Elasticity is a defining characteristic of sewing button hole knit elastic bands, providing them with the unique ability to stretch and return to their original shape. These versatile bands are widely used in garment construction, ensuring a comfortable and secure fit in various applications. However, the degree of elasticity can vary depending on several factors that come into play during the manufacturing process.

The choice of materials used in sewing button hole knit elastic bands plays a fundamental role in determining their elasticity. Common materials include natural rubber, synthetic rubber (latex), polyester, nylon, and spandex (also known as Lycra or elastane).

Natural Rubber: Elastic bands made from natural rubber are renowned for their high elasticity. The inherent stretch and recovery properties of natural rubber make it an excellent choice for applications where a strong and durable elastic is needed.

Synthetic Rubber (Latex): Synthetic rubber, also known as latex, is a synthetic form of natural rubber. While it offers similar elasticity, the exact degree of stretch can be tailored during the manufacturing process.
