Resumen
Natural plant extracts without non-toxic side effect and the relevant products are gaining popularity, and make natural medicines one option of health care. This study combines polypropylene (PP) fibers, high-absorption polyacrylate (HPA) fibers with weight ratios of 100/0, 90/10, and 80/20 wt % with a nonwoven manufacturing process to form PP/HPA nonwoven fabrics, after which the fabrics are immersed in a Bletilla striata (BS) extract, and then dried, yielding functional PP/HPA/BS nonwoven fabric. Stereomicroscopic observation, tensile strength test, tear strength test, and air permeability test are performed on the sample to evaluate the difference in mechanical properties before and after the immersion. In vitro test evaluates the biocompatibility of BC extract. The experimental results show that functional PP/HPA/BS nonwoven fabrics have optimal mechanical properties and an optimal content of 32.2 % BS extract when the nonwoven fabrics are made with an 80:20 ratio.

Resumen
In order to realize organ-on-a-chip as an effective tool for regenerative medicine and drug development, tissue-mimic cell culture methods which promote liver-specific function for long period have been developed. We have previously demonstrated that coculture of hepatocyte spheroids on fibroblasts using micropatterned substrate improved the hepatic functions due to the heterotypic cell–cell interactions and paracrine signaling from each other. In addition, hepatocyte function cultured as monolayer was also promoted in separately coculture with fibroblasts cultured as monolayer, and it is more improved in separately coculture with fibroblasts in 3D silica nonwoven fabrics. In this study, separately coculture of hepatocyte spheroids with fibroblasts cultured on 3D silica nonwoven fabrics was estimated for further improvement of hepatocyte functions. The hepatic function cocultured with fibroblast was more promoted than mono spheroids culture. The functional enhancement was significantly most improved in separately coculture with fibroblast in 3D silica nonwoven fabrics. Thus, these results were suggested that 3D culture of fibroblasts in 3D silica nonwoven fabrics increased the heterotypic secretion of paracrine factors, and it is essential for improved hepatic performance.

Resumen
Honeycomb structures are widely used in various engineering fields, including construction, the auto industry, packaging, the aerospace industry, medicine, and sports. The hexagon cells generate excellent structures and reduce material waste. Honeycomb structures have very good mechanical properties and are low cost. Nonwoven fabric is widely used in many applications because the manufacturing process for nonwoven fabric is easy and fast. In this study, Polylactic Acid (PLA) nonwoven fabric and Thermoplastic Polyurethane (TPU) honeycomb air cushion (TPU-HAC) materials were combined in a sandwich structure for impact protection. The PLA fibers and low-melting-point PLA fibers were used as raw materials to create PLA nonwoven fabric. The PLA fibers and low-melting-point PLA fibers were mixed at weight ratios of (10%, 20%, 30%, 40%, 50%). The mixed fibers were processed using needle punching and thermal bonding to create PLA nonwoven fabric. Additionally, the TPU-HACs were layered to generate various thicknesses (2/8/10 mm, 4/6/10 mm, 6/4/10 mm, 8/2/10 mm). The layered TPU-HAC materials was clamped between two PLA nonwoven fabrics to form a sandwich structure. Impact resistance was assessed using a falling- weight impact-resistance machine. Experimental findings indicate that impact resistance of the sandwich structure of the TPU-HAC materials improved when thin TPU-HAC material was placed on the thick TPU-HAC material. This study demonstrates that the sandwich structure of TPU-HAC materials as excellent impact absorption.

Resumen
Insufficient endothelialization of stent grafts tends to cause a problem of thrombosis formation. Because the structure of nanofibers, generally defined as fibers with a diameter below 1 μm, resembles the structure of an extracellular matrix, nanofibers are applied to scaffolds for regenerative medicine. Using nanofibers as the covering material of the stent graft can be expected to solve the problem of the stent graft. Previous studies have shown that a porous scaffold offers better surfaces to anchor and culture endothelial cells than a nonporous scaffold. Therefore, fibers with nanoorder dimples are expected to promote endothelialization. As a method of forming the dimple shape on the surface of the PET fiber, there is a method utilizing a difference in the volatilization rate of the solvent in the high humidity environment in the electrospinning method. For practical application of the stent graft to artificial blood vessels, the mechanical properties of the dimpled PET fiber should be clarified. In this study, the mechanical properties of single nanofibers and nonwoven fabrics of PET fibers with dimples on their surface were evaluated by tensile test. By forming the dimple shape on the fiber surface, the tensile strength of single PET fibers with dimples was 90 % lower than that of single PET fibers with a smooth surface. In the fabrication process of nonwoven fabric, the addition of EG delayed the volatilization of the PET solution, and the fibers adhered to each other. The bonding between the fibers contributed to the tensile strength of the nonwoven fabric.

