一、用途
该系列锭子是包覆机上的关键部件，用于将真丝、涤纶等化纤长丝及棉花等纤维螺旋形缠绕在氨纶芯线上（双色或单色）使包覆丝既具有氨纶的弹性，又具有外包丝的外观及手感，为生产弹性机织物、针织物提供理想的包覆丝原料。
Application
As a key part ofcovering machine, the series are used for winding the chemical fibres like silk,polyester filament or cotton on the spandex core yarn (single color or doublecolors) in helix. In this way, the covering yarn will get not only theelasticity as spandex but also the appearance as the outsourcing yarn, whichcan supply perfect covering yarns for producing elastic woven and knit fabric.
