Abstract
The investigations proposed by the programme group, based on a complex research of woven fabric mechanics, material properties and the relation of material properties and the parameters of thermal-physiological comfort, is organised, having in mind the aims proposed, in three closely connected sets:
a) basic investigations of the mechanics of woven fabrics as complex textile structures,
b) modellling the behaviour of complex textile structures, and
c) characterising the parameters of thermal-physiological comfort.
The first set of activities is based on the knowledge of mechanical laws of fabric behaviour at low loads and is aimed at defining the quality properties of garment form appearance. Fabric behaviour from the point of view of mechanics in processing from a plane into a 3D garment shape is determined, the importance of individual parameters of mechanical and physical properties is evaluated and a knowledge basis used to predict garment appearance is constructed. Based on the laws defined and appearance quality factors, we have developed the »Intelligent system for predicting garment appearance quality«, called InSyPrGAQ, or InSiNaKVO by Slovenian acronym. InSiNaKVO system is designed using the method of machine learning and represents an innovation – the first effective tool for objective evaluation and prediction of the degree of garment appearance quality. The system is based on the ratio among the parameters of mechanical and physical properties and the degree of garment appearance quality, and it is aimed at predicting the degree of garment appearance quality on the basis of the parameters of mechanical and physical properties of the fabrics built into the garment evaluated. It offers:
• objective evaluation of the garment appearance quality degree,
• predicting five key factors of garment appearance quality degree: garment drape or fall. 3D form, fitting, the quality of the seams and garment appearance quality as a whole,
• planning the target degree of garment appearance quality,
• predicting garment appearance quality degree for particular fabrics in a direct manufacturing process,
• planning the parameters of fabric mechanical and physical properties for the target degree of garment appearance quality.
The system developed fulfils completely one of the aims of the research programme for the group. The idea was presented at the Slovenian Innovation Forum 2006, and it will be included in the catalogue of national innovations. Simultaneously, we have taken adequate steps in protecting the contents of the idea and intellectual property, applying for the patent rights.
The set of activities involving modelling complex textile structures deals with continuation of the investigations of complex fabric deformations, with the accent on studying rheological models. Fabric relaxation is here studies from the point of view of mechanical multi-component models, which are able to describe in a satisfactory manner deformation and relaxation profecces in fabrics, this being the starting point for numerical modelling of fabric behaviour, fabrics being complex textile structures.
The third set of investigations deals with the characterisation of thermal-physiological comfort parameters. Comprehensive research of heat transfer and flow, as well as thermoregulation, together with the investigations of textile material properties have been performed. Investigations of material properties and specific requirements imposed on textile materials of a particular target group have been performed for convetional and functional fabrics, as well as for the combinations, aimed at planning garment systems of business suits. The research is organised at three levels. The first includes investigations of thermal-physiological parameters on so called sweating cylinder for the selected fabrics and combinations of the planned garment systems. The sweating cylinder simulates the functioning of human body allowing heat flow through
Significance for science
The research programme is systematically designed so as to result in the knowledge that could be used in establishing and engineering concept of garment and/or other textile product planning particularly the so called »knowledge-based products«. Realisation of the research programme proposed is offering, using the theoretical knowledge obtained by investigating fabric mechanics and the theory resulting from it, as well as numerical and physical experiments, new knowledge than will enable prediction of non-linear fabric mechanical properties in the area of low loads, as well as the simulation of fabric behaviour. The theoretical knowledge obtained by studying the relation among textile material properties, heat exchange and human body thermoregulation, will result in the development of a numerical simulation for heat exchange among the body and garment or some other textile product, and the environment, which is a clear trend in further development of textile and garment engineering globally. The development is aimed at the parameterisation of textile materials, engineering design of high-quality and multifunctional textile materials and products, numerical simulation of their behaviour and virtualisation on one hand and ensuring thermal-physiological comfort on the other. The obtained knowledge contributes to the development of basic knowledge in the field of garment engineering and is important for the scientific development both in Slovenia and globally. The fundamental knowledge will contribute to the development of innovative textile materials with functional purposes, i.e. knowledge-based products, as well as to the development of the necessary technologies to manufacture them.
Significance for the country
The research results, which content is focused on setting-up the engineering concept for clothing design and/or other textile products that require defined aesthetic, thermal and physiological and/or functional properties, i.e., knowledge-based products, is important for textile/clothing branch, development of the branch, as well as for the engineering praxis. The transfer of achieved scientific cognitions into the praxis enables engineered design of the clothing system or other textile products as systems, as well as design of multifunctional and/or intelligent/smart garments and other textile products. This kind of application may directly contribute to innovativeness. Engineered concept of design of clothing and/or other textile products that require defined functions may, using developed appropriate methods and tools, result with transformation of conventional to high-tech technologies, which is of extreme importance for sustainable socio-economic development of the Slovenian clothing industry. On the other hand, the research achievements will be equally integrated into the world treasury of knowledge. They will enable better linkage of Slovenian scientists and through them also manufacturers of garments and other high-quality textile products with scientists and professionals in the world, which will strengthen the presence of Slovenian experts and producers in the world market. Because the research includes the definition of all the parameters in the area of clothing engineering in a global sense, i.e., from input textile materials up to the garment or other textile product as a final good throughout all of the components of the system, it also includes the aspects of thermophysiological, mechanical and ergonomic comfort, the research results are of direct importance for wider society and for social infrastructure.
