Streszczenie:

Electrospinning is direct process to produce polymer fibre with high specific surface area ratio. Apart from polymer fibre producing; electrospinning also can produce a continuous nano size of polymer fibre, which the benefit of this process is the fibre can be produced straight away with lower cost than conventional melt spinning process. Recently, successful attempts have been made to produce polymer fibre by adjusting the parameters of electrospinning such as the collector distance, needle size, polymer concentration voltage applied. From this study, the electrospun fibre was distributed randomly on collector plate surface. The diameter of the fibre produced increase as the polymer concentration was increased. The fibre distribution does not affected by the differ polymer concentrations electrospun, but there were polymer beads formed at the low polymer concentration in solvents. The fiber elongation value is the highest by polymer fiber of 9 wt % while the highest strength is by polymer fiber of 7 wt %. The polymer fibre with low concentration consequently showed the brittle characteristic.

Streszczenie:

Polymeric materials were evaluated with regard to their spinnability and respective fibre diameters. A modified single fibre spinning device was firstly used to derive a novel generalised model, utilising process parameters (die diameter, throughput, and stretching relevant take-up pressures) and material properties (zero shear viscosity) to predict the diameter of polymeric fibres on the basis of four different polymers. Further evaluation of the resulting power law dependence was conducted on filaments produced via conventional melt spinning and meltblown processes. Fibres produced on the pilot machines showed close agreement with the model equation with only the need to adjust an easily calculable device dependent factor. The outcome of the presented work is a user-friendly model of high practical relevance, which can be used to predict the diameter of amorphous and semicrystalline polymeric fibres, independent of material and machine used with sufficient accuracy for fast estimations.

Streszczenie:

A roller electrospinning system was used to produce nanofibres by using different solution systems. Although the process of electrospinning has been known for over half a century, knowledge about spinning behaviour is still lacking. In this work, we investigated the effects of salt for two solution systems on spinning performance, fibre diameter, and web structure. Polyurethane (PU) and polyethylene oxide (PEO) were used as polymer, and tetraethylammonium bromide and lithium chloride were used as salt. Both polymer and salt concentrations had a noteworthy influence on the spinning performance, morphology, and diameter of the nanofibres. Results indicated that adding salt increased the spinnability of PU. Salt created complex bonding with dimethylformamide solvent and PU polymer. Salt added to PEO solution decreased the spinning performance of fibres while creating thin nanofibres, as explained by the leaky dielectric model.

Abstract The aim of the study was to determine the rheological properties of solutions of two types of sodium alginate in water. Rheological studies were carried out to determine the rheological properties of the spinning solutions. Polymer solutions of different concentrations were obtained. Based on the preliminary research of the concentrations of solutions, the proper n and k parameters were selected in order to obtain fibre by wet spinning from solution method. For selected concentrations of polymer solutions, the calcium alginate fibres were obtained.

Streszczenie:

The extensional flow of a polymeric fluid during the fibre spinning process is studied for finite-amplitude stability behaviour. The spinning flow is assumed to be inertialess and isothermal. The nonlinear extensional rheology of the polymer is described with the help of the eXtended Pom-Pom (XXP) model, which is known to exhibit a significant strain hardening effect necessary for fibre spinning applications. The linear stability analysis predicts an instability known as draw resonance when the draw ratio, $\mathit{DR}$, defined as the ratio of the velocities at the two ends of the fibre in the air gap, exceeds a certain critical value, $\mathit{DR}_{c}$. The critical draw ratio $\mathit{DR}_{c}$ depends on the fluid elasticity represented by the Deborah number, $\mathit{De}={\it\lambda}v_{0}/L$, the ratio of the polymer relaxation time to the flow time scale, thus constructing a stability diagram in the $\mathit{DR}_{c}$–$\mathit{De}$ plane. Here, ${\it\lambda}$ is the characteristic relaxation time of the polymer, $v_{0}$ is the extrudate velocity through the die exit and $L$ is the length of the air gap for the spinning flow. In the present study, we carry out a weakly nonlinear stability analysis to examine the dynamics of the disturbance amplitude in the vicinity of the transition point. The analysis reveals the nature of the bifurcation at the transition point and constructs a finite-amplitude manifold providing insight into the draw resonance phenomena. The effect of the fluid elasticity on the nature of the bifurcation and the finite-amplitude branch is examined, and the findings are correlated to the extensional rheological behaviour of the polymer fluid. For flows at small Deborah number, the Landau constant, which captures the role of nonlinearities, is found to be negative, indicating supercritical Hopf bifurcation at the transition point. In the linearly unstable region, the equilibrium amplitude of the disturbance is estimated and shows a limit cycle behaviour. As the fluid elasticity is increased, initially the equilibrium amplitude is found to decrease below its Newtonian value, reaching the lowest value for $\mathit{De}$ when the strain hardening effect is maximum. With further increase in elasticity, the material undergoes strain softening behaviour which leads to an increase in the equilibrium amplitude of the oscillations in the fibre cross-section area, indicating a destabilizing effect of elasticity in this regime. Interestingly, at a certain high Deborah number, the bifurcation crosses over from supercritical to subcritical nature. In the subcritical regime, a threshold amplitude branch is constructed from the amplitude equation.

