The document discusses bulletproof jackets, including their history, manufacturing process, and uses. Bulletproof jackets were first developed in the 1820s using silk but modern ones often use Kevlar fabric invented in the 1970s. They are manufactured by layering and sewing Kevlar fabric panels into a carrier vest. When struck by a bullet, the strong Kevlar fibers absorb and disperse the impact energy to prevent penetration. Bulletproof jackets are worn for protection by the military, police, and others at risk from small arms fire.

It Helps to absorb the impact and reduce penetration to the body from fired
projectiles and save from explosions.

4. THE HISTORY OF BULLETPROOF CLOTHING:
In the 1820s softer silk body armors were developed by the Japanese.
These armors were effective but more expensive
in the early 1970s, The DuPont’s Kevlar ballistic fabric was invented . Its
strength is very high.

6. THE BODY ARMOR INDUSTRY:
Moreover, growing focus on wars is boosting up the requirements of
bulletproof clothing globally. •
Some of the major brand names working in this industry are Runner,
Garrison Bespoke, Aspetto, and BulletSafe. •
In the US alone, the bulletproof body armor manufacturing industry can
be valued at $465 million a year, as per a Market Research report
according to a Grandview’s 2016 research,

7. RAW MATERIAL OF BULLETPROOF JACKETS
Bulletproof clothing is made using fibers or filaments that are both lightweight
and strong.
Kevlar® is the most widely used option, where a solid thread is spun out of a
liquid chemical blend.
• Another option for raw material in bulletproof clothing is Dyneema®, which
is a made by a gel-spinning process from a polythene base, providing
incredible strength and softness to the material.
• These fibers/filaments are then converted into yarns and sheet materials for
usage in final clothing.

8. DUPONT’S KEVLAR BALLISTIC FABRIC
Kevlar is basically a type of plastic with extremely high tensile strength,
owing to the tightly bound, parallel molecules, that makes the fabric
bulletproof.
• Kevlar fabric shows the property of absorbing and distributing the
energy that comes in contact with it.
• Thus, Kevlar can effectively catch and prevent the bullet from
penetrating through the wearer’s body.

9. MANUFACTURING PROCESS
The bulletproof panels are made of multiple layers of this ballistic material, and the
required thickness is determined based on the level of protection that has to achieve
from the garment.
Multiple layers of this ballistic fabric are cut and sewn together to provide the
required protection to the wearer.
These layers of sewn ballistic material are then put into a protective envelope, which
is heat sealed to ensure the protection of these layers from humidity and water.
The ballistic panels are fitted into carriers, which have pockets to insert the panels .
This carrier along with the ballistic panels together constitutes bulletproof clothing.

11. WORKING
When a bullet strikes body armor, it is caught in a “web” of very strong
fibers.
These fibers absorb and disperse the impact energy that is transmitted to
the bullet proof vest from the bullet, causing the bullet to deform.

12. USES OF BULLETPROOF JACKETS :
Bulletproof clothing is actually knife resistant clothing, but can help the
wearer even in vehicle accidents.
a bulletproof vest is not truly bulletproof, it is actually just bullet resistant.
It can prevent the certain type, sizes and speeds of bullets penetrating the body,
but even when the bullet is stopped, the impact can injure the wearer.
Bulletproof body armor is designed only to protect the wearer from small
caliber weapons.
