Bulletproof Vest
Zhangjiagang City Yudun Special Fiber Co., Ltd.
Established in 2009, our company has been engaged in the R&D, production, and marketing of aramid fiber products in China. After years of continuous effort, our products have developed into two major series: military and civilian.
Military products mainly include ballistic helmets (made from Aramid or UHMW-PE), Aramid UD ballistic panels, Aramid UD fabric, and Aramid woven fabric. These are primarily used for bulletproof vests and bulletproof helmets.

The Different Layers of Protection
There are three main layers of protection which make up the composition of a bulletproof vest:
Ballistic Material
The layers of woven Kevlar vest are skillfully sewn together using Kevlar thread, ensuring the robustness and strength of the garment’s structure.
Outer Shell
The ballistic panels provide the majority of the all-important protection, however, the garment still needs to be comfortable to wear. To ensure this, the panels are placed within an abrasion-resistant polyester/cotton blend, or nylon fabric shell.
Trauma Reduction Layer
The inside of the shell is fitted with a shock absorbing material, as well as additional nylon padding to provide additional protection from trauma. This includes damage from blunt-force objects, as well as motor vehicle collisions.
What Are Bulletproof Vests Made Of
Bulletproof vests are made from vest-shaped panels of advanced plastic polymer, composed of materials such as kevlar, Polyethylene (PE), Steel, Ceramic, and more.
The outer shell is made from abrasion-resistant fabrics, such as polyester/cotton blends, or nylon.
Based on the composition of bulletproof vests, they are classified into five levels of ballistic protection (IIA, II, IIIA, III, IV) as per the National Institute of Justice.
Production
The production process for bulletproof vests involves multiple stages, including material selection, cutting, and assembly.
Material selection
The first step in the production of a bulletproof vest is selecting the appropriate materials. Manufacturers typically use a combination of Kevlar, Spectra, and Dyneema to create the protective material.
Cutting
Once the materials are selected, they are cut into the desired shape and size using specialized cutting machines.
Assembly
The cut pieces are then assembled into a vest, using either a sewing machine or heat-sealing process. The number of layers and the placement of the layers can vary depending on the level of protection required.
Testing
Once the vest is assembled, it undergoes a series of tests to ensure that it meets the required standards for ballistic protection.
