Abstract

ABSTRACT: The drying of microcapsules causes agglomeration and oversized agglomerates disturb fiber melt spinning. In this study, three parameters in co-current spray drying were studied and their influence on agglomeration was established with a morphological analysis, granulometric analysis, differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA). The results showed that the inlet temperature, feed rate, and dry matter content have a significant influence on agglomeration; thus, their optimal combination was determined. In these conditions, the microcapsules were dried and applied in fibers.
