“…By contrast, few studies have tried to investigate the morphological variations of polymeric blend systems after extrusion from the spinneret orifices into fibers . However, these investigations were focused on investigations of the morphology of blend samples at only two positions along the spinline: blend extrudates at the die exit without stretching and the as‐spun filaments on the bobbin. Recently, the study by Tran et al .…”

The effects of the extrusion rate on the morphological changes of poly(lactic acid) (PLA)/poly(vinyl alcohol) (PVA) blend through a capillary die were investigated. In this study, the extrusion rate or mass flow rate is altered from 0.5 g min−1 to 2 g min−1 with an increment of 0.5 g min−1. The PLA/PVA blend with a composition of 30/70 (wt %) exhibits a particle matrix morphology with dispersed PLA droplets within the PVA matrix. It is found that, the spherical or ellipsoidal dispersed PLA droplets are elongated and coalesced into rod‐like or longer ellipsoidal droplets when they pass through the capillary die. When the extrusion rate increases, the coalescence between the large PLA droplets occurs more intense. However, the changes of the extrusion rate have no strong effect on the coalescence of small droplets having diameter less than about 150 nm. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

“…The understanding of the formation of micro‐ and nanofibrillar structures of polymer blends within the fiber formation zone in the melt spinning process came recently into the focus of considerable academic and industrial interest because it helps tailoring and controlling the final morphology of the dispersed phase in polymer blends . Recently, in our study, we found that during melt spinning under specific spinning conditions (take‐up velocity of 50 m min −1 and mass flow rate of 1.0 g min −1 ) the morphology of the dispersed poly(lactic acid) (PLA) phase was changed from rod‐like micro‐scale structures into continuous long nanofibrils within the fiber formation zone.…”

The effects of spinning conditions on the fibrillation process of poly(lactic acid) (PLA) and poly(vinyl alcohol) (PVA) polymer blends in an elongational flow within the fiber formation zone are systematically and thoroughly investigated. By considering the relationship between the changes in filament parameters with the focus on the maximum axial strain rate (ASR) and tensile stress at maximum ASR and the morphological evolution of the dispersed PLA phase along the spinline, the fibrillation process from rod‐like to nanofibrillar structures of the dispersed PLA phase in a binary blend with PVA matrix is elucidated. The final morphology of the dispersed PLA phase in PLA/PVA blends is controlled by the changes in the spinning conditions. The lengths and diameters of the PLA fibrils are caused not only by the deformation of their initial sizes but also by the combination of the deformation, coalescence, and break‐up process. © 2016 Wiley Periodicals, Inc.

“…The melting and mixing process can generate morphologies ranging from dispersed drops to fibers to lamella to co-continuous structures [33], see Figure 2. The initial morphology of immiscible polymer blend fibers is usually represented as a droplet-matrix or fibril-matrix morphology [31,32,[34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. The strategy to produce lamellae and other morphologies is more difficult than that required for the droplet-matrix morphology since the interfacial tension tends to minimize the surface of the second phase [7].…”

Melt spinning is an efficient platform to continuously produce fiber materials with multifunctional and novel properties at a large scale. This paper briefly reviews research works that reveal the morphology development of immiscible polymer blend fibers during melt spinning. The better understanding of the formation and development of morphology of polymer blend fibers during melt spinning could help us to generate desired morphologies and precisely control the final properties of fiber materials via the melt spinning process.
