The history of  Goodyear welt

Before the Industrial revolution, shoemaking craftsmen needed to use awls to taper holes and then sew the welts by hand, which is the hand welt process. In 1871, after the start of the second industrial revolution, a patent called "Goodyear Shoemaking Technology" was approved by the United States Patent Office. A brand-new sewing machine was invented that could replace manual work to remove soles and sew inner threads. The inventor was Charles Goodyear. Mr. Goodyear was an American inventor, known as the "Father of Rubber" for his invention of vulcanized rubber.

The process of the Goodyear welt

The process of the Goodyear welt is as follows: Firstly, paste a layer of canvas strips on the insole, so as to form a rib structure similar to manual slotting. And then use a machine to complete the sewing of the welt,upper and insole. It is worth noting that the Goodyear shoe machine only sews inner threads and has nothing to do with outer threads. As early as 1856, Lyman Reed Blake had invented the Rapid stitch machine, a machine that could sew outer stitches (Lyman Reed Blake was also the inventor of the Blake process). The emergence of the Goodyear shoe machine has greatly improved the production efficiency of shoes. Together with the upper sewing machine and the rapid stitch outer thread sewing machine, the shoemaking industry has been brought into the machine age, liberating manpower.

Now, we can draw a clear conclusion that the Goodyear welt is used to replace Hand welt, and it has been tied to the machine since its birth. Shoes with welts sewn by craftsmen can only be called “hand welt” , not Goodyear welt.

In movies and video games, body armor makes you invulnerable, able to survive many shots without even slowing down. In real life, of course, things are much different: Body armor doesn’t repel bullets. Being shot — even with armor on — is a traumatic experience at best. When a bullet hits body armor, the tough layered fibers that make up the armor decelerate the bullet and spread out its force. The bullet’s effect on the armor, and the tissue beneath it, is still considerable, and can cause tearing of the skin, bruising, and even broken bones.

We- China Xinxing Guangzhou Imp&Exp Co., Ltd.  will introduce how to test the body armor.

However, the amount of deformation must fall within certain limits or the armor will fail to live up to the standards co-authored by the National Institute of Standards and Technology (NIST) and the National Institute of Justice (NIJ). The standards were developed with input from a wide variety of stakeholders and published by the NIJ. These standards require that the armor be tested by mounting it onto a block of clay with specific, well-understood properties. Researchers use clay that is only deformed by a specific amount when a 63.5 mm (2.5 inch) diameter steel sphere is dropped onto it from a height of 2 meters (6.56 feet). When the armor is tested, it must withstand 12 shots, six front and six back, and the deformations in the clay block behind it may be no deeper than 44 mm (1.73 inches). 

Research at NIST has found that moisture from sweating, along with the folds that occur in the vests’ fibers from the officers wearing the armor, can cause certain types of fibers to weaken and fail. As a result, part of the current test method requires six samples of each type of armor to be tumbled in something like a commercial dryer with a controlled heat and humidity to simulate wear and tear before they are subjected to the live fire test.

NIST worked with the U.S. Army and the U.S. Department of Justice (DOJ) to develop the first generation of these tests in the 1970s. Today, NIST partners with the NIJ, the research arm of the DOJ, to develop standards and Bulletproof body armor. The DOJ provides funding to police departments to buy vests that have been shown to be trustworthy by adhering to those standards and passing those tests. While we would hope that no officer should ever have their armor tested in the field, testing and standards for body armor reassures us that the armors they wear will perform for them when they need it most.

As we can see traffice police everyday, they wear safety reflective vest when they work. Today, we want to explain everything you need to know about reflective tape, including the relevant regulations.

How Does A Reflective Vest Work?

What is reflective tape and how does reflective tape work?

Reflective tape is an essential vehicle safety product. Also known as vehicle contour or conspicuity tape, it improves safety by making the edges of large vehicles more obvious to other road users, reducing the risk of accidents and their severity.

Retroreflective tape works by sending light directly back to its source, making it clearly visible, and is arranged so as to delineate the outline of the large object in question. Reflective tape can be air-celled or solid construction, with the latter proving the most durable, long-lasting option.

Reflective tape applications

High quality reflective tape has a multitude of uses. Whilst it is most commonly used for the delineation of HGVs, trailers, and emergency vehicles, it is also commonly applied to PPE to protect the safety of those working on highways and in other areas of low visibility.

Reflective tape can also be used by cyclists, motorbike riders, and other vulnerable road users to increase their visibility. Some people also choose to use reflective tape on parts of a property that might be hard to make out. For example, around gateways and driveways to make any obstacles more easily discernible in the dark.

