Full textAbstract:
The quality of the knitted fabric is an important factor in the knitwear industry. On circular knitting machines the fabric quality is improved by using the positive storage feeding device which delivers the length of the yam to the needles in order to form stitches at a constant rate. Yam tension, yam properties and elongation of the yam are important parameters influencing course length in the knitted fabric. However, course length is the most important parameter that determines the dimensions of the knitted fabrics. Therefore, a mathematical analysis was carried out to study the feasibility of using yarn length measurement in order to improve the fabric quality and the process efficiency. A PC based system was created to monitor important information such as yam run-in length, running machine condition, yam breakage, needle breakage, machine and time performance during the normal operation. An addition sensor was installed in order to determine the above parameters. Special hardware and software were developed for monitoring and analysing the knitting process parameters in real-time.

Full textAbstract:
Contemporary knitting over the past decade has experienced a recent resurgence in cultural interest and technical exploration. This research project aims to identify, through personal practice, the implications of knitting as undefined, removed from the boundaries of product. It is the dissolving of the lines between design, art and craft and exploring the domestically machine knitted textile via the use of materials and the inherent qualities of the fabric which are the driving factors of this research. It is through this exploration that my personal and creative process is diversified. The traditional connotations of knitting are historical, social and cultural, in particular hand knitting. Childhood memories of mothers and grandmothers knitting out of necessity, for clothing, often evoke feelings of safety, warmth and comfort. This familiarity of the looped stitches and understanding of the knit as garment binds knitting to fashion. Industrial knitting process, as scale of stitch is reduced, begins to remove this familiarity and creates an anonymity of structure and process, for example jersey knits used for t-shirts. This instant recognition for knitting as clothing is part of the design process where-by knitted fabrics work in unison with product. It is this boundary that has defined my professional practice designing for knitwear. This research involves a more experimental and fluid approach to producing the textile, considering the qualities and potential of the structure as something to celebrate in its own form. Designers such as Issey Miyake, Hussein Chalayan and the artist Rosmarie Trockel have been influential in taking fashion concepts into the gallery, often knitted. This movement of making conceptual and political statements, especially in the case of the industrially knitted pieces by Trockel, was a step to question the traditional and feminist perceptions of knitting and using the process as a material to create art. While these exhibitions explored the knitted textile in the form of fashion garment, the importance of diversifying the knitted cloth and displaying conceptual pieces is a major influence on this research. Also the more recent exhibition 'Radical Lace and Subversive Knitting', (Museum of Arts & Design New York 2007), has allowed for a reinvigorated forum for constructed textiles to be viewed as object, new product or purely as spatial explorations of structure. The impact of these ideas has allowed for the consideration of the textile being stripped back further and to remove the instant connot ation of product application. Exploration of materials, knitted structures and the manipulation of fabric without the constraints of identified product is the impetus of this project. The evolution of the outcomes is instrumental to the reactions of fibres, stitch and interplays of positive and negative space, while suggestions of product are accidental and created by the knitted form as it is removed from the machine. A personal interest in exploiting the knitted structures potential to possess transparency and opacity, become sculptural and changeable by hand have influenced the choices of material and stitch combination. This experimentation has informed my personal practice and the involved process of making.

