​Silk is a lightweight fabric with a smooth surface, primarily made from silk fibers. It is the finest natural fiber, with a nearly triangular cross-section and high luster. Thanks to its prism-like triangular structure, silk reflects light at different angles, creating its signature iridescent sheen. The main component of silk fiber is fibroin (making up about 75% of the thread), produced during the cocoon-spinning process of silkworms that feed on mulberry leaves. The most common colors of silk fibers are vanilla or white. Additionally, some wild silkworm species produce naturally colored threads in shades of brown, orange, or pale green.

           Silk has a tensile strength nearly equal to steel and over 20% higher elasticity, making it a material used to produce protective clothing resistant to arrows and bullets. However, when wet, its strength decreases by about 20%, but it remains much stronger than many other fibers.​​

​Due to its superior properties, combined with its rarity and the labor-intensive, meticulous production process, silk commands a high price and is consistently ranked among the most expensive fabrics in the world.