Streszczenie:

Alginate microfibres were fabricated by a simple microfluidic spinning device consisting of a coaxial flow. The inner profile and spinnability of polymer were analysed by rheology study, including the analysis of viscosity, storage modulus and loss modulus. The effect of spinning parameters on the morphological structure of fibres was studied by SEM, while the crystal structure and chemical group were characterized by FTIR and XRD, respectively. Furthermore, the width and depth of grooves on the fibres was investigated by AFM image analysis and the formation mechanism of grooves was finally analysed. It was illustrated that the fibre diameter increased with an increase in the core flow rate, whereas on the contrary of sheath flow rate. Fibre diameter exhibited an increasing tendency as the concentration of alginate solution increased, and the minimum spinning concentration of alginate solution was 1% with the finest diameter being around 25 µm. Importantly, the grooved structure was obtained by adjusting the concentration of solutions and flow rates, the depth of groove increased from 278.37 ± 2.23 µm to 727.52 ± 3.52 µm as the concentration varied from 1 to 2%. Alginate fibres, with topological structure, are candidates for wound dressing or the engineering tissue scaffolds.

For the stability of composite fibre spinning, the difference in and distribution of the polymer melt velocity during the spinning are among the factors of importance. Based on the basic equation for the control of composite spinning dynamics, boundary conditions are identified and reported in this paper. A mathematical model for the symmetric and asymmetric distribution of the melt flow velocity in the microhole of the spinneret of the composite spinning assembly was developed. The accuracy of the mathematical model was also ascertained. It gives a theoretical basis for the designing of a composite spinning assembly.

Streszczenie:

Fibres show promising applications such as textiles, filtration, sensing and tissue engineering. In this study, an infusion gyration system to produce polymer micro and nano fibres with functions was introduced. By using this method, functional fibres can be formed from polymer solutions mixed with other functional materials. PEO or PVA water solution was used for making the spinning solutions. The fluorescence protein bound with gold nanoparticles was carried by the PEO water solution, from which the fibres assembled with protein were successfully generated through infusion gyration. A mixed molecular weight PVA combined water solution mixed with processed magnetic nanoparticles achieved fabrication of magnetically controllable fibres have the potential for drug release and its demonstration test showed a positive result. This spinning system provides control of the polymer solution flow rate during spinning which affects the fibre morphology such as average diameter and size distribution. The relationship between the spinning parameters and the product properties was studied for better understanding of the method. The analysis of infusion gyration and its fibre forming process was carried out. The fibres were characterised using several methods, such as optical microscopy, SEM, FTIR and UV-Vis, to establish the potential of infusion gyration and to confirm the functions of final fibre product. The infusion gyration system provides a simple micro and nano scale assembly approach to integrate different protein functionalities into nanofibres with potential applications. Magnetic PVA nanofibres are promising for drug delivery.