Full textAbstract:
Human body temperature is an important indicator of physical performance and condition in terms of comfort, heat or cold stress. The aim of this research was to develop Temperature Sensing Fabric (TSF) for continuous temperature measurement in healthcare applications. The study covers the development and manufacture of TSF by embedding fine metallic wire into the structure of textile material using a commercial computerised knitting machine. The operational principle of TSF is based on the inherent propensity of a metal wire to respond to changes in temperature with variation in its electrical resistance. Over 60 TSF samples were developed with combinations of different sensing elements, two inlay densities and highly textured polyester yarn as the base material. TSF samples were created using either bare or insulated wires with a range of diameters from 50 to 150 μm and metal wires of nickel, copper, tungsten, and nickel coated copper. In order to investigate the Temperature-Resistance (T-R) relationship of TSF samples for calibration purposes, a customised test rig was developed and monitoring software was created in the LabVIEW environment, to record the temperature and resistance signals simultaneously. TSF samples were tested in various thermal environments, under laboratory conditions and in practical wear trials, to analyse the relationship between the temperature and resistance of the sensing fabric and to develop base line specifications such as sensitivity, resistance ratio, precision, nominal resistance, and response time; the influence of external parameters such as humidity and strain were also monitored. The regression uncertainty was found to be less than in ±0.1°C; the repeatability uncertainty was found to be less than ±0.5°C; the manufacturing uncertainty in terms of nominal resistance was found to be ± 2% from its mean. The experimental T-R relationship of TSF was validated by modelling in the thermo-electrical domain in both steady and transient states. A maximum error of 0.2°C was found between the experimental and modelled T-R relationships. TSF samples made with bare wire sensing elements showed slight variations in their resistance during strain tests, however, samples made with insulated sensing elements did not demonstrate any detectable strain-dependent-resistance error. The overall thermal response of TSF was found to be affected by basal fabric thickness and mass; the effect of RH was not found to be significant. TSF samples with higher-resistance sensing elements performed better than lower-resistance types. Furthermore, TSF samples made using insulated wire were more straightforward to manufacture because of their increased tensile strength and exhibited better sensing performance than samples made with bare wire. In all the human body wear trials, under steady-state and dynamic conditions both sensors followed the same trends and exhibited similar movement artifacts. When layers of clothing were worn over the sensors, the difference between the response of the TSF and a high-precision reference temperature were reduced by the improved isothermal conditions near the measurement site.

Mermelstein, Sylvia P. "Aspects of the design of a circular warp knitting machine." Thesis, Loughborough University, 2002. https://dspace.lboro.ac.uk/2134/34199.
Full textAbstract:
The warp knitting machine market has long been dominated by large-scale flat models, which have been steadily developed. Tubular fabrics are generally made in a special version of flat warp knitting machines containing two needle bars, one for each side of the tube, joined on the sides by yarns knitting alternatively on each bar. Warp knitting technology has failed to enter the circular knitting industry, dominated by weft knitting, due to its complexity in achieving warp knit structures in circular form. This thesis presents the design, synthesis, manufacture and test of an innovative method of producing tubular warp knitting fabrics, using a circular format rather than flat needle bars. This novel concept opens up many industrial applications from medical textiles to fruit packaging.

Full textAbstract:
Textile process and textile structures that are suitable for composites are carefully studied and chosen to have weft knitted fabrics. The aim of this research is to knit the carbon and Dyneema® fibres in circular weft knitting to fit contour shapes. Carbon/Dyneema® can also be knitted in warp knitting machines to get properties in multi axial direction. But the fabric was flat and can be used only for 2D shape products which are having less drapabiity. According to previous research, weft knitting is the best suitable for complex preforms. Before knitting these fibres properties were studied in order to avoid the damage to the carbon fibres. The carbon fibres have high bending rigidity, low resistance to friction and are very brittle. A small damage to the carbon fibre in knitting subsequently affect directly on the composite properties. The strongest manmade fibre manufactured till date is Dyneema® and these fibres could be used in composites due to its performance, properties and light weight. But, the Dyneema® fibres are expensive when compared to common polyester, so polyester fibres are used to compare the properties and cost performance ratio. The critical bending of the carbon fibres causes friction between the fibres and also between fibre and machine. This was considered carefully during the knitting of carbon fibres and the idea chosen is mentioned in this thesis. Between the two layers of Dyneema®/polyester, carbon fibres are laid circularly in unidirectional and in un-crimped condition. This makes the carbon yarn to possess good mechanical properties. The 2 layers of Dyneema®/polyester fibres exchange the loops at certain points to increase the inter-laminar strength and decrease the carbon fibre distortion. This structure helps to withstand external load. It is also lighter than the carbon composite with additional properties. This makes much more space in the future for the Dyneema® fibres in the 3D carbon composite manufacturing. The internal carbon fibres are fully covered by the Dyneema® fibres to withstand the external impact load and not to damage the carbon fibres. So the loop length, stitch density, fibre volume fractions are considered before knitting.

