Woven Apparel Fabrics

This chapter considers the different woven manufacturing processes used in the production of apparel fabrics. It details the mainapparel fabric types and looks at the key performance requirements of those fabrics, in relation to both the weave structure and the fibre type. The chapter then goes on to briefly describe important considerations in the design process and the various end uses for woven fabric. Application examples detailed towards the end of the chapter include fabrics that are timeless classics and fabrics that are established fashion favourites. Key words: apparel, design, applications, performance, fabric aesthetics

ToPoliNano: Nanoarchitectures Design Made Real

Many facts about emerging nanotechnologies are yet to be assessed. There are still major concerns, for instance, about maximum achievable device density, or about which architecture is best fit for a specific application. Growing complexity requires taking into account many aspects of technology, application and architecture at the same time. Researchers face problems that are not new per se, but are now subject to very different constraints, that need to be captured by design tools. Among the emerging nanotechnologies, two-dimensional nanowire based arrays represent promising nanostructures, especially for massively parallel computing architectures. Few attempts have been done, aimed at giving the possibility to explore architectural solutions, deriving information from extensive and reliable nanoarray characterization. Moreover, in the nanotechnology arena there is still not a clear winner, so it is important to be able to target different technologies, not to miss the next big thing. We present a tool, ToPoliNano, that enables such a multi-technological characterization in terms of logic behavior, power and timing performance, area and layout constraints, on the basis of specific technological and topological descriptions. This tool can aid the design process, beside providing a comprehensive simulation framework for DC and timing simulations, and detailed power analysis. Design and simulation results will be shown for nanoarray-based circuits. ToPoliNano is the first real design tool that tackles the top down design of a circuit based on emerging technologie

Wrinkling in engineering fabrics: a comparison between two different comprehensive modelling approaches

We consider two ‘comprehensive’ modelling approaches for engineering fabrics. We distinguish the two approaches using the terms ‘semi-discrete’ and ‘continuum’, reflecting their natures. We demonstrate a fitting procedure, used to identify the constitutive parameters of the continuum model from predictions of the semi-discrete model, the parameters of which are in turn fitted to experimental data. We, then, check the effectiveness of the continuum model by verifying the correspondence between semi-discrete and continuum model predictions using test cases not previously used in the identification process. Predictions of both modelling approaches are compared against full-field experimental kinematic data, obtained using stereoscopic digital image correlation techniques, and also with measured force data. Being a reduced order model and being implemented in an implicit rather than an explicit finite-element code, the continuum model requires significantly less computational power than the semi-discrete model and could therefore be used to more efficiently explore the mechanical response of engineering fabrics

The use of FRPs in seismic repair and retrofit: experimental verification

The application of FRPs in the seismic repair and retrofit of structures is addressed. The results from a few tests on full-scale structures, repaired and/or retrofitted with composites, performed at the ELSA laboratory are presented and discussed

Soil Stabilization Manual 2014 Update

Soil Stabilization is used for a variety of activities including temporary wearing curses, working platforms, improving poor subgrade materials, upgrading marginal materials, dust control, and recycling old roads containing marginal materials. There are a number methods of stabilizing soils including modifying the gradation, the use of asphalt or cement stabilizers, geofiber stabilization and chemical stabilization. Selection of the method depends on the soil type, environment and application. This manual provide tools and guidance in the selection of the proper stabilization method and information on how to apply the method. A major portion of this manual is devoted to the use of stabilizing agents. The methods described here are considered best practices for Alaska.State of Alaska, Alaska Dept. of Transportation and Public Facilitie

Impediments to Growth of the Garment and Food Industries in Cambodia: Exploring Potential Benefits of the ASEAN-PRC FTA

This paper attempts to identify structural constraints to growth and exports within Cambodia’s key industries and to consider the policy actions needed to reduce obstacles to trade. The paper places special emphasis on Cambodia’s exports to the People’s Republic of China (PRC), given the major export opportunities arising from the free trade agreement (FTA) between the Association of Southeast Asian Nations (ASEAN) and the PRC, known as the ASEAN–[People’s Republic of] China FTA (ACFTA). A qualitative case study method was applied at the firm-level by conducting face-to-face interviews to identify the impediments to the growth and exports of key industries in Cambodia, and to examine the opportunities and challenges presented by the ACFTA. This study covers the garment and food industries, which are critical to the economic development of Cambodia in the context of regional and global economic integration. The food industry, with its large number of small and medium-sized enterprises, has great potential for contributing to pro-poor growth in Cambodia, while the textile industry is the largest employer in the Cambodian labor force and is critical for poverty reduction efforts through export-led growth. The study also provides policy recommendations at both the industry and government levels.Cambodian economy; garment industry; food industry; ASEAN-[People’s Republic of] China FTA; firm-level analysis; bribery

Steps towards Sustainability in Fashion: Snapshot Bangladesh A resource for fashion students and educators

This publication offers three case studies, alongside ideas of how they could be used to develop thinking in fashion education. They illustrate some of the different ways sustainability is being approached and interpreted through fashion business in Bangladesh. Case studies of People Tree, New Look and Echotex offer insights into ways in which organisations address long hours, low pay and buying practices. Case study Aranya Crafts offers a view focusing on pioneering work in in natural dyes. The case-studies, published in collaboration with Fashioning an Ethical Industry are an output of a British Council funded Development Partnerships in Higher Education (DelPHE) project bringing together LCF, the BGMEA Institute of Fashion Technology (BIFT) in Dhaka and the United Nations Industrial Development Organization (UNIDO) to deliver research that explores better practice and ways forward to improve the competitiveness of the Bangladesh manufacturing sector to add value in this area
