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 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 results obtained in the research programme are of high importance for Slovenia, primarily from the point of view of developing our own knowledge, as well as for the ability to transfer the knowledge into practical application. The results of the research programme will indirectly help the application of the scientific research results in practice, which has already been made real in the case of the developed intelligent system for predicting garment appearance quality InSiNaKVO, the main characteristics of which are as follows: (a) knowledge-based designing and predicting garment appearance quality degree, using known fabric mechanical and physical properties (b) planning fabric mechanical and physical properties so as to get the target garment quality level, and (c) tools to simulate the degree of garment quality. This kind of application is a direct contribution to innovativeness and will be a sound basis of the concept of engineering garment design and/or other textile products that ask for strictly defined functions. Using the methods and tools developed for the purpose this application will help transforming conventional technologies into a high-tech technology, which is of key importance for the long-tern development of the Slovenian garment industry. The research programme results are potentially important for the technological development as well. It is the first attempt for research programmes to include defining all the parameters in the field of garment engineering globally, i.e. from the fabric as the input raw material do the garment, or some other textile product as an end-use product, with the accent of appearance quality, through all the system component, including the aspect or thermal-physiological and ergonomic comfort. The point is in establishing an engineering concept of designing garments or some other textile products, i.e. knowledge-based manufacture and the development of reliable methods and tools that will offer engineering design and construction of garments and other textile products.
