Improvement of Drape simulation speed using constrained fabric collision
International Journal of Clothing Science and Technology, 2004Co-Authors: Tae Jin KangAbstract:Garment is generally a 3D object made of 2D fabric. So, it is necessary to predict the Garment Drape shape when designing fabric patterns. There are several methods to simulate fabric Drape, but the calculation times are long for practical use. The bottleneck of the Drape simulation is the collision detection between fabric and human body and self contact detection of the fabric itself. We assumed that the fabric collision occurs only locally to reduce the number of possible collisions. We made the fabric patterns into finite elements and each element was given a local area number so that only elements within certain area can contact with other ones.

development of three dimensional apparel cad system part ii prediction of Garment Drape shape
International Journal of Clothing Science and Technology, 2000Co-Authors: Tae Jin KangAbstract:A fast response three dimensional Garment Drape shape prediction system has been developed. A human body model generator has been established for the Garment draping on it. For the mass production of different size of Garments for the various sized body models, the cross‐sectional value from the anthropometric data was used as the standard for the size accommodation to make a resizable human body model. To construct the cloth Drape shape prediction system, the finite element analysis method has been utilized. The designed Garment pieces were divided into fine quadrilateral elements using a specially coded mesh generating program, then some appropriate sewing conditions were assigned to transform two dimensional patterns into three dimensional shapes. The final Drape shape of the Garment was determined from the solutions of the contact condition with human body, deformations, and the weights of the elements constituting the Garment pieces, as well as the surface texture of the cloth.

an investigation on the virtual prototyping validity simulation of Garment Drape
SOCIETY. INTEGRATION. EDUCATION. Proceedings of the International Scientific Conference, 2018Co-Authors: Eva Lapkovska, Inga DabolinaAbstract:Achievement of desired Garment form is essential in the development of clothing design, which depends on properties of its raw material - mainly fabric. Virtual prototyping can serve as a tool for assessing the form and fit of Garments before real production and deciding whether to make changes in ease values, pattern cut or fabric parameters. The aim of the study is investigation of reliability of virtual prototyping results using Modaris 3D (Lectra) due to influences of changeable fabric parameters on Garment Drape effects, as well as verifiability with three-dimensional (3D) scanning (Vitus Smart XXL®) of real products. For the research half-circle cut skirt designed in appropriate size for standard figure dummy. Skirt virtually simulated on mannequin which previously scanned and imported into the system. Properties of three different types of fabrics examined in a material testing laboratory according to requirements of relevant standards. Skirt virtually tried-on defining fabric properties by gained testing results and afterwards made from real fabrics, put on the dummy and scanned. Drape effects of the various virtual prototypes and real product scans compared, both in the CAD system and the scanning system (Anthroscan) using cross-sections and their measurements (depths and diameters of folds, circumferences). Fabric parameters has an influence on the reliability of virtual prototyping results in terms of accuracy of parameters determined and put into the system. Cross-sections with measurements reveal differences between virtually sewn and real skirt Drape configurations.

investigating Garment Drape behaviour
Journal of Fiber Bioengineering and Informatics, 2015Co-Authors: Reham Sanad, Tom CassidyAbstract:Drapeability is one of the most important visual properties affecting Garment appearance. Even though there are many studies concerned with fabric Drape, understanding about the Drape behaviour of Garments is very limited. This study analyzes the key properties affecting the Drape behaviour of Garments to provide prediction equations. Results are statistically analyzed. From multiple regression analysis, Drape rank scores obtained from subjective analyses are predicted using weight, bending modulus and extensibility measured at 100 gf/cm with a correlation coefficient of 0.94. Ranking values obtained from subjective analyses can be more easily predicted using both circularity and wave length minimum. A new equation was derived to predict Drape rank score values of Garments (correlation coefficient r = 0.97) depending on circularity and wavelength minimum.

fabric and Garment Drape measurement part 2
Journal of Fiber Bioengineering and Informatics, 2013Co-Authors: Reham Sanad, Tom Cassidy, Vien Cheung, Elaine EvansAbstract:Fabric and Garment Drape were compared using an alternative Drape measurement system based on an image analysis technique. Garment Drape was investigated using dresses suspended on a mannequin. A graphical user interface was developed to carry out the image analysis and to calculate Drape values identifying and determining 21 parameters. A range of fabrics including knitted, woven and nonwoven fabrics were compared in terms of FAST properties, Drape coe‐cient and Drape values. Visual assessment of the fabric range was carried out in terms of Drape amount and preference. Low agreement was found between individuals with regard to preferred Drape amount and high agreement with respect to actual Drape amount. Nonwovens were found of better preference over some traditional fabrics. Most of the Drape values of fabric and Garment were found to have poor correlations.

