摘　　要：文章以聚酰亚胺纤维干法纺丝过程为对象,选取纺丝温度、纺丝速度和纺丝风速3个关键要素,以其中心值为基础设计正交试验表,利用Fluent软件对二甲基乙酰胺(DMAC)在纺丝甬道内的蒸发状态进行模拟,并成功获得蒸发状态云图。通过对模拟结果的深入分析,探讨各因素对DMAC蒸发的影响规律,旨在为优化聚酰亚胺纤维纺丝工艺提供理论依据和技术支持,提高纤维质量和生产效率,同时减少环境污染。The article focuses on the dry spinning process of polyimide fibers,selecting three key elements:spinning temperature,spinning speed and spinning wind speed.Based on their central values,an orthogonal experimental table is designed to simulate the evaporation state of dimethylacetamide(DMAC)in the spinning channel using Fluent software,and a cloud map of the evaporation state is successfully obtained.Through in-depth analysis of simulation results,the influence of various factors on DMAC evaporation is explored,aiming to provide theoretical basis and technical support for optimizing polyimide fiber spinning process,improve fiber quality and production efficiency,while reduce environmental pollution.
