3.  c
 Nowadays safety and protective textile have become
an integral part in one or other form. Safety and
protective textile refer to garment and other fabric
related items designed to protect the wearer from
harsh environmental effects that may result in injury or
death.

5.  c
 Industrial textile is used to protect from one or more of following :-
 Extreme heat and fire .
 Harmful chemicals and gases .
 Bacterial environment .
 Electric hazards .
 Radiation .

9. Defence textiles

10.  Pre Twentieth century
Normally heavy & uncomfortable uniform for wear.
Produced from natural fibers or heavy metal is used.
Uncomfortable for soldiers.
Twentieth Century
Light weight & durable,
many high performance
fibers came into usage.

11. Pre Twentieth century

12. • Earlier silk & metal was used.
• But now high Performance fibres are used like
• Kevlar - Polyphenylene terephthalamide, 5 times stronger
than steel. Properties like tensile strength at low
weight, low elongation at break, high modulus
high chemical resistance etc.
• Dyneema – polyethylene, 10-100 times stronger than steel. Properties like
very high strength to weight ratio & light enough to float on
water.
• Twaron - para-aramid, 5 times stronger than steel.

13. • Spectra - polyethylene fibers.10-100 times stronger than steel,
high strength.
• Spider silk – protein, 25 times stronger than steel

30.  Gearing towards an integrated future
 The general aims of future systems are:
 Improve protection against natural and battlefield threats
 Maintain thermo-physiological comfort or survival in extreme conditions
 Improve compatibility between and within different clothing components
 Reduce weight and bulk of materials
 Integrate functionality so that fewer layers provide multi layer protection
 Reduce life cycle costs by making systems more effective, durable, and
recyclable and by buying few components in the system
