Poly(ethylene-co-vinyl alcohol) (EVOH) nanofibers with average diameter of 260 nm were initially fabricated through the melt-blending extrusion of immiscible blends. The resulting films obtained by layer deposition technology were then functionalized by in situ oxidative polymerization of pyrrole monomer in hydrochloric acid solution for hexavalent chromium [Cr(VI)] adsorption from water. Scanning electron microscopy and Fourier-transform infrared spectroscopy were used to characterize the morphology and structure of functionalized nanofiber membranes. Adsorption experiments were conducted to test the effects of solution pH, dose of adsorbents, water temperature, adsorption contact time, and initial concentration of Cr(VI) and to determine the Cr(VI) adsorption mechanism. The experimental results denoted that the adsorption process was endothermic, spontaneous, and highly pH dependent, and the kinetics data fitted well with a pseudo-second-order model. The adsorption equilibrium time was less than 100 min, and the maximum adsorption capacities were 90.74 mg/g from the adsorption kinetics study. The adsorption isotherm data followed the Langmuir isothermal model. Desorption results exhibited excellent reusability of the membrane for Cr(VI) adsorption.

“…According to the literature survey, researches with respect to PBT are mainly focused on nonwoven production, particularly for filtration purposes [5][6][7][8][9][10][11][12][13][14][15]. Besides, an artificial neural network model was developed to predict the seam strength and elongation at break values and cotton, core-spun, and PBT sewing yarns have been used for experimental.…”

Owing to growing demand for comfortable clothes, elastane filament yarns are being used in fabrics for several garments. In this study, core spun yarns were produced with cotton fibres and PBT/elastane filament yarns (cotton as sheath material, PBT yarn and elastane as core yarns). Twill woven (1/3 Z) fabrics were produced by using core spun yarns (30 tex) and cotton yarns (30 tex) as weft, and 100% cotton yarn (59 tex) as warp yarns. The fabrics consisting of PBT were washed at 100°C for 30 minutes to gain the elasticity. The woven fabrics’ weight, thickness, elongation, permanent elongation, dimensional stability, air permeability, thermal conductivity, thermal absorptivity characteristics were tested and statistically evaluated. According to the results, the fabrics containing PBT and elastane filaments had similar elongation and shrinkage values. PBT filament yarns have a great potential to produce lightweight elastic fabrics.

“…Besides the electrospinning, there are various industrial feasible melt‐processing technologies for producing submicro‐ and nanofibers. These typically include melt‐blowing, conventional melt‐spinning followed by laser supersonic drawing, and sea‐island melt‐spinning . The former two are usually performed with a single polymer and the latter with at least two partially miscible or immiscible polymers.…”

Poly(glycolic acid) Nanofibers via Sea‐Island Melt‐Spinning

Poly(glycolic acid) (PGA) nanofibers are prepared via the high‐speed sea‐island melt‐spinning process for the first time. Poly(l‐lactide) (PLLA) is chosen as the matrix (the “sea” phase) because of its superior spinnability and compatibility with PGA. The process includes melt‐spinning of PLLA/PGA blends at 1.0–2.5 km min−1, hot‐drawing of the as‐spun blend fibers (optional), and dissolving the PLLA phase in chloroform. At an optimal blend ratio, the process is readily conducted, producing ultrafine, uniform, and well‐aligned PGA nanofibers with high degrees of molecular orientation. Studies on morphology evolution of the blends reveal that the PGA phase presents initially as microgranules in the melt blends, breaks into nanogranules in the extruded filaments, and eventually deforms into nanofibers in the as‐spun and drawn fibers. The nanofibers show nearly constant diameters independent of take‐up speed, pointing to phase compatibility dominated mechanism which can be used to establish a viable and flexible production process.
