对熔纺和熔喷两种工艺的纤维温度和直径进行了在线测量。用红外热像仪测定纤维温度，用高速摄影法测定纤维直径。然后将这些测量结果与熔融纺丝和熔喷数学模型所作的预测进行比较。模型与实验结果之间有很好的一致性，当采用专门针对细纤维(圆柱体)建立的传热关联式时，一致性最好。
Online measurements of fiber temperature and diameter were made for both the melt-spinning and the melt-blowing processes. The fiber temperature was determined by infrared thermography, and the fiber diameter was determined by high-speed photography. These measurements were then compared with predictions made with mathematical models for melt spinning and melt blowing. There was good agreement between the models and the experimental results, and the agreement was best when heat-transfer correlations developed specifically for fine fibers (cylinders) were used.