Resumen
Abstract Due to its excellent biocompatibility, Chitosan is a very promising material for degradable products in biomedical applications. The development of pure chitosan microfibre yarn with defined size and directional alignment has always remained a critical research objective. Only fibres of consistent quality can be manufactured into textile structures, such as nonwovens and knitted or woven fabrics. In an adapted, industrial scale wet spinning process, chitosan fibres can now be manufactured at the Institute of Textile Machinery and High Performance Material Technology at TU Dresden (ITM). The dissolving system, coagulation bath, washing bath and heating/drying were optimised in order to obtain pure chitosan fibres that possess an adequate tenacity. A high polymer concentration of 8.0–8.5% wt. is realised by regulating the dope-container temperature. The mechanical tests show that the fibres present very high average tensile force up to 34.3 N, tenacity up to 24.9 cN/tex and Young’s modulus up to 20.6 GPa, values much stronger than that of the most reported chitosan fibres. The fibres were processed into 3D nonwoven structures and stable knitted and woven textile fabrics. The mechanical properties of the fibres and fabrics enable its usage as textile scaffolds in regenerative medicine. Due to the osteoconductive properties of chitosan, promising fields of application include cartilage and bone tissue engineering.

Nonwoven fabrics are sheet structures created by bonding or interlocking a web (network) of fibers through mechanical, thermal or chemical processes. In general, the mechanical response of nonwoven fabrics exhibits two major characteristics. First, the mechanical response can vary significantly when the fabric is loaded along different directions, depending on the existence of a preferential orientation in the fiber arrangement and/or in the pattern of inter-fiber bonding/entanglement. Second, the mechanisms of deformation include elastic and inelastic components, accompanied by an irrecoverable evolution of the texture of the fiber network. In this work, we propose a three-dimensional, large strain continuum model for the constitutive behavior of nonwoven fabrics that accounts for the fiber network characteristics responsible for its anisotropic behavior, and captures the effects of deformation mechanisms at the micro-scale (fiber and bonds/entanglement) level. The model consists of two constitutive components: a nonlinear elastic component representing the resistances to recoverable deformation mechanisms, and a non-linear inelastic component representing the resistances to irrecoverable deformation and texture evolution. For nonwoven fabrics in which the anisotropy of fiber orientation is combined with random entanglement processes, we propose to capture the combined effects of fibers and junctions orientation distributions using a single tensorial representation of the network anisotropy (fabric ellipsoid). An orthotropic elastic constitutive model for the elastic response of nonwoven fabrics is then formulated based on this structural measure and deformation mechanisms of the network structure. The inelastic component of the model is then prescribed in terms of an evolution law for the fabric ellipsoid.
(cont.) A needlepunched web of high strength polyethylene fibers, "Dyneema Fraglight", is selected as the representative material, to be used as a test case to validate the proposed modeling approach. The model is shown to capture the macroscopic nonlinear anisotropic elastic-inelastic response of the fabric in planar deformation, as well as the underlying micromechanical deformation mechanisms, such as fiber stretch, and irrecoverable evolution of fabric texture. The proposed model can be used to predict the mechanical behavior of nonwoven fabrics and can be combined with other continuum models to aid in the design of multi-component structures. In addition, the proposed elastic formulation can be used to model different classes of anisotropic network materials, such as biological tissues, and tissue engineering scaffolds.

Resumen
This study is divided in to two main parts. The first part deals with the optimization of process parameters of needle-punched non-woven fabrics for achieving maximum sound absorption by employing a Box-Behnken factorial design. The influence of fibre type, depth of needle penetration and stroke frequency on sound absorption properties were studied. These parameters were varied at three levels during experimental trials. From multiple regression analysis, it was observed that the depth of needle penetration alone was the most dominant factor among the selected parameters, which was followed by the interaction between depth of needle penetration and stroke frequency. Fibre type was the least dominant parameter affecting sound absorption. A maximum sound absorption coefficient of 47% (0.47) was obtained from the selected parameters. The results showed that for a process such as needle-punching, which is influenced by multiple variables, it is important to also study the interactive effects of process parameters for achieving optimum sound absorption. The second part of the study deals with the effect of type of natural fibre (fineness), and the blending ratio (with PET fibres) on the air permeability of the needle-punched non-woven fabrics and then it proceeds to study the effect of the air-gap, type of natural fibre (fineness) and blending ratio (with PET fibres) on sound absorption of needle-punched non-woven fabrics. These parameters are tested individually and their two way interaction (synergy) effect using ANOVA. The air-gap was varied from 0mm to 25mm with 5mm increments, three natural fibre types were used and all were blended with polyester fibres at three blending ratios for each natural fibre type. The Univariate Tests of Significance shows that all three parameters have a significant effect on sound absorption together with two two-way interactions, with the exception of the Blend Ratio × Air Gap two-way interaction which was not significant. It was found that the sound absorption improves with the increase in the air-gap size up to 15mm after which sound absorption decreased slightly with the further increase in the air-gap up to 25mm.

