The effect of temperature on the distorting and breaking up of droplets is produced mainly by changing the properties of crude oil, especially the viscosity. 温度改变原油性质来影响水滴的变形断裂,其中粘性阻力起主导作用。
The main factors that had influence on breaking strength of PA6 yarn were discussed. The experimental result showed that the breaking strength could be improved by increasing drawing ratio, spinning velocity and chip viscosity. 讨论了影响PA6帘子线原丝断裂强度的主要因素,试验表明:提高拉伸倍数、增加纺丝速度及切片粘度均可提高原丝断裂强度。
