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. University of Agriculture Faisalabad – uaf

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, University of Agriculture Faisalabad – uaf

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. University of Agriculture Faisalabad – uaf

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 . University of Agriculture Faisalabad – uaf