Resumen
This thesis presents micro-structure models of wet-laid conductive nonwoven fabrics allowing the sheet conductance and shielding effectiveness to be simulated and compared to experimental measurement. Conductive nonwoven fabrics are used within the aerospace and defence industries to provide lightweight, functional electromagnetic enhancement to composite structures. They are materials borne from stochastic processes with anisotropic distributions of fibre and parameters that vary from point to point on the local scale. Monte Carlo models of the material’s micro-structure have been constructed by writing a series of algorithms which pseudo-randomly generate the material’s structure by incorporating key physical parameters such as the density, areal concentration and fibre angle distribution. To define the last of these parameters, a completely new optical method has been developed making use of the Hough Transform. These models have predicted the anisotropic sheet conductance to within 1-2% of experimental values, with an estimated inter-fibre contact resistance of Rj = 8.6kΩ, and a measured geometry factor of Φx = 0.727, Φy = 0.273. Analytic models of the material are derived from first principles enabling the rapid calculation of the sheet conductance, whilst also providing an understanding between the key parametric relationships. The analytic model, Monte Carlo model and experimental measurements are compared and give good correspondence. The micro-structure models are finally applied to a full wave electromagnetic simulation technique and shown to produce close correlation to polarisation specific measurements of the shielding effectiveness. High frequency (up to 200GHz) simulations of lightweight nonwoven structures suggest an eventual fall in the shielding effectiveness, attributed to the material’s sub-wavelength apertures.

Resumen
Thermomechanically bonded spunbond nonwoven fabrics contain discrete bonds that are formed by melted and fused fibers. Through equi-biaxial tensile testing and simultaneous image capture, the mechanical response of individual bonds was studied through loading in the preferential fiber direction, the machine direction, and in the direction that is perpendicular, the cross direction, of the fabric web. Independent biaxial force and displacement data were collected and analyzed, and the maximum force and stiffness of the bonds in the machine and cross directions were found to be statistically different. After scaling the maximum force and stiffness by a relative basis weight parameter, a fiber orientation parameter, and the width of the bond itself, the peak force and stiffness in the machine and cross directions were found to no longer be statistically different. This indicates that basis weight, fiber orientation, and bond size dictate the biaxial mechanical behavior of the bonds. Furthermore, significant fiber debonding was observed in all the bonds tested, effectively suggesting bond disintegration into the individual component fibers during testing. Digital image correlation, using the captured images, was utilized to calculate local and average Eulerian strains of the bond during the initial stages of the test. The strain experienced by the bonds in the machine direction was always positive and increasing as the biaxial load increased. The strain in the cross direction, however, experienced increasing and decreasing strain. Local strain maps revealed the highly inhomogeneous strain response of the bonds under biaxial loading.

Resumen
The importance of the drape properties of fabrics on final garment appearance and fit has been long understood and a great deal of research has been carried out in this area. More recently, nonwoven fabrics have begun to create interest among the apparel and fashion design community. In this study, the conventional method of measuring fabric drape was compared with garment drape measurement using an alternative drape measurement system based on an image analysis technique. Garment drape was investigated using dresses suspended on a mannequin. A garment chosen was a shift dress because of its relatively uncomplicated style and shape. Hydroentangled nonwovens were selected as they show good performance and similarity to conventional fabrics in terms of physical and mechanical properties. A graphical user interface was developed to carry out the image analysis and to calculate drape values identifying and determining 23 drape parameters. A range of fabrics including conventional (knitted, woven) and nonwoven fabrics were compared in terms of FAST properties, drape coefficient and drape values. Some nonwoven fabrics were found to give similar performance to some conventional fabrics and better than others. Subjective assessment of the fabric range was carried out in terms of drape amount and preference. Low agreement was found between individuals with regard to preferred drape amount and high agreement with respect to actual drape amount. Nonwovens were found to be better preferred over some conventional fabrics. Most of the drape values of fabric and garment were found to have poor correlations.

