On page 970 , Yongchun Zeng and colleagues report the fabrication of microscale helical fibers from polymer blends using melt‐blowing technology. These fibers have been of increasing interest due to their unique structure and characteristics. An elastomeric and a stiff polymer are chosen as the raw materials, and a swirl‐die melt‐blowing device is then used to preparemicrofibrous nonwovens. The cover shows an SEMimage of the fabricated PP/TPU helical microfiber with a three‐dimensional spiral shape that resembles the tendrils of the calabash plant. Focusing on the interfacial interaction between the polymer components induced by the polymer properties, airflow field characteristics, and processing parameters, themechanismof helical fiber formation is explored.
