The book presents the latest developments in narrow fabrics and smart materials from research institutions, machinery building companies and producers of such products, presented during the International Week of Narrow and Smart Textiles in Spring 2018 in Moenchengladbach, Germany. It also demonstrates different applications of braided and woven fabrics. Braided and woven narrow products are produced using completely different techniques, but have a lot of similarities in their applications - they are used as belts, ropes and tubes in areas ranging from medical textiles, cables, technical and home applications to large-scale transport belts and long tubes for transporting oil from the bottom of the ocean.
Inorganic and Composite Fibers: Production, Properties, and Applications provides a comprehensive review on the development, production and application of modern inorganic and composite fibers. Particular emphasis is placed on current production processes, parameters and finishing and functionalization methods for improving their properties and the problems associated with the testing of fibers. Fibers covered include carbon, glass and basalt fibers, metal fibers, such as copper and steel, fibers coated with silver or gold, and nitinol. In addition to pure inorganic fibers, the book looks at organic fibers with a high level of inorganic content, such as cellulosic fibers. Including contributions from leading experts from universities, research institutes, and producing companies, this book assists materials scientists and engineers in the composites, automotive, textile and medical industries to more efficiently and effectively select fibers for a range of different applications areas.
Textile materials or materials made from textiles are probably among the most important materials in the world. Textile materials are not only present everywhere in modern daily life, but have been for thousands of years. Besides obvious textile applications such as clothes or hometextile there are also many more hidden applications. For example, textile filters, textiles in production processes or composite materials are just a few ways that they can be applied. Altogether, it is implied that modern civilization without textiles is not possible. This book is dedicated to the advances in textile research and application. Here, readers must keep in mind that the final textile in the final application is the product of many different production steps, which is known as the textile chain. Many different disciplines contribute to this textile chain, such as chemistry and machine engineering but also less obvious influences like agricultural science in terms of cotton or wool fiber production. The life of a textile material starts with fiber production; this can be a natural process for plant fibers, animal fibers or regenerated fibers from natural resources. In contrast, chemical fibers see their origin via chemical synthesis. After fiber production, yarn production follows, which is in the field of spinning technology. From the yarn comes the textile materials as fabrics or non-wovens are produced using processes such as weaving, knitting, braiding, etc. These textile products are further modified by dyeing and printing processes. Finishing is often also used to realize special functional properties on a textile product. Finally, the textile product is realized as either cloth, home textile or technical application. Besides technical aspects, design and marketing also play an important role. After following this summary, it is obvious that this book cannot cover every single aspect of textile and textile products. Therefore, this book headlines with every chapter a topic in the area of textile research and application, which is a topic in actual scientific research but also in industrial development. The main topics include: microwave based processes, plasma technology, photoactive textiles, electrospinning, braiding processes, wool materials, coatings, textile functionalization, and UV-protective and light responsive materials This book is dedicated to readers from universities and industries that engage in some form of textile production. For the industry, it can help to promote ideas for new innovative processes and products. For university students especially graduates s it can help to broaden their expertise in very different fields of the textile world. Also, established scientists could benefit from this text to use as a tool to generate new ideas for further research.
Diplomarbeit aus dem Jahr 1998 im Fachbereich Chemie - Physikalische und Theoretische Chemie, Note: 1,0, Universitat Bremen (Unbekannt), Sprache: Deutsch, Abstract: Inhaltsangabe: Einleitung: Die Plasmapolymerisation ist ein Verfahren zur Produktion von dunnen Polymerschichten bis zu 105 nm Dicke. Bei dem Plasmapolymerisationsprozess wird durch das Einwirken eines Plasmas auf gasformige, organische Molekule eine Polymerbeschichtung erzeugt. Die so gebildeten Polymerschichten weisen eine komplexe und hochvernetzte Struktur auf. In den letzten 20 Jahren hat die Plasmapolymerisation einen grossen Aufschwung erfahren und sich zu einem Verfahren mit grosser technischer Bedeutung entwickelt. Eingesetzt wird die Plasmapolymerisation zur Produktion von wasserundurchlassigen sowie wasserabweisenden Materialien. Weitere Einsatzgebiete finden sich im Korrosionsschutz, in der Herstellung von abriebsmindernden Schichten, Diffusionsbarrieren und elektrisch leitfahigen Schichten. Im Gegensatz zur Plasmapolymerisation werden Metallcluster schon seit Jahrhunderten genutzt. Die ersten Anwendungen finden sich bereits im Altertum in der Herstellung farbiger Glaser durch Einfarben mit Metallpartikeln. Auf ein grosses wissenschaftliches Interesse stiessen die Metallcluster bereits zu Anfang dieses Jahrhunderts. So beschrieb Wo. Ostwald besonders eindrucksvoll 1915 in dem Buch Die Welt der vernachlassigten Dimensionen" Cluster und ihre Eigenschaften. Als Cluster werden in der Chemie und Festkorperphysik kleine Teilchen von Metallen und Halbmetallen bezeichnet. Es werden dabei kleine Cluster mit einem Durchmesser bis zu 4 nm von grossen Clustern mit einer Grosse von 4 bis 100 nm unterschieden. Die Atomanzahl reicht bei kleinen Clustern von weniger als 10 bis zu 500 Atomen. Die grossen Cluster, welche auch Kolloide genannt werden, konnen bis zu 10 Atome beinhalten. Die Praparation von Clustern aus verschiedensten Metallen in Plasmapolymermatrizen wird in der Literatur ausfuhrlich beschriebe
