Abstract
This investigation is undertaken based on the indicated improvements for fabric simulations. According to the expert opinions, there is no coherency between methods used to measure the fabric properties and the simulated results of the same fabric among the different software packages. In praxis, fashion brands use different 3D software packages and need to measure a fabric with different methods to obtain the same fabric properties. In addition to the time investment, the simulated results for the same fabric vary significantly between the different software packages. The experts indicated the lack of standardization in material measurements, the lack of correlation between the data of the different measurement systems, and the lack of correlation between the simulated results of the different software packages for the same material. This paper investigates, on the one hand, the suitability of the two measurement technologies for retrieving fabric parameters for precise virtual fabric and garment simulations. The focus is on the main properties required by the software packages - bending, shear, tensile and friction-aiming to identify and specify the most suitable methods to retrieve mechanical fabric properties and to start a standardization process for fabric measurements for virtual simulations.

Even if it is impossible to simulate a product with 100% accuracy since all real influencing factors cannot be known, the virtual prototype has to be precise enough so that important decisions can be taken within the product development process
Thickness at 0.5 gf/ cm[2] mm Besides his studies on the standardization of objective fabric hand assessment, Kawabata went on with research on measuring mechanical and physical fabric properties. This part of research was driven by the question of how a broad variety of fabrics should be tested in the same way so that the obtained data represents a significant statement about that textile
Summary
The fashion industry has been increasingly shifting to use simulations for virtually assessing new products before they are produced [1-3]. Even if it is impossible to simulate a product with 100% accuracy since all real influencing factors cannot be known, the virtual prototype has to be precise enough so that important decisions can be taken within the product development process. Depending on the field of application, simulations approach reality with various mechanical models that consider forces and impulses and reduce the influencing factors to the most important ones. Fabrics are complex non-linear viscoelastic materials that, when subjected to stress, flow and only gradually come to rest when the force is removed. Their simulation is not easy, as their behavior is difficult to describe and predict. The accuracy of virtual garment simulations is dependent on the mechanical model of the simulation system and the precision of fabric input parameters, derived from fabric physical and mechanical fabric properties [4−15]
