A new computer geometric modeling approach for 2x2 twill woven fabrics structures has been presented. A 3D model considering their inherent skewness is proposed and can be used in precise geometrical description. Balanced fabric geometry occurs in 2x2 twill weaves where the fabrics are defined by floating and intersecting segments in weaves, which create symmentric floatings on the front and back surfaces of the fabrics. The yarns cross-section of twill woven fabrics uses the concept of virtual locations and each cross-section is rotated along a single yarn path. The curve of each filament in each of two successive cross-sections is approximated by NURBS. The approach described is demonstrated in 3D CAD for twill woven fabrics structures by using the geometric parameters considering their inherent skewness. The simulated twill woven fabrics structures must be improved so that they are a true visual simulation of real twill woven fabrics and can demonstrate wide varities of form.

Abstract


A new computer geometric modeling approach for 2x2 twill woven fabrics structures has been presented. A 3D model considering their inherent skewness is proposed and can be used in precise geometrical description. Balanced fabric geometry occurs in 2x2 twill weaves where the fabrics are defined by floating and intersecting segments in weaves, which create symmentric floatings on the front and back surfaces of the fabrics. The yarns cross-section of twill woven fabrics uses the concept of virtual locations and each cross-section is rotated along a single yarn path. The curve of each filament in each of two successive cross-sections is approximated by NURBS. The approach described is demonstrated in 3D CAD for twill woven fabrics structures by using the geometric parameters considering their inherent skewness. The simulated twill woven fabrics structures must be improved so that they are a true visual simulation of real twill woven fabrics and can demonstrate wide varities of form.
