What Is A Bulletproof Vest, And How Are Different Materials Used For Making The Panel Cloth?

Bulletproof vests are modern light armor designed to protect the wearer's vital organs from injury caused by firearm projectiles.




Making the Panel Cloth for the Bulletproof Vest:

  1. To make Kevlar, the polymer poly-para-phenylene terephthalate must first be produced in the laboratory. It is done through a process known as polymerization, which involves combining molecules into long chains. The resultant crystalline liquid with polymers in the shape of rods is then extruded through a spinneret (a small metal plate full of tiny holes that looks like a shower head) to form Kevlar yarn. The Kevlar fiber then passes through a cooling bath to help it harden. Finally, the synthetic fiber is wound onto rolls after being sprayed with water.

  2. Unlike Kevlar, the Spectra used in military bulletproof vests is usually not woven. Instead, the strong polyethylene polymer filaments are spun into fibers that are then laid parallel. Next, resin coats the fibers, sealing them together to form a sheet of Spectra cloth. Two sheets of this cloth are then placed at right angles to one another and again bonded, forming a nonwoven fabric that is next sandwiched between two sheets of polyethylene film


Military Bulletproof vests are widely used by soldiers, law enforcement, and security personnel. A tactical vest is a heavy-duty vest that can wear over regular clothing. It protects the body's vital organs and gives a way to carry gear when on assignment.