The measurement of Drape for nonwoven and conventional textile fabrics
2013Co-Authors: Reham SanadAbstract:The importance of the Drape properties of fabrics on final Garment appearance and fit has been long understood and a great deal of research has been carried out in this area. More recently, nonwoven fabrics have begun to create interest among the apparel and fashion design community. In this study, the conventional method of measuring fabric Drape was compared with Garment Drape measurement using an alternative Drape measurement system based on an image analysis technique. Garment Drape was investigated using dresses suspended on a mannequin. A Garment chosen was a shift dress because of its relatively uncomplicated style and shape. Hydroentangled nonwovens were selected as they show good performance and similarity to conventional fabrics in terms of physical and mechanical properties. A graphical user interface was developed to carry out the image analysis and to calculate Drape values identifying and determining 23 Drape parameters. A range of fabrics including conventional (knitted, woven) and nonwoven fabrics were compared in terms of FAST properties, Drape coefficient and Drape values. Some nonwoven fabrics were found to give similar performance to some conventional fabrics and better than others. Subjective assessment of the fabric range was carried out in terms of Drape amount and preference. Low agreement was found between individuals with regard to preferred Drape amount and high agreement with respect to actual Drape amount. Nonwovens were found to be better preferred over some conventional fabrics. Most of the Drape values of fabric and Garment were found to have poor correlations.

fabric and Garment Drape measurement part 1
Journal of Fiber Bioengineering and Informatics, 2012Co-Authors: Reham Sanad, Tom Cassidy, Vien CheungAbstract:This paper aims to make a comprehensive review of measurement methods developed for evaluating fabric and Garment Drape. Drapemeters used for evaluating Drapeability since Pierce's bending length tester are reviewed. Parameters proposed for measuring Drapeability are also considered. The authors propose that using flat fabric methods does not accurately reflect the Drape of fabrics when worn. The paper is a pre-cursor to a new image analysis technique which will be reported in Part 2.

Development of a platform for realistic Garment Drape simulation
Fibers and Polymers, 2006Co-Authors: Chang Kyu ParkAbstract:An integrated platform for Garment Drape simulation system has been developed. In this system, Garment patterns from conventional two-dimensional CAD systems can be assembled into a three-dimensional Garment on a parametrically resizable realistic human body model. A fast and robust particle-based physical calculation engine has been developed for Garment shape generation. Then a series of geometric and graphical techniques were applied to create realistic impressions on simulated Garments. This system can be used as the rapid prototyping tool for Garments in the future quick-response system.

Parametric body model generation for Garment Drape simulation
Fibers and Polymers, 2004Co-Authors: Chang Kyu ParkAbstract:A parametric body model generation system has been developed. Using various mathematic and geometric algorithms of this system, a three-dimensionally scanned human body can be converted into a resizable body model. Once a parametric body model is formed, its size and shape can be modified instantaneously by providing appropriate anthropometric data. To facilitate the subsequent pattern arrangement process for Garment Drape simulation, a bounding box generation algorithm has been developed in this study. Also the model can be converted into a set of parametric surfaces that it can also be used for three-dimensional Garment pattern design system.

Fast Garment Drape simulation using geometrically constrained particle system
Fibers and Polymers, 2003Co-Authors: Chang Kyu ParkAbstract:A simulation system for versatile Garment Drape has been developed. Using this system, the shape of a Garment can be simulated in consideration of fabric physical properties as well as the interaction between fabrics and other objects. Each fabric piece in a Garment is modeled using a geometrically constrained particle system and its behavior is calculated from an implicit numerical integration algorithm in a relatively short time. The system consists of three modules including a preprocessor for the preparation of fabric patterns and external objects, a postprocessor for the results of three-dimensional visualization, and a Drape simulation engine. It can be used for the design process of textile goods, Garments, furniture, or upholsteries.
