“…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.

“…Several studies have produced hybrid fibres by blending PA6 with other materials such as low density polyethylene (LDPE) [23], cellulose acetate butyrate (CAB) [24], polypropylene (PP) [25], chitosan [26] and polyethylene terephthalate (PET) [27]. The blending of polyamide with TPU in injection moulding and compressed mould have been reported [28][29][30][31][32] but there is a paucity of reported work on fibre blending of PA6 and TPU.…”

IntroductionIn recent years, nanofibers are recognized as an exciting new class of material for various applications.One of the well-known methods for the production of nanofibers is electrospinning, however it can be said that the utilization of the preparation of islands-in-thesea type bicomponent fibers (S/I fibers) for the production of nanofibers has an advantage of higher controllability of the diameter and mechanical properties of nanofibers [1]. In this technique, the sea component is dissolved into solvent after the formation of S/I fibers. Eventually, structure development and solidification behavior of the spin-line would be affected by the 【Transaction】 Abstract : To investigate the fundamental melt spinning behavior of the islands-in-the-sea (S/I) fibers, bicomponent melt spinning of polystyrene (PS) and polypropylene (PP) with the composition of 1 : 1 was performed using a spinning pack for preparation of S/I fibers with 1519 islands in the fiber cross-section. The sheath-core (S/C) fibers and blend fibers of the same composition were also prepared for comparison. The reduction ratio of the cross-sectional area of polymer flow from the position of the confluence of two polymer flows to the die exit for the sheath-core type spinning pack is 16 : 1, whereas that for the islands-in-the-sea type spinning pack is 3200 : 1. In this research, particular attention was paid to the behavior of polymer flow in the vicinity of spinneret. Magnitude of die-swell decreased with the increase of extrusion temperature. It was also found that the swelling was more significant for the S/I spin-line in comparison with that for the S/C spin-line. When the S/C and S/I components were exchanged from PS/PP to PP/PS, the swelling behavior of S/C spinline decreased whereas that of S/I spin-line did not show any significant change. On the other hand, magnitude of die-swell for the blend spinning was larger than that for the S/I and S/C spinnings and increased with the increase of extrusion temperature. The distance from the spinneret surface to the position of maximum spinline diameter increased in the order of S/C
