In order to improve the running performance of spandex during spinning, silicone oil lubricants and other auxiliaries are used in the weaving process. These additives degrade naturally over time resulting in yellowing of the fibers and decreased elasticity of the fabric. At the same time, spandex fabrics in long-term storage will form a cold set, so that the fabric can not be eliminated in the post-processing of permanent wrinkles. Therefore, in addition to reducing storage time, the spandex knitted fabric is more important to open the open width immediately after weaving to avoid the opportunity of creasing.
