水性色浆在再生纤维素纤维原液着色中的应用

Application of Water-based Pigment Dispersion in Mass Coloration for Regenerated Cellulose Fibers

介绍了再生纤维素纤维原液着色对所用水性色浆的性能要求,以及黏胶纤维、莫代尔纤维、Lyocell纤维等不同再生纤维素纤维原液着色技术的研究现状和生产工艺优化情况。提出了提升原液着色用水性色浆与纤维纺丝原液的相容性、降低色浆粒径分布、规避环境安全风险、避免颜料颗粒对原液着色纤维力学性能的影响以及优化纺丝工艺等推进该技术应用的重要措施。

The main technical requirements of the water-based pigment dispersions used in the mass colored regenerated cellulose fibers were discussed. The research status and production process optimization about the mass coloration technology adopted to pro- duce regenerated cellulose fibers were described for viscose, modal and lyocell. The important measures to promote widely applica- tions of mass coloration technology were proposed, such as improving the compatibility of the pigment dispersion and the spinning so- lution, decreasing the particle size distribution of pigment dispersion, avoiding the environmental hazard and the influence of pigment particles on fabric mechanical properties and optimizing the production process.