Putting on or taking off clothes helps the body to stay within the comfortable temperature range (toavoid shivering or sweating) at different activity levels and ambient conditions. Clothes with built-inthermo-regulating properties would mean maintained comfort without putting on or taking off clothesthat frequently. Integration of phase change materials (PCMs) in clothes is one way of achievingthermo-regulating properties. When the body temperature goes up, the PCM melts and absorbs theheat from the body in the form of latent heat (cooling effect). When the temperature drops, the PCMcrystallizes and the stored heat is released again (warming effect).Research on thermo regulating fibres of the bi-component type containing PCM in the core has beenconducted at Swerea IVF in Mölndal, Sweden, for some time. It has been found that high molecularweight HDPE is a suitable viscosity modifier for hydrocarbon waxes used as PCM. The preparation ofcore materials has so far been done in a batch wise fashion in the way that molten wax has beensoaked into pelletized HDPE at around 180°C during prolonged times followed by melt compoundingin a Brabender batch kneader (0.3 kg per batch). Besides being very impractical for larger productionvolumes the method involves long residence times at high temperatures which may induce thermaldegradation reactions. The objective of the present diploma (master’s thesis) work was to develop acontinuous mixing method to produce PCM/HDPE blends and to test the resulting material in bicomponentfibers with a Nylon (PA6) sheath and to characterize the resulting fiber properties in termsof strength and latent heat.It was proven possible to compound HDPE with large amounts (70%) of octadecane (PCM) on aBrabender twin screw extruder. HDPE was metered to the extruder hoper by means of a screw feederand wax was continuously fed to the hoper in the liquid state by means of a heated membrane pump.To facilitate mixing HDPE in form of powder instead of pellets was used. The extruded threads weresolidified in a water bath followed by granulation. Bi-component fibers were successfully producedfrom such materials. Fibers containing 15 to 42% Octadecane were produced showing heat of fusionsin the range 26 to 86 J/g and tenacities in the range 33 to 16 cN/tex. The heat of fusion of the fiberscompares favorable with existing commercial products showing values in the range 5-15 J/g (acrylicand cellulosic fibres containing microencapsulated hydrocarbon waxes). The peak melting point ofoctadecane measured by DSC was found to be depressed some 4-5°C in the fibers compared to pureoctadecane (28°C). Such a melting point depression is important to consider when choosing type ofhydrocarbon wax.

Streszczenie:

The production of long, thin polymeric fibers is a main objective of the textile industry. Melt-spinning is a particularly simple and effective technique. In this work, we shall discuss the equations of melt-spinning in viscous and viscoelastic flow. These quasilinear hyperbolic equations model the uniaxial extension of a fluid thread before its solidification. We will address the following topics: first we shall prove existence, uniqueness, and regularity of solutions. Our solution strategy will be developed in detail for the viscous case. For non-Newtonian and isothermal flows, we shall outline the general ideas. Our solution technique consists of energy estimates and fixed-point arguments in appropriate Banach spaces. The existence result for a simple transport equation is the key to understanding the quasilinear case. The second issue of this exposition will be the stability of the unforced frost line formation. We will give a rigorous justification that, in the viscous regime, the linearized equations obey the ``Principle of Linear Stability''. As a consequence, we are allowed to relate the stability of the associated strongly continuous semigroup to the numerical resolution of the spectrum of its generator. By using a spectral collocation method, we shall derive numerical results on the eigenvalue distribution, thereby confirming prior results on the stability of the steady-state solution.

Streszczenie:

Poly(ethylene terephthalate) (PET), poly(trimethylene terephthalate) (PTT), poly(ethylene isophthalate) (PEI), and poly(trimethylene isophthalate) (PTI) were synthesized in a Parr reactor and melt-spun. Thermal and physical properties of the as-synthesized polymers and melt-spun fibers were determined. As-synthesized PEI and PTI were amorphous polymers and did not show any melting peaks by DSC analysis. All the polymers were thermally stable (TGA analysis). Amorphous films were made by a melt-press method with PET and PEI for determination of CO2 gas barrier properties. PEI, which has the meta-linkage of ester groups on the phenyl ring, had much lower CO2 gas permeability around one tenth that of PET, which has the para-linkage of ester groups on the phenyl ring. This is because in PET the phenyl rings are substituted in the para (1,4) positions, which allows for their facile flipping, effectively permitting gases to pass through. However, the meta-substituted phenyl rings in PEI do not permit such ring flipping, and thus PEI may be more suitable for barrier applications. The coalesced PEI was prepared from the inclusion compound of PEI with ?×-cyclodextrin. The coalesced PEI may have retained partially highly extended and parallel chains from the narrow channels of the inclusion compound, resulting in better/tighter packing among the PEI chains and exhibited a higher glass-transition temperature. Cyclic oligoesters of PET, PTT, PEI, and PTI were prepared by cyclo-depolymerization of these polyesters. The cyclic oligoesters were mixtures of different sized cyclic oligomers. PET cyclic oligomers showed four melting peaks at 59, 122, 194, and 276 o C. The cyclic oligomers of PTT, PEI, and PTI showed single melting peaks at 241, 335o C and 147o C, respectively. The cyclic oligoesters could be converted to linear polyesters by ring-opening polymerization. PTT was also prepared by ring-opening polymerization of its cyclic dimer obtained as a by-product in the conventional manufacturing plant. Antimony, tin, and titanium catalysts were used with various concentrations. The highest molecular weight, 40,000 g/mol was obtained when 0.25 mol% of titanium(IV) butoxide was used.

