The common swimsuit fabrics on the market are mainly polyamide/spandex, polyester/spandex blended at present, which have some defects such as easy deformation, short service life etc. Sorona is a new kind of biomass fiber with low carbon and environmental protection, which has more superior performances than spandex that could ensure the fabric elastic lasting and stable. The paper uses seamless technology to weave new polyamide/Sorona/spandex swimsuit fabric, and compare with the ordinary polyamide/spandex, polyester/spandex fabric, by testing the specimen of tensile elasticity, elastic recovery and plasticity deformation rate, burst strength, and many other swimsuit related performance metrics. Come to conclusions: polyamide/Sorona/spandex fabric with superior elasticity, good comprehensive performance of elastic recovery and plastic deformation rate, excellent burst resistant performance, small hygroscopicity and fine permeability is suitable for swimsuit fabrics, providing reference for the development of high comfort seamless swimwear fabric.
