消光聚酰胺56纤维及其制造方法
摘要：
种消光聚酰胺56纤维的制造方法,包含提供多个聚酰胺56全光树脂颗粒、进行粘度调整步骤、水分调整步骤与纺丝步骤。粘度调整步骤是使聚酰胺56全光树脂颗粒的硫酸相对粘度为2.90至3.00。水分调整步骤是使聚酰胺56全光树脂颗粒的含水量为350ppm至550ppm。纺丝步骤包含提供多个聚酰胺6消光树脂颗粒与进行混炼步骤。聚酰胺6消光树脂颗粒包含二氧化钛,混炼步骤是将聚酰胺6消光树脂颗粒与进行过粘度与水分调整步骤的聚酰胺56全光树脂颗粒熔融混炼,于275℃至285℃进行纺丝,以获得消光聚酰胺56纤维。藉此,提升消光聚酰胺56纤维的均匀度及纺丝性。
摘要（英）：

A method for manufacturing a dull polyamide 56 fiber includes steps as follows. Bright polyamide 56 chips are provided. A viscosity adjusting step is provided, wherein a relative viscosity in sulfuric acid of the bright polyamide 56 chips is adjusted to a range of 2.90 to 3.00. A moisture adjusting step is provided, wherein a moisture content of the bright polyamide 56 chips is adjusted to a range of 350 to 550 ppm. A spinning step is provided, which includes providing dull polyamide 6 chips and a blending step. The dull polyamide 6 chips include TiO2. In the blending step, the dull polyamide 6 chips and the bright polyamide 56 chips dealt with the viscosity adjusting step and the moisture adjusting step are melted and blended, and then spun at a temperature ranging from 275° C. to 285° C., thus the dull polyamide 56 fiber is obtained.
