“…Labscale nanofibres have been produced from many different techniques such as electrospinning, melt blowing, islands-in-the-sea spinning, template syntheses, drawing, phase separation, self-assembly and more recently, rotary jet spinning [16]. Of these lab-scale devices, only electrospinning, rotary jet spinning, and potentially melt blowing are capable of producing nanofibres on an industrial scale.…”

“…The rate at which nanofibres can be produced varies according to the method and production variables, but can be summarised by concluding that electrospinning is as much as 50 times slower at producing nanofibres compared to rotary jet spinning [16]. Industrial electrospinning machines such as Nanospinner416 by Inovenso Ltd. (Istanbul, Turkey) are capable of producing 210 g h −1 [18], whereas an industrial rotary jet spinning device, the FX2200 by FibeRio (McAllen, TX, USA), can produce up to 12,000 g h −1 [19] from a continuously produced 2.2 m wide nonwoven.…”

Abstract:Polymer nanofibres are created from many different techniques, with varying rates of production. Rotary jet spinning is a relatively new technique for making nanofibres from both polymer solutions and melt. With electrospinning being by far the most widespread processing method for polymer nanofibres, we performed a direct comparison of polyamide 6 (PA6) nanofibre production between these two methods. It was found that electrospinning produced slightly smaller-diameter fibres, which scaled with a decrease in solution viscosity. In comparison, rotary jet spun fibres could be produced from a reduced range of polymer concentrations and exhibited therefore slightly larger diameters with greater variation. Crystallinity of the fibres was also compared between the two techniques and the bulk polymer, which showed a decrease in crystallinity compared to bulk PA6.

“…Production rate coupled with scalable design enables the setup to produce fibers on an industrially relevant scale, in excess of other commercially available fiber production technologies . Even compared to commercially available electrospinning techniques the production rates are far greater . There are no obstacles that prevent its scale‐up and the design can be reconfigured by changing orifice density and shape, as well as the vessel volume to increase yield.…”

“…Forcespinning, a type of centrifugal spinning, can produce nanoscale fibers through careful design of geometry and morphology of spinnerets . These methods have demonstrated superior fiber yields compared to previous electric field–based methods and variations on these have been developed such as liquid shearing spinning, brush spinning, and magnetospinning …”

In this invited feature article, the invention of pressurized gyration in 2013 and its subsequent development into sister processes such as pressurized melt gyration, infusion gyration, and pressure‐coupled infusion gyration is elucidated. The fundamentals of these processes are discussed, elucidating how these novel methods can be used to facilitate mass production of polymeric fibers and other morphologies. The effects of the main system parameters: rotational speed and gas pressure, are discussed along with the influence of solution parameters such as viscosity and polymer chain entanglement. The effect of flow of material into the gyrator in infused gyration is also illustrated. Examples of many polymers that have been subjected to these processes are discussed and the applications of resulting products are illustrated under several different research themes such as, tissue engineering, drug delivery, diagnostics, hydrogels, filtration, and wound healing.

“…The production of polymeric nanofibers is a growing research field since the early work of D. H. Reneker in the 1990s . Applications ranging from drug delivery, wound dressing, filtration, sensors, composites, and battery separators call for production techniques characterized by low cost and high production rates.…”

The recently popularized method of rotary jet spinning (RJS) or centrifugal spinning is investigated to evaluate the rheological limitations of polymer solutions and melts to optimal spinnability. The influence of Newtonian or non-Newtonian behavior of the polymer on spinnability is discussed. We observe that highly viscous polymers tend to block the die channels within a rotary jet spinneret and therefore suggest the use of relatively low Newtonian viscosities of between 1 and 10 Pa s for optimal fiber production. Computational fluid dynamics simulations are used in conjunction with experimental data to establish important processing parameters, such as typical shear rates in the device and optimal polymer melt or solution viscosities. A theoretical model for RJS is compared to measured fiber diameters. The comparison shows that although fiber diameters can be estimated very roughly in the case of polymer solutions, the prediction of fiber diameter in the case of polymer melts require further modeling work.
