How is Bulletproof Jacket manufactured?

 Bulletproof Jacket help soldiers to be prevented from being injured by knife, bullet, bomb blast etc. These Bulletproof material were made up of ballistic nylon material till 1970s but now the formula changed and a new material named poly-parpheny lenetere phthalamide was invented with a brand name KELVAR. This liquid polymer get into the jacket and woven into them.
