Primary Uses for Silk Fabric
Silk is primarily used in garments and household items, but it is also employed in unexpected ways, such as in bicycle tires and in medicine. Silk is great for summer clothing because of its absorbent nature and how it wicks moisture, and it is also a staple for winter wear since it has low conductive properties. Here are some examples of the material’s many uses.
Bridal and formal wear. Silk is a staple of many gowns and dresses thanks to its beautiful drape, and the long floats of yarn on one side create a dressy and lustrous appearance.
Ties and scarves. The material’s strength and nuances with color make it ideal for accessories. Many high-end ties are made from heavy silk, which allows for tightly woven patterns, rich colors, and durable material. Silk is also a great material for scarves for both decoration and for warmth.
Bedding. Silk sheets are the height of luxury and the material’s softness and absorbent nature makes it truly shine in the bedroom.
Parachutes. Silk was originally used for parachutes for its strength and elastic properties; however nylon is more commonly used today.
Upholstery. Silk is used to cover furniture and pillows, and thanks to its strength and durability, it provides a long-lasting covering.
Wall hangings. Decorative wall hangings are often woven from silk, as the material is beautiful and dynamically reacts with colors and dyes.
Bicycle tires. The material is sometimes used in the tire’s casing because of its lightness, durability, and flexibility. Since silk can be expensive, the casings can also be made from nylon and cotton.
Surgical sutures. Since silk is a natural material, it has amazing uses in medicine. The material does not cause an autoimmune response and cannot be absorbed by the human body.