Full textAbstract:
The possibility of direct preforming in the near net shape of final component structure with load- and shape-conforming fiber orientations is highly essential in composite production, not only to reduce costs but also to attain better mechanical properties and form stability. Based on the concept of varying the reinforcement yarn lengths during the feed-in (warp yarn delivery) and segmented doffing, synchronous working numerically controlled warp yarn delivery and doffing machine modules have been newly developed for multiaxial warp knitting machines to create a resource efficient textile process chain by a single-step, large-scale oriented production of load- and form-conforming warp knitted three-dimensional shell preforms with free-form geometrical surfaces. Such customized preforms in the near component net shape offer higher material utilization and increased lightweight potential.

Previous issue date: 2008-08-15<br>In the manufacture of composite, textile materials are being used as reinforcement. Generally, the combination of the matrix with the textile material in the form of fibres or yarns is used depending on their distribution in the web. In the present work, in place of fibres or yarns, a knitted structure in the form of the final product which is defined as preform. The preform is weft knit manufactured with polyester filaments. In the manufacture of composite, polyester resin was used as matrix. The physical and mechanical properties as well as the formability of the weft knit were analysed. The physical and mechanical properties as well as the
formability of the knitted structure were analysed. The results obtained on the analysis show that the courses and wales of the weft knit structure and the tensile properties help the formability of the structure and the impregnation of the resin. It could be clearly observed that composite structure in the direction of the courses support more tension than in the direction of the wales. In relation to the three points
flexural tests it was possible to note that there was more flexion in the direction of wales, what was expected. It was also possible to note that there are other advantages such as reduction in the loss of materials used, homogeneity in the
distribution of the knitted structure in the mould, reduction in the preparation time and also in the reduction in the cost of manufacture<br>Na fabrica??o de comp?sitos, resultados da jun??o da resina como matriz e o material t?xtil como refor?o, o material t?xtil usualmente utilizado como refor?o, est? no formato de filamentos ou fibras soltas, que s?o aplicados diretamente sobre um molde, essa distribui??o aleat?ria do material pode ocasionar pontos fracos na estrutura j? que n?o garante uma distribui??o homogenia.

Full textAbstract:
Innovative 3D spacer fabrics made from individual planes and connecting layers present great potential as complexly shaped textile preforms in lightweight composite applications. As one of the most flexible textile manufacturing methods, flat knitting enables the production of intricately shaped textile structures. The major advantages coupled with flat knitting techniques include the ability to produce multi-layer reinforcements, a diminishing waste, reducing production time and near-net shaping. This research includes the further development of flat knitting technology and the manufacturing processes of innovative, customized 3D spacer fabrics for high performance composite applications. Novel 3D spacer fabrics have been developed in different geometries using glass-polypropylene commingled hybrid yarns for complex shaped thermoplastic composite components. Reinforcement yarns have been integrated into spacer fabric structures with up to 4 reinforcement layers to improve mechanical performance. Furthermore, the successful addition of “sensor networks” created by integrating functional yarns into the 3D spacer fabrics could be used for structural health monitoring. Innovative integration concepts, which accommodate different positioning of the reinforcement yarns into the knit structures, can be used to adjust the mechanical properties of the finished knit composites. Moreover, the tensile properties have been accurately predicted based on the mathematical models formulated. The developed flat knitted 3D spacer fabrics are very promising for applications in lightweight composites, mechanical engineering, protective textiles, civil engineering and architectural designs<br>Innovative 3D-Spacer Fabrics bestehend aus individuellen Deckflächen und Verbindungsstegen bieten ein großes Potential als komplex geformte textile Halbzeuge für Leichtbauverbundwerkstoffanwendungen.

