Taking Care of your Bullet Proof Vests for Sale


Bulletproof vests for sale are made from different types of materials, such as strongly woven or laminated fabric and composites. While there are vests of differing types based on threat levels the wearer faces, it is vital that the vest be cared for properly for maximum performance and personal safety. According to the National Institute of Justice, maintenance and care of a vest plays a larger role in the life of the garment than age. Follow the manufacturer's recommendations for cleaning. Frequent hand-cleaning of the vest should be carried out by the owner

Here are some of the ways to take care of your bullet proof vests.

1.   Remove the trauma plates and armor inside the panels. Handle the armor carefully, as it is brittle. Inspect it for cracks.
2.     Wet the sponge with cold water and apply a few drops of mild detergent to the sponge. Clean the vest and the vest's protective carrier by wiping all surface areas. Some stubborn stains require the use of a soft-bristle brush.
3.     Rinse the sponge until all soap is removed. Soak the sponge with cold water and thoroughly remove all soap from the vest and carrier. The National Institute of Justice indicates soap residue absorbs water, reducing the efficacy of some fabrics.
4.     Inspect the garment for signs of wear, such as the seams and areas of the fabric that have rubbed on an object. Look for tears and holes. Replace a vest that shows signs of wear.
5.       Lay the vest and carrier flat to dry in a well-ventilated, shaded area indoors. Once drying is complete, return the trauma plates and armor to the vest.
6.      Lay the vest and carrier flat to dry in a well-ventilated, shaded area indoors. Once drying is complete, return the trauma plates and armor to the vest.

How to Store Bullet Proof Vests for Sale


Bulletproof vests are used by law enforcement officers to protect against firearm fired projectiles. The bullet proof vests for sale need to be stored correctly to avoid shoulder strap stretching, moisture retention and bunching of the bottom of the vest. Improperly stored vests can become uncomfortable and unsafe. Your warranty may be voided if you do not follow the company's proper care instructions. Clean and store your vest correctly so it will stay effective for several years.

Here are some of the tips and guidelines to store your bullet proof vests.

1.      Remove any trauma or hard plates from the front or rear of the vest. Trauma plates protect you from blunt trauma injury in a local area, such as the torso's mass center. Plates being close together cause extra moisture retention due to a lack of airflow.
2.     Clean your bulletproof vest as soon as you can after wearing it. Lightly use a soft bristle brush to scrub off any debris. Sponge the surfaces of the vest using warm water and a mild liquid detergent. Dry it with a soft cloth. Never store the bulletproof vest while it's still damp. Moisture retention from a damp vest can lead to mold growth.
3.      Store your bulletproof vest laid flat in a well-ventilated place. This prevents bunching of the bottom of the vest. It also stops wrinkles and sets in the material from forming. Avoid standing the vest up in a closet or locker because the bottom of the vest will bunch up over time. Avoid storing the vest on a hanger because it stretches the straps and retains moisture.
4.   Check your bulletproof vest after use for any damage. Never wear a damaged vest. Contact the manufacturer for repair options.
5.       Never lay out your vest in direct sunlight. The UV rays can cause material deterioration.

These tips should also be applied to police body armor and tactical body armor.

How do Bullet Proof Vests for Sale Work?


Bullet proof vests for sale is a type of personal body armor designed to protect a human being from damage incurred by projectiles such as bullets and shrapnel, and sometimes stabbing weapons such as knives. Bulletproof vests typically cover the chest and abdomen, leaving the arms, head and areas below the waist exposed, although other protective gear can be used to cover these areas. The two basic types of bulletproof vests, soft and hard, work in different ways.

