Protective clothing is an essential component of the armed forces. They need to adorn themselves with all possible armors. The list Includes weapons and personal protective equipment. Out of the whole list, stab-proof vest deserves special mention. It is generally worn over the uniform or any customized clothing it functions as a shield to resist the attack to chest band back. Right from the name, it is evident that it serves protection against knives, needle or slashes. However, the stab vest differs from the bulletproof jacket. To some extent, depending on the calibration of the bullet protection is prevailed by a stab vest. It is mostly used to protect against firearms.
LEGALISATION OF THE STAB VEST:
Stab vest is generally legalized when used with the permits of police in charge. However, if working in any secret mission, wearing under your clothing works as the best defense. The police administration needs to be understandable with the use. Wearing stab-proof underneath the clothing increase defense level up against spikes or stab attacks. It functions on its ground without coming in the vision of opponents.
WORKING EFFICIENCY OF STAB VEST:
Various tests prove the efficiency of the stab vest. The resistance power of the jacket from sharp objects is proved. It is efficient in wearing against stabbing attacks of knives or broken bottle. The highlights of the jacket are it allows penetration of the object to a safe distance so that it does not puncture any body parts. It is made up of a typical material called Kevlar.
MICROSCOPIC DETAILS ABOUT KEVLAR AND ITS WORKING MECHANISM:
Kevlar, characterized by light weighted polyacrylamide plastic fabric. The plastic content provides excellent flexibility to it by increasing the tensile strength. The single unit of the Kevlar looks highly coiled. The onset of polymerization leads to massive tangling of the Kevlar monomers creating resistance in stretching. The stab vest slightly differs in the mechanism from the bulletproof jacket. The later comprise of the usage of the same material but works in a more précised manner.
When a bullet penetrates the bulletproof jacket, it works against the layers of the fabric. However, the tensile strength of the material works as opposed to the ball, thereby resisting further penetration. The Kevlar fibers absorb most of the energy of the bullet, thus protecting the subject from getting shot.
The stab vest is a significant creation of scientist in the defense field. They are generally comprised of steel mesh, unlike chainmail. It increases the difficulty level of the penetration game of knife. However, stab vest does not play a fair game in case of a bullet. Decreased calibration of the shell provides the advantage of gushing inside the jacket, ultimately inside the flesh of the subject. The stab jackets are designs to provide protection specifically against knives or ant pricky stabbing materials. The local police widely use it during raids. However, in secret missions, the stab vest is designed more intricately so that it works as both stab and bulletproof.
