La demande de fibre para-aramide haute performance Twaron de Teijin est en pleine croissance, et cette nouvelle technologie de filature permettra à l'organisation d'augmenter sa capacité de production et de répondre à la demande du marché. Teijin Aramid investit continuellement dans sa technologie afin de créer des produits et des solutions d'aramide innovants en collaboration avec ses clients. Ces dernières années, l'entreprise a investi cinq pour cent de son chiffre d'affaires annuel dans les activités de recherche et développement. Twaron, la super-fibre de Teijin Aramid, est de plus en plus utilisée dans des produits de plus en plus avancés dans différents secteurs. Gert Frederiks, PDG de Teijin Aramid, a déclaré : « Cet investissement souligne notre ambition de produire et d'offrir des produits durables et économiques sur le marché et vient renforcer notre position de leader sur le marché mondial. Il nous permettra de répondre à la demande croissante du marché tout en mettant en œuvre notre dernière technologie. » L'expansion de la capacité de filature devrait débuter au premier trimestre de l'année 2019. La nouvelle technologie permettra également une plus grande automatisation du processus de filature, ce qui constitue une énorme amélioration pour la charge de travail physique des opérateurs. Cette évolution est conforme aux plans de Teijin Aramid qui souhaite automatiser davantage la production et améliorer les aspects HSE (hygiène, sécurité et environnement) de l'entreprise. Au 1er avril 2017, Teijin a fusionné toutes ses activités d'aramide en une seule entité opérationnelle. Depuis lors, Teijin Aramid est responsable de tous les produits d'aramide et de polyéthylène que l'entreprise produit, développe et vend. Ainsi, l'organisation Teijin Aramid dispose désormais de sites de production d'aramide en Thaïlande (Teijinconex neo), au Japon (Teijinconex et Technora) et aux Pays-Bas (Twaron et Endumax). À propos de Teijin Aramid Teijin Aramid est une filiale de Teijin Group et le leader mondial des aramides. Pour plus d'informations : http://www.teijinaramid.com et http://www.teijinendumax.com.

The chemistry and physics of high-performance fibre spinning based on main-chain liquid crystal polymer (MCLCP) solutions and melts is discussed, which is the largest industrial application of liquid crystal technology. The high modulus and strength of liquid crystal polymer-based high-performance fibres is due to the exceptionally high orientational order that can be achieved, reaching values of 0.95 and higher. Together with the chemistry that ensures strong intermolecular interactions, often based on hydrogen bonding, it is possible to make fibres with unusual mechanical and thermal properties. The modulus and strength of such fibres can reach values at about 50-75% of the theoretical limit.Within materials science high-performance fibres are especially interesting, as they are one of the few systems where the material properties can be successfully predicted based on molecular models for the orientational order together with rather simple assumptions on the effect of flow on the director alignment. The most studied MCLCP systems for high-performance fibre spinning PPTA/H 2SO 4, cellulose/phosphoric acid, PIPD(M5)/PPA and melt-spun Vectran™ are discussed. © 2011 Taylor & Francis.

Businesses have a responsibility to shareholders and other stakeholders. By establishing a direct link between sustainability and shareholder value, businesses can successfully include sustainability considerations in managerial decisions and create sustainable value. The value creation opportunities include cost reduction, risk reduction, product differentiation, and new products to address unsatisfied needs. However, the relevance of various aspects of sustainability changes from company to company depending on the context; this can involve the type of product systems, geographical scope, and related social and environmental drivers. This requires a framework and tool that can capture the complexity, yet provide holistic understanding of the interdependence of industrial systems and, more importantly, furnish sound metrics to include sustainability considerations in business decisions. This paper shows how value can be created by integrating environmental sustainability through Life Cycle Assessment in business, especially in the chemical industry and provides an implementation procedure for business value creation based on life cycle assessment. The application of life cycle assessment was contextualized to various drivers and situations of chemical companies with the help of sustainable value framework. Case studies from three companies were used to illustrate value creation by integrating environmental sustainability through life cycle assessment. A procedure was presented to translate life cycle assessment insights into value creation opportunities. This article provides a better understanding of employing life cycle assessment by business managers in day-to-day business decisions to create value. © 2016 Elsevier Ltd.

Our objective is to predict the time-to-failure distribution of fibers at loads for which mean time-to-failure is comparable or longer than the fibers’ economic lifetime. We describe load induced time-to-failure of high performance fiber in terms of a classical probabilistic failure model developed by Coleman. Mimicking a series of time-to-failure measurements, using Monte Carlo simulations, we will show how to capture model parameters and their variability using the least squares method and maximum likelihood estimation. It is relatively easy to obtain an accurate prediction for the maximum allowable fiber load such that time-to-failure exceeds a predefined minimum time-to-failure with high probability. However, obtaining a reliable lower prediction limit for time-to-failure at a given, low fiber load is very difficult and requires an unfeasible extensive program of time-to-failure measurements. © 2015, Springer Science+Business Media New York.

An elementary, probabilistic model for fiber failure, developed by Coleman in the fifties of the last century, predicts a Weibull distributed time-to-failure for fibers subject to a constant load. This has been experimentally confirmed, not only for fibers but for load-bearing products in general. In this paper, we analyze residual strength, i.e., the strength after having survived a given load program. We demonstrate that the Weibull modulus, describing variability of time-to-failure, affects residual strength. It determines (a) how fast residual strength of fibers decays during their service life, (b) the residual strength variability, and (c) the fraction of surviving fibers during service life. Experiments show that residual strength of Twaron fiber (p-aramid fiber), exceeding predictions of Coleman’s model, remains unrelentingly high (close to virgin strength) during service life. © 2016 Springer Science+Business Media New York

Measurements of the electrical resistivity, from 1.5 to 300 K, and of the low temperature magnetoresistance of highly conductive carbon nanotube (CNT) fibers, obtained by wet-spinning from liquid crystalline phase (LCP), are reported. At high temperature the results obtained on the raw CNT fibers show a typical metallic behavior and the resistivity levels without postdoping process were found to be only one order of magnitude higher than the best electrical conductors, with the specific conductivity (conductivity per unit weight) comparable to that of pure copper. At low temperature a logarithmic dependence of the resistivity and the temperature dependence of the negative magnetoresistance are consistent with a two-dimensional quantum charge transport - weak localization and Coulomb interaction - in the few-walled CNT fibers. The temperature dependence of the phase-breaking scattering rate has also been determined from magnetoresistance measurements. In the temperature range T<100K, electron-electron scattering is found to be the dominant source of dephasing in these highly conductive CNT fibers. While quantum effects demonstrate the two-dimensional aspect of conduction in the fibers, the fact that it was found that their resistance is mainly determined by the intrinsic resistivity of the CNTs - and not by intertube resistances - suggests that better practical conductors could be obtained by improving the quality of the CNTs and the fiber morphology. © 2015 American Physical Society.
