Chemical fiber fabric is a new type of clothing developed in modern times, and there are many kinds. Here mainly refers to the pure spinning, blending or interweaving fabrics processed from chemical fibers, that is to say, fabrics woven from pure chemical fibers.
Except for fabrics blended or interwoven with natural fibers, the characteristics of chemical fiber fabrics are determined by the characteristics of chemical fibers woven into them.
Camouflage is a kind of camouflage military uniform that uses color blocks to blend soldiers' bodies into the background color.
Extended data:
origin
Camouflage uniforms were first used by the British army. 1864 65438+In February, British captain Harry Banat Ramstein organized an irregular army "British reconnaissance team" in Peshawar, Pakistan.
When making uniforms for the reconnaissance team, Ramstein chose khaki uniforms in view of the characteristics of bare yellow land and heavy wind and sand, so as to disguise himself during reconnaissance. In later combat operations, this military uniform played a good camouflage effect.
Originated from the camouflage clothing of Scottish bird hunters, the prototype of camouflage clothing can be traced back to the "Geely clothing" in Scotland. Originally a camouflage tool used by hunters, it is said that it was invented by the hunter Ghillie, and it is mainly used to hide in the jungle and paralyze birds for hunting.
The original Geely clothing is a coat decorated with many ropes and cloth strips, which has a good hiding effect in the dense vegetation environment and is difficult for even alert birds to find.

Geely clothing was popularized in World War II and renamed as "sniper clothing". Snipe is famous for its quick action and difficult hunting. People who are good at hunting this kind of bird are called snipers, and later they become proper terms for snipers.
1899, British troops invaded South Africa and launched a three-year "Ying Bu War" with local Dutch descendant Buboer. The Boers have fewer troops and the British have more. The strength comparison between the two sides is about 1: 5.
However, the Boers found that the British army wore red uniforms, which were particularly eye-catching and easily exposed in the green of forests and prairies in South Africa. Inspired by this, the Boer people immediately changed their clothes and guns into grass green, which was easy to hide in the dense grass forest.
The Boers often approached the British army unnoticed and suddenly launched an attack, which caught the British army off guard, but it was difficult for the British army to find a target if it wanted to fight. Although the British army won the war in the end, the casualties of the British army exceeded 90 thousand, far exceeding the casualties of the Boer army.
This war made European countries realize the importance of personnel camouflage in the modern battlefield, and changed bright military uniforms into green or yellow one after another to achieve the purpose of concealment. After the First World War, the emergence of various optical reconnaissance equipment made it difficult for soldiers wearing monochrome military uniforms to adapt to the multi-color background environment.
1929, Italy developed the world's earliest camouflage clothing, which has four colors: brown, yellow, green and yellow-brown.
1943, Germany equipped some soldiers with tricolor camouflage uniforms, which were covered with three patches with irregular shapes. On the one hand, these patches will distort the outline of the human body; On the other hand, the color of some patches is similar to the background color, and some patches are obviously different from the background color, so as to segment the human body shape from the visual effect, thus achieving the effect of camouflage deformation.
German camouflage uniforms have achieved good results in actual combat. Later, the armies of various countries followed suit and studied and improved the color of camouflage and the shape of patches.
After 1960' s, the newly developed camouflage clothing is made of synthetic chemical fiber, which is not only superior to the original cotton material in preventing visible light reconnaissance, but also has a certain camouflage effect of preventing infrared light reconnaissance because of mixing special chemicals with colored dyes, which makes the infrared light reflection ability of camouflage clothing roughly similar to the surrounding scenery.
Now camouflage is not only used in soldiers' uniforms and helmets, but also widely used in various military equipment such as airplanes and military vehicles.
