Poly(vinylidene fluoride) (PVDF) fibers with two molecular weights were prepared via electrospinning process. In this process, the concentration of spinning depended drastically on the gelation process. Also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (SENA). Proof of this incompatibility was explained by the properties of PVDF a...

Biomass-derived biodegradable fibers have attracted considerable attention as sustainable alternatives to petroleum-derived non-biodegradable synthetic fibers. Curdlan, a linear β-1,3-glucan, is promising renewable resource that exhibits unique physicochemical properties owing its triple-helical crystalline structure. The regenerated of curdlan can be fabricated by wet spinning; these exhibit e...

Smaller fibers are welcome in many applications due to larger surface area, but there is a threshold for smallest fixed spinning system. In order further improve hierarchical structure considered this paper using electrospinning. A bi-solvent system used our experiment fast solvent evaporation. Unsmooth nanofibers obtained, and the formation mechanism elucidated.

The superior mechanical properties of carbon nanotubes (CNTs) mean they have been regarded as a new material with the potential to revolutionize and enable many advanced technologies. CNTs have extremely high tensile strength ( 150 GPa), high modulus ( 1 TPa), large aspect ratio, low density, good chemical and environmental stability, and high thermal and electrical conductivity. These superior...

The strength of spinning products formed by the wet finning method is determined adhesion forces that arise between contacting fibers. To predict yarn and roving obtained in this way, it necessary to know number fiber contacts cross section product. Studies distribution fibers linen have been carried out a for determining has proposed. initial data are digitized images sections using digital mi...

Spinning of cellulose acetate (CA) with the additive polyvinylpyrrolidone (PVP) in N-methyl-2-pyrrolidone (NMP) solvent under different conditions was investigated. The spinning parameters of air gap, bore fluid composition, flow rate of bore fluid, and quench bath temperature were optimized based on the orthogonal experiment design (OED) method and multivariate analysis. FTIR and scanning elec...

Ionic liquid solutions of cellulose or dopes can be spun into Lyocell-type textile fibers by dry-jet wet spinning. An extruded dope is drawn over an air gap into water, where the water hydrates the ionic liquid and cellulose is regenerated. Spinnability studies have concentrated on the deformation and failure modes in the air gap and thus the rheology of the unhydrated spinning dope. Herein, a ...

Pd doped WO3 fibers were synthesized by electro-spinning. The sol gel method was employed to prepare peroxopolytungstic acid (P-PTA). Palladium chloride and Polyvinyl pyrrolidone (PVP) was dissolved in the sol Pd:WO3 = 10% molar ratio. The prepared sol was loaded into a syringe connected to a high voltage of 18.3 kV and electrospun fibers were collected on the alumina substrates. Scanning elect...

Hybrid sols of poly (vinyl alcohol) (PVA)/Silicon oxide-titanium oxide (SiO2-TiO2) were prepared with tetraethoxylsilane and tetrabutyl titanate as precursor using Sol-Gel method. PVA/SiO2-TiO2 hybrid fibers were prepared by drawing from the hybrid sols using dip-coating method and aging treatment. The spinnability of hybrid sols was investigated. Spinnable time (t) and spinnable length (l) of ...

Natural fibers have been used as an alternative to synthetic ones for their greener character; banana fibers have the advantage of coming from an agricultural residue. Fibers have been extracted by mechanical means from banana tree pseudostems, as a strategy to valorize banana crops residues. To increase the mechanical properties of the composite, technical textiles can be used as reinforcement...
