Sažetak
Mehaničko deformaciono ponašanje tekstila može se podeliti na opuštanje tekstila i sposobnost opuštanja. Oba faktora određuju ukupni izgled, estetiku i pristajanje odeće. U simulaciji odeće, ovo ponašanje mora biti simulirano što realističnije kako bi se omogućila značajna procena dizajna i konstrukcije. Važno je razumeti veze između fizičkih svojstava tekstila i opuštanja tekstila. U ovoj studiji, stvarno i simulirano opuštanje tekstila se ispituje i upoređuje. Koeficijent opuštanja služi kao numerička mera. Stvarno opuštanje tekstila prema Cusick-u i simulirano opuštanje tekstila određeni su za tri pamučne tkanine sa različitim konstrukcijama tkanja. Subjektivno poređenje slika procenjuje kvalitet simulacije. Kao rezultat ove studije, može se primetiti značajna devijacija između simuliranog i stvarnog ponašanja tkanine, posebno u pogledu anizotropije tekstilnog materijala. Stoga bi dalja istraživanja trebalo da se fokusiraju na razvoj algoritama za simulaciju koji uzimaju u obzir anizotropnu prirodu tekstila i osiguravaju da simulacije tačno odražavaju ponašanje tkanine u različitim pravcima. Pored potrebe za osiguravanjem pristupa algoritmima za simulaciju, uvođenje standardizovanih metoda prikupljanja podataka je ključno za dalju primenu simulacija u industriji odeće. Koordinisani napor da se definišu ovi standardi i najbolje prakse će olakšati saradnju i omogućiti tačnije i pouzdanije simulacije između različitih organizacija i platformi.
Abstract
The mechanical deformation behaviour of textiles can be divided into textile drape and drapability. Both determine the overall appearance, aesthetics and fit of garments. In garment simulation, this behaviour must be simulated as realistically as possible in order to enable a meaningful evaluation of design and construction. It is important to understand the relationships between physical textile properties and textile fall. In this study, the real and simulated textile drop are examined and compared. The drop coefficient serves as a numerical measure. The real textile drape according to Cusick and the simulated textile drape are determined for three cotton fabrics with different weave constructions. A subjective image comparison evaluates the simulation quality. As a result of this study, a considerable deviation between simulated and real fabric behaviour can be observed, especially with regard to the anisotropy of textile material. Therefore, further research should focus on the development of simulation algorithms that take into account the anisotropic nature of textiles and ensure that the simulations accurately reflect the behaviour of the fabric in different directions. In addition to the need to ensure access to the simulation algorithms, the introduction of standardized data collection methods is essential for the further spread of simulation in the apparel industry. A coordinated effort to define these standards and best practices will facilitate collaboration and enable more accurate and reliable simulations across different organizations and platforms.
