“…The effect of blend ratio, mass per unit area and needling density on the tensile properties of polyester/viscose blended nonwovens was investigated. In conclusion, the regression model indicated that the tensile strength of the needle-punched nonwovens decreases with the increase of polyester proportion in the mixture and increases with the increase in mass per unit area and punching density (7). Rawal predicted the tensile behavior of nonwoven structures including needle punched and thermal bonded by modifying the micromechanical model based upon the geometrical and mechanical properties (8).…”

In this study, the dry and wet strengths of standard/recycled and plain/patterned nonwoven products with weight variation are studied. In the first part of the study, the machine and cross direction strengths of the standard and recycled products of the same unit weight were tested in dry and wet conditions. And the efffect of weight variotion on the strength is investigated. In the second part of the study, the strengths of the plain and patterned products in the machine direction and crosswise direction of the same unit weight were tested in dry and wet state. The effect of patterning on the strength is tried to find out. Study's mathmatical and statistical results show that in terms of sustainability, it has been concluded that viscose/polyester blended recycled nonwoven produc ts can be used instead of standard fabric by increasing the unit weight. Also, patterning does not cause strength loses.

“…There are various studies investigating the tensile properties of nonwovens (6)(7)(8)(9)(10)(11)(12). Ray and Ghosh studied the fibre cross laying as well as fibre orientation angle in cross-laid needlepunched nonwoven fabric and its relationship with tensile properties of fabric.…”

“…The fibre blend composition affects the tensile and tear strength of a needle-punched nonwoven by determining the inter-fibre bonding within the nonwoven structure [5,16,17]. By combining different types of fibres with varying characteristics, such as high-strength fibres and low-strength fibres, the overall tensile strength of the fabric can be enhanced or tailored to meet specific requirements.…”

This research investigated the innovative synthesis achieved through blending five distinct fibres (Polyacrylonitrile (PAN), Polyester (PET), Polylactic acid (PLA), Polypropylene (PP), and Polyphenylene sulfide (PPS)) in the production of needle-punched nonwoven fabrics tailored for air filtration applications. The study investigated the effects of needle-punched nonwovens made with up to five fibres on the physical and mechanical properties, addressing a gap in existing literature. The method involved manual and machine opening, blending, and carding of fibre s, followed by producing three samples with different web arrangements (cross laid web, parallel laid web, and pre needled parallel lad web). The study employed standard test methods to characterize physical and mechanical properties. Results indicated that web arrangement and pre-needling significantly influenced various properties, with cross and parallel-laid web arrangements having minimal impact on thickness and bursting stretch. The parallel arrangement, whether pre-needled or not, showed no significant effect on GSM, fabric density, bursting strength, tear strength, abrasion resistance, and filtration efficiency. The highest abrasion resistance, lower pressure drop, highest fabric stiffness, moderate tensile strength, and higher bursting strength were observed in a cross-web arrangement. This study contributed valuable insights into the intricate interplay of fibre composition, web arrangement, and pre-needling in the design of advanced needle-punched nonwoven fabrics for air filtration. The findings provided a nuanced understanding of how these factors collectively impact the mechanical and physical characteristics of the material, paving the way for enhanced efficiency, durability, and versatility in air filtration applications.

“…Mechanical tests have been used in order to characterise the mechanical properties of fabrics: relaxation or tensile tests [7, 8, 9, 10, 11], sometimes using different speeds [12], or non-uniaxial tensile test [13]. Studies investigated the fabric weaving [14, 15, 16] as well as different manufacturing methods [17] or the effect of physicochemical treatments [18, 19]. They are also used to validate finite element models of fabric [20].…”

In-silico pre-clinical trials are made possible by a new simple and comprehensive lumbar belt mechanical model based on the Law of Laplace including support deformation and adhesion effects

Lower back pain is a major public health problem. Despite claims that lumbar belts change spinal posture due to applied pressure on the trunk, no mechanical model has yet been published to prove this treatment. This paper describes a first model for belt design, based on the one hand on the mechanical properties of the fabrics and the belt geometry, and on the other hand on the trunk geometrical and mechanical description. The model provides the estimation of the pressure applied to the trunk, and a unique indicator of the belt mechanical efficiency is proposed: pressure is integrated into a bending moment characterizing the belt delordosing action on the spine. A first in-silico clinical study of belt efficiency for 15 patients with 2 different belts was conducted. Results are very dependent on the body shape: in the case of high BMI patients, the belt effect is significantly decreased, and can be even inverted, increasing the lordosis. The belt stiffness proportionally increases the pressure applied to the trunk, but the influence of the design itself on the bending moment is clearly outlined. Moreover, the belt/trunk interaction, modeled as sticking contact and the specific way patients lock their belts, dramatically modifies the belt action. Finally, even if further developments and tests are still necessary, the model presented in this paper seems suitable for in-silico pre-clinical trials on real body shapes at a design stage.
