Knit Lycra fabric, also known as spandex or elastane, is a type of stretchy fabric that is commonly used in activewear, dancewear, and swimwear. It is made from a synthetic fiber that is highly elastic and resistant to wear and tear.

Knit Lycra fabric is known for its ability to stretch up to several times its original size and then return to its original shape without losing its elasticity. This makes it ideal for form-fitting garments that require a high degree of flexibility and movement.

The fabric is made by knitting the Lycra fibers together with other fibers such as cotton, polyester, or nylon. This results in a soft, comfortable fabric that is lightweight and breathable.

Knit Lycra fabric comes in a variety of weights and finishes, from lightweight and sheer to heavy and opaque. It is also available in different colors and patterns, making it a versatile choice for a wide range of applications.

Overall, knit Lycra fabric is prized for its combination of stretch, durability, and comfort, and is a popular choice for athletic wear, dance costumes, and other form-fitting garments.
