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.

Resumen

ABSTRACT Introduction Developing affordable and effective hemostatic and antimicrobial wound dressings for prolonged field care (PFC) of open wounds is of interest to prevent infection, to prevent sepsis, and to conserve tissue viability. The need for an effective hemostatic dressing that is also antimicrobial is required of a hemostatic dressing that can be left in place for extended periods (days). This is particularly important in light of the existence of pathogens that have coagulopathy properties. Thus, dressings that provide effective hemostasis and reduction in the frequency of dressing changes, whereas exerting robust antimicrobial activity are of interest for PFC. Highly cleaned and sterile unbleached cotton has constituents not found in bleached cotton that are beneficial to the hemostatic and inflammatory stages of wound healing. Here, we demonstrate two approaches to cotton-based antimicrobial dressings that utilize the unique components of the cotton fiber with simple modification to confer a high degree of hemostatic and antimicrobial efficacy. Methods Spun bond nonwoven unbleached cotton was treated using traditional pad dry cure methods to add ascorbic acid, zeolite (NaY) with pectin, calcium chloride, and sodium carbonate/calcium chloride. Similarly, nanosilver-embedded cotton fiber was blended with pristine cotton fibers at various weight ratios to produce hydroentangled nonwoven fabrics. The resulting treated fabrics were assessed for hemostasis using thromboelastographic clotting assays and antimicrobial activity utilizing American Association of Textile Chemists and Colorists 100. Results Zeolite-containing dressings possessed significant hemostatic activity, whereas ascorbic acid- and silver-containing dressings reduced Gram-positive and Gram-negative organism numbers by several logs. Conclusion Based on this study, a multilayered hemostatic dressing with antimicrobial properties is envisioned. This dressing would be safe, would be economical, and have a stable shelf-life that would be conducive for using PFC.

Resumen

An analytical mathematical model for friction between a fabric strip and the volar forearm has been developed and validated experimentally. The model generalizes the common assumption of a cylindrical arm to any convex prism, and makes predictions for pressure and tension based on Amontons' law. This includes a relationship between the coefficient of static friction ( μ) and forces on either end of a fabric strip in contact with part of the surface of the arm and perpendicular to its axis. Coefficients of friction were determined from experiments between arm phantoms of circular and elliptical cross-section (made from Plaster of Paris covered in Neoprene) and a nonwoven fabric. As predicted by the model, all values of μ calculated from experimental results agreed within ±8 per cent, and showed very little systematic variation with the deadweight, geometry, or arc of contact used. With an appropriate choice of coordinates the relationship predicted by this model for forces on either end of a fabric strip reduces to the prediction from the common model for circular arms. This helps to explain the surprisingly accurate values of μ obtained by applying the cylindrical model to experimental data on real arms.

Resumen

In this review, we report the functionalization of textiles composed of nanoscale reactive materials in the treatment of wounds and skin diseases such as acne. In view of the growing demand for high-quality textiles, much research is focused on the creation of antimicrobial finishings for fabrics, in order to protect customers from pathogenic or odorgenerating microorganisms. We present coatings from inorganic, organic and biochemical nanoparticles (NPs) on surfaces that impart the ability to kill bacteria, avoid biofilm formation and speed up the recovery of wounds. In all three cases, sonochemistry is used for immobilizing the nanoparticles on the surfaces. The Introduction broadly covers the progress of nanotechnology in the fields of wound and skin care. The first section of this review outlines the mechanism of the ultrasound-assisted deposition of nanoparticles on textiles. The coating can be performed by an in-situ process in which the nanoparticles are formed and subsequently thrown onto the surface of the fabrics at a very high speed. This approach was used in depositing metal-oxide NPs such as ZnO, CuO and Zn-CuO or the organic NPs of tannic acid, chitosan, etc. on textiles. In addition, the sonochemical process can be used as a "throwing stone" technique, namely, previously synthesized or commercially purchased NPs can be placed in the sonication bath and sonicated in the presence of the fabric. The collapse of the acoustic bubble in the solution causes the throwing of the immersed commercial NPs onto the textiles. This section will also outline why sonochemical deposition on textiles is considered the best coating technique. The second section will discuss new applications of the sonochemically- coated textiles in killing bacteria, avoiding biofilm formation and more. Two points should be noted: 1) the review will primarily report results obtained at Bar-Ilan University and 2) since for all textiles tested in our experiments (cotton, polyester, nylon, nonwoven) similar results were obtained, the type of textile used in a specific experiment will not be mentioned - textiles will be discussed in general. It is also worth emphasizing that this review concentrates only on the sonochemical coating of textiles, ignoring other deposition techniques.

