Spandex fabrics are often made of composite yarns, that is, with spandex as the core, and other fibers (such as nylon, polyester, etc.) as the cortex to make core-spun elastic fabrics, which have good adaptability to the body and are very suitable for swimming wear cloth.

    Spandex has very high elasticity. Generally, 100% polyurethane is not used in general products, and the proportion of 5~30% is mixed in the fabric. All kinds of spandex fabrics obtained have a comfortable elasticity of 15%~45%.

    The appearance, style, and wearing performance of the spandex elastic fabric are close to those of similar products covered by the outer fiber fabric.

    Spandex fabrics have great extensibility, good shape retention, and no wrinkle. Soft and smooth to the touch, best elasticity, comfortable to wear, and considerate fit. In addition, it is resistant to acid and alkali, abrasion, aging, and has good dyeability, which is not suitable for fading.