Streszczenie:

Man-made fibres are produced from chemical substances known as synthetic fibres. Synthetic fibre or a synthetic polymer made from molecules of monomer joined together to form long chains, is also known as an artificial fibre. Besides polymerbased synthetic fibres, other types of fibres that have special commercial applications and importance. These include the fibers made of carbon, glass,metal and ceramics. Polymer-based synthetic fibres are produced by various processes such as melt spinning, dry spinning and wet spinning.The melt spinning technique is used to produce polymers such as polyethene, polyetheneterephthalate, cellulose triacetate, polyvinyl chloride, nylon, etc. Cellulose acetate, cellulose triacetate, acrylic, modacrylic, polyvinyl chloride and aromatic nylon are artificial fibres manufactured by dry-spinning. In contrast, the wet spinning process is used for aromatic nylon, polyvinyl chloride fibres, acrylic, modacrylic and viscose rayon from regenerated cellulose.The importance and usefulness of synthetic fibres are because they have enhanced properties compared to natural fibres, which come from plants or animals. Still, each type is valued for different reasons.

Streszczenie:

Fiber spinning is one of the oldest polymer processing operations that have contributed significantly to our society, especially after the commercialization of polyamide (nylon) synthetic fibers in the 1940s by DuPont Company. Subsequent commercialization of poly(ethylene terephthalate) (PET) and polyacrylonitrile fibers in the 1950s made the synthetic fiber industry very prosperous. For a given fiber-forming polymer, different spinning techniques can produce fibers possessing markedly different physical and/or mechanical properties. Thus, the fiber industry made continuous efforts through the 1960s and 1970s to modify existing processes and develop new ones. One very important breakthrough from such efforts emerged in the late 1970s, enabling one to melt spin at exceedingly high take-up speeds, widely known today as “high-speed melt spinning.” While the fiber manufacturers carefully guarded their spinning techniques, the commercial developments were documented in numerous patents. Beginning in the early 1960s, some fundamental studies on fiber spinning were reported in the open literature, and they are summarized in the three-volume monograph edited by Mark et al. (1967). An understanding of fiber spinning requires knowledge of momentum, energy, and/or mass transport. In addition, knowledge of macromolecular behavior under deformation (i.e., stretching) is also necessary for understanding such complicated problems as molecular orientation under stretching, crystallization kinetics under cooling, and fiber morphology as affected by spinning conditions. In the late 1950s, and the early 1960s, Ziabicki and coworkers (Ziabicki 1959, 1961; Ziabicki and Kedzierska 1959, 1960a, 1960b, 1962a, 1962b) made seminal contributions to a fundamental understanding of fiber-spinning processes, and their efforts were summarized in Ziabicki’s monograph (1976a). In the 1970s, a new class of synthetic fibers, known as “high-modulus wholly aromatic fibers,” was developed (Bair and Morgan 1972; Daniels et al. 1971; Frazer 1972; Kwolek 1971; Logullo 1971; Morgan et al. 1974) and subsequently commercialized with the trade name of Kevlar by DuPont (Kwolek 1971). The chemical structure of such synthetic fibers consists of rigid rodlike molecules that orient easily along the stretching direction during spinning, giving rise to high modulus in the spun fibers. The chemical structure and mechanical properties of the wholly aromatic fibers are well documented in the monograph edited by Black and Preston (1973).

Nanofibers are widely used in various fields, including water filtration. In the development of nanofibers as water filtration, a mixture of carbon in a polymer solution is often used. Nanofibers can be made by several methods such as multicomponent fiber spinning techniques, melt blowing, electrospinning. Electrospinning is currently a simple development method but can produce nanofibers with a small fiber diameter, it is easy to develop and many parameters can be controlled. Parameters that affect the results of the nanofibers that are formed include flow rate or syringe pump flow rate and high voltage dc high voltage. Various types of nanofibers can be produced from various types of polymers, both natural polymers and synthetic polymers. Generally, because they have properties and characteristics such as high surface area, small pore size, and the possibility to be developed in various applications. Therefore, this chapter discusses the electrospinning of carbon nanofibers using PVA polymer.