Resumen

In this study, different conventional personal protection devices (fibrous filters, cartridges for respirators, protective clothing, and gloves) well qualified for micron particles were tested with graphite nanoparticles ranging from 10 to 100 nm (electrical mobility diameter). For this purpose, two specific test benches were designed: one for filter-based devices which are tested under a controlled air flow and other for gloves and protective clothing based on the “through diffusion method.” The penetration versus particle size shows for most tested filter media the behavior predicted by the theoretical Brownian capture: penetration decreases when particle diameter decreases. No thermal rebound was detected until 10 nm for graphite nanoparticles. Protective clothes were tested by two methods and same trends were obtained. Nonwoven fabrics (air-tight materials) are much more efficient against nanoparticles than cotton and paper. Gloves tested by “through diffusion technique,” in static condition seem to efficiently protect against graphite nanoparticles in spite of their important porosity.

Resumen

The aim of this study was to evaluate a novel composite material for tracheal reconstruction in an ovine model. A polymer containing various forms of carbon fibers (roving, woven, and nonwoven fabric) impregnated with polysulfone (PSU) was used to create cylindrical tracheal implants, 3 cm in length and 2.5 cm in diameter. Each implant, reinforced with five rings made of PSU-impregnated carbon-fiber roving, had three external layers made of carbon-fiber woven fabric and the inner layer formed of carbon-fiber nonwoven fabric. The inner surface of five implants was additionally coated with polyurethane (PU), to promote migration of respiratory epithelium. The implants were used to repair tracheal defects (involving four tracheal rings) in 10 sheep (9-12 months of age; 40-50 kg body weight). Macroscopic and microscopic characteristics of the implants and tracheal anastomoses were examined 4 and 24 weeks after implantation. At the end of the follow-up period, outer surfaces of the implants were covered with the tissue which to various degree resembled histological structure of normal tracheal wall. In turn, inner surfaces of the prostheses were covered only with vascularized connective tissue. Inner polyurethane coating did not improve the outcomes of tracheal reconstruction and promoted excessive granulation, which contributed to moderate to severe stenosis at the tracheal anastomoses. The hereby presented preliminary findings constitute a valuable source of data for future research on a tracheal implant being optimally adjusted for medical needs.

Resumen

Chemically recycled polyester fibers consisting of a core and sheath layer were used to produce nonwoven fabrics for ecofriendly automotive interiors. The density and thermal shrinkage of the recycled polyester nonwoven fabrics were higher than in virgin polyester nonwoven fabrics, irrespective of the heat-setting temperature and time, but the air permeability was lower. The wicking property of the recycled polyester nonwoven fabrics decreased significantly above 180℃. The tensile stress and modulus of the recycled polyester nonwoven fabrics increased gradually with increasing heat-setting temperature. However, the strain at maximum stress of the recycled polyester nonwoven fabrics decreased rapidly. The abrasion strength of the recycled polyester nonwoven fabrics improved above a heat-setting temperature of 200℃. The impact strength of the recycled polyester nonwoven fabrics was higher than that of virgin polyester nonwoven fabrics. As the heat-setting temperatures used for the nonwoven fabrics were higher than the melting temperature of chemically recycled and virgin polyester fibers, thermal bonding occurred between fibers. The lightness of the recycled polyester nonwoven fabrics decreased with increased heat-setting temperature and time. The recycled polyester nonwoven fabrics also showed slight yellowing. The thermal bonding between the fibers in the recycled polyester nonwoven fabrics was generated at a lower heat-setting temperature than for virgin polyester nonwoven fabrics, and therefore it is considered that under more relaxed heat treatment conditions, the recycled polyester nonwoven fabrics would show a performance similar to that of the virgin ones.

Resumen

Electromagnetic wave shielding effectiveness of the nonwoven fabrics was measured in the wide operating frequency range, namely 0.4GHz to 20GHz. The shielding effectiveness of the nonwoven fabric was below 45dB in the range of 0.04GHz to 15GHz and then it increased to above 45dB in the range of 15GHz to 20GHz. To enhance the electromagnetic wave shielding effectiveness of the nonwoven fabrics, 3 minutes H2 plasma treatment of the nonwoven fabrics was carried out under the microwave plasma-enhanced chemical vapor deposition system. By H2 plasma treatment, the shielding effectiveness of the nonwoven fabrics was greatly enhanced in the whole operating frequency range. The surface electron conductivity of the nonwoven fabrics was also enhanced from 2.11×103 S/m to 3.02×103S/m by H2 plasma treatment. The surface and cross sectional morphologies of the nonwoven fabrics with or without H2 plasma treatment were investigated and compared with each other. Crystal structure variation of the nonwoven fabrics by H2 plasma treatment was also investigated. Based on these results, the cause for the enhancement of the shielding effectiveness of the nonwoven fabrics by H2 plasma treatment was suggested and discussed.

