“…for PP fibres with an MFI of 12.4 g/10 min are 23.80 ± 18.07 μm ( Table 6 ), those produced with an MFI of 127 g/10 min measured 9 ± 8.31 μm ( Table 6 ), which is much smaller. The studies that produced PP fibres through hot melt CS measured an average diameter of 0.5–9.08 μm [20] , [22] , [8] , [23] , [27] , thus our results for the MFI of 127 g/10 min are in this bracket.…”

“…In a previous work from Wongpajan and al. [8] , polypropylene (PP) fibres were produced through an apparatus that works similarly to meltblown. While their PP feedstock melted between 280–350°C, the airflow used to extrude the melt was maintained at 600°C [8] constantly.…”

“…Furthermore, since the emitter wall has several orifices, rotary jet spinning offers higher throughput relative to electrospinning [4]. In fact, rotary jet spinning has been long known in regular life through the cotton candy machine and for this reason, it is also called the Cotton Candy (CC) method [25,26]. Replacing sugar with polymer and tuning the temperature and emitter rpm offers an easy design one can construct from commonly available parts.…”

“…Temperature: Tests on the appropriate range of temperatures were heavily informed by Ref. [26]. Although the transition temperature for PS is T T = 123 − 128 • C and that of PP is T T = 160 − 165 • C, they do not readily flow at these temperatures but merely soften into highly viscous fluids.…”

Face masks in general, and N95 filtering facepiece respirators (FRs) that protect against SARS-Cov-2 virion in particular, have become scarce during the ongoing COVID-19 global pandemic. This work presents practical design principles for the fabrication of electrocharged filtration layers employed in N95 FRs using commonly available materials and easily replicable methods. The input polymer is polypropylene or polystyrene, and can include discarded plastic containers of these materials, and the fabrication set-up is based on the cotton candy (CC) principle. The primary parameters underlying the CC principle are translated to simple design rules that allow anyone to construct their own fabrication system from common parts, or employ a commercial CC machine with minimal modifications. Finally, basic characterization results for structural and filtration properties of electrocharged fabrics made using the CC principle are detailed.

In the light of marine microplastic pollution and mounting environmental degradation, this research proposes biodegradable poly(lactic acid) (PLA) nonwoven fabric produced by novel melt jet spinning technology under various process conditions. In the study, the die temperature was varied at 210, 230, and 250 °C and the die-to-collector distance was varied between 30, 60, 90, and 120 cm. The performance metrics included fiber diameter, fiber crystallinity, fabric weight, air permeability, and contact angle. The results revealed that the optimal die temperature was 250 °C. At 250 °C, the fibers were of fine size with high crystallinity, independent of collector distances. Specifically, the die-to-collector distance, given the optimal die temperature, had negligible effect on the fiber diameter and crystallinity. On the other hand, the collector distance played a role in the nonwoven fabric characteristics. The collector distance was positively correlated with the elongation at break and air permeability but inversely correlated with the fabric density and tensile strength. The fabric contact angles were found to be in the range of 124–130 °, indicating the hydrophobicity of PLA nonwoven fabric. Essentially, the novelty of this research lies in the use of biodegradable PLA polymers, as opposed to conventional petroleum-based non-biodegradable polymers; and melt jet spinning technology to realize fine microfibers (1–10 µm).
