Book Description
Wear comfort has been listed as the most important property of clothing demanded by users and consumers according to recent studies. A fundamental understanding of human comfort and a knowledge of how to design textiles and garments to maximise comfort for the wearer is therefore essential in the clothing industry. Improving comfort in clothing reviews the latest developments in the manufacturing of comfortable apparel and discusses methods of improving it in various articles of clothing.The book begins by outlining the fundamentals of human comfort in clothing, from the human perception of comfort in apparel and factors which affect it such as the properties of fibres and fabrics, to laboratory testing, analysing and predicting of the comfort properties of textiles. Part two discusses methods of improving comfort in apparel, from controlling thermal comfort and managing moisture, to enhancing body movement comfort in various garments. Part three reviews methods of improving comfort whilst maintaining function in specific types of clothing such as protective garments, sports wear and cold weather clothingThe international team of contributors to Improving comfort in clothing has produced a unique overview of numerous aspects of clothing comfort, provides an excellent resource for researchers and designers in the clothing industry. It will also be beneficial for academics researching wear comfort. Reviews the latest developments in the manufacturing of comfortable apparel and discusses methods of improving fit in various articles of clothing An overview of how to design textiles and garments to maximise comfort begins with factors affecting comfort and properties of fibres and fabrics that contribute to human comfort Improvements in thermal and tactile comfort and moisture management are explored featuring developments in textile surfaces

Book Description
Providing detailed analysis of the thermal comfort assessment of clothing as the basis for developing standards, this book discusses the thermal protective role of clothing as a way of modelling heat transfer from the body, general thermal regulation of humans, and the importance of globally accepted test methods and standards to improve quality. New materials and discoveries in the study of thermal comfort necessitate the need for standard improvements and update. The development of international standards and the unification of testing methods is of crucial significance to ensure cost reduction and health protection. The book promotes instruments, methods, implementation of unified specifications, and the definition of standards so that a clear quality management system can be established, for both production systems and testing methods. It discusses standards in ergonomics of the thermal environment, clothing thermal characteristics, and subjective assessment of thermal comfort, which allows for systematic control of the measuring methods and the services and final products that are distributed on the global market. This book is aimed at industry professionals, researchers, and advanced students working in textile and clothing engineering, comfort testing, and ergonomics.

Book Description
When physical activity and sweating cease in cold environments, it is imperative that the fabrics near the skin return to a dry state as quickly as possible in order to maintain comfort and avoid excessive heat loss. A variety of moisture management fabrics developed for underwear and jacket linings were studied to understand how their finishing treatments, fibre additives, or fibre morphology influenced the thermal properties of winter jackets. Dry and wet underwear fabrics were tested alone and in combination with three-layer jacket systems (i.e. lining, insulation, & shell) on an advanced sweating guarded hot plate in cold ambient conditions (6°C). The wet insulation values and drying behaviour of the fabrics and fabric systems were measured and compared. Fibre content, finishing treatment, and use of hydrophobic linings had a significant effect on wet insulation values. A significant interaction effect between the underwear and lining fabrics was noted on the drying time of cold weather fabric systems and liquid moisture management properties of two-layer composites (i.e. underwear and lining). The air permeability of the lining fabric had a significant effect on the drying time of the cold weather fabric systems.

Book Description
The ability of a clothing system to allow dry and evaporative heat transfer is a n important factor in determining its suitability for a wearing in a given therm al environment. This factor is particularly important when a person has a high a ctivity level and is subjected to heat stress. Although human body models have b een developed with ventilation models, they were mostly based on empirical corre lations for convection in the air layer. In this work, detailed theoretical mode ling of the effect of ventilation on the clothing thermal system was derived. Th e results of the model provided an assessment tool of the affect of clothed human rigorous motion of th e human in relation to occupant thermal comfort. In this thesis, a two- dimensional and three- dimensional thermal models of clot hing ventilation systems were developed. Unlike previous models, these models we re based on thermal principles instead of empirical equations to make these mode ls flexible and practically useful. The 3- D model of microclimate is based on i nertia force Womersley flow in axial and polar directions, while the radial dire ction is lumped using Ghali et al. (2002) normal periodic flow model. The new 3- D model provides a solution of the induced flow due to periodic motion of an in ner cylinder surrounded by an outer cylinder. The outer cylinder represents a po rous fabric. The inner cylinder is solid and represents the skin. The unsteady m ass and energy conservation equations are solved for both the microclimate flow and the air penetrating through the fabric. Results have shown that the presence of open apertures reduces the heat loss from the skin compared with closed aper tures. These results were consistent with published empirical data on highly per meable fabrics. These models can predict the sensible and latent heat loss in di fferent clothing systems. The results are analyzed and were consistent with prev iously published empirical data. Such information would be invaluable in optimiz ing clothing design for comfort in various settings such as for athletes, stage performers and dancers.