Belastungsgerechte Verstärkungen, Abfallreduzierung, endkonturnahe Fertigung sind nur einige der großen Vorteile der modernen Flachstricktechnik. Die Forschungsarbeit beinhaltet die Entwicklung der Flachstricktechnologie und des Herstellungsprozesses für innovative 3D-Spacer Fabrics für Hochleistungsverbundwerkstoffe. Neuartige 3D-Spacer Fabrics wurden in unterschiedlichen Geometrien entwickelt, in dem Glas-/ Polypropylen Commingling-Hybridgarn für komplex geformte thermoplastische Verbundwerkstoffkomponenten eingesetzt wird. Verstärkungsfäden wurden für hochmechanische Belastungen in die Spacer-Fabric-Strukturen in bis zu 4 Verstärkungschichten integriert. Die erfolgreiche Umsetzung und Entwicklung von Sensornetzwerken durch die Integration von funktionalen Fäden in die 3D-Spacer Fabrics kann für die strukturelle Zustandsüberwachung genutzt werden. Die innovativen Integrationskonzepte erlauben die differenzierte Orientierung von Verstärkungsfäden in den Gestrickstrukturen, wodurch eine starke Beeinflussung der mechanischen Eigenschaften der Gestrickverbundwerkstoffe herbeigeführt wird. Darüber hinaus wurden die Zugeigenschaften basierend auf den entwickelten mathematischen Modellen vorhergesagt. Die entwickelten flachgestrickten 3D-Spacer Fabrics sind sehr vielversprechend beispielweise für die Anwendung in Leichtbauverbundwerkstoffen, im Maschinenbau, in Schutztextilien, im Bauingenieurwesen und Architekturdesign

Full textAbstract:
Sjöräddningssällskapet har sedan 1907 räddat liv genom frivilliga sjöräddare. De har en vision om att kunna effektivisera sina räddningsaktioner genom att skicka ut en drönare till olycksplatsen för att få en övergripande bild av händelsen och på så sätt kunna anpassa rätt utrustning och personal. Idén var att konstruera drönarens kropp i form av en textil 3D-struktur, detta skulle underlätta dess användning då den skulle bli flexibel och vid olycksplatsen kunna stuvas undan och förflyttas smidigare. Tanken är att drönaren ska ha en konstruktion som kan blåsas upp och bli styv för att sedan kunna tömmas på luft och bli flexibel. Syftet med denna studie är att ta fram en flatstickad distanstextil som ska fungera som en kropp till en drönare där förhoppningen är att den textila 3D-kroppen ska kunna formstickas som en vinge. I distanstextil skapas luftrum mellan lagren vilket möjliggör att en uppblåsbar konstruktion kan skapas. Genom att variera olika parametrar kan man även ta fram önskade egenskaper som styvhet, form, flexibilitet samt lättvikt. För att skapa en distanstextil som är styv i uppblåst läge krävs en beredning. Trikåvaror är generellt svåra att bereda, därför har studien undersökt olika trikåbindningars förmåga att vidhäfta mot beredningar. Den formstickade distansstrukturen i väfttrikå tillverkades på en flatstickmaskin, där formen skapades genom masköverhängningar. Genom att binda distanstråden på olika nålavstånd kunde ett ovalt tvärsnitt uppnås. För att undersöka olika bindningars förmåga att vidhäfta mot beredningar testades flatstickade 2D-prover. Bindningarna var slätstickning, pikévariant över 2 system, pikévariant över 4 system samt slätstickning med plätering. De olika beredningar som undersöktes var silikonbeläggning, polyuretanfilm, polyetenfilm tillsammans med polyuretanfilm samt en polypropenfilm. Syftet var att hitta en beredning som är lätt i vikt, luft- och vattentät. Ett vidhäftningstest utfördes på bindningarna slätstickning, pikévariant över 2 system samt pikévariant över 4 system med hjälp av en dragprovare för bestämning av de olika bindningarnas vidhäftning mot olika lamineringar. De tre bindningarna i kombination med