“…43,55 Thus, these outcomes were predictable regarding the mixture law. 56 In addition, Lin et al 57 reported that incorporating the second component could prevent the formation of the β-crystal structures of PP. This can be because of the suitable mechanical behavior of the β-crystal structures of isotactic PP.…”

An environmentally friendly free-carrier technique was used to prepare poly propylene/poly(trimethylene terephthalate) (PP/PTT) blend fibers. As PTT loading increased, its average diameter enhanced, and its distribution narrowed. In addition, the results of mechanical properties demonstrated that incorporating PTT into the PP matrix led to a decrease in tenacity and elongation-at-break. The more the PTT content, the less the tenacity and the elongation-at-break. Moreover, the crystallinity of PP enhanced by about 12% when 20 wt.% PTT was incorporated while melting and crystallization temperatures did not change remarkably. The molten blends indicated almost a Newtonian behavior. On the other hand, the storage modulus enhanced almost linearly in the frequency range of 1–1000 1/sec for all samples. Also, approximately 60% improvement in dyeability and 10% progress in resiliency behavior were observed. The dye uptake ability of samples was improved with the addition of PTT. In addition, the washing and light fastness of the blends were admissible for textile fibers. Generally, blends with PTT content less than 20 wt.% exhibited better physical and mechanical properties, especially resiliency behavior. Therefore, PP/PTT blend fibers are promising candidates for use in textiles in the coming years.

The deformation behavior and hydrodynamic stability of a three-dimensional Newtonian single-core compound droplet during flow in a channel with sudden contraction were studied by numerical modeling. This research was motivated by the quest for conditions of the steady transition of a compound droplet into a composite microfiber, whose core is stretched as much as the shell. With this aim, the dynamics and morphology evolution of the compound droplet were analyzed in detail as functions of capillary number, core-to-shell relative viscosities, interfacial tensions, and the relative initial core radius. It was found that the effective elongation of the core occurs either with a significant increase in the shell viscosity relative to the ambient fluid or with a decrease in the core viscosity with respect to the shell. In this case, as the composite droplet advances into the narrowing zone of the canal, it continues to stretch, becoming a bullet-shaped composite microfiber. A new mechanism of disintegration of the compound droplet was revealed, which is caused by the core destabilizing effect and manifests itself either with an increase in the relative core/shell interfacial tension or the relative core viscosity.