Resumen
Incontinence is a common health problem among the human population, especially females. Although there have been many efforts to develop cures not all sufferers can be fully cured. A way to deal with this large portion of incontinence sufferers is pads. The continuous usage of pads creates some problems, though. The most common cause of these problems is friction between pads and skin. In order to describe friction, David Cottenden developed a mathematical model for describing friction between a conformable sheet and a curved surface. Previous work has already validated the model for strips of nonwoven fabric on rigid convex prisms and low – half angle cones . The aim of this project was to extend the validation to (i) large – half angle rigid cones (whose surfaces approximate to portions of the body); (ii) human volar forearms and (iii) highly compliant cylinders. In the first part of the project I validated the model for an example nonwoven fabric on rigid (Plaster of Paris) cones with half angles of 25°, 35° and 45°. As predicted by the model, the data for all fabric footprints on all cones fell on the same master curve, within experimental error. In the second part of the project, I used the volar forearms of young and older female participants. In this way I had the opportunity to test the model on real human skin (smooth and wrinkled) and different substrates (firm and flaccid tissues) as they varied between young and older subjects. Moreover, I observed the changing geometry of arms during experiments, especially the behaviour of – often wrinkled and flaccid – older arms and see how the model responded. I used strips of five different nonwoven fabrics investigating not only how the substrate affected the model, but also how behaviour varied between fabrics. The agreement between experimental data and model predictions was excellent for all fabrics. In the third part of the project, I used the same five fabrics on compliant cylinders made of soft silicone membrane “skins”. These cylinders helped me investigate how the model responded for extreme deformations (rucking) which were much greater than humans could have tolerated. Again, agreement between experiment and model was remarkably good. In summary, all three blocks of experimental work provided further validation of Cottenden’s model, increasing confidence that it can be used in future work to understand friction over the curved surfaces of the body and help develop products kinder to the skin.

Resumen
The aim of this research was to establish the optimum processing conditions and parameters for producing nonwoven fabrics best suited for application in disposable and protective wear for surgical gowns, drapes and laboratory coats. Carded and crosslapped webs, of three basic weights (80, 120, and 150g/m2), from greige (unscoured and unbleached) cotton, viscose and polyester fibres, were hydroentangled, using three different waterjet pressures (60, 100 and 120 bars), on a Fleissner Aquajet hydroentanglement machine. An antibacterial agent (Ruco-Coat FC 9005) and a fluorochemical water repellent agent (Ruco Bac-AGP), were applied in one bath using the pad-dry-cure technique, to impart both antibacterial and water repellent properties to the fabrics, SEM photomicrographs indicating that the finished polymers were evenly dispersed on the fabric surface. The effect of waterjet pressure, fabric weight and type and treatment on the structure of the nonwoven produced, was evaluated by measuring the relevant characteristics of the fabrics. As expected, there was an interrelationship between fabric weight, thickness, and density, the fabric thickness and mass density increasing with fabric weight. An increase in waterjet pressure decreased the fabric thickness and increased the fabric density. The water repellent and antibacterial treatment increased the fabric weight and thickness. The antimicrobial activity of the fabrics was assessed by determining the percentage reduction in Staphylococcus aureus and Escherichia coli bacteria population. The maximum percent reduction at 24hrs contact time for both bacteria ranged from 99.5 to 99.6 percent for all the fabric types. The standard spray test ratings for the three treated fabrics ranged from 80-90 percent, whereas that of the untreated water repellent fabric was zero, while the contact angles for all the fabric types exceeded 90 degrees, indicating good resistance to wetting. It was found that the tensile strength of the fabric in the cross-machine direction was higher than that in the machine direction, for both the treated and untreated fabrics, with the tensile strengths in both the MD and CD of the treated fabrics were greater than that of the untreated fabrics, the reverse being true for the extension at break. An increase in waterjet pressure increased the tensile strength but decreased the extension at break, for both the treated and untreated fabrics. The finishing treatment decreased the mean pore size of all the fabrics, the mean pore size decreasing with an increase in fabric weight and waterjet pressure. An increase in waterjet pressure and fabric weight decreased the air and water vapour permeability, as did the finishing treatment, although the differences were not always statistically significant. The polyester fabrics had the highest water and air permeability. Hence low weight fabrics of 80 g/m2, which were hydroentangled at low water jet pressures of 60 bars, were suitable for use in this study due to their higher air and water vapour permeability as well as higher pore size distribution. These group of fabrics thus meet the requirements for surgical gowns, drapes, nurses’ uniforms and laboratory coats.

