  • Advances in diabetic footwear and plantar pressure distribution devices: literature review on design, efficacy, and patient outcomes

    Industria Textila, 2025
    This literature review aims to explore the significance of diabetic footwear in managing foot-related complications associated with diabetes, especially related to diabetic neuropathy, peripheral arterial disease, and ulcerations. The goal is to synthesise key research on the design, efficacy, and impact of diabetic footwear in preventing foot ulcers, reducing pressure, and promoting healing. The review highlights recent advancements in diabetic footwear technology, including innovations such as smart sensors and other industry 4.0 advancements, while also addressing the barriers to patient compliance and the challenges in evaluating long-term outcomes. Special considerations are addressed to publications and authors in the field of diabetic research as their continuous impact drives knowledge forward and provides relevant data in improving patients’ quality of life. Findings show that diabetic footwear plays a critical role in preventing foot complications, but further research is needed to standardise footwear designs and assess long-term benefits.
  • Impact of pattern lines and technological features on the behaviour of vamp-over-quarter footwear type

    Industria Textila, 2025
    This article aims to demonstrate how the positioning of the seam line between the vamp and quarter and the number of stitches affect the joint strength and overall performance of the product during walking. The configuration of analysis conditions and constraints was conducted using ANSYSTM. The gait biomechanics were considered to establish the load model, including the distribution of forces, their magnitudes, and constraints. The analysis focused on the three phases of gait: heel strike, mid-stance, and push-off, evaluating three key parameters: directional displacement, Von Mises stress, and elastic deformation. The study emphasises how directional displacement, stress distribution, and elastic deformation change based on the gait phase and the materials used in the construction of the selected footwear type. Using a two-stitch seam to join the components promotes directional displacements and reduces stress/tension compared to a single-stitch seam. Positioning the seam line between the vamp and quarters along the toe line increases stress/tension in the front section of the shoe. The analysis was validated by comparing simulation results with average plantar pressures obtained from a biomechanical assessment of plantar pressure distribution.
  • The Influence of Materials on Footwear Behaviour: A Finite Element Simulation Study
    Arina Seul, Aura Mihai, Mariana Costea, Alexandra Bodoga, Antonela Curteza
    Materials, 2023
    The objective of this study was to analyse the influence of materials and their position within the upper assembly on the behaviour of casual footwear using finite element simulation tools. The study was carried out on three models of casual footwear, which are identical in terms of design lines, varying only in the materials of the upper assembly, namely calfskin leather (M1), knitted fabric (M2), and combination of knitted fabric and calfskin leather (M3). The footwear models were designed according to the design constraints specific to casual footwear. The foot was reconstructed based on the shoe last obtained based on anthropometric data. Material definition, 3D models editing, setting up analysis conditions, and constraints were performed using the Ansys 17.2 software. Gait biomechanics were taken into account to define the loading model, force distribution, force values, and constraints. The study evaluates footwear behaviour in terms of directional deformation (Z axis), equivalent von Mises stress, and equivalent elastic strain distribution. This paper explores a methodology that has the potential to enhance the footwear design and manufacturing process, providing designers with information about the deformations and stress distribution on upper parts of the footwear product.
  • Ozone–Vacuum-Based Decontamination: Balancing Environmental Responsibility and Textile Waste

    Sustainability Switzerland, 2023
    This study explores the use of ozone decontamination as a sustainable approach for eradicating pathogens from various environments. Ozone, a highly reactive gas, demonstrates remarkable efficacy in eliminating bacteria, viruses, and fungi. Decontamination of textile materials using an innovative ozone treatment method conducted under vacuum conditions has been investigated. A hybrid apparatus comprising a vacuum and an ozone generator was employed for the decontamination process. Ozone decontamination offers environmental benefits by avoiding harmful by-products and minimising long-term environmental exposure. However, challenges include the need for proper equipment and training to ensure safety and effectiveness. This research underscores the promise of ozone decontamination as a powerful and eco-friendly method for pathogen eradication in textile materials with future developments in diverse settings.

  • Slit tear resistance of leather used in upholstery manufacturing
    MARIANA COSTEA, ARINA SEUL, AURA MIHAI
    Industria Textila, 2023
    The paper presents experimental research on the slit tear resistance of leather used for producing upholstery. A finite element analysis is done by simulating the product's behaviour, considering different factors and parameters, and materials are classified according to the normal stress results. The maximum force exerted during the tearing of the specimen has been observed at the SATRA tensile testing machine, with STM 466ST attachment and digital software control. The load at break, the extension at break, Young's Modulus, and the load-distance graphs were registered and the medium values were calculated. The Taguchi method based on orthogonal arrays was used to maximize the material characteristics significant for this type of analysis.

  • Mechanical Parameters of Leather in Relation to Technological Processing of the Footwear Uppers
    Aura Mihai, Arina Seul, Antonela Curteza, Mariana Costea
    Materials, 2022
    This paper aimed to define two critical mechanical properties of leather—Young’s modulus and Poisson ratio—essential to the virtual simulation of the behaviour of the footwear uppers against the manufacturing operations of stitching and perforating. The following technological aspects were considered to analyse the materials from manufacturing conditions point of view: the number of layers (one layer and two layers), the nature of the materials used for uppers subgroups (calfskin-outer upper, sheep leather-lining, polyester knitted fabric-lining), the overlapping width in the stitching area, the number of parallel stitches (single stitch and double stitch), the punching interval and the type of perforations (simple and with eyelets), resulting in nine kinds of samples. Furthermore, the elasticity (Young’s modulus) and lateral contraction (Poisson’s ratio) were calculated during the tensile strength analysis performed on the SATRA STM 466 equipment. Both mechanical parameters are essential to simulate the behaviour of the virtual footwear prototypes in various conditions.
  • PLANTAR FOOTPRINTS AND 3D FOOT SHAPE DIGITAL ANALYSIS FOR OVERWEIGHT TEENAGER – ONE CASE STUDY

    Leather and Footwear Journal, 2022
    Nowadays, one of the most critical health problems among young people is obesity. Because teenagers are still in the growing process, the foot shape and plantar footprints are very important to be analysed and potential problems to be identified. Young adulthood is a risky period for the development of obesity. This study aims to analyse the plantar footprints, the biomechanical parameters obtained through plantar pressure measurements, and the 3D shape of the foot and anthropometrical parameters obtained from scanning. By comparing the results, both feet have been demonstrated to be high arched, as well as high pressures were identified and differences from left to the right foot. With these results, prophylactic footwear and components can be designed, adapted to the subject’s feet.
