3. What is a Nano Particle ?
 The prefix Nano comes
from the Greeks word
'Nanos' which means
dwarf(extremly small).
 It may say that billionth
of the unit.
 Nanoparticle are
between 1 to 1000nm
in size (1nm= 10-9m).
 Ultrafine particle are
sized 100 to 2500nm.

4. Different Structures of Nanoparticles
There are three types
of structure of
nanopartiles
 Whiskers
 Hooks
 Spine

5. Properties of Nanoparticles
Dramatic Change in Properties When particle size
changed to Nanometer.
 Normal Ceramic Particle Britle
 Nano Ceramic Particle Deformable,Flexible
 Normal Gold Yellow
 Nano Gold Red

6. Nano-Technology
 Nanotechnology
is an act of
purposefully
manipulating
matter at atomic
scale or
nanosclae.
Deals with 0.2
nm to 100 nm.

7. Types of Nano-Technology in Textile
Three are three types of nanotechnology
used in textiles.
Nanotechnology in febrics and
yarns(fabrics)
Nanotechnology in coating(Textile
Finishing)
E-Textiles

8. Applications of Nanoparticles in textile

9. Some Impotant Nano-Particles Used
in Textile
 Silver Nanoparticles (anti bacterial finishing)
 Fe Nanoparticles (remote heating, conductive magnetic)
 ZnO and TiO2 (UV protection, fiber protection, oxidative catalysis)
 TiO2 and MgO (Chemical and biological protective performance, provide
self-sterilizing function)
 SiO2 or Al2O3 (Super water repellent finishing)
 Indium-tin oxide (IR/EM protective clothing)
 Ceramic Nanoparticles (Increasing resistance to abrasion)
 Carbon black Nanoparticle ( Increasing resistance to abrasion, chemical
resistance and impart electrical conductivity, coloration of some textiles)
 Clay nanoparticles (High electrical, heat and chemical resistance)
 Cellulose Nano-whiskers (Wrinkle resistance, stain resistance, and water
repellent)

10. Nano Fibers
 A continuous fiber
which has a diameter
in the range of
billionth of meter.
 The smallest Nano
fibers made up now a
days are b/w 1.5 nm
to 1.75 nm
 Produced by
Electrospinning.
Nanofibers

11. Value Addition of Nano Whriskers
Oil repellency
Breathable
Fabrics remains
soft and natural
Wrinkle resistance
Durability

12. Value addition due to Nano Wrap
Strength &
Durability
Improvement in
Colour Fatness
Crease Retention
Static Resistance

13. Wrapped Fabrics

14. Water Repellent & Self Cleaning
Fabrics
Fabrics coated with
Nanoparticles of
SiO2 and Al2O3
are strongly water
repellent and due
to coating of
nanoparticles dust
particles also
swaped.

15. Nano-Fabrics in Military Uniform
Military uniform that change their colour to
match the envoirnment
Light weight bullet-proof vests
Wound controlling army trousers to control
excess bleeding
To detect location