Polymer nanofibers are attractive in many engineering and medical applications because of its distinctive mechanical, chemical, and electrical properties typically evident in nanomaterials. Some applications are liquid & particle filters, composites, surgical masks, sensors. We propose a fibre fabrication method that can produce continuous polymer nanofibres with submicron cross-section. This technique can spin fibres from precursor rheologies that would be considered “unspinnable” by any other current method. As such, this technique may allow the fabrication of novel fibre structures, assist in the fabrication of nanofibers from new materials, and allow the use of novel chemical routes in fibre spinning.

Abstract Carbon nanoparticles-based polymer composites have wide applications across different fields for their unique functional properties, durability, and chemical stability. When combining nanoparticle morphologies with micro- or macro-scale morphologies, the hierarchal structure often would greatly enhance the composites’ functionalities. Here in this work, a thermoplastic polyurethane (TPU) and graphene nanoplatelets (GnPs) based multilayered fiber is fabricated through the combination of dry-jet-wet spinning, based on an in-house designed spinneret which accommodates three layers spinning solution, and hot isostatic pressing (HIP), at 220 °C. The multilayered spinneret enables the spinnability of a high GnPs loaded spinning dope, highly elastic, with great mechanical strength, elongation, and flexibility. The HIP process resulted in superior electrical properties as well as a newly emerged fourth hollow layer. Together, such a scalable fabrication method promotes a piezoresistive sensor that is sensitive to uniaxial strain and radial air pressure. The hollow fiber is characterized based on surface morphologies, layer formation, percolation threshold, piezoresistive gauge factor, mechanical stability and reversibility, and air-pressure sensitivity and reversibility. Such facile fabrication methods and unique structures have combined the mechanically robust outer shell with a highly conductive middle sensing layer for a new sensor with great potentials in wearable, robotics, biomedical, and other areas.

Abstract One of the challenges to multimaterial multifunctional composite fibers is their scalability during the fabrication process. Additive manufacturing is a cost-effective tooling solution for fast prototyping fiber spinning spinnerets. This work demonstrates a laser powder bed fusion-based tri-axial spinneret that could accommodate three different materials as inner, middle, and outer layers. In the first work, continuous graphene nanoplatelets (GnPs) channel was embedded between core polymer and sheath polymer layers to simultaneously achieve electrical conductivity and high mechanical properties. This multimateiral, multichannel system is too expensive with conventional manufacturing. Our 3D printed spinneret will generate shear stress during the polymer drawing process, resulting in thinning and alignment of the two-dimensional (2D) GnPs. Similarly, in the second research, a multilayered chemiresistor for volatile organic compounds (VOCs) was fabricated in a single step. Each layer played a significant role in the overall sensor functionalities. For instance, (i) the hollow core supported inline gas transportation, (ii) the porous polymer inner layer assisted VOC diffusion, (iii) the middle electrical conductive layer responded to VOCs types and concentrations, and (iv) the outer mechanically stable layer secured sensor’s physical stability.

Ultrahigh molecular weight polyethylene (UHMWPE) fiber blends with Nylon-6 and reinforced with single-walled carbon nanotubes (SWCNT) were produced using a solution spinning process. Polyethylene-graft-Maleic Anhydride (PE-g-MAH) was used as a compatibilizer to enhance the interfacial bonding between the polymer phases. The loading of Nylon-6, MAH, and SWCNTs with respect to UHMWPE was 20 wt.%, 10 wt.% and 2 wt.% respectively. The development of morphological characteristics due to the inclusion of a compatibilizer in an immiscible hybrid polymer nanocomposite fiber is hereby discussed. Characterization studies of the hybrid fibers were performed using scanning electron microscopy (SEM), Energy-dispersive X-Ray Spectroscopy (EDS) and Fourier-transform infrared spectroscopy (FTIR).

Streszczenie:

Electrospinning is a viable technique that spins fibers at different diameters starting from 3 nm to several micron meters. This technique allows the fabrication of random and aligned fibers of diverse structures, such as ribbon or cylindrical shapes. In this work, the spinning solution is prepared by dissolving recycled polystyrene and the mixture of polystyrene and polyvinyl chloride along with carbon nanotubes in dimethyl acetamide (DMAc). The dispersions were then electrospun at various DC voltage, pump speed, concentration and distance. The general morphology of the fibers has been studied by scanning electron microscopy (SEM). The test results confirmed that fiber diameter and surface roughness were increased by increasing the CNTs, which may be because of the viscosity increase of the spinning solution. Addition of carbon nanotubes in the polymer solution also improves the thermal and electrical conductivity, as well as toughness, stiffness and other properties.