laminering testades även för luft- och vattentäthet. Studien visar att det finns goda möjligheter att formsticka en flatstickad distanstextil som ska fungera som en kropp till en drönare. Resultatet visar att provkroppen som var stickad med pikévariant över två system samt laminerad med polyuretanfilmen gav bäst resultat vid utfört vidhäftningstest. Vid test av luftgenomsläpplighet visade pikévariant över två system med laminering av polyuretanfilm tillsammans med en polyetenfilm tätast resultat med låg luftgenomsläpplighet. Test för bestämning av vattentäthet visar att den slätstickade varan med en laminering med polyetenfilm och en polyuretanfilm gav bäst resultat.<br>Since 1907, the Swedish Sea Rescue Society has saved lives with the help of volunteer workers. Their vision is to be able to improve their rescue operations with quicker respond times by sending out a drone to the scene of an accident. The idea is to get a comprehensive picture of the scene, so they can adapt the right equipment and personnel for the job. The idea is to create a drone with a textile 3D structure, which would ease use as it would become flexible and easier to remove from the scene of the alarm. The drone should have a structure similar to a stand-up paddle board, where it can be inflatable and become stiff and then be deflated and folded and tucked away. The purpose of this study is to develop a flat knitted spacer fabric that will serve as a body of the drone, hoping that the textile 3D structure can be shaped like a wing. With spacer fabrics, space for air is created between the layers, enabling an inflatable construction to be created. By varying different parameters, one can also develop desired features such as stiffness, shape, flexibility and decrease weight. To be able to create a spacer fabric that is stiff when inflated, a finishing process is required. It is generally hard to find a finishing to a knitted fabric, therefore the study investigates the ability of different bindings on a knitted fabric to adhere to finishes. The shaped spacer fabric was manufactured by weft knitting on a flat knitting machine called Stoll CMS 822 HP. A wing shaped spacer and an oval cross section were achieved in this study. To investigate how the binding affects the adhesion of the finishing, three different bindings of flat knitted 2D- structures were tested. The bindings were: plain fabric (single jersey), pique structure over 2 feeders, pique structure over 4 feeders and plain fabric with plating. The finishing processes that were studied were silicone coating, a polyurethane film, a polyethylene film and a polypropylene film. The aim was to find a finishing with the properties of light weight, air and water tightness. An adhesion test was performed on the bindings plain fabric, pique structure over 2 feeders and pique structure over 4 feeders by a tensile tester to determine the adhesion between the tested bindings and finishes. These test specimens were also tested to determine resistance to water penetration and air permeability. The study shows that it is possible to create a shaped spacer fabric by flat knitting, that will act as the body of a drone. The result of the adhesion test shows that the test specimen with binding pique over 2 feeders and laminated with a polyurethane film performed the best. In the air permeability test the same binding showed the best result but with a lamination of a polyurethane film and a polyethylene film. The test to determine resistance to water penetration showed that the binding plain fabric was the best, with a lamination of a polyurethane film, and a polyethylene film.

