Proposing a virtual simulation method to predict the shape-fidelity of 3D-knitted-textiles using knit-meshes and geometric invariants

Abstract. Though the level of machine digitization in flatbed-knitting (FBK) today is high, design and development knittable data sets are still currently very time-consuming, digital simulations methods calculation expensive insufficient terms accuracy fit technical properties. Knitting process retrofitting activities executed mostly manually by an operator on basis operator´s experience. This circumstance makes it more difficult to use diverse potential for flexibility on-demand purposes future-networked-production lightweight constructions Automotive, Aerospace aviation or Medical-Products. New easy-to-learn, intuitive, inexpensive augmented workflows planning knitted objects with complex 3D-shapes needed. With regard requirements composite forming, aspects wrinkling, slip permeability particular importance. However, flatbed-knitted fabrics subject different some cases, which implies questions from those posed research area woven textile composites. In order address a few raised previous composites, this paper covers current topics field 3D-knitted shows references as well potentials already researched problem fields reinforced doing so, author strongly refers summarizing publication "Advances forming through 25 years ESAFORM" P.
