Silk is a luxurious natural protein fiber renowned for its rich luster, tensile strength, and smooth texture. Produced primarily by the larvae of the Bombyx mori (mulberry silkworm), silk consists mainly of fibroin—a protein that forms the structural center of the cocoon. Unlike many synthetic fibers, silk has a naturally soft and non-slippery feel, making it highly desirable in the textile and apparel industries.

While silk is recognized as the strongest natural fiber, it is sensitive to moisture and loses strength when wet. It also possesses moderate elasticity and a moisture regain of approximately 11%, allowing for comfort in wear and superior dye uptake. Among various silk types, mulberry silk is the most widely used due to its consistent quality and versatility. Other varieties include tussar silk, eri silk, muga silk, spider silk, and sea silk. Additionally, art silk (artificial silk) offers an economical alternative with silk-like appearance.

Silk is a preferred material in high-end applications such as luxury garments, bedding, nightwear, upholstery, and fashion accessories. However, its premium cost is attributed to the labor-intensive production process and limited availability. Furthermore, silk is sensitive to prolonged exposure to sunlight, which can weaken the fibers and lead to discoloration or tearing.

To improve affordability and functional properties, silk is often blended with fibers like cotton, linen, wool, and rayon. These blends maintain silk’s elegance while enhancing durability and reducing costs.