Full textAbstract:
碩士<br>國立臺灣科技大學<br>材料科學與工程系<br>104<br>When the computerized flat knitting machine for the production of knitting fabric, the property of knitting fabric are determined by the loop length. During the production, the loop length may have some difference because of the abrasion of stitch cam and needle and the variation of yarn. According to this, the study design a loop length compensation system which base on the commercial product and patent. This system use photo-interrupter, roller and microcontroller to measure the loop length and calculate the value of compensation. In the study, we measure the yarn length to test the accuracy and then choose plain stitch and full knit stitch to measure the loop length and calculate the value of compensation. Both of them are knitting in four kinds of stitch value. According to the result, the loop length measuring device can measure the loop length precisely and get the value of compensation in different knitting condition.

碩士<br>逢甲大學<br>紡織工程所<br>93<br>ABSTRACT
With the developing of economy and the improving of the living quality, people have more desires for comfort and functionality in clothing. At the same time, the textile technologies become popularizing and the market have several different needs. At present, the most of traditional fabrics are manufactured by China and Southeast Asia. In this environment, the multifunctional fabrics are created.
In this study, the polyester filaments with Y-cross section, which contains functions of Moisture Absorption and Release, antibacterial and UV-Cut, are warp knitted into fabrics with normal polyester filaments. To reach the goal of maximum economic benefit and functional durability, the optimum manufacture process is discussed in fabric structure and percentage of multi-function filaments. We also can understand how the percentage of multi-function filaments influence the Moisture Absorption and Release, antibacterial, UV-Cut functions and objective handle value assessment by KES system of fabrics.
The experiment results show that when the percentage of multi-function filaments is 16.8%, in despite of the fabric set after dyeing or set after washing or after 20 times of washing, the properties of fabric can reach the requirement of AATCC and AS/NZS4399 standard in antibacterial and UV-Cutting without any auxiliary. The UV-Cut performance also increases with the increasing of the percentage of the multi-function filaments. Because there is no any hydrophilic auxiliary used during the dyeing process, the performance of Moisture Absorption and Release decreases after dyeing. But it recovers a better level after 20 times of water washing and shows the improving in diffusion area test, drying speed test and absorbability test. In the handle value test, the FUKUNAMI value raises with increasing of the percentage of the multi-function filaments, while the KOSHI, SHARI and HARI decrease.
In accordance with all test results, it shows that optimum percentage of multi-function filaments is 16.8% while taking account the manufacturing cost and the performances of fabrics. The product
manufactured with optimum percentage, 16.8%, has more market competitiveness.

Full textAbstract:
碩士<br>逢甲大學<br>纖維與複合材料學系<br>103<br>This study combines 6 D fire-retardant PET fibers and recycled Kevlar selvage by using a nonwoven manufacturing process in order to form Kevlar/PET nonwoven fabrics. The tensile strength, tearing strength, bursting strength, sound absorption coefficient, and limiting oxygen index (LOI) are employed to examine the effect of needle punch number on the nonwoven fabrics. The optimal Kevlar/PET nonwoven fabrics, glass fiber fabric or carbon fiber woven fabrics are a needle punched to form the skin layers of the polyurethane (PU) foam material. During the foaming process exemplified by the reaction between Polyol and Isocyanate (MDI), the rigid PU foam, the skin layer, and the warp knitting spacer fabric are combined in order to form CF/spacer fabric/PU foam composites and GF/spacer fabric/PU foam composites. The effects of foam density and different skin layers on the properties of composites are evaluated by performing a sound absorption coefficient test, a drop-weight impact test, a bursting strength test, a compressive strength test, and a horizontal burning test. The optimal parameters for nonwoven fabrics are needle punch number of 200 needles/min and a basis weight of 200 kg/m2. For GF/spacer fabric/PU foam composites, the horizontal burning test results indicate all samples can reach HF1. The sound absorption coefficient of 0.9 in a frequency range between 2500 and 4000 Hz is satisfactory. The compression strength is proportional to the PU foam density. An optimal residual stress occurs with the PU foam density being 210 kg/m3, while an optimal bursting strength occurs with the PU foam density being 230 kg/m3. Similarly, for the CF/spacer fabric/PU foam composites, they also reach HF1 and have a satisfactory sound absorption coefficient of 0.9 in a frequency range between 2500 and 4000 Hz. Their compressive strength is also proportional to the PU foam density. Their optimal residual stress occurs with a PU foam density being 210 kg/m3 while their optimal bursting strength occurs with a PU foam density being 220 kg/m3. However, the electromagnetic interference shielding effectiveness (EMI SE) of the CF/spacer fabric/PU foam composites is an average of 48 dB that reaches the EMI SE grade required by livelihood necessities.

Full textAbstract:
碩士<br>國立中央大學<br>資訊管理學系在職專班<br>106<br>The textile industry in Taiwan has been progressing in the past 60 years; however, the fabric manufacturer has challenged dyeing factories for delaying the manufacturing process most of the time. This study attempts to identify the challenges that a dyeing factory has on manufacturing scheduling. Advanced Planning & Scheduling System (APS) is a scheduling system that can compute multiple factors to improve manufacturing efficiency. This study will evaluate the feasibility of adopting an APS to overcome the challenges.
The research applies Leavitt’s Diamond Model and conducts a case study to identify the case company’s organizational structure, people’s responsibility, the manufacturing and the operating processes, the system-implementation history, the current scheduling logic that the company applies. The study also evaluates whether or not the current technology infrastructure can support the demand. Furthermore, the study further investigates if the APS is able to resolve the delay problem that the dyeing factory currently has, for helping the company make a solid decision on APS adoption.
The results lead to several major findings. First, the delay problem the company is suffering has been caused by the insufficient capacity, and the remake has further over-loaded the capacity, leading to a vicious circle of delaying. The infrastructure and the database of the company are insufficient for automatically judge the color order depending on the depth, so it is not quite feasible for the company to adopt an APS currently. Instead, the company should build up more data basis, and further analyze the relationship between remake and various manufacturing factors that might interfere the scheduling.
In the future, only when the infrastructure construction of information flow has been setup, can the scheduling be computed by simulation techniques, and the manager can do a relative more solid decision than before.

