【摘要】 本文研究了涤纶纤维的类型、纤度、纺丝速度、成形条件等因素对纤维的结构和性能的影响,采取了直接纺制细旦涤纶的方法,控制一定的纺丝和冷却条件,得到了一种不均一的纤维横截面结构。这一结构的形成是造成上染百分率提高的主要原因。更多还原

【Abstract】 In this paper, the influence of fibre type, tex number, spinning speed, formation condition,etc. was studied on structure and properties of fibre. The fine PET filament with nonuniform cross section structure was manufactured by direct spinning and controlling spinning and cooling conditions. The nonuniform sturcture of fibre cross section is the main reason for increased dye-uptake.更多还原