Resumen
This study investigates the extrusion-based additive manufacturing (AM) of silicone 3D contour nonwoven fabrics by liquid rope coiling. Customized contour fabrics are ideal for wearable devices for individualized fit and comfort in contact. The AM using silicone liquid rope coiling can fabricate the porous and 3D contour nonwoven fabrics with enhanced breathability and comfortability. The key challenge in the proposed fabrication is the inability to generate consistent coiling pattern because the nozzle orientation deviates from the surface normal vector. A five-axis machine for silicone extrusion AM of nonwoven fabrics was developed to continuously align the nozzle orientation continuously with the surface normal vector. Three cases of silicone printing by coiling were investigated: 1) 3-axis printing, 2) 4-axis printing with nozzle axis normal to the tangent of the toolpath, and 3) 5-axis printing with nozzle axis parallel to the base surface normal. The coiling pattern and geometrical accuracy of the contour fabrics are studied. Results show that the 5-axis AM can generate the consistent coiling pattern and the desired contour geometry to fabricate the silicone 3D contour nonwoven fabrics.

Resumen
Having a unique structure, nonwoven fabrics possess distinct mechanical properties dissimilar to those of woven fabrics and composites. Anisotropic elastic-plastic mechanical properties of core/sheath type thermally bonded bicomponent fibre nonwoven textiles are computed based on manufacturing parameters and fibre properties. Initially, tensile tests are performed on nonwoven fabrics and their single fibres to assess their mechanical behaviour and obtain input parameters for the developed algorithms. Random orientation of individual fibres is introduced into the model in terms of the orientation distribution function (ODF). An algorithm, based on the Hough transform, is developed to determine the ODF and calculate the structure’s anisotropy. The nonwoven fabric is modelled as an assembly of two regions — bond points and a fibre matrix, having distinct mechanical properties. Bond points are treated as a deformable bicomponent composite material composed of the sheath material of fibres as matrix reinforced with the core material as fibres with random orientation of reinforcement. On the other hand, the fibre matrix is treated as a composite membrane structure having low stiffness in thickness direction. A second algorithm is developed to calculate anisotropic material properties of these regions based on fibre characteristics and manufacturing parameters; it can be used in numerical modelling as well as product development and optimization of nonwovens.

Resumen
Currently, between two and four billion pounds of feathers are produced annually by the poultry processing industry. These feathers are usually converted to animal feed in an attempt to recycle it rather than dispose of them in landfills. However, this method can result in diseases being passed along to the ingestors of this feather meal. Until recently there was no method of removing the quill from feather, but a method of effectively stripping the feather fibers from the quill without damaging the fibers has been patented, and as a result research is being conducted to determine uses for these fibers. Current research has focused on creating nonwoven latex bonded fabrics containing turkey feather fibers for utilization as erosion control fabrics. These fabrics have been compared with currently available erosion control fabrics to determine their suitability for this particular purpose.

Resumen
Peanuts are one of the leading food crops produced in the United States today. One of the problems of peanut production is disposal of the shells, or hulls, of the peanut, which are generally landfilled. The current research focused on obtaining fibers from the shells, characterizing them, and creating nonwoven fabrics containing these fibers, which were also characterized. The fibers obtained ranged in length from 0.6 cm to 6.3 cm, and were generally stiff. Wet laid nonwovens were produced and a variety of bonding methods such as needlepunching and latex bonding were performed. Latex bonding gave the best results, and the resulting fabrics were characterized in terms of strength, moisture, and light penetration, and thermal insulation capability. The fabrics had similar light and moisture penetration properties as some commercially available erosion control fabrics and thus may be suitable for this purpose. The fabrics also retained some heat, and may be suitable for insulation purpose.

Resumen
Ceramic coated fabrics have been employed for heat resistant clothing such as fire-fighters gears, fire-proof insulators, and heating and cooling insulators. Thus, transient heat conduction and thermal properties of such fabrics are needed for the design of the clothing. The goal of this study is to measure the transient heat conduction and the coefficient of thermal expansion of ceramic coated fabrics with different woven morphologies. This has been accomplished through an experimental setup consists of a hotplate assembly, applying a uniform temperature, with the accuracy of +/− 1 °C in less than 500 msec, a ceramic coated fabric and an infra-red thermometer assembly. This set up has been validated by using a known material such as aluminum and copper for the coefficient of thermal expansion measurement. The hot plate temperature was varied between 30 to 400°C within 300 seconds. The transient heat conduction and the thermal coefficient of the woven ceramic coated fabrics were compared with ceramic nonwoven fabrics materials. Finally, upon comparing different samples and measuring the coefficients of thermal expansion, K’s, the level of delay in heat transfer with respect to time has been determined.