Abounaim, Md. "Process development for the manufacturing of flat knitted innovative 3D spacer fabrics for high performance composite applications." Doctoral thesis, 2010. https://tud.qucosa.de/id/qucosa%3A25504.
Full textAbstract:
Innovative 3D spacer fabrics made from individual planes and connecting layers present great potential as complexly shaped textile preforms in lightweight composite applications. As one of the most flexible textile manufacturing methods, flat knitting enables the production of intricately shaped textile structures. The major advantages coupled with flat knitting techniques include the ability to produce multi-layer reinforcements, a diminishing waste, reducing production time and near-net shaping. This research includes the further development of flat knitting technology and the manufacturing processes of innovative, customized 3D spacer fabrics for high performance composite applications. Novel 3D spacer fabrics have been developed in different geometries using glass-polypropylene commingled hybrid yarns for complex shaped thermoplastic composite components. Reinforcement yarns have been integrated into spacer fabric structures with up to 4 reinforcement layers to improve mechanical performance. Furthermore, the successful addition of “sensor networks” created by integrating functional yarns into the 3D spacer fabrics could be used for structural health monitoring. Innovative integration concepts, which accommodate different positioning of the reinforcement yarns into the knit structures, can be used to adjust the mechanical properties of the finished knit composites. Moreover, the tensile properties have been accurately predicted based on the mathematical models formulated. The developed flat knitted 3D spacer fabrics are very promising for applications in lightweight composites, mechanical engineering, protective textiles, civil engineering and architectural designs.<br>Innovative 3D-Spacer Fabrics bestehend aus individuellen Deckflächen und Verbindungsstegen bieten ein großes Potential als komplex geformte textile Halbzeuge für Leichtbauverbundwerkstoffanwendungen. Mit Hilfe des Flachstrickens, welches einer der flexibelsten textilen Herstellungsprozesse ist, lassen sich komplex geformte textile Strukturen herstellen. Belastungsgerechte Verstärkungen, Abfallreduzierung, endkonturnahe Fertigung sind nur einige der großen Vorteile der modernen Flachstricktechnik. Die Forschungsarbeit beinhaltet die Entwicklung der Flachstricktechnologie und des Herstellungsprozesses für innovative 3D-Spacer Fabrics für Hochleistungsverbundwerkstoffe. Neuartige 3D-Spacer Fabrics wurden in unterschiedlichen Geometrien entwickelt, in dem Glas-/ Polypropylen Commingling-Hybridgarn für komplex geformte thermoplastische Verbundwerkstoffkomponenten eingesetzt wird. Verstärkungsfäden wurden für hochmechanische Belastungen in die Spacer-Fabric-Strukturen in bis zu 4 Verstärkungschichten integriert. Die erfolgreiche Umsetzung und Entwicklung von Sensornetzwerken durch die Integration von funktionalen Fäden in die 3D-Spacer Fabrics kann für die strukturelle Zustandsüberwachung genutzt werden. Die innovativen Integrationskonzepte erlauben die differenzierte Orientierung von Verstärkungsfäden in den Gestrickstrukturen, wodurch eine starke Beeinflussung der mechanischen Eigenschaften der Gestrickverbundwerkstoffe herbeigeführt wird. Darüber hinaus wurden die Zugeigenschaften basierend auf den entwickelten mathematischen Modellen vorhergesagt. Die entwickelten flachgestrickten 3D-Spacer Fabrics sind sehr vielversprechend beispielweise für die Anwendung in Leichtbauverbundwerkstoffen, im Maschinenbau, in Schutztextilien, im Bauingenieurwesen und Architekturdesign.
