Physical-mechanical phenomenon of woven and non-conventional materials

Abstract

The basic idea of this project is in developing series of methods for monitoring structural parameters, as well as establishing their relation with the behaviour of woven and non-woven materials. Establishing the connection among structural parameters of material (constructive elements, their position and distribution, construction) and their behavior during special conditions of usage, through monitoring the phenomenon of physical-mechanical characteristics and resistance mechanisms, contributes to establishing the relation for developing complex methodology of projecting textile surfaces. Investigation of textile complexes as porous and flexible systems represents the basis for establishing functional dependence "fibre-textile complex-final product" type. This is possible to achieve through the analysis of textile surface state and its topography, as well as constructive solutions and physical-mechanical characteristics. Analytic investigation of characteristics, such as flexibility and resistance to various strains, was conducted on woven fabrics and non-woven materials of various constructions aimed at establishing their basic models. The main focus is on mechanical characteristics, especially elastic properties under action of various loads (tensile, bending, pressure). Relaxation processes and recovery kinetics are particularly investigated. Making the connection between structure and mechanical characteristics enables the projection of the expected or desired behavior of woven fabrics. Besides, establishing criteria for estimation of the total elasticity, as the magnitude of quality index and its valorization, represents the possibility for establishing objective methods of woven and nonwoven materials of functional characteristics.
