The Characteristics Of Elastic Spandex Fabric

    Spandex is a kind of polyurethane fiber. Because of its excellent elasticity, it is also called elastic fiber. It has been widely used in clothing fabrics and sofa upholstery fabrics. Its varieties can be divided into warp elastic fabrics, weft elastic fabrics, and warp and weft two-way elastic fabrics according to the needs of the application.

    At present, the fabrics of fabrics are mostly natural fibers and artificial fibers. Cotton is a natural fiber with good air permeability and moisture absorption properties, but poor elasticity and is easy to deform. Artificial fiber is a kind of fiber that is artificially synthesized according to needs, which solves some of the shortcomings of natural fibers. Spandex is a kind of polyester fiber of artificial chemical synthetic fibers. Generally, different proportions of spandex are mixed into clothing fabrics to achieve the effect of increasing elasticity and comfort. It is widely used.

    Features of spandex fabric:

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

    Spandex fabrics are often made of composite yarns, that is, spandex is used as the core, and other fibers are used as the cortex to make core-spun elastic fabrics. It has good adaptability to the body and is very suitable for tights without the feeling of pressure.

    The appearance style and wearing performance of the spandex elastic fabric are close to those of the same kind of products covered with the outer fiber fabric.
