The paper examines the washing behavior of fabric by using the finite element method (FEM) along with the Coupled Eulerian–Lagrangian (CEL) approach. Many prototypes of e-textiles with different functions have been developed for various applications in laboratories worldwide, but only a limited number of products exist on the market. The washing process, even for mild wash cycles, damages mainly conductive yarns and electrical contacts on wearable fabrics. A hydrodynamic simulation method is proposed to investigate the mechanical response of fabric during a washing cycle, using the FEM and CEL approaches with the Abaqus finite element solver. The FEM is described with the following inputs: the fabric properties; the Mie–Grüneisen equation of state (EOS) for water; the ideal gas EOS for air; the geometry of the model; the drum spin data; and the boundary conditions. The movement of fabric inside the drum and reaction forces on the drum are utilized to verify the simulations. The fabric movements that are attributed to be the reason for damage in a conductive yarn showed a typical washing response. The frictional dissipation energy results show different regions depending on the motion and interaction of the components inside the drum. Also, the contact forces were determined. These forces can be input for future damage modeling studies. The findings of the study are expected to be used in development phases of reliable e-textile products with an extended life of service and readiness for the market.

“…Inflatable structures made of membrane materials have been widely applied in many fields, such as construction, protection, aerospace, and the automotive industries. [1][2][3][4][5][6] The compressive performance of the inflatable membrane material is determined by the cooperation of the membrane body and the internal air pressure. [7][8][9][10] At present, the membrane body is usually made of polyvinyl chloride (PVC) membrane or PVC-coated two-dimensional fabric material.…”

“…13 Because of their excellent characteristics such as lightweight, high strength, designability, and portability, high-distance spacer fabric flexible inflatable composites, which are prepared by compounding fabric (generally refers to a spacer fabric with spacer filaments more than 50 mm) 14 with PVC, are widely used in inflatable building, tents, aircraft wings, boats, and other consumer industries. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] In contrast with conventional spacer fabrics, the spacer yarns' main role in the highdistance fabric is to serve as a connecting pile in the fabric and allow the fabrication of inflatable composites with more complex cross-sectional geometries. [18][19][20] Therefore, the high-distance spacer fabric flexible inflatable composites can bear the loading by stabilizing the shape and rigidity of the structure.…”

High-distance woven spacer fabrics have been developed into a variety of special textile products for a wide range of applications. As a type of sandwich structure, their applications are heavily dependent on their compressive properties. In this study, the compressive properties of high-distance woven spacer flexible inflatable composites (HDWSFICs) have been evaluated by varying the indenter diameter, initial inflation pressure, and spacer yarn density. The experimental results showed that the compression process can be divided into three stages, including the Contact Stage, the Stress Transition Stage and the Densification Stage. In the Stress Transition Stage, the HDWSFICs can transform compressive load into tension stress, and especially local stress into integral stress, which can be considered a “Stress Transformer”. The existence of the spacer yarns allows the inflatable composites to bear more than three times the compressive load of the inflatable membrane material itself. The compressive modulus increases with spacer yarn density and initial inflation pressure, thus the stiffness of HDWSFICs can be designed. The findings of this study may provide ideas for the design of a “Stress Transformer” and theoretical references for the development of high-distance woven spacer inflatable composites with excellent mechanical properties.

“…The RMM, which is based on graphical deformation, first shifts some of the constraint nodes regularly while the rest of the adjacent nodes have a certain displacement due to the pulling of the constraint nodes, which achieves the fold modeling of an inflatable fabric. Liu et al 13 first used the RMM to build a folding model for a cylindrical surface that had good mesh quality and regular folds. However, the RMM can only be applied to simple developable three-dimensional surfaces (such as cylinders).…”

At present, most space inflatable structures are composed of flexible inflatable fabrics with complex undevelopable surfaces. It is difficult to establish a multi-dimensional folding model for this type of structure. To solve this key technical problem, the motion folding method is proposed in this study. First, a finite element model with an original three-dimensional surface was flattened with a fluid structure interaction algorithm. Second, the flattened surface was folded based on the prescribed motion of the node groups, and the final folding model was obtained. The fold modeling process of this methodology was consistent with the actual folding processes. Because the mapping relationship between the original finite element model and the final folding model was unchanged, the initial stress was used to modify the model errors during folding process of motion folding method. The folding model of an inflatable aerodynamic decelerator, which could not be established using existing folding methods, was established by using motion folding method. The folding model of the inflatable aerodynamic decelerator showed that the motion folding method could achieve multi-dimensional folding and a high spatial compression rate. The stability and regularity of the inflatable aerodynamic decelerator numerical inflation process and the consistency of the inflated and design shapes indicated the reliability, applicability, and feasibility of the motion folding method. The study results could provide a reference for modeling complex inflatable fabrics and promote the numerical study of inflatable fabrics.
