由于对紧身和由可伸缩纤维制成的舒适服装的需求日益增长，氨纶纤维正被用于内衣、尿布、袜子、休闲服、运动服和牛仔裤等。采用自行设计的多段并条机和环锭细纱机生产了涤纶氨纶包芯纱。测试了包芯弹性纱在不同工艺条件下的力学性能。分析结果表明，当氨纶纤维的主牵伸倍数为2.2或2.7时，包芯弹力纱的断裂强力和断裂伸长率最大。
Owing to growing demand for figure hugging and comfortable clothes made with stretchable fibers, spandex fibers are being used in underwear, diapers, hosiery, leisurewear, sportswear, jeans, and so on. In the present study a polyester core-spun yarn containing spandex fibers was made using a self-designed, multi-section drawing frame and a ring spinning frame. The mechanical properties of the core-spun elastic yarns were examined in various processing conditions. The analytical results show that when the main drawing ratio of the spandex fibers was either 2.2 or 2.7, the maximum breaking tenacity and elongation of the core-spun elastic yarns exceeded those in any other of the main drawing ratio conditions.
