Silk

General Information
Silk is a natural protein fiber that is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. In certain lighting conditions, silk produces a shimmering optical effect, which is due to the triangular prism-like structure of silk fibers. These prisms reflect light at various angles, which results in a subtle rainbow hue that makes silk popular.
According to World Atlas, China holds a dominant position as the world’s largest silk manufacturer. The cultivation of domesticated silk originated in China. Archaeological evidence dates the use of silk textiles in China back to 6500 BC, and the ancient Chinese certainly used silk as early as 3600 BC.
For the maintenance of silk, it is best for it to be taken to a dry cleaner or hand washed. The silk garment should be placed in cold water with a mild silk-friendly detergent and left to soak for no more than 5 minutes. It can be rinsed with cold water and left to dry.
Environmental Impact
Since silk is a natural fiber, it is inherently sustainable and non-damaging to the environment. The harvesting and production of wild silk do not have any negative environmental impact, but cultivating silk and transporting it around the world may harm the environment due to fossil fuel usage. Since most areas of the world don’t produce much silk, it’s necessary to ship it long distances to reach its final destination. Therefore, fossil fuels are expended in the process of shipping silk. Despite these minor concerns, silk production does not significantly harm the environment

Application
Silk can well absorb ultraviolet light and prevent noise penetrating through the air because of its pore structure. Therefore, silk is an ideal choice for home decoration. However, when it comes to window treatments, it is important to line silk curtains because the sunlight can rot silk and the curtains will not last very long.
