Investigation of automated geometry modeling process of woven fabrics based on the yarn structures

Fabric structure has a significant effect on the thermal protective performance of fabrics. Before studying the thermal performance of textiles by numerical methods, it is essential to create geometric models of textile structures. Common fabrics, such as plain weave, 2/1 twill, 3/3 twill, 5/3 satin, and double layer fabric, were modeled using TexGen software. To obtain the input data for geometry simulation of fabrics, geometric measurements were studied. Methods of modeling fabric geometries according to their yarn path function and cross-sectional shapes were introduced. The appearances of the geometric models were very close to the structures of the real fabrics when compared to their light microscopic images. The fabric models were well used to simulate the heat transfer properties of glass fiber fabrics.
