Copper/cotton core-spun yarns have been produced using siro and conventional ring methods, and their mechanical properties and cover factor are analyzed. The results indicate that the cover factor and tensile properties of copper/cotton core-spun yarns decrease with an increase in copper core diameter. Nevertheless, the siro copper/cotton core-spun yarns exhibit higher tensile properties as compared to conventional ring copper/cotton core-spun yarns.

西罗和环锭纺方法生产的铜/棉包芯纱的机械性能

铜/棉包芯纱已使用赛罗和常规环法生产，并对其机械性能和覆盖因子进行了分析。结果表明，铜/棉包芯纱的覆盖率和拉伸性能随铜芯直径的增加而降低。然而，与常规的环铜/棉包芯纱相比，西罗铜/棉包芯纱表现出更高的拉伸性能。