Based on the previous introduction to bulletproof vests. I believe everyone has a certain understanding of the functions, appearance, and how to choose bulletproof vests.

Today we- China Xinxing Guangzhou Imp&Exp Co., Ltd. will introduce the components of bulletproof vests. Let everyone have a deeper understanding of bulletproof vests.

1. Material.

As we know, There are currently only two types of bulletproof products - PE and aramid. Same to the bulletproof vest. The beginning of manufacturing bulletproof vests is to cut the outline of the vest on the woven fabric（UD fabric）. Used to create bulletproof panels. It is usually cut according to the size of the protective area of the bulletproof vest.

UD fabric(PE or Aramid). This fabric also we can sell.

2. Bulletproof panel

After cutting is completed. We will get many pieces of fabric cut according to the size of the bulletproof vest. At this point, we need to stack them all up. Like this:

It is necessary to determine how many layers of fabric a panel needs based on the protection level and material composition. For example, If the PE UD fabric areal density is 160g/m2 so NIJ IIIA 9mm need 22 layers and NIJ IIIA.44 need 30 layers. 

After all are neatly stacked. Putting on a coat will turn it into a bulletproof panel.

3. Put into the jacket.

The lining is completed. We need to put him in the coat. The jacket has become bulletproof due to the addition of the bulletproof panel. At this point, a bulletproof vest was born.

The above is the general production process and components of a bulletproof vest. If you are interested in these products, please do not hesitate to contact us: mail@cxxgz.com

In our last blog post, we learned about the composition of bulletproof vests（How Many Parts Does A Bulletproof Vest Consist Of?）

Today we- China Xinxing Guangzhou Imp&Exp Co., Ltd.  will introduce the types of bulletproof plates.

The bulletproof plate can be placed inside our bulletproof vest or tactical vest. To achieve a higher level of bulletproof performance.  Usually, bulletproof vests can only reach the bulletproof level of NIJ IIIA. Usually, bulletproof vests can only reach the bulletproof level of NIJ IIIA. Tactical vests are not even bulletproof. 

And the bulletproof plate can reach NIJ III and NIJ IV. Then our bulletproof plates is placed behind the interlayer of the bulletproof vest or tactical vest. It will increase the bulletproof level.

Now let me introduce several commonly used materials for bulletproof plates.

1. steel

Steel bulletproof panels have been in use since World War II and dominated the mainstream market for bulletproof inserts several decades ago.

This material is relatively heavy. Moreover, when the bullet hits the steel plate, the scattered fragments after the bullet shatters can easily cause secondary damage to the user. The advantage is that the price is very low.

But with the changing times. The emergence of other new materials has led to the gradual elimination of this material. But some countries still use it.

2. PE(Supramolecular polyethylene)

We mentioned this material in our previous blog post. He is the main material for making bulletproof vests and helmets. It is also a material for making bulletproof plates.

Generally, pure PE can be used to grade NIJ IIIA. 

NIJ III can also be made with pure PE. But the price will be more expensive than combining ceramics.  The advantage is that it is lighter than the material combined with PE and ceramics.

3. Combined with PE and ceramics.

This is the most commonly used material for bulletproof panels. Often used to make NIJ III and NIJ IV grade bulletproof plates.

Usually, ceramic materials include aluminum oxide and silicon carbide.  Both materials can meet bulletproof standards. And they are all combined with PE. Improving cost-effectiveness.

The price of alumina will be relatively cheap. Although silicon carbide is relatively expensive, its weight will be lighter.

The above is the general material of bulletproof plates. If you are interested in these products, please do not hesitate to contact us: mail@cxxgz.com

With the continuous advancement of weapon technology such as rifles and the occurrence of war, the choice to buy body armor for self-defense becomes critical. 

But there are many styles of bulletproof vests.  How to choose the style that suits you? 

Today CHINA XINXING GUANGZHOU IMPORT AND EXPORT CO., LTD which has more than 30 years of bulletproof products manufacturing history will tell you how to choose a right bulletproof vest for you, help you to save time.

1. CONCEAL BULLETPROOF VEST

CONCEAL BULLETPROOF VEST is a concealable bulletproof vest. It’s designed to be worn under clothing for concealment. It is possible to wear a coat over a bulletproof vest to achieve the purpose of not attracting attention from others.

2. BASIC BULLETPROOF VEST

BASIC BULLETPROOF VEST is the most conventional vest is also the most common vest. Wear it directly on the outside to protect the torso.

