干法纺黑色氨纶生产技术的研发

Study on the Production Technology of Dry-Spun Black Spandex

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 the black Spandex production technology by dry-spinning was described, the production process flow and some key techniques were introduced. The dyeing slurry with average particle size 100 nm and the maximum particle size 400 nm was prepared at the suitable control condition from high pigment carbon black and hyperdispersant. The black solution for dry-spun Spandex can be produced with dope dyeing method. The preferable weight ratio of carbon black in the yarn was 0.5 %. The stable industrial production of black Spandex was realized.
