摘　　要：为研究针织物在转鼓式水洗机上冲淋水洗时,水洗工艺和辊网结构参数对水洗质量的影响,首先建立织物水洗质量动态评价项,评判染液在织物上的残留和分布状况。并利用Fluent软件,创建织物水洗域有限元模型,分析不同辊网孔型对水洗质量的影响。然后综合考虑染液残余率、染液均匀度和洗涤面积比,建立织物水洗质量综合评价函数,采用中心复合设计法生成系列设计点,获得织物水洗质量对水洗速度、水洗时间、辊网孔圆弧半径的响应曲线和灵敏度值,说明水洗速度对水洗质量综合评价值的影响最显著,其灵敏度值为68%。最后以提高织物水洗质量为目标,优化水洗工艺和辊网结构参数,优化后水洗质量综合评价值提高了16.1%。In order to study the influence of washing progress and the roller structure on washing quality when fabrics are rinsed on drum washing machine, three items describing the remains and distribution of dye solution on fabrics were defined firstly. A finite element model of washing region was built by Fluent, and the influences of different roller structures were analyzed. Considering remaining ratio of dyeing liquid, uniformity of dyeing liquid and washing area ratio comprehensively, evaluation function of washing quality was proposed. Using central composite design method, series of design points were obtained. Response curves and sensitivity values were achieved. It is shown that the influence of washing speed is the most significant reaching 68%. Finally, in order to improve the washing quality, washing process and roller structure were optimized. The result shows that the washing quality of evaluation function is increased by 16. 1%.