3. TACTICAL BULLETPROOF VEST

TACTICAL BULLETPROOF VEST is a bulletproof vest with the MOLLE system. The webbing on the chest can be put into a number of accessory bags to provide combat assistance, such as magazine bags, flashlights, medical kits.

4. FULL PROTECTION VEST

FULL PROTECTION VEST is  a bulletproof vest for all-round protection. Different from the above three, it adds protection for the shoulders, neck and thighs. The protective area is larger. It is usually used in the military as well as the police.

In addition to the above-mentioned paragraphs. There are also many special bulletproof vests. For example, water bulletproof life jackets, police dog body armor. If you are interested in purchasing or learning more, please contact us.

Tactical vests, plate carriers, and bulletproof vests are all considered protective equipment. Highly popular and valued in the military and police field. But how do we choose them when purchasing? What are the differences between them?

Today we- China Xinxing Guangzhou Imp&Exp Co., Ltd.  will introduce tactical vest, plate carriers,and bulletproof vest. And introduce the differences between them.

1.What is tactical vest?

2.Plate carriers

These vests are typically used by law enforcement and military personnel. Tablet vehicles are easily available in the market and can also be purchased and used by civilians. Plate carriers are usually also a type of tactical vest, with shoulder straps and belts (or belts) that can help you tightly tie things to your body. It has pockets on both the front and back for ballistic plates - giving tactical vests bulletproof functionality.

3.Bulletproof vest

A bulletproof vest helps absorb or transfer the impact of weapon strikes or bullets. They are composed of multiple layers of woven or laminated fibers, aimed at slowing down, dissipating, and stopping bullets. These vests can protect the wearer from gun damage, including bullets from pistols and assault rifles. Bulletproof vests are usually made of PE material. This is the most cost-effective vest material. Plus a layer of 600D Oxford cloth on the outside. And there is a sandwich inside that can be inserted into a bulletproof plate to upgrade the protection level of the vest.

The above is an introduction to three types of vests. Different uses can correspond to different styles. Of course, there are also more styles for you to choose from. We provide customized services.

We always believe. The right is the best.

Nowadays, with the advancement of technology. The market for bulletproof products is growing, such as bulletproof vest, bulletproof helmet and bulletproof plate. Many suppliers have emerged. Although price is important when purchasing these products, quality cannot be ignored. At this point, we need bulletproof testing to check the quality of the product.

Today we- China Xinxing Guangzhou Imp&Exp Co., Ltd.  will introduce the basic process of bulletproof testing.

Ballistic testing in China is usually conducted indoors. Strictly managed by specialized government agencies.

Firstly, we will fix the product to be tested in the testing position.We will place the tested product on this special adhesive. Adhesive can simulate the human condition after being hit by a bullet. 

Some bulletproof agencies also place their products on mannequins.

There will be a speedometer in the test. After the bullet is fired from the muzzle, it will pass through a speedometer. From this, the speed of the bullet in the test can be determined. The speed of bullets is also an important indicator for evaluating bulletproof products. Obtain the parameters of V50.

The tester will fire the corresponding bullet onto the product. After taking photos, take evidence based on the situation of the product being hit. Based on the comprehensive analysis, we can obtain the test report for this bulletproof product.

The above is the general process of bulletproof testing. Select different bullets and testing plans based on the bulletproof level of the bulletproof product and the different products.

Our company supplies bulletproof products to governments of various countries year-round. And they will frequently repurchase. Highly appreciated by clients from other countries. If bulletproof products are needed. You can contact us in a timely manner: mail@cxxgz.com

Looking forward to your inquiry.

The military beret was first used by the French Army - Chasseurs Alpins in 1889. British General Hugh Elles used the beret for the Royal Tank Regiment after seeing it during World War I. Soldiers need to crawl in and out of tank, and berets can be used to protect their hair.In 1924, tankers introduced a black wool beret with an adjustable ribbon that could be looped around the back and tied. Subsequently, in the 19th century, berets were mass-produced in Spain and England, and later became part of the uniforms of many military and police units around the world.

Military berets are made of wool or acrylic, with a headband or sweatband attached to the wool, made of leather, silk or cotton, sometimes with a drawstring that allows the wearer to tighten the hat. Berets are usually without lining, but linings can be added on demand.Berets can also be made in a variety of colors, and different badges are pasted on the beret to distinguish different troops.

China Xinxing Guangzhou Imp&Exp Co., Ltd specializes in the production of berets, equipped with large working machines,we can produce 170,000 berets per month.
