阐述了干法纺黑色氨纶生产技术的研究过程,介绍了相关生产工艺流程以及技术关键点,即采用高色素炭黑和超分散剂,选择适当的控制条件,研制出具有良好粒度分布(平均粒径约100 nm,最大粒径约400 nm)和着色性能的色浆。利用原液着色法,选择合适的炭黑添加量(相对氨纶丝质量分数约为0.5%),生产出符合干法氨纶纺丝要求的黑色原液,实现了黑色氨纶在现有生产线上的工业化生产。
The research process of dry spinning black spandex production technology is introduced. Relevant production process flow and key points of technology are introduced. High pigment carbon black and hyperdispersant are used to select proper control conditions. Diameter of about 100 nm, the maximum particle size of about 400 nm) and colorants. The raw liquid coloring method was used to select the suitable amount of carbon black (about 0.5% relative to spandex) to produce a black stock solution that meets the requirements of dry-process spandex spinning and realized the industrialized production of black spandex in the existing production line.
