of light as well as the particular wavelength that will produce the desired effect from the plants at all stages of development. The proposed project aims to develop wide range of agrotextile screens which will reflect light and thus ripen all plants uniformly protecting them from extreme climatic conditions. It is proposed to develop woven reflective agro ground covers with suitable reflective coatings leading to desired results.
• Design of processing sequence suitable for embroidered fabrics incorporating embellishments.
The project envisages studying the different type of embellishments used during embroidery and the problems being encountered during their processing. It is proposed to find out remedial actions to counteract these problems and suggest a standardized processing sequence for these embroidered fabrics.
.
• Standardisation of Norms for Agricultural Shade Net.
.
The project envisages studying the different agrotextile shade nets being manufactured and used in the country for benefits in agriculture yield improvement. Although the products are gaining popularity in the country at the manufacturers' end and users' end, there is no clear guideline available defining the norms for the manufacture and construction of the product. So also, the methodology to test the functional properties of these products has not been established. The proposal is aimed towards establishing these norms for agricultural shade nets.

• Development
of Durable, Breathable and Barrier Work wear Fabrics
for Agrotextile Applications |
Work wear fabrics can be identified as those fabrics
that are worn by the workmen during the course of performing
their duties. The work wear fabrics used by the agro
workers in the country are not scientifically designed.
They do not address the functional as well as comfort
requirements of the farmers. Hence it is desirous to
develop workwear fabrics that are impervious to the chemical
fluids being handled by the farmers and at the same time
comfortable to the wearer and durable in nature. The
proposed work focuses on development of such comfortable,
durable, work wear fabrics for agrotextile application
by using plasma technology. |
• Development
of Speciality Fabric for Water conservation and Soil
Erosion Control used in Horticulture Application |
Controlling the environments offers crop protection
for specific target, and quality maintenance by elimination
of the variations and hazards associated with the weather.
It is possible to control temperature and humidity with
varying degree of precision, avoid damage from wind and
rain and regulate nutrients level to meet plants requirement
by using green/ polyhouse techniques. Textile structures
can play a crucial role towards achieving this goal.
Keeping in view this requirements the present project
is proposed to develop a two layered fabric made up of
scrim stabilized uniform fibrous web adhered to mono
porous membrane. |
• Indigenous
Development of Ultrasonic Device(S) for Maintenance
of Weaving Accessories |
Lack of cleaning of weaving accessories and spares
result in loss of production and deterioration of fabric
quality. Ultrasonic waves have been popularly used for
cleaning in general. The same technology is proposed
to be deployed for maintenance of weaving spares and
accessories. The present project envisages cleaning the
spare parts in weaving machinery viz., healds, reeds,
leno doups and such spares using the new ultrasonictechnology.
The efficiency of ultrasonic cleaning in other fields
is well established. A device(s) will be designed to
efficiently clean the spares which will be faster and
also worker friendly. |
• Manufacturing of woven geotextiles for ground improvement using vertical drain technique |
Development of suitable geotextile for ground improvement
is envisaged in present project. This technique will
be helpful to retrieve marshy land for constructional
purposes. Various tubular structures with varying diameters
will be prepared from synthetic materials. These will
be used as vertical drain along with a backing fabric.
The behaviour of soil settlement will be assessed in
laboratory by using different simulated soil strata along
with controlled variables. |
• Low
cost Upgradation of first generation imported shuttless
looms and indigenous shuttles looms for decentralised
sector |
It is proposed to develop a few simple mechanisms,
which can be retrofitted on these and will be synchronised
with the basic functioning of the machine, thereby, enhancing
the potential to reduce fabric defect and increase productivity.
This will result into cost reduction and better profitability
as well as versatility of the machine eliminating its
limitations. |
• Developing
fabrics with thermoregulatory properties using phase
change materials (PCM) for specialty application |
Fabrics with thermo-regulatory characteristics are
in demand for the sportswear, defence personnel, mountaineers
and the staff in the healthcare sector. This project
aims to identify and develop thermo-regulatory behaviour
fabrics suitable to these fields of application. Development
of such value-added textile products for specialized
uses would open a new avenue in market for textile products,
thereby benefiting the industry. |

• Design & Development
of Creep Testing Apparatus for Geotextile |
The geotextile structures are required to perform reinforcement
and stabilisation functions in conjunction with the soil
with their properties unaltered throughout their service
life spanning over a few decades. These geotextile like
any textile material are prone to accumulative stain
on continuous loading, i.e. creep, which may alter the
properties of geotextiles in use. Hence, it is important
to evaluate the creep behaviour of geotextile. The project
aims to develop a dedicated creep tester for geotextiles. |
• Design
and Development of Clamping devices for testing tensile
properties of High strength Technical textile fabrics |
With the growing demand of technical textiles globally
its testing is also gaining importance. As conventional
methods of testing have some limitations with the high
performance fabrics, the objective of the project is
to develop suitable grips for better gripping of high
performance textiles during tensile testing by wide width
method by hydraulic grips. |
