Purpose This paper aims to investigate the performance of four different textile materials used as an outer shell of the bulletproof vest. Design/methodology/approach In this paper, four different textile materials were used, polyurethane treatment was applied as a surface coating for the woven samples. Mechanical properties were conducted for all samples; scanning electron microscope and X-ray energy disperse spectroscopy were executed to show the surface morphology of samples and the chemical composition of the coating material. Findings One-way ANOVA was used to statistically analyse the results, which proved that all variables were highly significantly affected by using different textile materials, despite the stiffness variable being not significantly affected by textile materials. An overall evaluation was done using radar chart, demonstrated that Cordura material accomplished the best functional performance, using two types of calibres 7.62 × 54 mild steel core and 7.62 × 54 armour piercing incendiary; the common mechanism was localized burn because of the incendiary effect of the projectile in addition to tearing mechanism starting from inside because of penetration effect of the steel core. Originality/value This work was addressed to analyse the impact of using four different materials on its performance as the outer shell of bulletproof vest to achieve the desired degree of protection.

“…Today, Cordura fiber is widely used in many application areas such as military clothing, shoes, boots, backpacks, workers' clothing, suitcases, tent cloth and musical instrument bags due to its advanced abrasion resistance, tear strength and flame retardancy properties. [10][11][12] In this study, in order to overcome the poor tear and abrasion resistance in thin wool/Lycra fabrics, Cordura fiber, which shows high performance against tearing and abrasion, was integrated into wool and wool/Lycra yarn structure with different fiber percentages. All the yarn samples were tested according to related the standard methods to evaluate yarn quality properties such as breaking force, breaking length (RKM), elongation at break, unevenness (CV%), yarn imperfection (thick, thin places and neps) and hairiness.…”

Cordura fiber, which has high performance against tearing and abrasion, can be used to improve the tear strength and abrasion resistance of low-weight wool/lycra fabrics that can be suitable for daily wear. Thin wool fabric is very comfortable to wear, but lighter fabrics are more prone to appearance problems, since they are less able to resist the forces responsible for the distortions. This study aims to investigate the effect of cordura fiber integration on the yarn quality properties of wool and wool/Lycra yarn. Cordura fiber was integrated into wool and wool/Lycra yarn structure with different fiber percentages and were tested according to related the standard methods to evaluate yarn quality properties such as breaking force, breaking length (RKM), elongation at break, unevenness (CV%), yarn imperfection (thick, thin places and neps) and hairiness.

Purpose The purpose of this work is to perform an application study on experimental animals (dogs) to investigate the efficiency of using weft knitted mesh fabric as cardiac support mesh to support left ventricular hypertrophy. Design/methodology/approach In this work, weft-knitted mesh sample “Knitted Cardiac Support Mesh” manufactured using Nylon (6, 6) yarns, with count 20 Denier and medium mesh size, was placed around the two ventricles to prevent further dilatation, support and reduce left ventricular wall stress. Findings Medical textile is a rapidly expanding field in technical textiles that are widely used in a variety of medical applications. One of these medical textile applications is “Knitted Cardiac Support Mesh”, which is used in the treatment of Dilated Cardiomyopathy. Originality/value After the implantation of the manufactured Knitted Cardiac Support Mesh around the myocardium, all dogs survived for three months before being euthanized, and some clinical examinations were performed to investigate and evaluate the sample performance. It was demonstrated from the experimental application, that the nylon mesh sample performed the best during the surgical operation due to its good ability to stretch and recover at a moderate rate, as well as the textile mesh lightweight.
