摘　　要：为探究纺粘非织造工艺中工艺参数对纤维最终直径的影响,文章基于纺粘非织造聚合物拉伸过程,构建了纺粘非织造聚合物拉伸理论模型,并应用MATLAB对模型进行数值计算。同时,选取纺粘工艺参数中的气流初始速度、聚合物初始温度、聚合物质量流量3个因素,通过控制变量法比较观察不同方案下经过数值求解后得到的纤维直径,得出3个因素分别对纤维最终直径的影响。结果表明,气流初始速度越大,聚合物初始温度越高,聚合物质量流量越小,最终形成的纤维直径越细。In order to explore the influence of process parameters in the spunbonding process on the final fiber diameter,the paper established a theoretical polymer drawing model of the spunbonding process based on existed drawing process,and numerically solved the model by MATLAB.At the same time,the initial velocity of air flow,the initial temperature of the polymer and the mass flow rate of polymer were selected to compare the final fiber diameter obtained by numerical solution under different schemes through the control variable method,and the influence of these three factors on the final fiber diameter was obtained.Results show that the larger the initial gas velocity is,the higher the initial temperature of the polymer,or the smaller the mass flow rate of polymer,the finer the diameter of the final fiber.
