Nylon spandex fabric, also known as nylon elastane or nylon lycra, is made from a blend of nylon and spandex fibers.

Nylon is a synthetic polymer that is known for its durability, strength, and resistance to abrasion and chemicals. It is commonly used in various types of textiles due to its high tensile strength, which means it can withstand a lot of stretching without breaking or losing its shape.

Spandex, on the other hand, is a synthetic elastomer that is known for its exceptional stretch and recovery properties. It can be stretched up to 500% of its original length and will return to its original shape once the tension is released.

When these two fibers are combined, they create a fabric that is both strong and stretchy. The nylon fibers provide the fabric with its durability, while the spandex fibers give it its elasticity. Nylon spandex fabric is commonly used in the manufacturing of sportswear, swimwear, lingerie, and other types of apparel that require a high degree of flexibility and comfort.
