Several categories of protective clothing Protective clothing is designed to provide protective clothing for specific industries. How about the classification of protective clothing? What is the classification of protective clothing? What are the differences between different kinds of protective clothing and what conditions apply? 1 Body armor As the name suggests, bulletproof vests are protective garments that can effectively protect a variety of ballistic missiles. They were developed after the Second World War and are the key to effective protection of commanders and soldiers from bullets and shrapnel until the final victory in modern warfare. At present, it has become an indispensable protective product for the military and the police. It is particularly valued abroad and has developed rapidly. So far, there are many types of body armor. According to the materials used, they can be divided into soft body armor, hard body armor and soft and body armor. Body armor is mainly used for protection in two aspects. The first is to protect bullets from pistols and rifles. After the bullet hits the target, it deforms. It consumes part of its own kinetic energy in the process of deformation. The bullet speed is small and easy to intercept. The use of soft body armor can provide good protection. The bullet speed of the military rifle is very high. Big, it is better to use soft and bulletproof body armor. Second, we must also protect the explosive shrapnel. According to statistics, 80% of the casualties in the Vietnam War were hit by shrapnel and 20% were hit by bullets. These shrapnel are smaller than bullets, have sharp edges, do not degenerate after hitting targets, and are more lethal. There are many protective mechanisms for body armor, but the basic mechanism is to completely dissipate the kinetic energy of the parabolic body in the stretch fracture of the body armor yarn. Factors affecting the energy absorption properties of the bulletproof system include the properties of the constituent materials, the design parameters of the fabric, the number of fabric layers, the density of the fabric, and the impact parameters such as the mass, speed, and geometry of the shot. 2 Anti-nuclear clothing The effects of nuclear weapons are related to their size, equivalents, and types, and they vary with the height of the explosion, the characteristics of the area, and the circumstances of the environment. Due to the short duration of flashing, any type of shield (thin sheet metal, clothing, or building) can have significant protection. Burns caused by scintillation are not only in the exposed parts of the body, and are therefore related to the thickness of the garment. Even if the thickness of the garment is not significantly increased, there is a large difference between burning and not burning. Wearing tight clothing can cause burns, while wearing loose clothing can be protected. The primary requirement for flame-proof burns is that the outer clothing is flame-retardant and can dissipate the greatest amount of radiant heat. When the outer garment has absorbed radiant heat and is delivered to the inner garment, the anti-nuclear garment can remain intact as long as it protects the inevitable radiant heat. At present, the use of polyester-cotton blended fabrics in the United States against nuclear clothing has the advantage of better durability for the removal of fouling. Newly developed fabrics usually contain 1% carbon fiber, others are nylon, and sometimes blends of nylon and polyester. 3 Anti-biochemical clothing The United States uses infiltration, semi-permeable, and impermeable material systems to prevent biological weapons. The infiltrating system uses activated carbon as a lining cloth, which is permeable to moisture and can prevent chemical substances. The nylon warp knitted fabric is used as a base fabric and is coated with an activated carbon-rich polyurethane foam. Since the activated carbon has a good adsorption performance, the surface layer can be effective. Absorb chemical gas substances. Surface treatment can be used to prevent liquid penetration. The semi-permeable system in the form of a coating and a coating can be designed as a microporous and ultra-microporous material having various pore sizes, and has a high wet vapor transmission rate, good water pressure resistance, and the best balance between chemical resistance and biological resistance. The use of foam-enriched activated carbon microporous semi-permeable membranes is used by the US pilots' anti-biochemical combat uniforms. In the Gulf War, Germany launched three new types of chemical protective clothing. Its use of activated carbon foam particles in drug filtering materials has a very good protective effect. It can completely prevent the poisonous gases and liquids from poisoning and can withstand three rounds of mustard gas within 24 hours. Offensive. 4 Camouflage clothing Camouflage clothing is more typical and common is camouflage clothing, only one camouflage, all countries make a fuss. Japan's camouflage uniforms were replaced by the original four-color camouflage patterns in the spring, summer, and autumn seasons that could be easily incorporated into the bamboo groves during the day. They were replaced with new camouflage combat suits and used slim four-color camouflage. Divided into spring and summer and fall colors, it has non-flammable properties. Since all the fabrics with the same infrared radiation rate as the environmental plants of each season were used, the performance of the infrared ray detection was improved, which means that nighttime operations that temporarily lost value because of the night vision equipment have once again restored tactical advantages. The Japanese Ground Self-Defense Force was equipped with a fire-resistant camouflage combat uniform in 1992. It was composed of a top coat and trousers. It was fire-resistant due to the use of flame-retardant fibers. It also used excellent camouflage paint to effectively cope with enemy night-vision devices. The effectiveness of infrared detection is good and concealment is good. Although all countries are making efforts, it is only required that camouflage clothing be protected against visual disguise. Using various color patterns similar to the background environment is insufficient to meet the needs of modern warfare. Modern detection equipment can emit ultraviolet rays through complete multi-sensing systems such as visible, black-and-white, color, imaginary, radar through the leaves, and long-distance sensors, and can be reconnoitred by close-range and long-range infrared, radar, and seismic waves. With such advanced equipment, it seems impossible to achieve the purpose of preventing reconnaissance using only the current single means. In a battle, the background cannot always be consistent. The U.S. military is developing camouflage fabrics for the urban background called the Urban District 0, and another camouflaged form mimicking a reticular night-vision goggle has passed the Pentagon test.
