Textiles in defence
Defence forces on land, sea, or air throughout the world are heavily reliant on technical textiles of all types – whether woven, knitted, nonwoven, coated, laminated, or other composite forms Technical textiles offer invaluable properties for military land forces in particular, who are required to move, live, survive and fight in hostile environments. They have to carry or wear all the necessities for comfort and survival and thus need the most lightweight, compact, durable, and high performance personal clothing and equipment .
Forces were using: bright, shiny and colorful dresses large epaulettes to increase the apparent width of the shoulders. Tall headwear made from animal furs (bearskin caps), feathers (ostrich), to increase the apparent height of troops. The materials used were all of natural origin, based upon wool and goat hairs, cotton, silk, flax  Such uniforms do not provide comfort during wearing.
The twentieth century defense clothing
Khaki colored uniforms from cotton twill or drill entered service for tropical use in 1902 It was found to give insufficient protection from the elements in temperate climates, so that wool worsted serge (twill fabric) uniforms were issued in the khaki or brown colors. For non-clothing textile items such as tents, shelters, covers, nets, load-carriage items and sleeping systems were made from natural fibers based upon wool, cotton, flax, jute, hemp, sisal, and kapok. Those used for screens, covers and tents were heavy, cumbersome, and prone to degradation by insects, moisture and biological organisms

Ventile was the first waterproof/water vapor-permeable fabric – invented by scientists at the Shirley Institute (now the British Textile Technology Group). It was based upon low twist Sea Island cotton yarns in a very tightly woven construction. Water-repellent finish (Velan® by ICI) improved the waterproofness of this technical fabric, which is still widely used today by many air forces.
