本文提出了一种基于实验的熔喷工艺的连续长丝制度的分析。实验使用多功能空气聚合物模头、几种模头操作温度和三种不同的聚合物进料树脂进行。测量辨别以下输入参数对最终纤维直径的影响：模头尺寸、模头温度、聚合物进料树脂以及空气和聚合物质量流速。经验模型方程的开发，这些输入参数的最终纤维直径。此外，导致长丝从连续（或稳定）到不连续（或不稳定）的过渡的条件被量化。然后，模型方程和转变或稳定性信息用于预测熔喷工艺的行为，用于涉及上述输入参数的广泛案例研究。这些数据和经验模型对于开发新的模头设计、与理论模型进行比较、预测纤维稳定性以及解释当前工业熔喷工艺的行为具有相当大的实用性。
This paper presents an experimentally‐based analysis of the continuous filament regime of the melt‐blowing process. The experiments were performed with a versatile air‐polymer die, several die operating temperatures, and three different polymer feed resins. The measurements discern the effects upon the final fiber diameter of the following input parameters: die dimensions, die temperature, polymer feed resin, and both the air and polymer mass flow rates. An empirical model equation is developed which relates these input parameters to the final fiber diameter. In addition, the conditions which result in a transition of the filament from continuous (or stable) to discontinuous (or unstable) are quantified. The model equation and the transition or stability information are then used to predict the behavior of the melt‐blowing process for a wide range of case studies involving the input parameters noted above. The data and empirical model are of considerable utility for developing new die designs, for comparison with theoretical models, for predicting fiber stability, and for explaining the behavior of current industrial melt‐blowing processes.
