Modelling And Predicting Textile Behaviour

The textile industry can experience a vast array of problems. Modelling represents a group of techniques that have been widely used to explore the nature of these problems, it can highlight the mechanisms involved and lead to predictions of the textile behaviour. This book provides an overview of how textile modelling techniques can be used successfully within the textile industry for solving various problems. The first group of chapters reviews the different types of models and methods available for predicting textile structures and behaviour. Chapters include modelling of yarn, woven and nonwoven materials. The second group of chapters presents a selection of case studies, expressing the strengths and limitations and how various models are applied in specific applications. Case studies such as modelling colour properties for textiles and modelling, simulation and control of textile dyeing are discussed. With its distinguished editor and international range of contributors, Modelling and predicting textile behaviour is essential reading material for textile technologists, fibre scientists and textile engineers. It will also be beneficial for academics researching this important area. Provides an overview of the different types of models and methods that can be used successfully within the textile industry Reviews the structural hierarchy in textile materials fundamental to the modelling of textile fibrous structures Assesses the strengths and weaknesses of different textile models and how specific models are applied in different situations

Welcome to the 3rd Indonesian Textile Conference (ITC) 2019. It is our great honor and pleasure to have you all here today. Indonesian Textile Conference is by far the only scientific event in the field of textiles in Indonesia aimed to bring together leading researchers, experts, students and people from the industry to share their knowledge and exchange scientific ideas. Indonesia is one of the leading textile exporter countries in the world with a total export value of USD 15.3 billion in 2015 and ranked the third after palm oil and steel (source: Ministry of Industry of Republic of Indonesia). It is one of the ten priority industries and the mainstay of Indonesian national industry. In a global economy and fast changing world, the future of Indonesian textile industry will increasingly depend on the industry’s ability to relentlessly innovate in its products, to use the most advanced, flexible and resource-efficient processes and to focus its organizational structure as well as business operations according to the ever changing and growing needs of its customers. In all that, research and innovation are vital and play an ever increasing role. Indonesian Textile Conference was initiated and is dedicated to promote and bring progress to research and innovation in the field of textile and textile-related subjects in Indonesia. Textile is a rich multidisciplinary area of study and in fact has attracted a great deal of attention and numerous contributions from non-textile scientists. It is not just about clothing. It is all about material and all aspects that are inherent in the process of its production and applications. It covers a whole lot of area which includes but not limited to: advanced material and textile fibers, natural fibers and natural dyes, utilization of natural sources for textiles in general and/or functional textiles, environmental protection and ecological considerations in textile industry, life cycle analysis, clean/green production, best practices in energy efficient processes, bio-based polymer, bioengineering, nanotechnology, textile-based composites, industrial management and engineering, traditional textiles and batik, textile preservation and conservation, and design. Smart, functional and interactive textile is another area of interest which is quite recent and resulted from the convergence of latest developments in material science, physics and chemistry, microelectronics and informatics. Stimuli responsive materials, self-healing polymers, textile energy devices, textile sensor and antenna are only a few examples of development in this area. Recently added to this is a new emerging “fashionable technology”. It is a new concept that brings fashion to the next level by integrating technology and fashion. It looks at the future fashion as intersection of design, fashion, science, and technology beyond wearable technology. Still another important and interesting issue in textile is sustainability, especially due to the stigma associated with the industry as the big polluter and being not environmentally-friendly. Sustainable textiles and clothing involves the choice of materials, technologies and processing methods that ensure environmental and social friendliness and safety to human health throughout the entire life-cycle phases. Thus, there is an ample room for almost everyone to contribute in this conference. On behalf of the Organizing Committee and the management of Politeknik STTT Bandung, have a productive and fruitful conference.

Multi-scale modelling of composites is a very relevant topic in composites science. This is illustrated by the numerous sessions in the recent European and International Conferences on Composite Materials, but also by the fast developments in multi-scale modelling software tools, developed by large industrial players such as Siemens (Virtual Material Characterization toolkit and MultiMechanics virtual testing software), MSC/e-Xstream (Digimat software), Simulia (micromechanics plug-in in Abaqus), HyperSizer (Multi-scale design of composites), Altair (Altair Multiscale Designer) This book is intended to be an ideal reference on the latest advances in multi-scale modelling of fibre-reinforced polymer composites, that is accessible for both (young) researchers and end users of modelling software. We target three main groups: This book aims at a complete introduction and overview of the state-of-the-art in multi-scale modelling of composites in three axes: • ranging from prediction of homogenized elastic properties to nonlinear material behaviour • ranging from geometrical models for random packing of unidirectional fibres over meso-scale geometries for textile composites to orientation tensors for short fibre composites • ranging from damage modelling of unidirectionally reinforced composites over textile composites to short fibre-reinforced composites The book covers the three most important scales in multi-scale modelling of composites: (i) micro-scale, (ii) meso-scale and (iii) macro-scale. The nano-scale and related atomistic and molecular modelling approaches are deliberately excluded, since the book wants to focus on continuum mechanics and there are already a lot of dedicated books about polymer nanocomposites. A strong focus is put on physics-based damage modelling, in the sense that the chapters devote attention to modelling the different damage mechanisms (matrix cracking, fibre/matrix debonding, delamination, fibre fracture,...) in such a way that the underlying physics of the initiation and growth of these damage modes is respected. The book also gives room to not only discuss the finite element based approaches for multi-scale modelling, but also much faster methods that are popular in industrial software, such as Mean Field Homogenization methods (based on Mori-Tanaka and Eshelby solutions) and variational methods (shear lag theory and more advanced theories). Since the book targets a wide audience, the focus is put on the most common numerical approaches that are used in multi-scale modelling. Very specialized numerical methods like peridynamics modelling, Material Point Method, eXtended Finite Element Method (XFEM), isogeometric analysis, SPH (Smoothed Particle Hydrodynamics),... are excluded. Outline of the book The book is divided in three large parts, well balanced with each a similar number of chapters:

The use of mathematical modelling and computer simulation can vastly improve the quality, efficiency and economic success of textile technology. Simulation in textile technology provides a comprehensive review of the key principles, applications and benefits of modelling for textile production. After an introduction to modelling and simulation, Simulation in textile technology goes on to review the principles and applications of the main types of model.

It then considers computational fluid dynamics and finite element modelling. The modelling of fibrous structures and yarns are considered in the following chapters, along with wound packages, woven, braided and knitted structures.
