涤纶细旦丝的结构与工艺特征

The Structural and Technological Gharasteristics of PET Fine Filaments

细旦丝在单丝纤度、表面形态和超分子结构等方面从制造过程到成品均具有明显的特征。从结构和性能方面分析,细旦丝的最大单丝纤度应不超过1.5dtex(1.3D)。细旦丝的生产工艺要适应细旦丝的结构。文中着重从仿真丝的角度讨论了各参数的影响,并强调了网络加工的重要性。

There are distinct characteristics in filament titers, surface morphology and super molecular stru sture from the beginning of process to the finished products of PET fine filaments. Based on the analysis of structure and properties, the maximum filament titcr of fine filaments should not over 1.5 dtex (1.3d) and the processing technology of fine filaments should be adapted to the structure of fine filaments. In this paper, the influence of various parameters is discussed from the view point of silk imitation, the importance of interlacing process is emphasized.
