摘要
在变形纱中,空气变形类和异收缩变形类纱线具有皮芯结构,有必要对其成形原理和结构模型加以概括和总结。借助实验观察和理论分析的方法,认为虽然上述2种变形纱皮芯结构的成形原理不同,但模型都可以描述为紧密网络扭结的芯层和松散圈弧形态的皮层结构。结合EIB实验验证,可以进一步确认变形纱的皮芯结构参数主要包括纱线平均直径、纱芯平均直径和丝圈丝、弧高度等指标,因而也可断定变形纱皮芯结构与变形纱膨松度、变形纱条干均匀度以及变形纱毛羽的各项特性指标有密切关系。
In the textured yam family, both the air-jet textured yarns and the differential shrinkage textured yarns have the skin-core structure, so it is necessary to study its forming principles and its model. By means of experiments and analysis, it is believed that though these two sorts of textured yams are all different in their skin-core structure forming, the model of this structure can be defined as closely netted and kinked core plus loose loop skin structure. It is proven by EIB experiments that this model is characterized by several parameters such as average diameter of the yam, average diameter of the yarn core and the height of loop. So there must be some close relationship between the skin-core structure of textured yarns and some of its properties such as the bulkiness, evenness and hairiness.