Soft bulletproof vests are made of tightly woven, flexible synthetic fibers such as Kevlar, which enable the wearer to move normally. The way a soft bulletproof vest works is essentially the same as a net; the fibers of the vest are very strong and woven together so closely that the material catches the bullet and quickly spreads out the impact force along the surface of the material. As the impact force spreads, the bullet's penetrating force become inadequate to pierce the powerful mesh; essentially, the vest catches the bullet. Soft bulletproof vests are common among law enforcement officers who require flexibility, mobility and basic protection. Soft bulletproof vests are usually effective against the types of small-caliber handguns and bullets that police officers are likely to encounter, yet they may be ineffective at stopping bullets fired from more powerful guns and rifles.

Rigid body armor vests operate much like armor used in ancient and medieval times. Rather than catching the bullet, hard armor vests use rigid materials, such as super-hard ceramic tiles, to deflect bullets away from the body. Rigid bulletproof vests usually offer better protection than soft armor, but are heavier and less flexible, making them impractical in certain environments. Rigid armor can also offer good protection against stabbing weapons. With both flexible and rigid armors, blunt force trauma can be a concern even if bullets do not penetrate the skin. The impact force is likely to cause severe bruising and can still potentially cause life-threatening internal injuries.

There are different bulletproof vest material that is being used by soft bullet proof vests and rigid bullet proof vests.

Staying Cool Wearing Bullet Proof Vests for Sale


Bullet proof vests for sale can be made out of several different materials. Some vests are composed of steel plates that are connected together inside of a thick fabric, while other, lighter-weight vests are made of a ballistic fabric that is then sewn into a cotton or nylon covering. Bulletproof vests often retain heat due to their weight and density, and wearing them can therefore be uncomfortable. Staying cool while wearing a bulletproof vest requires some diligence especially if you have a higher rating of vests. The higher the rating of the vests, the higher the protection it gives but coupled with that, is the lesser comfort you will get.

So how do you stay cool? Here are some tips and guidelines for you.

1.    Wear a cooling t-shirt between the shirt and the vest. Cooling shirts are designed to create a bit of air between the skin and the vest, while also removing moisture from the skin by pulling it into the fabric, allowing air to then cool the skin.
2.    Utilize the air conditioner in any vehicles or buildings you are in when wearing a bulletproof vest, to minimize sweat and keep yourself cool.
3.    Attach a plastic hose to your car air conditioner and then stick the other end down the vest to cool yourself during break periods. Companies make hoses like this specifically for that purpose.
4.    Avoid wearing added layers of clothing like jackets if you can avoid it. The more clothing you wear over the vest, the more your body heat will be trapped around the vest and the hotter you will feel.
5.       Drink plenty of water to keep yourself hydrated. The cold water will also help you cool down.

According to the National Institute of Justice, comfort and the inability to move easily are the primary complaints of our soldiers wearing body armor clothes. This is why manufacturers are advised to always consider these two factors when manufacturing body armor.

Manufacturing Process of Bullet Proof Vests for Sale


Some bullet proof vests forsale are custom-made to meet the customer's protection needs or size. Most, however, meet standard protection regulations, have standard clothing industry sizes (such as 38 long, 32 short), and are sold in quantity.

To make Kevlar, the polymer poly-para-phenylene terephthalamide must first be produced in the laboratory. This 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.

Unlike Kevlar, the Spectra used in bulletproof vests is usually not woven. Instead, the strong polyethylene polymer filaments are spun into fibers that are then laid parallel to each other. Resin is used to coat 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. The vest shape can then be cut from the material.

Kevlar has long been the most widely used material in bulletproof vests. To make Kevlar, the polymer solution is first produced. The resulting liquid is then extruded from a spinneret, cooled with water, stretched on rollers, and wound into cloth.

A recent competitor to Kevlar is Spectra Shield. Unlike Kevlar, Spectra Shield is not woven but rather spun into fibers that are then laid parallel to each other. The fibers are coated with resin and layered to form the cloth.

As many layers of the material as needed (as few as eight layers, or as many as 25, depending on the level of protection desired) are laid out on the cutting table.

This is the shortcut description of the manufacturing process of bullet proof vests. Added information is that there are types of body armor – type I, type iia, type iiia body armor, type iii and type iv body armor.