Resumen

This study aims to examine the thickness of a sandwich structure and the lamination number of the Kevlar nonwoven fabrics o n the punch resistance strength and impact resistance strength of the nonwoven composites. Kevlar nonwoven fabrics and Nylon/low-melting-point polyethylene terephthalate (LPET) nonwoven fabrics are laminated with various combinations to form sandwich-structured nonwoven composites. The experiment results show that an increasing number of Kevlar nonwoven fabrics results in low dynamic and constant rate puncture resistance but high impact strength; and conversely, an increasing thickness of sandwich-structured nonwoven composites causes high dynamic and constant rate puncture resistances but low impact strength.

Resumen

In this research, the nonwoven fabrics were made of 50 % high-tenacity polyester fiber and 50 % low melting polyester fiber, after which the nonwoven fabrics were thermal-treated at 110 °C, 120 °C, 130 °C, 140 °C and 150 °C for 1 min, 2 min, 3 min, 4 min and 5 min. Next, two layers of nonwoven fabrics were laminated with a layer glass (GF) fiber plain fabric or a layer of Nylon 66 grid, forming the sandwich structure. The nonwoven/ GF composite fabrics and the nonwoven/ Nylon 66 grid composite fabrics were also reinforced by needle-punching and thermal treatment, after which the two composite fabrics were measured with tensile strength and stab-resistant strength. Meanwhile, two layers of nonwoven fabrics needle-punched served as the control group. According to the results, Nylon 66 grid and glass fibers plain fabrics were both good at strengthening, the former reinforced the tensile strength of the composite fabrics and the later heightened the stab-resistant strength of the composite fabrics.

Resumen

Conductive textiles can be used in diverse fields, such as antistatic materials, sensors, materials for electromagnetic shielding and biomedical. This study produces nonwoven fabrics with polylactic acid (PLA) and polyaniline (PAN) and the resulting PLA/PAN nonwoven fabrics are evaluated with electromagnetic shielding effectiveness (EMSE) and air permeability. Polylactic acid (PLA) and low melting point polylactic acid (LPLA) are made into nonwoven fabrics, which are then spray-coated with different amount of PAN solution to form PLA/PAN nonwoven fabrics. The fabrics are laminated with various numbers of layers, and then thermally pressed. The experiment results show that the PAN amount and lamination number are proportional to the EMSE of the PLA/PAN nonwoven fabrics.

Resumen

Currently, nonwoven fabrics made with natural and thermoplastic commingled fibers have been extensively used in the composite industry due to their light weight and low processing and material costs. As two key parameters in the manufacturing of nonwoven fabrics, the needle-punching and material surface densities influence strongly the mechanical properties of nonwoven fabrics and their reinforced composite parts. Compared to most studies focused on the composite stage, the present experimental investigation is performed at the dry fabric stage, and the influence of the needle-punching and material surface densities on the mechanical behavior of nonwoven fabrics will be analyzed through tensile and bending tests. The results show that increasing the material surface of the nonwoven fabric leads to a better mechanical behavior, but that such variations do not modify the phenomenon of anisotropy of nonwoven fabrics. By contrast, increasing the needle-punching density can strengthen generally the homogeneity of nonwoven fabrics.

Resumen

This research is to develop a processing technique for fabricating the three-dimensional nonwoven fabric with the sound absorption capability and flame retardant capability. Furthermore, the physical properties and functionalities of the three-dimensional nonwoven fabric are adequately evaluated and tested. Several nonwoven fabrics are fabricated by two polyester fibers with different denier numbers and the low-melting-point fibers. Then, multiple nonwoven fabrics are used to make three-dimensional nonwoven fabrics through lapping, needle-punching process. After being reinforced by heating in the hot air circulation oven, the physical properties of three-dimensional nonwoven fabrics such as tensile strength, breathability, sound-absorption coefficients, limiting oxygen index (LOI), and thermal conductive coefficients are properly evaluated. Subsequently, the influence of fiber faintness on the performance of sound-absorption and thermal insulation of three-dimensional nonwoven fabrics is carefully examined through the obtained results.

Resumen

Nonwoven fabric technique has been extensively used because nonwoven fabrics can uses both filaments and staple fibers and have ease of processing, a wide range of raw material sources, and a short production. This study makes protective nonwoven fabrics with Kevlar fibers, flame retardant polyester (FPET) fibers, and low-melting-point polyester (LPET) fibers. The number of lamination layers of the nonwoven fabric is varied and examined to determine their influence on the mechanical properties of the protective nonwoven fabrics. The results of test show that tensile strength and bursting strength of the protective nonwoven fabrics increase as a result of the increased number of lamination layer.
